How a Manual Transmission Works
ฝัง
- เผยแพร่เมื่อ 23 ม.ค. 2022
- Here’s a look inside a longitudinally mounted front wheel drive manual transmission to see what’s inside and how it works.
This manual transmission came out of a 2002 B5.5 Volkswagen Passat. It is a front wheel drive car but has a longitudinally mounted engine (which is often found in RWD setups). It has a 5 - speed manual transmission with reverse. In this video we tear into the setup, including the input shaft, countershaft and front differential. In addition, we examine the three shifter forks that are responsible for the gears; 1-2, 3-4 and 5-reverse. We also shift through each gear to see how the shifter forks move, the collars slide, and synchronizers to control the gear ratio.

Another good lesson today, really helped me understand how synchros work. Thanks speedkar99👍🏼
Glad it helped! Thanks
This was better than any animated explanation of how these work. I enjoyed seeing what the synchros actually look like and how it all fits together.
Thanks. I prefer physical teardowns over diagrams and theory too
This is quickly becoming my favorite channel on yt. Nice teardown!
Thanks! What is your favorite channel ?
@@speedkar99 Probably your neighbor AvE
Love it when dig into the nitty gritty details of a car part. I really love it when you point to a subpart and explain what it does. Thank you. 👍
Thanks! I love this and learn as I go as well.
I love how simple are manual transmissions and how it works as good as DCT's and autos.
Thanks for making these wonderful videos! Love the teardowns, combined with the detailed explanations of how things actually work while demonstrating the actual parts. I always wondered how the gears don't grind when shifting and what the synchronizers were physically. Awesome educational and entertaining content! Keep it up!
Thanks I'm glad it helped you understand how manual transmissions work!
You are the absolute best man thank you as a young person getting into the automotive industry you are helping immensely in answering the questions I have
I just learned more about manual tyranny's than the four years I spent in Auto Mechanics class in High School. I really do enjoy your videos. They are very knowlagble. Keep them coming. You should do one on how the Wankel rotary motor works. That be a good one.
Agree, There's nothing like tearing something down to see how it works if you want to learn. Wish I could get a rotary but they're too expensive atm
Great detailed explanation. And you used my favorite tool, the angle grinder, when all else fails I reach for this!
Same! I love my grinder
And usually most of all fails🤣
Possibly the best explanation of manual transmission function in existence.
Wow, this is the best explanation of how a manual transmission works. At least for me. The whole concept finally "clicked". Thanks!
You are welcome. Glad it helped
Best part of the video (besides the great teardown) is the efficient use of the wife's tank top. Being middle of winter in the Great White North she won't be looking for that top for at least 6 months. You'll honestly be able to say you haven't seen it in a really long time!
Haha that's right!
I'm aiming to be Master ASE'd by fall. I love your videos, they help me understand the stuff I don't get to work on, thank you so much!
JUST finished watching your "How an AT works" video ten minutes ago, the algorithm knows the future I guess. Love your breakdowns
Nice! Which transmission do you prefer?
@@speedkar99 I bought a Fiesta over a year ago just to try out a manual and I've loved it. I'm going to at least test drive a DCT (Elantra N maybe) after this to get a taste of everything but that's years off for now.
I admire transmission designers. And a good manual gearbox is such a joy to operate - I like those from Porsche, Honda and Mazda (in that order).
Me too. Especially complicated automatic transmissions
Niicee. Always wondered how they had FWD with an engine mounted longitudinally
Me too! Until I opened this one
You do a really clear and thorough job.
Thanks
I love this snap thing removal tool, very specialized item indeed
I enjoy using my grinder too
I found the synchronizes on reverse to be very handy for rolling directional changes, as well as preventing grinding when shifting to reverse.
It works but it's not good for those syncros
@@speedkar99 it does give you a more refined experience though
i cant believe it, i have finally understood how a manual transmission works. quite easy compared to how the automatic transmission works. am going to let my car deal with that as compared to stick shift. This was a wonderful lesson. Hope ur wife doesnt go all over the house looking for her top hehe. Great content
I'm glad it helps. Definitely easier than an automatic. What the wife doesn't know wont hurt
I just found you in my recommended and this has been the most educational day on TH-cam for me in a long long time. Thanks for excellent quality and information!
You are welcome! Glad you could learn something cool
Thank you Mr speedkar99
Welcome
I'm feeling much better about my transmission now. Much less to go wrong or wear out than an AT.
Awesome video. Thanks. I always wondered how the FWD and the longitudinal engine of the B5 are realized. Interesting also how VW switched between longitudinal and transverse engine forth and back and forth again… for the Passat.
Yeah I find it quite interesting when I was examining one in the junkyard. Unfortunately all the weight is a head of the front wheels...
So well done. Thank you for demystifying that and many other vehicle mysteries. I'm hooked.
I'm surprised you don't see more wear on the synchronizer, it seems to do its thing just by a close press fit. Also I didn't realize those collars also spin, so there is constant friction with the forks.
The forks have a loose fit with the collars. Everything is lubricated as it's filled with fluid. The synchroniser only wears for the half second it takes for you to move the shift lever from neutral into a gear. After that, it does not have to resist motion, unlike a clutch pack in an automatic transmission.
No brainer to subscribe I am a fan now. You definitely know what you are doing💪
"Snap ring removal tool".
That is some fancy specialized equipment you have there. lol
Yep. Gotta use whet I have for stupid snap rings
Wow I finally know why all of my manual cars have that “whirring” noise in reverse and that it’s normal.
Thanks. Love this teardown content.
Welcome
Just found your channel, great work, I'm excited to watch more
Keep watching and share amongst your network
Fascinating video.
Awesome thanks
Ever think about tearing down a semi transmission with a 10 speed, 13 speed or 18 speed?? That would be so cool to see how they work compared to a traditional 5 speed.
That would be sweet. Wonder where I could get one from though....
Big old gears without synchros. They look like a 5 speed inside with one or two hi/lo range boxes. They're fun to drive once you get the hang of them!
I appreciate your videos brother
You are eWelcome

*Pulls out an angle grinder*
magnificent
Gotta use what I have 😎
Good work
Thanks
i will use my girlfriend’s tanktop for all my engineering needs now. thanks speedkar ♥️
Good idea
@@speedkar99 thank you. planning on testing how various automobile fluids soak up in her dresses and see just how well made designer fabrics really are. what a fun experiment i have to look forward to this weekend!
He does not nearly get enough credit for all of the wife material jokes. They crack me up everytime.
Had to use what I had on hand lol
I do love your very informative sessions. How is the snow?
The great thing about driving a car with a manual transmission is that operator skill directly affects wear on a clutch and manual transmission. Learn how to drive a car with a worn clutch and worn synchros and once you have mastered that, a new clutch and transmission can be made to last the life of the car. For example, engaging the clutch at idle or just above idle, not riding your clutch with the foot once engaged, preventing excessive slip, not resting your hand on the shift lever, and shifting gears and making a momentary pause to allow the synchro time to equalize speed - just some techniques to optimize the life of the clutch and transmission.
when you said snapping
removal tool and pulled out an angle grinder that made me laugh.
Nice
Thanks
You make incredible videos and your knowledge / understanding of this stuff is incredible! I’m always laughing at “my wife’s tank top” type of stuff hahah - I just imagine you going into your bedroom and grabbing a bunch of clothes hahaha.
Yep, gotta grab what I can. She won't mind, she buys new stuff all the time
Wow... I dunno about it being nose heavier than any other fwd car.
Since the transversely mounted fwd car still have their engine and box mounted in front of front axle anyway.
Yeah but it doesn't stick out as far causing it to be as heavy. Most of them have the engine tilted over the axle
Renault 16 had the engine behind the front axle... Otherwise it had the same longitudinal arrangement.
Only four speeds though.
Good to know
That reminds me: I need a large piece of cardboard like that, but clean.
I have got alot of cardboard for videos like these
@@speedkar99 I'll download some from you channel then. Hope you don't mind.;)
Nice video beautiful but where do you buy gearbox parts from mate thankyou very much😀😀😀😀😀
I'm not sure.... maybe source a used transmission or ask a transmission shop?
So what happens when someone on the highway shifts from fifth to "sixth" which turns out to be the reverse? Totaled transmission?
The syncro will take most of the hit if anything. It most likely won't engage since the speed difference is huge
Reverse is unlikely due to the speed difference, but people do occasionally perform a "money-shift" (like 6th to 3rd or 2nd) and over-rev the engine. The Humble Mechanic had a video about that, I believe. Not the same thing what you are asking about, but related.
The engagement won't take place. You are going to hear a loud grinding sound and stop your self by instinct. Now if you are determined to "shift" then you can pull the lever until the teeth of the gears are turned to dust or most likely a gear breaks. After that it's mine and every other Mechanic's headache xD
Is it possible to see a teardown of a transverse engine w/ fwd transaxle?
Yes I've done a manual transmission teardown from an accord transmission last year
You should do a mechanical review of the new Ford Maverick hybrid.
Hey Speedkar99, can you make a video on how to do undercarriage cleanliness and maintenance of a car/SUV ???
In neutral, clutch engaged (pedal not pressed), there is a bearing noise when outside temp is below 32 degrees. The noise goes away when engine warms up. I'm afraid it will be a costly repair
Could be that pilot bearing
Thank you. I'm looking for a recommendation for a new sedan, for example, either a Mazda 6 2.5L naturally aspirated or a Toyota corolla 2L naturally aspirated. Which one is more reliable on engine transmissions and low maintenance costs, and which is more affordable?
I'm looking for your best suggestion regarding the purchase of a sedan Mazda 6 2.5L or corolla 2L
Find a Getrag MT-82 from a Ford Mustang GT and why they fail. Makes a good video
Good idea
From what I read, it is down to inferior materials.
@@cernejr Made in China
Why do I sometimes need to release the clutch a bit while applying pressure on the shifter knob when going into 1st gear or reverse from a standstill?
Something doesn't sound right... You need to depress the pedal so engine power doesn't rotate the input shaft
@@speedkar99 It's like the shifter doesn't make it all the way to the indent even though it's staying 'in gear' as far as the H patten goes. So after I realise I'm not moving I apply constant pressure to the shifter knob while slowly releasing the clutch just a little (just enough to let the input shaft slip a little) and I can then feel the shifter go that final ~3mm to fall into the 'proper' position and only then can I start moving.
@@seljer In the case of reverse, that's simply the idler gear needing to mesh correctly to engage. Because most reverse gears are unsynchronized, if the gears aren't aligned it won't engage until one gear moves slightly. Then it'll pop in. Happens on my car all the time. I either use your method or shift into 1st, then back into reverse until it engages. 1st generally doesn't suffer the same problem, however because one typically shifts into 1st from a standstill, the same principle applies. Not an issue once moving. However, unless you have a synchronized reverse, you can't shift into reverse while moving or you'll grind and wear the gear teeth.
show us a nissan 6 speed next time!! the one from the maxima
That would be cool
So a synchronizer and shift forks are similar to dogs and shift forks in a motorcycle transmission except the synchronizer performs another step?
Do you just scrap all of this stuff or what do you do with it?
Scrap or desk ornament
When is the 1MZ-FE video coming out
It's dead winter here. Cold. Snow. It'll be a little while before I can tear into that.
@@speedkar99 👍
did you work at uline? i’m trying to get an internship there. howd you like it, if you did?
No I don't
Nit picking: 10:08 not ATF, I believe manual transmissions run something like 90 weight oil instead.
Can you teach us how to drop a trans?
I have engine/transmission removal videos. But that's together as a unit
What's the code for the trans?
It is funny how he tells you what clothes he is using
Gotta use what I find lol
Snapper removing tool?
Yep. My trusty grinder
Did he say automatic transmission fluid? But this is a manual transmission...? My 2003 3.2 liter Cadillac CTS manual transmission 5 speed also uses automatic transmission fluid. Dexron III
Yes that was an error. Should be manual transmission or gear oil
@@speedkar99 no worries. My brain works in details. I'm that guy that tells the college professor when the book is wrong and actually proves it. Lol. Your lesson was awesome. I would always check to see what fluids actually go into the transmission per each vehicle I'm working on anyway research research research. Lol
This kind of reverse gears doesn't "whine" when you drive manual trans car in reverse. big thing...VW...
Yes. Because it's helical
I actually had a b5.5 Passat
Haha you have the full toothbrush this time
Yeah. I sharpen them for use in my mechanical reviews
useing that transmission can u make 4x4?
Yes that's how Audi Quattro is based on
SNAP RING REMOVAL TOOL🤣🤣🤣🤣🤣💀💀💀💀💀💀💀💀💀💀
Yep 😎
I thought the next video was going to be on hybrid car brakes ...not this
That was the next video I was going to film...not post! It's dead winter here, hard to film

7:31 awkward silence
👀
Was half asleep editing it last night whoops
🐷👍
I don't understand why you work on the floor?
You're ruining your knees
Work on the bench
You are right. I recently got knee pads which helped alot recently. However a transmission is heavy to work on a regular table.

O.k
We follow after you when you work with Little stuff :-)
Don't moneyshift 😂🤑😛
Yep otherwise bad things could happen
