what's funny is that the people who have never driven a manual gearbox on a heavy vehicle are the ones who talk the most, it's not a car, the efforts on the parts are not the same, you have to help the gearbox a little bit, as I like to say. good job , As long the vehicle is moving and you don't change parts every miles it's ok !
Been driving the cheapest car for 17 years, Dacia Logan, diesel engine mostly in the city. It has over 300000 km and hadn't had major issues. I never double clutched. Good maintanence and knowing what car you drive, so no forcong it while the motor is cold are the main things of having any car for 20 years and a lot of km/miles
First time seeing this! I guess this is to move through gears. In my manual, I just rev higher, hold clutch to the floor, then jump from say 4th to 6th no problem. Is that what’s going on in the video?
This is a 5 ton 6x6 ex military land rover, with small synchros snd a 4 speed box. Its a big jump between gears. You can float between gears, but the clutch is way easier to swap than a gearbox throwout bearing in this. Sometimes you need to match speeds with input/output shaft for smooth shifting when offroad as rev matching is not an option.
@@TovarishDima Nah you just lift the foot a touch, slip it into neutral and apply brakes - or for the less skilled, turn off the key, slip into neutral and start it up again.
I having been driving for 2 years now with a 13 speed freightliner and tend to use a mixer of double and floating (depends on load and grade) i double clutch more often then not because it just much more fluid for me and the way i was taught so 100% comfotable habit. I know my engine and can just shift when i know its time, I have been getting better floating the gears and trying to use it more but out of habit double clutch.( guys who ran the truck for 6 years prior to me was very rough on it and i think the syncro is damaged because other truck i float so easily), this is my 99% of the time work truck. I float when im on main roads or high ways, flat areas, and when it just feels right to float. Its funny because the people who say we should float are mad mean to double clutchers lol like their just horrific drivers for double clutching verse floating. Makes me kinda feel like am i not doing it enough or a good enough driver cause i have an easier time with double clutching... but hey i haul 60000lbs into the hills and back all the time into tight moutain roads full of pallets of concrete block and material off loaded into wonkey ass construction sites. 😅
Yeah I can float 4th in this, as it's a 4 speed box, but synchros in 2nd and 3rd get a lot more work, and at 5 tons, this needs a lot of room for rev matching - so I end up double clutching a lot. Technically this is 8 speeds, and I have a two speed transfer case.
If you have a gearbox like mine with small and/or worn synchros, double clutching helps the input and output shafts match speeds, meaning they will mesh more easily with less/no help from the sychro ring. Means less gearbox wear, faster shifting, and in some cases allows you to change gears where you otherwise could not. The flywheel in this military vehicle weighs 20kg, it needs some help.
@ that makes sense. I *have to* double clutch, whenever I have my modified Studebaker underdrive (originally overdrive) unit installed on the back of the T-case on my Willys Cj-2A. I now use it with the custom rock crawling gears only, because an overdrive unit on a stock-axle CJ-2A is *really* asking for trouble.
If you can drive a big rig, you can drive anything else. Double clutching is the correct way to drive a big rig… even if the old timers float the gears (and then bitch about the gear box going out but that clutch is still good!)
When you lift your foot, the clutch plate touches the pressure plate, spinning it up, when you press the clutch again, both the input and output shaft are spinning at the same speed. Most useful when trying to downshift on a downhill descent, or trying to engine break.
Never understood what the point of this was, with the clutch disengaged, the transmission is now at a different speed of the engine. To upshift, clutch in and wait for engine to drop to the right rom. To downshift, clutch in and rev match. Why do you need to fo anything else?
sometimes you don't have the luxury of time, or dead flat roads. in a 5 ton 6x6 , on rough roads, sometimes you gotta downshift in a hurry, or do the same on a steep incline to avoid loosing your momentum. In cases like this where it's an ancient 4 speed, the synchros are tiny and really only there in spirit. the LT95 boxes in land rovers are well known for snapped gearsticks, and they take a lot of force, even when correctly rev matched. Double clutching on the flat means the gearstick just floats through. But most people don't drive old military gear and have gearboxes that haven't made sacrifices in order to deal with the torque generated by this engine. th-cam.com/users/shortsw-WnvUpkxLI
@@TheAussieRepairGuy sorry I guess I'm inexperienced and genuinely just don't understand. I've been driving a 5 speed Pathfinder for a while like how I described earlier and been just fine with moderate slopes at highway speeds, but I realize that's nothing like what you drive. Are you essentially double clutching because you can't wait for the engine to drop rpm?
@@wertbe1718 No in some cases it simply won't shift. in most cases it will shift much more smoothly with a double clutch - but it's big and slow and they flywheel is huge, sometimes you just loose too much momentum and miss the window to shift. Other times I might be crossing an intersection, and don't have the luxury of a 45 second shift time, when I'm about to get t-boned by speeders on the intersecting street. Rev matching in these low geared, 4 speed off-road crawlers just simply isn't enough sometimes.
@@wertbe1718 the 4x4 version, which I also drive, is less than half the weight, and have the same engine, gearbox and transfer case, can shift without the clutch: th-cam.com/users/shorts4tAtXPOvqOc
Most vehicles you fon't need to. This is a 5 ton 6x6 military vehicle with only 4 gears. There's a big difference between gear ratios, and it needs a little help if you want to change quickly
@@adriannyqvist964 with the downshift, I'm slowing down, so I release the clutch slowly for a smooth deceleration, using the engine to slow the vehicle instead of the brakes. Basically i clutch in, take out of gear, clutch out and rev, then quickly clutch in, and select a lower gear. This spins the clutch plate up, so that it more closely matches the speed of the gearbox input.
Who knew all it took was five seconds on TH-cam to learn double clutch😂 I should tell my brother his yelling and frantic need for me to immediately understand it after he’s repeatedly yelled the same thing at me ten times😅😂
it reduced wear on the gearbox, throwout bearing and synchros, but yes it does increase clutch wear. in my case, clutch is much easier to replace than anything in the gearbox.
@@TheAussieRepairGuy Thanks for the reply! I know the general moves, but it's still tricky. She's an old girl and needs a new or rebuilt transmission. I have been trying to do it single clutch style, maybe that's the problem. I'll definitely head out tomorrow and see if I can get the hang of it though.
@@connorbaz5980 the general idea of double clutching is to get the flywheel spinning at the same speed as the input shaft. In the case of down shifting you need to spin it up a bit faster as the lower gear will want to be spinning faster.
@@TheAussieRepairGuy ahh, I understand what you're saying. In theory. I double clutch all the time going up, and sometimes going down - but never tried to rev match on a double clutch downshift.

I'm a Truck Driver (with an automatic restriction, ew) and I'm getting back OTR soon here. Looking to improve my shifting and get that license restriction removed so I can sign on with a company just down the way from me.

I don't do sneakers, and I have MS which is heat sensitive - so the cooler the better. that it's a 6x6 military vehicle, clutch takes 30kg to depress. Perspective dude - other ways of life exist outside your narrow field of view.

What is the purpose of double clutching? What is it doing? Been probably 25 to 30 years sence i drove stick. Now that im out of the big city, i miss it.
Allows input and output shafts to match speeds, reducing the need for synchros to spin up the gears. In big boxes like this eith only 4 speeds, there's a big jump between gears. Done right, you don't even feel the stick move between gears. Offroad, it can be essential when hill climbing or descending extreme terrain. See the pinned comment for more
@TheAussieRepairGuy I've driven loaded tractor trailers at 80k lbs while rev matching just fine both up and downshifting every day/year. I only use the clutch for 1st/reverse lol I'm not hating I'm just saying what I do.
@@dallasmanthie156 still, you can come demonstrate for me. I've rev matched before, but this 6x6 land rover has an odd drivetrain, where the 3rd axle is driven by an entirely separate driveshaft on it's own pto on the gearbox, not transfer case. The slack in the gears means that trying to rev match just isn't quite enough. The synchros in these gearboxes are really only there in spirit. Needs that little bit of extra help. It's also nearly 40 years old.
Any way guys let me teach you how to drive a manual, Step 1. Learn how to drive a automatic car first. Step 2. How to start a manual car, push brake and clutch all the way in and start car then put car in neutral. Step 3. How to start rolling in 1st gear, push clutch all the way in, put car in 1st, take your foot off the clutch slowly till you feel the car start vibrating, then start tapping the gas and you will be rolling after you start rolling take your foot off the clutch slowly. Step 4. How to stop the car, press clutch all the way in put car in nuteral, take your foot off the clutch, and apply brake as needed to syop like you will do in an automatic. Step 5. How to change gears, let's say you in 1st you will have to press clutch all the way in then switch the gear to 2nd then slowley take your foot of the clutch to engage the gear, thats what you do to all gears. Step 6. How to not roll back, pull hand brake up, and hold it all the way up and hold the lock button in so it does not lock in, put car in 1st and take clutch slowly till you feel the car vibrate then strt tapping the gas and when you feel the car start to pull put the hand brake all the way down but dont leave it, when you make sure you are actually rolling foreward then put the hand brake all the way down and leave it and thats how you dont roll. Tip: Learn how to not roll back or at least reduce the roll back in that way. Step 7. Another way to not roll back, if you are good in driving a manual, then this shouldnt be hard, put car in 1st and find the biting point put the car into a deeper section of the biting point and very fast take your foot off the brake and give the car gas then quickly but considerably taking your foot off the clutch. Note: all the steps i gave are the basics, how well they work with you is based on you, how fast you change the gear is based on you not me or my tips
@@TheAussieRepairGuy from my little time behind the wheel of two non synchro trucks, the clutches are monsters though double clutching just works on a non synchro so I entirely get it. Can’t beat the dealing of the synchro 6 speed international I drove though, all you need to do is gently let out the clutch with no accelerator and even with the heavy clutch weight a little heel toe blip when going down to third, or if you feel extra spicy second, at a light, works like a charm.
@@HEXAN-SC yeah you can float these, but they are a 4 speed truck box. I have a 4x4 with same drivetrain and engine. The synchros are small. I have a short going public tomorrow showing that.
@@donke666 nah I keep on top of that. Foot powder, there are socks under there that are hidden by the boots, and I'm out in cold weather, so sweating less of an issue.
clutch all in or all out, not half way. Only time you do it in increments is takeoff, otherwise you will burn it out. I'll haev to do a longer video showing how a clutch actually works. However, the idea is to get the input and putput shaft spinning at the same speed, so the synchro ring doesn't have to work so hard to match speeds. If you have ever played with lego technic, try meshing two gears while they are moving at different speeds.
@@TheAussieRepairGuy that'd be great cause now I'm lost again ~ you're foot does not look to be all out on the double, and the caption says 'lift btw gears'...maybe I'm not matching the revs properly to be so quick as your feet (06' swift)
@@psychnstatstutor when double clutching up in gears (eg: 2nd to 3rd) lift up and down quickly, so that the clutch plate touches briefly, and then change into gears without delay. when changing down gears (eg: 4th to 3rd) do the same, but rev a little while the clutch is out. every vehicle has a different feel and speed to do this at. clutch wear plays a big part, in my vehicle the clutch takes 30kg to depress - as it's a 5 ton military vehicle, and things have to happen slowly. in a "normal" car all of this happens much more quickly. smaller cars have better synchros usually, and if you hare having issues changing up gears, it might simply be that you aren't accelerating enough before changing up. basically - just send it... as you get more confident with a manual you will tend to be a little more aggressive with acceleration, and you will find things will change more smoothly. if it's a second hand vehicle - change or get the gearbox oil changed, sometimes adding a little teflon additive line nulon smooth-shift can help.
@@TheAussieRepairGuy Thanks so much for the detailed feedback; I'll practice being quicker with my clutch foot, at the mo to go all out I need to do it slow (2006 swift). Merry Christmas!
Some auto gearboxes have two clutches, so that they can engage the next gear per-emtively during races - not really something I'm gonna try in my 5 ton, 4 speed 6x6 military land rover with a top speed of 85km/h
Come and try it sometime, this is a 5 ton, 6x6 military vehicle. Bet you it doest go the way you expect. Also, any less, and it won't release. The clutch takes around 30kg to release, and takes up at the last 1/3 of the pedal travel.
this is a 5 ton 6x6 ex military vehicle with 5 speed box. sometimes I can change gears without the clutch altogether, but most of the time, the world wont wait for the 5-6 seconds it takes for this to change gears at the "right" speeds. to add to that, off road - which is where this lives most of the time, the world isn't perfect and flat - sometimes input and output just aren't going to match no matter how good the synchros are.

You'll save your sincros but your thrust washers will take a beating with double clutching. And believe me, even with single clutch operation, thrust washers will go bad way before the sincros do.
Firstly, this is a how-to, not a you-should video. this is a 5 ton 6x6 military vehicle with 4 speeds, and a heavy flywheel, and small synchros. double clutching basically helps synchronize input and output so that it shifts more smoothly and faster. in a lumbering old thing like this, it helps you get round town faster, or get it into a lower gear for downhill descents.

@@gerryger889Always push the clutch to the floor. Be lazy about the double clutch if anything as long as it’s 1 gear between, and the rest of your technique is gentle on components, modern car’s synchros most likely last until the transmission needs a rebuild.

@TheAussieRepairGuy I live off road,and I have driven a few unamogs never needed to double clutch. But I did blow the owners mind when I showed him how to flote the gears in it. A real operator doesn't even need a clutch pedal unless it's it 1st at a dead stop or reverse...
You don't need to double clutch for upshifting, only for down shifting and the only reason you do it is to get the transmission to spin faster so you can match rpms with the engine. Most full size trucks you don't even have to use the clutch. Mack trucks operators manual even states that once the truck is in motion the clutch is not necessary.

Good maintanence and knowing what car you drive, so no forcong it while the motor is cold are the main things of having any car for 20 years and a lot of km/miles
This is a 5 ton, 6x6 military vehicle with a 4 speed truck gearbox
Why is everyone so triggered by this?
It ain't the same but in truck sim i do this, especially if im in an old mack. It matters with the force feedback of a wheel
I only do this as the weight and age of the vehicle calls for it.
First time seeing this! I guess this is to move through gears. In my manual, I just rev higher, hold clutch to the floor, then jump from say 4th to 6th no problem. Is that what’s going on in the video?
This is a 5 ton 6x6 ex military land rover, with small synchros snd a 4 speed box. Its a big jump between gears. You can float between gears, but the clutch is way easier to swap than a gearbox throwout bearing in this. Sometimes you need to match speeds with input/output shaft for smooth shifting when offroad as rev matching is not an option.
Remember the time my clutch went out, so I had to no clutch. It was quite fascinating to learn
In the right conditions, clutch isn't even necessary - example:

Just rev match and you are good to go. Pray there are no traffic or lights…
@@TovarishDima Nah you just lift the foot a touch, slip it into neutral and apply brakes
- or for the less skilled, turn off the key, slip into neutral and start it up again.
I’ve always single clutched I’ve never thought about double clutching
You probably have good synchros, and a lightweight small vehicle.
The one in the video is a 5 ton 6x6 military land rover.
Still do that with the Eaton twin splitter.
Do one for heel-and-toe braking
I value the shape of my nose lol.
I having been driving for 2 years now with a 13 speed freightliner and tend to use a mixer of double and floating (depends on load and grade) i double clutch more often then not because it just much more fluid for me and the way i was taught so 100% comfotable habit. I know my engine and can just shift when i know its time, I have been getting better floating the gears and trying to use it more but out of habit double clutch.( guys who ran the truck for 6 years prior to me was very rough on it and i think the syncro is damaged because other truck i float so easily), this is my 99% of the time work truck. I float when im on main roads or high ways, flat areas, and when it just feels right to float. Its funny because the people who say we should float are mad mean to double clutchers lol like their just horrific drivers for double clutching verse floating. Makes me kinda feel like am i not doing it enough or a good enough driver cause i have an easier time with double clutching... but hey i haul 60000lbs into the hills and back all the time into tight moutain roads full of pallets of concrete block and material off loaded into wonkey ass construction sites. 😅
Yeah I can float 4th in this, as it's a 4 speed box, but synchros in 2nd and 3rd get a lot more work, and at 5 tons, this needs a lot of room for rev matching - so I end up double clutching a lot.
Technically this is 8 speeds, and I have a two speed transfer case.
can i ask what's the difference between single and double clutch when up-shifting?
If you have a gearbox like mine with small and/or worn synchros, double clutching helps the input and output shafts match speeds, meaning they will mesh more easily with less/no help from the sychro ring. Means less gearbox wear, faster shifting, and in some cases allows you to change gears where you otherwise could not. The flywheel in this military vehicle weighs 20kg, it needs some help.
Is this for rev matching?
@@Braaaaaaap basically yes.
Or.. just Rev match 🙌
yea fr
I stopped double clutching and just float the gears once I'm moving
@@whataboutbob7967 yeah that's possible on the highway, off-road is a different matter
I still prefer the single clutch on downshifting, tried double but it's too much extra time in the hilly terrain
@@GoatPopsicle in this thing, it's sometimes the only option. 5 ton 6x6
@ that makes sense. I *have to* double clutch, whenever I have my modified Studebaker underdrive (originally overdrive) unit installed on the back of the T-case on my Willys Cj-2A.
I now use it with the custom rock crawling gears only, because an overdrive unit on a stock-axle CJ-2A is *really* asking for trouble.
If you can drive a big rig, you can drive anything else.
Double clutching is the correct way to drive a big rig… even if the old timers float the gears (and then bitch about the gear box going out but that clutch is still good!)
@@Sir_Austin_T_Gee this is a 6x6 military land rover.
Floating doesn't hurt the gear box. Unless your doing it wrong.
I need some help here: Can’t I just keep my foot on the clutch when blipping the throttle? What does double clutching do different?
When you lift your foot, the clutch plate touches the pressure plate, spinning it up, when you press the clutch again, both the input and output shaft are spinning at the same speed.
Most useful when trying to downshift on a downhill descent, or trying to engine break.
Never understood what the point of this was, with the clutch disengaged, the transmission is now at a different speed of the engine. To upshift, clutch in and wait for engine to drop to the right rom. To downshift, clutch in and rev match. Why do you need to fo anything else?
sometimes you don't have the luxury of time, or dead flat roads. in a 5 ton 6x6 , on rough roads, sometimes you gotta downshift in a hurry, or do the same on a steep incline to avoid loosing your momentum.
In cases like this where it's an ancient 4 speed, the synchros are tiny and really only there in spirit.
the LT95 boxes in land rovers are well known for snapped gearsticks, and they take a lot of force, even when correctly rev matched. Double clutching on the flat means the gearstick just floats through.
But most people don't drive old military gear and have gearboxes that haven't made sacrifices in order to deal with the torque generated by this engine.

however --- if you have a read through the comments, this has been said many many times already. and this is a question I keep having to answer daily.
@@TheAussieRepairGuy sorry I guess I'm inexperienced and genuinely just don't understand. I've been driving a 5 speed Pathfinder for a while like how I described earlier and been just fine with moderate slopes at highway speeds, but I realize that's nothing like what you drive.
Are you essentially double clutching because you can't wait for the engine to drop rpm?
@@wertbe1718 No in some cases it simply won't shift. in most cases it will shift much more smoothly with a double clutch - but it's big and slow and they flywheel is huge, sometimes you just loose too much momentum and miss the window to shift.
Other times I might be crossing an intersection, and don't have the luxury of a 45 second shift time, when I'm about to get t-boned by speeders on the intersecting street.
Rev matching in these low geared, 4 speed off-road crawlers just simply isn't enough sometimes.
@@wertbe1718 the 4x4 version, which I also drive, is less than half the weight, and have the same engine, gearbox and transfer case, can shift without the clutch:
th-cam.com/users/shorts4tAtXPOvqOc
when I downshift, Its clutch in, shift, dab of brakes and then clutch out. Stops from engine braking.
Whereas I'm relying on the downshift in order to engine brake.
Is a double clutch downshift gonna speed it up or slow it down?
double clutching on the downshift helps to get it into gear when you wish to engine brake.
@@TheAussieRepairGuy so its for semis?
@@insertnamehereofficial this is a 5 ton, 6x6, 4 speed military vehicle, with a truck (semi) gearbox.
@@TheAussieRepairGuy oh, that's freaking sick
What's the main porpuse of double clutching.. does it work in any vehicle?? I'am just curious
Most vehicles you fon't need to. This is a 5 ton 6x6 military vehicle with only 4 gears. There's a big difference between gear ratios, and it needs a little help if you want to change quickly
@@TheAussieRepairGuy I see got it thank you... I really appreciate you reply... Blessings
Heard of doing that changing down but don’t understand why you would changing up
When engine braking, it's pretty hard to change down a gear when there's a huge speed mismatch.
single clutch for me and rev match downshifting no need for the extra pedal movement
yeah you are probably not driving a 4 speed, 5 ton, 6x6, 30 year old military vehicle
I go from.say 5th to.3rd all.the time I don't lift the clutch twice only once.
If you have good synchros, and your vehicle isn't a 6x6, 5 ton military land rover, tbat works fine.
If you don’t double clutch, Torrettos going to get mad. 😠
That reference is lost on me unfortunately

@@TheAussieRepairGuy they are a meme heaven.
Does this also work with a tractor from the 80s thats a manual?
And also could you give a little more information on how to downshift like you did in the vid?
Tractors would work, but tend to be a little more direct with shifting.
@@adriannyqvist964 with the downshift, I'm slowing down, so I release the clutch slowly for a smooth deceleration, using the engine to slow the vehicle instead of the brakes.
Basically i clutch in, take out of gear, clutch out and rev, then quickly clutch in, and select a lower gear.
This spins the clutch plate up, so that it more closely matches the speed of the gearbox input.
@@TheAussieRepairGuy Thank you I will remember this next time I drive!
Who knew all it took was five seconds on TH-cam to learn double clutch😂 I should tell my brother his yelling and frantic need for me to immediately understand it after he’s repeatedly yelled the same thing at me ten times😅😂
Takes a bit of learning the right feel and sound for each vehicle. This is a 5 ton 6x6 with only 4 gears, its a big leap between gears and a slow box.
Why double clutch on gear shift?
@@เlเ-b4o you don't drive a heavy vehicle I assume?
Double clutch just puts more where and tear in it
it reduced wear on the gearbox, throwout bearing and synchros, but yes it does increase clutch wear. in my case, clutch is much easier to replace than anything in the gearbox.
In cdl class now ,n i can't get out of 3rd
sounds like you have some drivetrain issues.
if your CDL is air actuated, my might have a vacuum leak somewhere.
Still having trouble with the downshift timing...
Clutch in, gearstick to neutral, clutch out, rev, quickly clutch in, and move into lower gear.
@@TheAussieRepairGuy Thanks for the reply! I know the general moves, but it's still tricky. She's an old girl and needs a new or rebuilt transmission. I have been trying to do it single clutch style, maybe that's the problem.
I'll definitely head out tomorrow and see if I can get the hang of it though.
@@connorbaz5980 the general idea of double clutching is to get the flywheel spinning at the same speed as the input shaft. In the case of down shifting you need to spin it up a bit faster as the lower gear will want to be spinning faster.
@@TheAussieRepairGuy ahh, I understand what you're saying. In theory. I double clutch all the time going up, and sometimes going down - but never tried to rev match on a double clutch downshift.
Definitely give it a try tomorrow. Got a few good low-traveled roads around me.
I'm trying to learn all the good old ways of driving. Sick of autos TBH. I'm a Truck Driver (with an automatic restriction, ew) and I'm getting back OTR soon here.
Looking to improve my shifting and get that license restriction removed so I can sign on with a company just down the way from me.

Rev match instead makes for faster shifting

Not in this case, and not offroad
What is the purpose of double clutching?
What is it doing?
Been probably 25 to 30 years sence i drove stick. Now that im out of the big city, i miss it.
Allows input and output shafts to match speeds, reducing the need for synchros to spin up the gears. In big boxes like this eith only 4 speeds, there's a big jump between gears. Done right, you don't even feel the stick move between gears. Offroad, it can be essential when hill climbing or descending extreme terrain.
See the pinned comment for more
What Is this for?
To help you get it into gear when you need to shift at less than perfect speeds.
Not me who just rev matches and power shifts 😅 clutch is only for 1st/reverse
Come visit me sometime, you can drive the 5 ton 6x6, when we are flying downhill trying to engine break, I'll yell at you "just rev match!".
@TheAussieRepairGuy I've driven loaded tractor trailers at 80k lbs while rev matching just fine both up and downshifting every day/year. I only use the clutch for 1st/reverse lol I'm not hating I'm just saying what I do.
@@dallasmanthie156 still, you can come demonstrate for me. I've rev matched before, but this 6x6 land rover has an odd drivetrain, where the 3rd axle is driven by an entirely separate driveshaft on it's own pto on the gearbox, not transfer case. The slack in the gears means that trying to rev match just isn't quite enough.
The synchros in these gearboxes are really only there in spirit. Needs that little bit of extra help. It's also nearly 40 years old.
What's the point of double clutching if you can just float through gears?
Double clutching is what makes that posdible.

Its a 5 ton 6x6 military vehicle.
And yes every single person in the comments is an expert.
Any way guys let me teach you how to drive a manual,
Step 1. Learn how to drive a automatic car first.
Step 2. How to start a manual car, push brake and clutch all the way in and start car then put car in neutral.
Step 3. How to start rolling in 1st gear, push clutch all the way in, put car in 1st, take your foot off the clutch slowly till you feel the car start vibrating, then start tapping the gas and you will be rolling after you start rolling take your foot off the clutch slowly.
Step 4. How to stop the car, press clutch all the way in put car in nuteral, take your foot off the clutch, and apply brake as needed to syop like you will do in an automatic.
Step 5. How to change gears, let's say you in 1st you will have to press clutch all the way in then switch the gear to 2nd then slowley take your foot of the clutch to engage the gear, thats what you do to all gears.
Step 6. How to not roll back, pull hand brake up, and hold it all the way up and hold the lock button in so it does not lock in, put car in 1st and take clutch slowly till you feel the car vibrate then strt tapping the gas and when you feel the car start to pull put the hand brake all the way down but dont leave it, when you make sure you are actually rolling foreward then put the hand brake all the way down and leave it and thats how you dont roll.
Tip: Learn how to not roll back or at least reduce the roll back in that way.
Step 7. Another way to not roll back, if you are good in driving a manual, then this shouldnt be hard, put car in 1st and find the biting point put the car into a deeper section of the biting point and very fast take your foot off the brake and give the car gas then quickly but considerably taking your foot off the clutch.
Note: all the steps i gave are the basics, how well they work with you is based on you, how fast you change the gear is based on you not me or my tips
@@mohammadalmasalmeh6 this is a 5 ton, 6x6 military vehicle with 4 speed box. A lot of general advice is not applicable here

@@TheAussieRepairGuy from my little time behind the wheel of two non synchro trucks, the clutches are monsters though double clutching just works on a non synchro so I entirely get it. Can’t beat the dealing of the synchro 6 speed international I drove though, all you need to do is gently let out the clutch with no accelerator and even with the heavy clutch weight a little heel toe blip when going down to third, or if you feel extra spicy second, at a light, works like a charm.

clutch all in or all out, not half way. Only time you do it in increments is takeoff, otherwise you will burn it out.
I'll haev to do a longer video showing how a clutch actually works. However, the idea is to get the input and putput shaft spinning at the same speed, so the synchro ring doesn't have to work so hard to match speeds.
If you have ever played with lego technic, try meshing two gears while they are moving at different speeds.
@@TheAussieRepairGuy that'd be great cause now I'm lost again ~ you're foot does not look to be all out on the double, and the caption says 'lift btw gears'...maybe I'm not matching the revs properly to be so quick as your feet (06' swift)
@@psychnstatstutor when double clutching up in gears (eg: 2nd to 3rd) lift up and down quickly, so that the clutch plate touches briefly, and then change into gears without delay.
when changing down gears (eg: 4th to 3rd) do the same, but rev a little while the clutch is out.
every vehicle has a different feel and speed to do this at.
clutch wear plays a big part, in my vehicle the clutch takes 30kg to depress - as it's a 5 ton military vehicle, and things have to happen slowly.
in a "normal" car all of this happens much more quickly. smaller cars have better synchros usually, and if you hare having issues changing up gears, it might simply be that you aren't accelerating enough before changing up. basically - just send it...
as you get more confident with a manual you will tend to be a little more aggressive with acceleration, and you will find things will change more smoothly.
if it's a second hand vehicle - change or get the gearbox oil changed, sometimes adding a little teflon additive line nulon smooth-shift can help.
@@TheAussieRepairGuy Thanks so much for the detailed feedback; I'll practice being quicker with my clutch foot, at the mo to go all out I need to do it slow (2006 swift). Merry Christmas!
