1. Don't put car in neutral driving downhill 2. Come to full stop before changing directions (drive/reverse) 3. Don't neutral drop to launch your car 4. No reason to put car in neutral at a stop 5. Don't put vehicle in park until car it is at a complete stop
0:28 Never put vehicle in neutral while coasting down the hill 2:35 When changing directions in an automatic vehicle, come to a stop before switching from drive -> reverse or reverse -> drive 4:03 Don't rev up in neutral and drop it into drive and let that carry your car forward (and various things you shouldn't do) 7:17 Don't put your car in neutral at a stoplight. Just leave it in drive 10:04 Don't put vehicle in park until you've come to a complete stop
they wont know but I suppose the compute might read shift lever positioning or whatever the call it. I know I live in AZ and know its illegal but I still do it sometimes, lol
Ashraf Raja I don’t see how losing acceleration causes an accident. In the case where somebody pulls out in front of you that is. You can still use your brakes. Why would it matter if you’re in neutral and get in an accident that couldn’t be avoided by accelerating? Maybe because if it is avoided you waste time going back into drive which increases risk of collisions for the people behind you who also have to stop? Like I understand not being able to get out of somewhere as quickly from being in neutral and that being the cause of the accident but what if the situation is somebody pulling out in front of you in that case you use your brakes but still hit them? The reason for hitting them isn’t because you’re in neutral as being in neutral won’t change the performance of slowing down.
Here's the simple version. 1. Don't put car in neutral down a hill [0:31]. 2. Make a complete stop before changing gears [2:35]. 3. Don't launch your vehicle at a high rpm spin/neutral switch [4:03]. 4. Don't put car in neutral at a stop light [7:15]. 5. Same thing as #2. Stop before you put it in park [10:05]. XD Hope this saves you guys time!
Extra: use the *Handbrake* when you park your car. Trust me, don't just stop and put the gear in P; It's better to stop, put it in Neutral, pull the Handbrake (then release the brake pedal), and then you put it in P (it will preserve your Transmission's lock that is active in the P position). Doing that you'll put all the car's weight into the Handbrake, not into the Transmission.
I prefer to let the car roll and settle into a low sweet spot in my driveway before putting it in park, gravity does nearly all the work keeping the car still. I still use handbrake on inclines. Using handbrake in freezing, foggy weather can be a bit troublesome though, I've had brake pads frozen to the surface of the brake rotor before
No joke. we live two blocks of gravel road away from the highway in town. I spend half a block getting up to 45-50mph (25mph speed limit), then put her in neutral, shut her off, pull of the key and put it in my pocket. Only use the brake to make it home.
Shifting to neutral at the stop is good for these reasons: 1. Prevents the torque converter from overheating. Idling in drive causes the impeller to rotate while the turbine is held stationary by the transmission which prevents the normal fluid flow inside the torque converter resulting in turbulence and heat generation by the fluid. 2. After a hard stop, shifting to neutral and releasing the brakes allows the brakes to cool down with the pads disengaged from the rotor which prevents the rotor warpage. 3. It will also circulate the fluid between the torque converter, the transmission, and heat exchanger further cooling down the torque converter.
One benefit of switching to neutral/park from drive is if your sitting still for an extended period of time (ie: drivethru, waiting on a train, etc). If stationary and in drive you are creating a lot of excessive heat in the torque convertor. A lot easier on it if you are in neutral or park.
I do it so I don't have to hold down the brake, just let my foot rest on the footboard, much more comfortable. He didn't give any good reason not to do it.
@@bnjmnalan Exactly! And yes, with the titular claim of Engineering Explained and warning of "Never," the reason for "never" is absolutely in order here.
"I can't think of any scenario to put it in Park while you're.moving." There's a story my Drivers' Ed teacher told us about a girl who thought "P" stood for Pass. She completely destroyed a transmission putting it in "Pass" at freeway speed.
Please tell me you're trolling. You'd destroy your transmission almost instantly. Not trying to be mean, but who taught you to drive? Like understanding "What these letters mean" is the first thing. Unless you're trolling, and if you are, well done
I had a friend when I was much younger do that EVERYTIME, drove me insane, then he would laugh at me when I was yelling at him, probably did it on purpose.
Have any of you people actually seen the working components of an automatic transmission, or at least understand how they function? Unlike a manual transmission, automatic transmissions are designed with something known as an Overriding Clutch in "Drive" mode. What this does, is it allows the vehicle to coast whenever the vehicle is moving faster than the engine is propelling it. Thus, when you lift your foot from the throttle, while approaching a traffic light, stop sign; or indeed, when you are rolling down a steep hill without your foot on the accellerator, your transmission is "automatically" coasting. So... in the interest of obeying all traffic laws, and for safety sake... Always keep your foot firmly planted on the gas pedal, while traversing intersectons and travelling down steep hills. The patriotic pride, and sense of satisfaction of knowing that you are obeying the rules of the road to the letter of the law, will more than offset the additional costs in fuel and incidental deaths. Not to mention the savings from tickets you avoid from the Coasting Police.
@NevRSweat WhatWas The free-wheeling clutch has nothing to do with the torque converter. In some cars, it's behind the gearbox, in others it's part of the transmission. In some cars (even automatics), it doesn't exist. In most cars, it's disabled if you've manually selected a lower gear.
I've been in several cars where I can feel the gears getting in the way of the momentum I've built with the gas (at lower speeds). This is only true if you're on the highway. Otherwise I'll coast in N to avoid the nausea lost fuel-economy gives me. Also, patriotism is for dull drones without personalities of their own.
I have a neighbor who routinely shifts from drive to reverse while still moving, and he honestly can't figure out why his transmission failed. Of course, listening to him, it's the truck's/dealer's/previous owner's fault. Go figure.
To me, this is like the same as doing this in a manual transmission vehicle, except for the fact that you can put it in reverse as long as you want but as long as you keep the clutch depressed, nothing bad will happen. I almost wrecked a 5-gear manual transmission once after driving a 6-gear transmission for a while, as I got so used to pull the stick back from 5 to 6. The Ford I was driving does NOT provide a security-feature like pulling a ring or pressing the stick down to get it in reverse... so yeah...
Reading the comments below I observe the following : 1) Manufacturers user manual is wasted money 2) People priced their life less than cost of saved fuel. 3) Many thinks they know more about car engineering than the maker of this video. 4) Many believe that their reasoning cannot be wrong. So interesting. Personal experience: as a manual car driver for most of my life and very used to cruising on neutral to the stop at traffic lights. I had to drive a automatic for few weeks and not knowing better, I did the same. Soon after, the gearbox went funny and dead. I was told later that by shifting gears from neutral to drive frequently causes more damage to the gearbox than leaving it engaged all the time. A painful lesson. I am not qualified to argue on engineering, but I had to agree fully with this video as this is what I experienced in my daily driving. Leaving the engine engaged as recommended by the manufacturer feels to me the right thing to do.
what kind of car did you drive? I didnt blow the tranny in my oldest car when I by accident pushed the gear shifter to park with an elbow. I was driving and reached the radio and bumped the shifter with my elbow, since ti was an old car it made a funky sound and my front tires locked up.. it shifted to drive ok after that.. not like it broke the tranny, also if you have small accidents like once a decade or somethign with things like that it shouldn't break the tranny, the gearbox etc.
I remember teaching a friend to drive my automatic Honda. He did everything perfectly, until I told him to stop the car. Puts it in Park at 15mph. Oh the grinding!!
what car was it ? at some point germans came up with antigrinder like in 1991 or something, once u are in motion u cant turn it to R or P untill u have come to stop
Definitely not made for it. Made to hold the vehicle in position, not made for the forces exerted on it by a moving vehicle. If it would ratchet, how would it hold your vehicle still when its parked nose-down?
One time I was parked on a very steep hill (facing down the hill), and accidentally put reverse instead of drive and let off the brakes. Oh man, that grinding noise. The engine stopped after a while, but disengaged the brakes' booster, so I was going down hill with minimal control, heading towards an intersection. When. I finally stopped (I didn't crash), the car wouldn't turn on for about 5 minutes. I thought I had fucked up my mom's SUV! When the engine turned on, the shifts weren't working properly and the engine sounded weird. I told my mom about the incident (as I thought we would've had to buy a new gearbox), but after four days the car returned to it's normal functioning. Up until now, I still don't know what happened or why it didn't get fucked up, but I'm glad it didn't.
I used to coast in neutral in my 94 'Civic 4 speed automatic. I was a student and I'm sure that saved fuel (modern cars do it now as well). I put older cars into neutral at lights sometimes, tends to make the car more quiet / transmit less vibrations.
For fuel economy, there is no question that coasting in neutral increases fuel economy. Fuel may be cut to the injectors in new cars, but the resistance of the engine will slow the car...meaning that you can cost in neutral on a slight decline and gain speed or maintain speed, where you will lose speed while the engine is engaged because of the engine resistance. In either case, anyone not actively engaged in driving shouldn't be driving. For states with ridiculous laws like this, I don't know how they explain manual transmissions being legal at all. For those who care, I've gotten as high as 27 mpg out of a 1997 Chevy Blazer, a lot of that was tire pressure, taking off the spare tire arm (and putting it in the back, yes, I do need a spare tire), other simple weight reduction, coasting in neutral, slower acceleration and avoiding braking (meaning, if you see a red light 300 yards up, don't accelerate into it just to stop, try to time your speed so you can still be rolling when the light is green). Accelerating from a dead stop is your biggest wasted fuel consumption.
funny, I do the opposite, I dont worry about removing crap from my truck, stil have spare tire, and all the crap holding it under the bed, etc. I do coast in N on hills, but I get 22-24 MPG when Im not caught up in traffic jams, my truck is rated by the EPA at 18-20 but the average was around 17 with what they measured, remember they use both city IE LA traffic patterns, and Highway coasting at 55or 65 MPH I can't remember which. RPM band has a lot to with it, I find I do better at gas mileage on the rural stretches of highway where I can cruise at 83. If I go faster it is too much RPM, If I go slower than that around 75 (the speed limit) it is at 4500 RPM in 4 th gear and not the OD. or so it seems. I watch my tach like a hawk. Also, I wont get speeding tickets on the interstate at 83. you get 10 mph here from DPS. (wouldnt recommend if you have out of state plates they will stop you at the speed limit even sometimes)
I will continue to use neutral on particular downhill stretches that result in not needing to press any pedal for protracted periods. It relieves my sciatic nerve pain as I rest my foot.
Just finished a month long course on auto trans and I can say there is a lot of great info in this video! Covers most of the basics that your average driver would need to know!
I'm curious about something, it was a bit of an argument that I got into, and I want a definitive answer to settle this. WILL/COULD/DOES shifting from drive to neutral and back cause any damage? Example: When trying to stop short, & u need the engine to detatch from drivetrain, b/c IDK, rev hang, whatever - FULL BRAKES, NO POWER is the idea, like how manuals can do. Does Neutral damage an auto trans?
@@aceof8S well on any newer vehicle with an eauto transmission that will not damage it at all. It may cause some issues if done in a very old automatic transmission that has more basic mechanical safety features on it. But it will always be faster to stop with the vehicle in gear because that way you will have mechanical engine braking helping stop the car. If it's in neutral you will be relying solely on the brakes to stop without helping from the engines resistance. Almost all cars nowadays have enough braking power to lock up all 4 wheels though so it won't necessarily make a big difference, it will just be a smoother slow down.
The level of professionalism coupled with simplycity by making a workshop inside your car with required components for the viedo makes me addicted for sure
+SciShow I used to say automatic transmissions functioned by red fluid and magic before I took an automatic transmission repair class. I still say that because I learned firsthand it was true.
one real good reason to put it in neutral while at a stoplight: if it's real hot and humid you can rev it up to 2000 rpms so the a/c gets real cold, ha ha
+mop10000 faster the compressor "does?" Do you mean, "faster the compressor and clutched fan spin, moving more cool air over the condenser and radiator allowing for a better experience inside the vehicle..?"
Most of the "stresses" you mention are absorbed by the ATF. You should advise that if you perform "launches" often then you should change your Transmission Fluid more often as this will help with longevity. ATF is complicated, the hotter it gets the faster it degrades, but if you keep the temps in check there isn't much to worry about. auxiliary coolers help...
lol, I did it the first time I bought a car with automatic transmission, quickly realized I shoudn't put in neutral when driving even if it would wear something because it's unsafe, and then I come here to know if it would really wear things, but no.
Thinking it might be because of how long it takes for him to arrive at very basic concepts. I mean this video could have been less than 5 minutes and conveyed just as much worthwhile info. Was pretty frustrating hearing him drone on and on, but none of this was new to me...
Moe K Idk what kind of metaphor that was but tbh I was not even talking to you. I was talking to .. Didn't have much of a choice... . I clicked on his reply's "reply" button but his name didn't get tagged.
My grandma cuts the mango in half and dice them like checkerboards with the skin still on it. then you push the middle outward so you can get the good stuff.
But can you go from neutral to drive whilst coasting (not pressing the accelerator) like normally in a manual car? Or will it make the same noises? Lol
Mine sounded like a helicopter when I accidentally applied power before my transmission could fully engage, I had to take it out of gear and put it back in and it's fine now
1.Never coast downhill in neutral: Modern automatic transmissions cut fuel to the engine on their own, so putting your car in neutral won’t save you any gas. Also, it takes some control away from you and it’s illegal in 15 states (full list at the link below). 2.Never switch directions without stopping: Make sure you come to a complete stop before going from drive to reverse or vice versa. Otherwise, you’re using your transmission to stop the vehicle instead of letting your brakes do their job. 3.Never “launch” your vehicle: Don’t rev your car’s engine in neutral and drop into drive to launch yourself forward. It’s fast way to wear out the bands in your transmission (they’re expensive to replace). 4.Never put your car in neutral at a stop light: It won't save you any fuel (fractions of a gallon if any), and it can wear on the transmission. 5.Never shift into park until you’ve come to a complete stop: Some cars won’t even let you do this, but you should never do it anyway. You can damage or break the locking pin that’s used to keep your transmission from running.
Owner's manuals for late 60's - early 70's Chrysler products actually advised putting automatic transmissions in neutral while not moving, but designs have changed since then.
My personal reason for putting it in neutral at a stoplight was not mentioned. Preferring a manual transmission, the automatic transmission idle creep drives me crazy.... I can't stand mashing the break for long traffic lights.
Thanks Corin, thats the main reason i know to put it in neutral in a traffic jam or at a stop light. Also if you happen to let some of your pressure off the brake pedal the car can still creep forward and you might not even know it. Easier just to put car in neutral.
????? okay....but if you put the car in park you don't have to hold the brake and the car work creep forward while your talking on the phone and roll into the car n front of you......or replying to me ...andif you forget what gear youre in while on a hill because youre saving SO much fuel you wont roll into other people... safety first lol
I shift to neutral at a stop light because it makes my car idle more smoothly. My car really wants to move when I switch to drive, even though the idle speed is not too high, so I figure I save some gas too. I heard somewhere that switching to neutral will also keep your engine cooler.
i wonder about this a lot. i drive an AT from 2002 so I wonder if a lot of these videos assume the viewer is driving something atleast from 2011 onwards
+silicon212 Used to do that when I had my first car, If i was at a drive through with a long line I would shift it to neutral lol But now most of my cars are standards, so I don't have to worry about that as much lol
The laws concerning coasting down hill in neutral are directed towards heavy trucks, not your car or pickup (unless you're pulling a trailer). In a truck such as a semi, you need all of the braking assistance you can get, especially going down hill. We truck drivers actually call "coasting" Georgia overdrive. As for what you kids call "launching" today, old guys like me call it a neutral drop or neutral slam. I don't know about these days, but, it used to be that the only people who did it were those that didn't have a car/truck that could burn the tires while in gear from a stop. It causes all kinds of damage. I've seen everything from broken drive shafts to cracked trans cases.
It's common sense: when you are stopped in drive, the ECU will try to reach the same rpm level in both situations, but it has a limit on the fuel it can give in idle. The result is that in neutral it will usually be consuming half of the fuel it does on drive. That changes with the start&stop function, but even that has some limits, since starting the engine will use a lot more fuel than a 10 seconds idle time would. The conclusion is: always put the car in neutral on stops if you dont have start&stop (turn it off if you are at a closed railway), if you do have start&stop, estimate if it a reasonable timed stop (then let the car turn off) or if it is just a quick stop (then put it in neutral, since the function usually only works in drive). Drive safely!
@@oldjarhead386 Automatic cars have a torque converter spinning and causing drag when in drive and being stopped. This is just a fact. If you put the car in neutral, you'll consume way less. Start and stops become convenient for medium to long stops.
my friends and I broke 2 engine mounts in a Toyota Camry by redlining the engine and then slamming the transmission into drive...but it did do a great burnout! :)
This is very basic, some of these abuses of the "slush-pump" horrify me...in our teens we abused many Powerglides and learned the hard way, although they were amazingly tough...excellent explanations from Jason as usual.
Also wondering how you're "giving up control" if you coast. If you need to speed up, you can put it back to drive. No one said they're switching to N and ripping off the selector...
They utilize Mobile Waterboarding Units to coax a confession out of innocent motorists. Never admit to terroristic neutral coasting on public roadways! (Always carry fresh jelly donuts, for use as a roadside bargaining tool. Any crime can be overlooked, when a jelly donut is offered.)
First, slice along the pit, both sides; second, cut a cross hatch pattern into the flesh; third, bend the skin back away from the flesh; fourth, bite each cube of flesh off the skin.
Torque converter is always full of transmission fluid and rotates as one assembly, not in separate halfs like you showed. The turbine can sometime rotate separately from the housing, but mostly it's the stator in the middle that does the "power transfer". People in the know knows this, but not everybody and it might confuse them. Also, hold the brake and accelerating at the same time causes what is called "Converter stall" when impeller from the engine is supplying all the torque, but the turbine on the trans end cannot move. If held for more than 2 minutes, the torque converter can overheat.
As a new driver, I am glad I knew not to do any of this. Granted, without real reasoning. Also, the tip about launching was really helpful too. Again, even though I sort-of already had figured it out. It's really nice to have someone who knows what their talking about reinforce the knowledge you already had.
@@pokwerpokwerpokwer would you rather die than doing something illegal, its illegal to drive over the speed limit too, I bet you have done that sometimes
Been driving manual cars for years and got my first automatic so interesting info here. Guess I have not done anything you're not supposed to do but it's about time to try and launch it in a proper way 😁
IF you should get in an accident that might have been avoided except you had no control of the car because you were rolling it instead of driving it ... then you might not only have the accident but also find out you are the liable party, because you were violating the law at the time. ?? Anyway, since you can react faster if you don't have to shift out of neutral into gear, why coast?
When sitting in drive at a stop light and the engine rpms are lower, the engine also gets a richer air-fuel-mixture for it not to stall. So the difference in fuel economy should only be the amount that the torque converter heats up over time by being spun at the one end but being blocked to spin at the other.
There is a very good reason to shift into neutral at a stoplight, but neither stress on the transmission nor fuel savings is it. The reason is to avoid moving forward (into the back of the vehicle in front of you or, far worse, into cross traffic) if your foot slips off the brake. This could occur because of simple slipperiness or distraction - the dog or the kids or whatever.
Agree, adding the fact that if you've been driving for a long time, and a stop-light that lasts for more than 3 minutes is quite tiring, may even result for you to let loose the breaks and slowly move the car forward. That's why "Never put your gear on Neutral on stop-light" is quite strong, probably better "There's no need to put your gear on Neutral on stop-light sign" would be precise. I also cannot hear him say anything that could damage the car in doing this. My rule is always been, if the traffic lights is 3 mins+ before it go, then I set it to Neutral + Hand break (just making sure I don't mistakenly move the vehicle).
As someone who learned on a manual transmission it always feels like neutral is calm when stopped. Automatic feels like the engine is fighting the brakes. Waiting in the drive thru fast food line my car is asking me to please disengage. It seems like not shifting to neutral or park is like riding the clutch. There must be friction somewhere. This explains why some don't trust automatic for towing as there is never a complete metal to metal lock up. Great job on all of your tech break downs.
I did that in my civic it locked the steeringwheel and ignition switch. I pulled the Ebrake and the brakes and was able to stop easily. lol not a good idea if you need to turn
@Connor Ok but modern brakes have vacuum assist (so you can brake with a light tap) that doesn't work when the engine is off. Don't do it in a modern car.
@@user-njyzcip There's enough vacuum when you shut down the engine for a good stop, you'd have to intentionally force it out (you'd need to pump the brakes; just holding the pedal down won't just run out of assist)
Sure, my car cuts off the fuel to the engine when going down a hill in gear - but this causes the engine to induce drag through the drive train, requiring me to accelerate up the next hill rather than coasting over it. I contend that I use more energy accelerating up a hill than I save going down one in gear. I don't buy your argument and, unless coasting actually damages the transmission, I'll continue doing it.

If you shift to neutral and then have to apply the brakes you're wasting energy: engine consuming gas to keep idling + brakes throwing away kinetic energy as heat. The induced drag you feel coasting in gear is the amount of energy it takes to rotate the engine, yes it's noticeable which is why idling wastes gas! To minimize drag you can upshift to keep RPMs just above the normal idle speed of the vehicle.
I was once on the high way in my parents 2000 Toyota sienna, and I bumped the Transmission into reverse at 100 kph. big bang and the engine stalled, but started right up and has been driving since with no issues what so ever haha.
When I park my car, like at an incline i always put it Neutral then pull the handbrake, release the brake pedal, making sure it rests on the pads and then put it in P. Its just feels better to know the whole weight of the car rests on the handbrake and not on the '' locking pin '' =)
Do not turn you car off frequently at red lights you might save gas but you will wear out your starter. Starters are not ment to handle continuous turning on. They have to move a lot of weight to move pistons and flywheels that's why they use a lot of amperage. BMW found a way to put less stress to starters in their new vehicles that turn off and on at red lights. Regular engines cannot do that without putting unnecessary wear on a starter.
Light hybrid actually stop the engine and restart when you step on the accelerator. The starter is bigger and belt driven, not geared through the flywheel. Some trucks get 20% better MPG using this.
Raymond Ramírez no starter is belt driven, you can not put enough Torque on a regular belt to crank a engine over. You must be thing of a alternator that is belt driven. Some cars have smart tech that can fire the engine up without the starter, it use the crank sensor to find out what pistons is at TDC and it injects fuel and fires the spark plug to crank it over. Car's with start /stop tech have bigger/stronger starter some are even geared so it's less stress on the motor. The alternator and battery are also larger to cope with the number of starts
Fernando Ramirez pretty sure your starter motor has a shitload of tolerance in it If it doesnt, send it back for replacement under warranty Most new cars have stop start technology anyway im.pretty sure theyve tested that before they decided to make it a selling point
Satveer Degun there is NO tech to start a car with just firing, that is the dumbest comment I've ever heard. There are continuous duty starters out there made for this
Trivial safety tip from an ex-driver. If you're at a set of lights, it is good practice to learn to apply the emergency/park/hand brake. Why? The forces applied to your body (and sometime the surprise) if you get rear-ended will pull your foot off the brake, causing your vehicle to ricochet forward, sometimes clear across the road or possibly into cross traffic. Having the handbrake applied mitigates that lurch forward and may prevent a more serious situation. Just remember to release the emergency/park/hand brake when the lights go green.
yeah, i always try to put it in neutral and only tend to apply the handbrake if i think i’m gonna be staying there a while, but i try to keep my foot on the brake until there’s someone stopped behind me as well
So, AXLEGREASEframeset, AUTOMATIC transmissions are weak as hell and are designed for pussies! You need a MANUAL transmission. They are strong and are for people who can actually drive. When going downhill, put it "R" (for "Really slow"). HACK: double clutch to do this. No need to than me, bro. Just post a vid showing how this works. SM
Senor Mofeta BRO, you're such a scrub. R is Race Mode. You shift into it once you get past 5th gear. My nonexistent little brother knows that. ...if he existed, that is. In that case he'd be all like 'duh'.
+Josh Williams Well, you have a tank of highly volatile and explosive liquid, and a chunk of steel that makes on average about 100,000 watts of power and 300,000 watts of heat, that's a lot of energy to tame...
+Josh Williams As an ex mechanic, you're not the only one. Believe me. I've got more stories than i can remember fully about what people do to their cars. But mostly, cars can really take a lot of abuse without breaking. Just don't expect it to last as long as it would have otherwise, and expect the repair bill to be expensive.
+Josh Williams Yes. If a lever moves at the wrong time it breaks a car. That's why cars are stupid - lever should not move at the wrong time if someone tries it at the wrong time. This start by button is also stupid - I wanted to turn off a radio and I turned off an engine, at least I wasn't moving too fast.
Excellent video! I am guilty of shifting into neutral for a long coasts to gain maximum fuel economy. Never considered that the engine stops sending fuel in a coast! However, I know it causes great drag in drive. Brilliant video! Thanks.
someone who drives manual always and then the odd time drives auto, i always put my manual into 1st while moving coming to a stop and pull the ebrake to stop completely since i use it anyways. so going into an auto its just habit to go the direction of 1st which happens to also be the direction of park
Thanks for the effort you put in on this video. I’m uk and not everyone would understand this let alone understand a manual car. Automatic transmissions are a thing of beauty these days and should be understood. Tough to get a lux car without one and in uk a lot of drivers don’t get the transition or nuances. Great video and top effort.
He's right about unnecessary shifting into neutral while on steep decline. The vehicle compensates for the angle of decline as he stated in his video. My truck downshifts my transmission, I slow down and my MPG indicates that I'm gaining in MPG. the process is not without a real sense of "jerky-jerkiness" as the truck begins to ascend on the next hill, it takes a second or more to reconfigure the shift algorithm and then find the gear while it begins to accelerate almost simultaneously. It's not perfect but I let it do its designated job. I've encountered this countless times in my '12 Tundra and I understand it was programmed for fuel economy and liability. The only time I shift into neutral is when i'm on a level road and approaching a stop light/sign and I wish to save my brakes unnecessary heat during hot, summer months. My truck won't be surging against my brakes and my rotors can cool off.
Georgia Fan of course it doesn't mean you have to do it on every hill if it's up and down, only when it's downhill to a stop or red light just like you're doing on the level so you can shift to D from a stop or slow roll. Also for breaks I've made mine last long by 'tapping' them for a couple seconds until I'm down to around 30-40 mph and then fully stopping from there. I drive a 4x4 with a v8 so the vehicles pretty heavy and I've found that to work
I experienced a situation where coasting in neutral saved the day! Driving Out of the mountains, down hill, on I-70 into Denver on a snow-covered (with ice) road in a front wheel drive mini-van. I was doing around 30 mph, but when I let off the gas, the speedometer read 10 mph - in other words the front tires had no traction, no capability to steer. I put the van in neutral (several miles) and pumped the brakes until the van slowed, and could return to normal driving. Very scary at 3:00 AM!! Made it back to Chicago later that day.
I’m amazed how strong brakes can be. Whether peeling out in a car or launching a jet. The Blue Angels can demonstrate to passengers how it feels to be launched from an aircraft carrier. The pilot locks the brake, raises the engine thrust, then releases the brake for instantaneous acceleration.
Brakes will stop any engine. That information should have been given to folks who fear "unintended acceleration." If your engine does over-revs in gear, the brakes - even on the worst car - will stop it. My revivifier had a Fiero that demons would possess periodically, but the old-fashioned, crappy brakes could stop it.
Dragging engines down hills chills them from the continuous high vacuum at elevated RPM. Fast thermal cycling is hard on parts. I drive MT and use neutral (with some revs for fluid circulation) or at least top gear for extended downhill. Lack of control? Illegal? Not a concern. The few AT’s I’ve owned didn’t exhibit issues with using neutral down hills or at lights. I agree tho on neutral drops to launch: no bueno. Sitting in drive wastes fuel and drags on engine internals while there’s relatively low oil pressure/circulation and poor sling off the crank. 2k rpm is engine break in speed for this reason. Bogging an engine below 2k while driving is even worse. Not being contrarian I just disagree based on theory and experience. Great vid nonetheless thanks for posting and especially the casual torque converter 👍
A thousand years ago, when I was in college, I would regularly borrow a friend's 1972 Satellite Sebring which had a really cool (for the time) floor mounted shifter. One night whilst playing Speed Racer with his car, I accidentally shifted from Drive into Reverse at about 40 mph. There was a loud noise, the engine stalled, and the car came to a sudden stop. I restarted the car and drove home without incident. I didn't mention what I had done and about five of us drove the car on a regular basis for the remaining seven months of the school year without a transmission problem. At the end of the school year, he graduated and bought a brand new car. I finally told him about the incident about twenty years later. I don't recommend this as a regular practice but offer this story as an example of how old cars were built to take abuse.
Gold Winger If after the incident the car drove without issue for the next 7 months, why did you wait 20 years to tell your friend what happened? 🤔 So, if you slept with your friend's wife, maybe you would write your confession on a piece of paper, putting said confession in a glass bottle, then throwing it out to sea to be found and read 70 years later 😉
@@user2144 Simple, I didn't know if the transmission was unscathed from my faux pas or if it was living on borrowed time. As for the second question, having sex with his wife lacks the potential for causing her permanent harm and there is no humerous context in which you can say, "Dude, I banged your wife!"
Thank you for the explanation on the shifting from drive to reverse and vise versa. I tend to do this to not take long when trying to get out of a parking spot or stuck in a tight area. Did not know about that band being in danger and hard to access, Ima do complete stops now before shifting. Thanks man I'm the type who likes to take care of things and make them last long but it's a bad habit I picked up from my pops and didn't know it was possibly doing harm.
Things you can do in a manual without having to worry: Coaster in neutral. Wait at stop lights in neutral. Launching is still eh but a little less oof.
This is awesome, I did a lot of other research myself on how stuff works which was a blast but here I am learning so much practical knowledge on what I originally thought was just myth and not that big of a deal. This is what I originally thought would make the internet so amazing, knowledge like this at the click of a finger! Thanks for doing these, amazing!
For #4, a reason to put it in park at a stop light is so that if you get rear ended and incapacitated, and your foot comes off the brake, the car doesn't keep inching forward into traffic. For #5, yes, some cars will allow you to throw it into park while moving, at least at low speeds. I was driving my wife's Chrysler 200 on a road trip and accidentally flipped it into park as I was coming to a stop in a parking lot. I usually drive a manual and popping the car into neutral while I come to a stop is an ingrained behavior, which is why it happened. The car was going slow enough not to cause damage, but I definitely felt that pin engage.
#1 Don't coast down a hill in neutral because you want to use your transmission to slow your car.#2 Always be stopped before shifting in reverse because you don't want to use your transmission to slow your car.Got it.
You twice referred to “saving fuel economy”, and I believe “saving fuel, or gaining fuel economy” is the correct way to say it. Good information; thanks.
Fuel economy is calculated by mileage covered and gallons used per minute and engine demand. So your car will give you the wrong estimate if your car is in neutral at a stop, but engine load is reduced a lot if you're in neutral, then if you're in drive. In drive at a stop, the demand is slightly more to keep the engine running at an acceptable RPM so the engine can idle under load from the transmission. Think of it as a bodybuilder holding his arm straight out with a 20lb weight for 15 minutes, as opposed to holding his arm straight out for 15 minutes with no weight.
Modern automatic transmissions will disengage the clutches and brake bands by themselfes when the vehicle is not moving and the brakes are applied. Thats basically the exact same thing as when the driver puts the transmission in neutral. As soon as you lift your foot off the brake pedal the transmission engages the first gear and you are good to go
Uh no. An engine uses less gas at a lower speed than at a higher speed, regardless of load. If it used less gas at a lower load it would risk predetonation. In either case, you're getting 0mpg for that duration, but having the engine burn extra gas while at a stop would decrease the average fuel economy by increasing the total number of gallons burned for the same amount of distance travelled.

Hard time, brah.
Ashraf Raja I don’t see how losing acceleration causes an accident. In the case where somebody pulls out in front of you that is. You can still use your brakes. Why would it matter if you’re in neutral and get in an accident that couldn’t be avoided by accelerating? Maybe because if it is avoided you waste time going back into drive which increases risk of collisions for the people behind you who also have to stop? Like I understand not being able to get out of somewhere as quickly from being in neutral and that being the cause of the accident but what if the situation is somebody pulling out in front of you in that case you use your brakes but still hit them? The reason for hitting them isn’t because you’re in neutral as being in neutral won’t change the performance of slowing down.
I like to slam it in 1st then 2nd to slow from 60 mph. Sometimes I will even drop to reverse for the cool sound it makes.

So no reverse lockout when shifting it from fwd to rev, is that a vintage slush box or did you take out reverse?

Extra: use the *Handbrake* when you park your car. Trust me, don't just stop and put the gear in P;
It's better to stop, put it in Neutral, pull the Handbrake (then release the brake pedal), and then you put it in P (it will preserve your Transmission's lock that is active in the P position).
Doing that you'll put all the car's weight into the Handbrake, not into the Transmission.
Had a friend that his handbrake was failing amd his trans would get stuck in park. We would have to rock the car back and forth to get it out.
I prefer to let the car roll and settle into a low sweet spot in my driveway before putting it in park, gravity does nearly all the work keeping the car still. I still use handbrake on inclines. Using handbrake in freezing, foggy weather can be a bit troublesome though, I've had brake pads frozen to the surface of the brake rotor before
I always do that out of habit from driving my manual cars lol. I was always taught that the parking prawl is just an emergency backup.
I just keep the brake pedal pressed in as I put it in park and then I pull the handbrake before releasing the pedal.
If you park on a driveway with a slight grade its highly encouraged
I like to put my car in neutral down a hill and pull the keys out.

No joke. we live two blocks of gravel road away from the highway in town. I spend half a block getting up to 45-50mph (25mph speed limit), then put her in neutral, shut her off, pull of the key and put it in my pocket. Only use the brake to make it home.

We don't like your kind around here.
Shifting to neutral at the stop is good for these reasons:
1. Prevents the torque converter from overheating. Idling in drive causes the impeller to rotate while the turbine is held stationary by the transmission which prevents the normal fluid flow inside the torque converter resulting in turbulence and heat generation by the fluid.
2. After a hard stop, shifting to neutral and releasing the brakes allows the brakes to cool down with the pads disengaged from the rotor which prevents the rotor warpage.
3. It will also circulate the fluid between the torque converter, the transmission, and heat exchanger further cooling down the torque converter.
but what about the guy who crashes into you because your brake light is not on and is reading text on their phone LOL
i was looking for that. i wonder why he didn´t include this
I just push my car down a hill while in neutral quickly jump in and hope I build enough speed to get me home.

One benefit of switching to neutral/park from drive is if your sitting still for an extended period of time (ie: drivethru, waiting on a train, etc). If stationary and in drive you are creating a lot of excessive heat in the torque convertor. A lot easier on it if you are in neutral or park.
Exactly.
It's a habit I picked up because I learned to drive from a manual transmission. Doesn't seem to hurt the auto transmission we have so I do it.
I do it so I don't have to hold down the brake, just let my foot rest on the footboard, much more comfortable. He didn't give any good reason not to do it.

Have any of you people actually seen the working components of an automatic transmission, or at least understand how they function?
Unlike a manual transmission, automatic transmissions are designed with something known as an Overriding Clutch in "Drive" mode.
What this does, is it allows the vehicle to coast whenever the vehicle is moving faster than the engine is propelling it. Thus, when you lift your foot from the throttle, while approaching a traffic light, stop sign; or indeed, when you are rolling down a steep hill without your foot on the accellerator, your transmission is "automatically" coasting.
So... in the interest of obeying all traffic laws, and for safety sake...
Always keep your foot firmly planted on the gas pedal, while traversing intersectons and travelling down steep hills. The patriotic pride, and sense of satisfaction of knowing that you are obeying the rules of the road to the letter of the law, will more than offset the additional costs in fuel and incidental deaths.
Not to mention the savings from tickets you avoid from the Coasting Police.
@lRaziel1 no! it will go the same speed. "the vehicle will coast whenever the vehicle is moving faster than the engine is propelling it"
Priceless.!
YES MOMMY!
@NevRSweat WhatWas The free-wheeling clutch has nothing to do with the torque converter. In some cars, it's behind the gearbox, in others it's part of the transmission. In some cars (even automatics), it doesn't exist. In most cars, it's disabled if you've manually selected a lower gear.
I've been in several cars where I can feel the gears getting in the way of the momentum I've built with the gas (at lower speeds). This is only true if you're on the highway. Otherwise I'll coast in N to avoid the nausea lost fuel-economy gives me. Also, patriotism is for dull drones without personalities of their own.

I have a neighbor who routinely shifts from drive to reverse while still moving, and he honestly can't figure out why his transmission failed. Of course, listening to him, it's the truck's/dealer's/previous owner's fault. Go figure.
Tina Gallagher, lol 😁
Some people just can't be told, huh! lol 😁
Tina Gallagher I do this a lot, is it really that bad?
I would just look on and laugh
To me, this is like the same as doing this in a manual transmission vehicle, except for the fact that you can put it in reverse as long as you want but as long as you keep the clutch depressed, nothing bad will happen.
I almost wrecked a 5-gear manual transmission once after driving a 6-gear transmission for a while, as I got so used to pull the stick back from 5 to 6. The Ford I was driving does NOT provide a security-feature like pulling a ring or pressing the stick down to get it in reverse... so yeah...
I’m not in denial my car is in shop getting a transmission rebuild for doing this same thing lesson very well learned
Reading the comments below I observe the following : 1) Manufacturers user manual is wasted money 2) People priced their life less than cost of saved fuel. 3) Many thinks they know more about car engineering than the maker of this video. 4) Many believe that their reasoning cannot be wrong. So interesting. Personal experience: as a manual car driver for most of my life and very used to cruising on neutral to the stop at traffic lights. I had to drive a automatic for few weeks and not knowing better, I did the same. Soon after, the gearbox went funny and dead. I was told later that by shifting gears from neutral to drive frequently causes more damage to the gearbox than leaving it engaged all the time. A painful lesson. I am not qualified to argue on engineering, but I had to agree fully with this video as this is what I experienced in my daily driving. Leaving the engine engaged as recommended by the manufacturer feels to me the right thing to do.
Great comment, covers it all. :D
what kind of car did you drive? I didnt blow the tranny in my oldest car when I by accident pushed the gear shifter to park with an elbow. I was driving and reached the radio and bumped the shifter with my elbow, since ti was an old car it made a funky sound and my front tires locked up.. it shifted to drive ok after that.. not like it broke the tranny, also if you have small accidents like once a decade or somethign with things like that it shouldn't break the tranny, the gearbox etc.
You probably destroyed your drum band which changes the gears
This was an expensive mistake for me as well while a teenager... save a few pennies on fuel (I thought), expense transmission repair instead.
Why would you ever coast in neutral in a manual. Just enginebreak
I remember teaching a friend to drive my automatic Honda. He did everything perfectly, until I told him to stop the car. Puts it in Park at 15mph. Oh the grinding!!
what car was it ? at some point germans came up with antigrinder like in 1991 or something, once u are in motion u cant turn it to R or P untill u have come to stop
It's the pawl ratcheting. It's designed to do it.
+sugahotcakes not from 15 lol
Definitely not made for it. Made to hold the vehicle in position, not made for the forces exerted on it by a moving vehicle. If it would ratchet, how would it hold your vehicle still when its parked nose-down?
One time I was parked on a very steep hill (facing down the hill), and accidentally put reverse instead of drive and let off the brakes. Oh man, that grinding noise. The engine stopped after a while, but disengaged the brakes' booster, so I was going down hill with minimal control, heading towards an intersection. When. I finally stopped (I didn't crash), the car wouldn't turn on for about 5 minutes. I thought I had fucked up my mom's SUV! When the engine turned on, the shifts weren't working properly and the engine sounded weird. I told my mom about the incident (as I thought we would've had to buy a new gearbox), but after four days the car returned to it's normal functioning. Up until now, I still don't know what happened or why it didn't get fucked up, but I'm glad it didn't.
I used to coast in neutral in my 94 'Civic 4 speed automatic. I was a student and I'm sure that saved fuel (modern cars do it now as well).
I put older cars into neutral at lights sometimes, tends to make the car more quiet / transmit less vibrations.
yup I always put my car in neutral at stoplights bc it vibrates like crazy at idle (Ford ZX2)
For fuel economy, there is no question that coasting in neutral increases fuel economy. Fuel may be cut to the injectors in new cars, but the resistance of the engine will slow the car...meaning that you can cost in neutral on a slight decline and gain speed or maintain speed, where you will lose speed while the engine is engaged because of the engine resistance. In either case, anyone not actively engaged in driving shouldn't be driving. For states with ridiculous laws like this, I don't know how they explain manual transmissions being legal at all. For those who care, I've gotten as high as 27 mpg out of a 1997 Chevy Blazer, a lot of that was tire pressure, taking off the spare tire arm (and putting it in the back, yes, I do need a spare tire), other simple weight reduction, coasting in neutral, slower acceleration and avoiding braking (meaning, if you see a red light 300 yards up, don't accelerate into it just to stop, try to time your speed so you can still be rolling when the light is green). Accelerating from a dead stop is your biggest wasted fuel consumption.
funny, I do the opposite, I dont worry about removing crap from my truck, stil have spare tire, and all the crap holding it under the bed, etc. I do coast in N on hills, but I get 22-24 MPG when Im not caught up in traffic jams, my truck is rated by the EPA at 18-20 but the average was around 17 with what they measured, remember they use both city IE LA traffic patterns, and Highway coasting at 55or 65 MPH I can't remember which. RPM band has a lot to with it, I find I do better at gas mileage on the rural stretches of highway where I can cruise at 83. If I go faster it is too much RPM, If I go slower than that around 75 (the speed limit) it is at 4500 RPM in 4 th gear and not the OD. or so it seems. I watch my tach like a hawk. Also, I wont get speeding tickets on the interstate at 83. you get 10 mph here from DPS. (wouldnt recommend if you have out of state plates they will stop you at the speed limit even sometimes)
I will continue to use neutral on particular downhill stretches that result in not needing to press any pedal for protracted periods. It relieves my sciatic nerve pain as I rest my foot.
This video taught me so much about mangos, thank you very much.
Just finished a month long course on auto trans and I can say there is a lot of great info in this video! Covers most of the basics that your average driver would need to know!
I'm curious about something, it was a bit of an argument that I got into, and I want a definitive answer to settle this.
WILL/COULD/DOES shifting from drive to neutral and back cause any damage?
Example: When trying to stop short, & u need the engine to detatch from drivetrain, b/c IDK, rev hang, whatever - FULL BRAKES, NO POWER is the idea, like how manuals can do.
Does Neutral damage an auto trans?
@@aceof8S well on any newer vehicle with an eauto transmission that will not damage it at all. It may cause some issues if done in a very old automatic transmission that has more basic mechanical safety features on it.
But it will always be faster to stop with the vehicle in gear because that way you will have mechanical engine braking helping stop the car. If it's in neutral you will be relying solely on the brakes to stop without helping from the engines resistance. Almost all cars nowadays have enough braking power to lock up all 4 wheels though so it won't necessarily make a big difference, it will just be a smoother slow down.
The level of professionalism coupled with simplycity by making a workshop inside your car with required components for the viedo makes me addicted for sure

one real good reason to put it in neutral while at a stoplight: if it's real hot and humid you can rev it up to 2000 rpms so the a/c gets real cold, ha ha
I do that too haha
But doesn't that take away power from the A/C to rev up the engine?
The A/C compressor is connected to the engine via a pulley. The faster the engine spins the faster the compressor does.
+mop10000 faster the compressor "does?" Do you mean, "faster the compressor and clutched fan spin, moving more cool air over the condenser and radiator allowing for a better experience inside the vehicle..?"
mop10000 Interesting. Good to know.
Most of the "stresses" you mention are absorbed by the ATF. You should advise that if you perform "launches" often then you should change your Transmission Fluid more often as this will help with longevity. ATF is complicated, the hotter it gets the faster it degrades, but if you keep the temps in check there isn't much to worry about. auxiliary coolers help...
the worst thing about coasting in neutral is when you forget and go to accelerate

1.Never coast downhill in neutral: Modern automatic transmissions cut fuel to the engine on their own, so putting your car in neutral won’t save you any gas. Also, it takes some control away from you and it’s illegal in 15 states (full list at the link below).
2.Never switch directions without stopping: Make sure you come to a complete stop before going from drive to reverse or vice versa. Otherwise, you’re using your transmission to stop the vehicle instead of letting your brakes do their job.
3.Never “launch” your vehicle: Don’t rev your car’s engine in neutral and drop into drive to launch yourself forward. It’s fast way to wear out the bands in your transmission (they’re expensive to replace).
4.Never put your car in neutral at a stop light: It won't save you any fuel (fractions of a gallon if any), and it can wear on the transmission.
5.Never shift into park until you’ve come to a complete stop: Some cars won’t even let you do this, but you should never do it anyway. You can damage or break the locking pin that’s used to keep your transmission from running.
Owner's manuals for late 60's - early 70's Chrysler products actually advised putting automatic transmissions in neutral while not moving, but designs have changed since then.
My personal reason for putting it in neutral at a stoplight was not mentioned. Preferring a manual transmission, the automatic transmission idle creep drives me crazy.... I can't stand mashing the break for long traffic lights.
Thanks Corin, thats the main reason i know to put it in neutral in a traffic jam or at a stop light. Also if you happen to let some of your pressure off the brake pedal the car can still creep forward and you might not even know it. Easier just to put car in neutral.
so why not put it in park and when the light turns green put your foot on the brake and shift to drive .... all bases covered
Harry Aiken because you hit reverse first and it's three notches before drive instead of one! more delay going from park to drive!
????? okay....but if you put the car in park you don't have to hold the brake and the car work creep forward while your talking on the phone and roll into the car n front of you......or replying to me ...andif you forget what gear youre in while on a hill because youre saving SO much fuel you wont roll into other people... safety first lol
no brake lights at an intersection? what kind of backwards ass pagentry is that?
I shift to neutral at a stop light because it makes my car idle more smoothly. My car really wants to move when I switch to drive, even though the idle speed is not too high, so I figure I save some gas too. I heard somewhere that switching to neutral will also keep your engine cooler.
Only applies to older vehicles with less advanced autos and electric cooling fans
i wonder about this a lot. i drive an AT from 2002 so I wonder if a lot of these videos assume the viewer is driving something atleast from 2011 onwards
Definitely you don't watch the video fully or you understand it..
The only reason why I would put my car in neutral at a light is because it's a long light and I don't want to keep my foot on the brake :/
Same
I just put the handbrake on in drive +silicon212

Well that's good for you and your Sonata - not so much with my Crown Vic P71.

The laws concerning coasting down hill in neutral are directed towards heavy trucks, not your car or pickup (unless you're pulling a trailer). In a truck such as a semi, you need all of the braking assistance you can get, especially going down hill. We truck drivers actually call "coasting" Georgia overdrive. As for what you kids call "launching" today, old guys like me call it a neutral drop or neutral slam. I don't know about these days, but, it used to be that the only people who did it were those that didn't have a car/truck that could burn the tires while in gear from a stop. It causes all kinds of damage. I've seen everything from broken drive shafts to cracked trans cases.
Also because cars had crap brakes in the old days.
It's common sense: when you are stopped in drive, the ECU will try to reach the same rpm level in both situations, but it has a limit on the fuel it can give in idle. The result is that in neutral it will usually be consuming half of the fuel it does on drive. That changes with the start&stop function, but even that has some limits, since starting the engine will use a lot more fuel than a 10 seconds idle time would. The conclusion is: always put the car in neutral on stops if you dont have start&stop (turn it off if you are at a closed railway), if you do have start&stop, estimate if it a reasonable timed stop (then let the car turn off) or if it is just a quick stop (then put it in neutral, since the function usually only works in drive). Drive safely!
That is not even close to how an ECU controls the engine. Where did you get that?
@@oldjarhead386 Automatic cars have a torque converter spinning and causing drag when in drive and being stopped. This is just a fact. If you put the car in neutral, you'll consume way less. Start and stops become convenient for medium to long stops.
I do all these on the daily

Better start saving up
my friends and I broke 2 engine mounts in a Toyota Camry by redlining the engine and then slamming the transmission into drive...but it did do a great burnout! :)
A lot of modern transmissions will automatically shift into neutral when you come to a stop in order to save fuel
Are they shifting to neutral or simply using an auto-start/stop system to disengage the engine?
P. No this is before stop/start. Cars like the 2002 Opal (Holden) Astra will select neutral when you stop. you can't even tell the car is doing it.
John O Interesting. Thanks.
When I was 15 I broke my friend's transmission. We were trying to launch it from neutral. High RPM and slam into drive.
how the hell is a cop gonna be able to tell if im in neutral?
Eagle vision
Andrew Mayo It's for when you get in an accident. The insurance won't cover anything if you crash your car while in neutral.

This is very basic, some of these abuses of the "slush-pump" horrify me...in our teens we abused many Powerglides and learned the hard way, although they were amazingly tough...excellent explanations from Jason as usual.
How the hell are the cops supposed to figure out you're coasting in neutral
Thank You.
It's less of a criminal thing and more of a liability thing.
Hahaha
Also wondering how you're "giving up control" if you coast. If you need to speed up, you can put it back to drive. No one said they're switching to N and ripping off the selector...
They utilize Mobile Waterboarding Units to coax a confession out of innocent motorists.
Never admit to terroristic neutral coasting on public roadways!

Need a second channel titled Mangos Explained
I heard there are many ways to prepare and eat them.
August Nixon Funny! The methods of eating them apply to many fruits.
Before I watched this video I didn’t know all the ways to eat a mango... now I do
First, slice along the pit, both sides; second, cut a cross hatch pattern into the flesh; third, bend the skin back away from the flesh; fourth, bite each cube of flesh off the skin.
Thats the easter egg ! Not many people wait till the end.
Torque converter is always full of transmission fluid and rotates as one assembly, not in separate halfs like you showed. The turbine can sometime rotate separately from the housing, but mostly it's the stator in the middle that does the "power transfer". People in the know knows this, but not everybody and it might confuse them. Also, hold the brake and accelerating at the same time causes what is called "Converter stall" when impeller from the engine is supplying all the torque, but the turbine on the trans end cannot move. If held for more than 2 minutes, the torque converter can overheat.
2type of converter
high rpm stall and low rpm stall
+February Everyone I know revs and is Gone in 60 Seconds...
As a new driver, I am glad I knew not to do any of this. Granted, without real reasoning.
Also, the tip about launching was really helpful too. Again, even though I sort-of already had figured it out. It's really nice to have someone who knows what their talking about reinforce the knowledge you already had.
Why do you believe it?
11:00 You’re over explaining this. Just shift to neutral and apply brakes if your accelerator is stuck. Why would you choose fight the engine lol

Been driving manual cars for years and got my first automatic so interesting info here.
Guess I have not done anything you're not supposed to do but it's about time to try and launch it in a proper way 😁
Two questions:
1. How would law enforcement know that i'm coasting down hill in neutral?
2. Is it bad to leave my car in park with the AC on?
1. The car will sound different.
2. No, but A/C uses more fuel.
Law enforcement wouldn't know because of the sound lol. They wouldn't know period
idling for long periods of time is bad for it.
IF you should get in an accident that might have been avoided except you had no control of the car because you were rolling it instead of driving it ... then you might not only have the accident but also find out you are the liable party, because you were violating the law at the time. ?? Anyway, since you can react faster if you don't have to shift out of neutral into gear, why coast?
True, I would not admit I was coasting right before a collision.
Name: 5 things to never do in an automatic. Ending: “who knew a mango was such a versatile fruit”
When sitting in drive at a stop light and the engine rpms are lower, the engine also gets a richer air-fuel-mixture for it not to stall. So the difference in fuel economy should only be the amount that the torque converter heats up over time by being spun at the one end but being blocked to spin at the other.
1 thing you should never do in an automatic transmission vehicle: purchase one
Then you are limited to certain cars. Some luxury brands are only available in automatic

+TheMausymaus lol, alright
There is a very good reason to shift into neutral at a stoplight, but neither stress on the transmission nor fuel savings is it. The reason is to avoid moving forward (into the back of the vehicle in front of you or, far worse, into cross traffic) if your foot slips off the brake. This could occur because of simple slipperiness or distraction - the dog or the kids or whatever.
Agree, adding the fact that if you've been driving for a long time, and a stop-light that lasts for more than 3 minutes is quite tiring, may even result for you to let loose the breaks and slowly move the car forward.
That's why "Never put your gear on Neutral on stop-light" is quite strong, probably better "There's no need to put your gear on Neutral on stop-light sign" would be precise. I also cannot hear him say anything that could damage the car in doing this.
My rule is always been, if the traffic lights is 3 mins+ before it go, then I set it to Neutral + Hand break (just making sure I don't mistakenly move the vehicle).
As someone who learned on a manual transmission it always feels like neutral is calm when stopped. Automatic feels like the engine is fighting the brakes. Waiting in the drive thru fast food line my car is asking me to please disengage. It seems like not shifting to neutral or park is like riding the clutch. There must be friction somewhere.
This explains why some don't trust automatic for towing as there is never a complete metal to metal lock up.
Great job on all of your tech break downs.
Brb, gonna coast down a hill in neutral with my engine shut off
I did that in my civic it locked the steeringwheel and ignition switch. I pulled the Ebrake and the brakes and was able to stop easily. lol not a good idea if you need to turn
@Connor brakes will also not work as they should and you will need to press A LOT harder if you get into some sort of trouble
@Connor Ok but modern brakes have vacuum assist (so you can brake with a light tap) that doesn't work when the engine is off. Don't do it in a modern car.
@@peterf.229 Because you turned the key to the lock position you big dummy
@@user-njyzcip There's enough vacuum when you shut down the engine for a good stop, you'd have to intentionally force it out (you'd need to pump the brakes; just holding the pedal down won't just run out of assist)
Sure, my car cuts off the fuel to the engine when going down a hill in gear - but this causes the engine to induce drag through the drive train, requiring me to accelerate up the next hill rather than coasting over it. I contend that I use more energy accelerating up a hill than I save going down one in gear. I don't buy your argument and, unless coasting actually damages the transmission, I'll continue doing it.

If you shift to neutral and then have to apply the brakes you're wasting energy: engine consuming gas to keep idling + brakes throwing away kinetic energy as heat.
The induced drag you feel coasting in gear is the amount of energy it takes to rotate the engine, yes it's noticeable which is why idling wastes gas! To minimize drag you can upshift to keep RPMs just above the normal idle speed of the vehicle.
I was once on the high way in my parents 2000 Toyota sienna, and I bumped the Transmission into reverse at 100 kph. big bang and the engine stalled, but started right up and has been driving since with no issues what so ever haha.
I pushed R instead of L on a Chrysler push button car when going about 30. Fortunately they were designed to shift to N if you made that mistake.
I knew a guy that would go 1-2-3 then D and coast in neutral and SERIOUSLY believed he was driving manual lol
When I park my car, like at an incline i always put it Neutral then pull the handbrake, release the brake pedal, making sure it rests on the pads and then put it in P. Its just feels better to know the whole weight of the car rests on the handbrake and not on the '' locking pin '' =)
+Nick Hammer thumbs up !
I balance my truck. manual trans and non working parking brakes.
Do not turn you car off frequently at red lights you might save gas but you will wear out your starter. Starters are not ment to handle continuous turning on. They have to move a lot of weight to move pistons and flywheels that's why they use a lot of amperage. BMW found a way to put less stress to starters in their new vehicles that turn off and on at red lights. Regular engines cannot do that without putting unnecessary wear on a starter.
Fernando Ramirez that explains why I hear some engine turning on instantly at red lights or drive throughs
Light hybrid actually stop the engine and restart when you step on the accelerator. The starter is bigger and belt driven, not geared through the flywheel. Some trucks get 20% better MPG using this.
Raymond Ramírez no starter is belt driven, you can not put enough Torque on a regular belt to crank a engine over. You must be thing of a alternator that is belt driven.
Some cars have smart tech that can fire the engine up without the starter, it use the crank sensor to find out what pistons is at TDC and it injects fuel and fires the spark plug to crank it over.
Car's with start /stop tech have bigger/stronger starter some are even geared so it's less stress on the motor. The alternator and battery are also larger to cope with the number of starts
Fernando Ramirez pretty sure your starter motor has a shitload of tolerance in it
If it doesnt, send it back for replacement under warranty
Most new cars have stop start technology anyway im.pretty sure theyve tested that before they decided to make it a selling point
Satveer Degun there is NO tech to start a car with just firing, that is the dumbest comment I've ever heard. There are continuous duty starters out there made for this
What am i doing here ? I dont even have a car.
Trivial safety tip from an ex-driver. If you're at a set of lights, it is good practice to learn to apply the emergency/park/hand brake. Why? The forces applied to your body (and sometime the surprise) if you get rear-ended will pull your foot off the brake, causing your vehicle to ricochet forward, sometimes clear across the road or possibly into cross traffic. Having the handbrake applied mitigates that lurch forward and may prevent a more serious situation. Just remember to release the emergency/park/hand brake when the lights go green.
yeah, i always try to put it in neutral and only tend to apply the handbrake if i think i’m gonna be staying there a while, but i try to keep my foot on the brake until there’s someone stopped behind me as well
I put my car in Park while going downhill.
Edit: is it just me or are transmissions way too fragile?
AXLEGREASEframeset Introduction to capitalism 101: Everything must be able to break.
So, AXLEGREASEframeset, AUTOMATIC transmissions are weak as hell and are designed for pussies!
You need a MANUAL transmission. They are strong and are for people who can actually drive. When going downhill, put it "R" (for "Really slow").
HACK: double clutch to do this.
No need to than me, bro. Just post a vid showing how this works.

Senor Mofeta BRO, you're such a scrub. R is Race Mode. You shift into it once you get past 5th gear. My nonexistent little brother knows that. ...if he existed, that is. In that case he'd be all like 'duh'.
Nah put it in reverse. You'll go downhill faster
"R" is for Rocket mode, obviously :D

+Josh Williams Well, you have a tank of highly volatile and explosive liquid, and a chunk of steel that makes on average about 100,000 watts of power and 300,000 watts of heat, that's a lot of energy to tame...
+Josh Williams But at the same time, for metal contraptions that can (usually) go over 80 MPH, they're pretty safe.
+Josh Williams As an ex mechanic, you're not the only one. Believe me. I've got more stories than i can remember fully about what people do to their cars. But mostly, cars can really take a lot of abuse without breaking. Just don't expect it to last as long as it would have otherwise, and expect the repair bill to be expensive.
+Campy lol that'll last you till after ww3
+Josh Williams Yes. If a lever moves at the wrong time it breaks a car. That's why cars are stupid - lever should not move at the wrong time if someone tries it at the wrong time. This start by button is also stupid - I wanted to turn off a radio and I turned off an engine, at least I wasn't moving too fast.
Excellent video! I am guilty of shifting into neutral for a long coasts to gain maximum fuel economy. Never considered that the engine stops sending fuel in a coast! However, I know it causes great drag in drive. Brilliant video! Thanks.
I stopped the video when he said you shouldn't put it on park while the vehicle is moving>> Really? Who does that?
someone who drives manual always and then the odd time drives auto, i always put my manual into 1st while moving coming to a stop and pull the ebrake to stop completely since i use it anyways. so going into an auto its just habit to go the direction of 1st which happens to also be the direction of park
retards do
australians
Oh there are ppl
buddy of mine did it and seized the tranny, rocked it back and forth until it could move again.. now he has to use neutral and his e-brake to park lol
Thanks for the effort you put in on this video. I’m uk and not everyone would understand this let alone understand a manual car. Automatic transmissions are a thing of beauty these days and should be understood. Tough to get a lux car without one and in uk a lot of drivers don’t get the transition or nuances. Great video and top effort.
He's right about unnecessary shifting into neutral while on steep decline. The vehicle compensates for the angle of decline as he stated in his video. My truck downshifts my transmission, I slow down and my MPG indicates that I'm gaining in MPG. the process is not without a real sense of "jerky-jerkiness" as the truck begins to ascend on the next hill, it takes a second or more to reconfigure the shift algorithm and then find the gear while it begins to accelerate almost simultaneously. It's not perfect but I let it do its designated job. I've encountered this countless times in my '12 Tundra and I understand it was programmed for fuel economy and liability. The only time I shift into neutral is when i'm on a level road and approaching a stop light/sign and I wish to save my brakes unnecessary heat during hot, summer months. My truck won't be surging against my brakes and my rotors can cool off.
Georgia Fan of course it doesn't mean you have to do it on every hill if it's up and down, only when it's downhill to a stop or red light just like you're doing on the level so you can shift to D from a stop or slow roll. Also for breaks I've made mine last long by 'tapping' them for a couple seconds until I'm down to around 30-40 mph and then fully stopping from there. I drive a 4x4 with a v8 so the vehicles pretty heavy and I've found that to work
Hello,
One reason I put the gear in neutral at a stop is to reduce stress on the brakes.
I only watched this video for the Mango facts.

Imagine someone asking u why you got arrested and u say "i had my car in neutral"😂
I experienced a situation where coasting in neutral saved the day! Driving Out of the mountains, down hill, on I-70 into Denver on a snow-covered (with ice) road in a front wheel drive mini-van. I was doing around 30 mph, but when I let off the gas, the speedometer read 10 mph - in other words the front tires had no traction, no capability to steer. I put the van in neutral (several miles) and pumped the brakes until the van slowed, and could return to normal driving. Very scary at 3:00 AM!! Made it back to Chicago later that day.
I’m amazed how strong brakes can be. Whether peeling out in a car or launching a jet. The Blue Angels can demonstrate to passengers how it feels to be launched from an aircraft carrier. The pilot locks the brake, raises the engine thrust, then releases the brake for instantaneous acceleration.
Brakes will stop any engine. That information should have been given to folks who fear "unintended acceleration." If your engine does over-revs in gear, the brakes - even on the worst car - will stop it. My revivifier had a Fiero that demons would possess periodically, but the old-fashioned, crappy brakes could stop it.
Lmaoo at the people who put their vehicle in park while it's still moving
I love how he has his seatbelt on while parked
Lol
Must've been thinking of those times he was rear ended ;)
Or his car make an annoying beep when he has it unbuckled.
Safety first.
Because he leaves the transmission on D during his presentation…
Dragging engines down hills chills them from the continuous high vacuum at elevated RPM. Fast thermal cycling is hard on parts. I drive MT and use neutral (with some revs for fluid circulation) or at least top gear for extended downhill. Lack of control? Illegal? Not a concern. The few AT’s I’ve owned didn’t exhibit issues with using neutral down hills or at lights. I agree tho on neutral drops to launch: no bueno.
Sitting in drive wastes fuel and drags on engine internals while there’s relatively low oil pressure/circulation and poor sling off the crank. 2k rpm is engine break in speed for this reason. Bogging an engine below 2k while driving is even worse.
Not being contrarian I just disagree based on theory and experience. Great vid nonetheless thanks for posting and especially the casual torque converter 👍
You must be joking
i know that by my vehicles fuel monitor i get better economy by leaving in drive for going down hill verse coasting.
A thousand years ago, when I was in college, I would regularly borrow a friend's 1972 Satellite Sebring which had a really cool (for the time) floor mounted shifter. One night whilst playing Speed Racer with his car, I accidentally shifted from Drive into Reverse at about 40 mph. There was a loud noise, the engine stalled, and the car came to a sudden stop. I restarted the car and drove home without incident.
I didn't mention what I had done and about five of us drove the car on a regular basis for the remaining seven months of the school year without a transmission problem. At the end of the school year, he graduated and bought a brand new car.
I finally told him about the incident about twenty years later.
I don't recommend this as a regular practice but offer this story as an example of how old cars were built to take abuse.
Gold Winger If after the incident the car drove without issue for the next 7 months, why did you wait 20 years to tell your friend what happened? 🤔 So, if you slept with your friend's wife, maybe you would write your confession on a piece of paper, putting said confession in a glass bottle, then throwing it out to sea to be found and read 70 years later 😉
@@user2144 Simple, I didn't know if the transmission was unscathed from my faux pas or if it was living on borrowed time.
As for the second question, having sex with his wife lacks the potential for causing her permanent harm and there is no humerous context in which you can say, "Dude, I banged your wife!"
Thank you for the explanation on the shifting from drive to reverse and vise versa. I tend to do this to not take long when trying to get out of a parking spot or stuck in a tight area. Did not know about that band being in danger and hard to access, Ima do complete stops now before shifting. Thanks man I'm the type who likes to take care of things and make them last long but it's a bad habit I picked up from my pops and didn't know it was possibly doing harm.
Things you can do in a manual without having to worry:
Coaster in neutral.
Wait at stop lights in neutral.
Launching is still eh but a little less oof.
I've driven only manual cars for 21 years, I'm just about to drive my first automatic.
This is awesome, I did a lot of other research myself on how stuff works which was a blast but here I am learning so much practical knowledge on what I originally thought was just myth and not that big of a deal. This is what I originally thought would make the internet so amazing, knowledge like this at the click of a finger! Thanks for doing these, amazing!
For #4, a reason to put it in park at a stop light is so that if you get rear ended and incapacitated, and your foot comes off the brake, the car doesn't keep inching forward into traffic.
For #5, yes, some cars will allow you to throw it into park while moving, at least at low speeds. I was driving my wife's Chrysler 200 on a road trip and accidentally flipped it into park as I was coming to a stop in a parking lot. I usually drive a manual and popping the car into neutral while I come to a stop is an ingrained behavior, which is why it happened. The car was going slow enough not to cause damage, but I definitely felt that pin engage.
For #4 why don’t u just engage the handbrake?
Reving your car up while in neutral and putting it into drive was properly called a "neutral drop" in my day, young man ;-)
one of the reasons why you guys were best friends with your mechanics
+Louis Laszlo , is that because you drop your transmission all over the ground ? :-)
I've never heard of a neutral drop but have done reverse drops before I've got a cavilere to smoke the tires that way lol

I actually watched this video expecting to learn how to eat a mango. thank you for meeting my expectations.
You twice referred to “saving fuel economy”, and I believe “saving fuel, or gaining fuel economy” is the correct way to say it.
Good information; thanks.
Fuel economy is calculated by mileage covered and gallons used per minute and engine demand. So your car will give you the wrong estimate if your car is in neutral at a stop, but engine load is reduced a lot if you're in neutral, then if you're in drive. In drive at a stop, the demand is slightly more to keep the engine running at an acceptable RPM so the engine can idle under load from the transmission. Think of it as a bodybuilder holding his arm straight out with a 20lb weight for 15 minutes, as opposed to holding his arm straight out for 15 minutes with no weight.
Modern automatic transmissions will disengage the clutches and brake bands by themselfes when the vehicle is not moving and the brakes are applied. Thats basically the exact same thing as when the driver puts the transmission in neutral. As soon as you lift your foot off the brake pedal the transmission engages the first gear and you are good to go
Yes, but you have to keep your foot on the brake all the time. In "Neutral" you can rest your foot.
exactly....!!!
Uh no. An engine uses less gas at a lower speed than at a higher speed, regardless of load. If it used less gas at a lower load it would risk predetonation.
In either case, you're getting 0mpg for that duration, but having the engine burn extra gas while at a stop would decrease the average fuel economy by increasing the total number of gallons burned for the same amount of distance travelled.
Maurice Thompson He said 0.3 gallons per hour. So the car calculates this based on time, not distance covered.
Oh man, This was the best video ever! Who knew there were soo many ways to eat the humble mango!
