One way that I've learned how it works is going piece by piece, first I learned ed how a torque converter works, then the fluid mechanics, then the planetary gears, then the electronics. I kinda learned it in a weird pattern but I mean after a while I understood it

[@PhunkBustA]

i love how this makes more sense that all those (probably) expensive animations and narrations

[@speedkar99]

[@MoosesValley]

Very well explained. Automatic transmissions can almost be considered to be a fluid filled mechanical computer - but instead of processing input data and generating output data, they are processing inputs (acceleration requirements, etc) and producing outputs (increased speed via smoothly changing gears). Great video. Thanks !

as a retired engine mechanic, I always wanted to know more about how the transmission worked, other than the basic maintenance knowledge to service them. This video covered that very well. Thank you sir for explaining it to me. I already knew that fluid change @ about 50-70K miles, (viscosity breakdown occurs even in trans oil) filter & pan gasket replacement is essential to keeping the trans running optimally otherwise your engine has to work harder to develop the hydraulic pressure to make those shifts thus costing you more gasoline consumption.

[@Aashishkebab]

What's wrong with CVT?

[@catsspat]

@@Aashishkebab I actually had a CVT car until early this year. The only reason I bought it was for the EyeSight(TM), which was fantastic by the way. But now that I can have manual transmission + adaptive cruise combo, I had no reason to keep it, so I traded it in. As for CVT, I don't mind CVT from technical perspective, but I can't stand them from implementation perspective. The fake ratios completely ruined that Subaru for me, where it could have been 100% smooth, it chose not to be. And that generation still had mechanical problems to boot (slipping), which Subaru knows about, as they offered free 10 year extended warranty on CVT. I have their letter to prove it. Also, I'm not sure if it was Subaru CVT specific, but it had some incredibly annoying behavior when I stepped on the accelerator while cruising, say to pass someone. It would rev up the engine, but at the same time, use more power than is provided by the engine to change the gear ratio, so for the next second or so, the car would actually slow down! It was the most annoying thing. I'm so glad I now have an MT car. Lastly, I imagine I'd have no problem with Toyota's Hybrid CVT (Planetary Gear 2-Motor CVT), but I don't have any real experience driving one, so I'm not sure.

[@Aashishkebab]

@@catsspat IO have a 2012 Outback where they don't do the stupid simulated shifting. I've never had it slow down while increasing the ratio while trying to accelerate. However the power isn't there until it stops increasing the ratio and here's why: The transmission is trying to change ratio (go into a "lower gear"), meaning that engine speed must increase. In an automatic or manual this is no issue because you would rev-match before engaging the engine. With a CVT, since it is always engaged, the engine resists this due to inertia. It's moving at a slow RPM and energy is needed to increase that. Imagine downshifting without rev matching. You'd get a sudden jolt of negative acceleration until the engine spun up to match the transmission. This is essentially what is happening but smoothly and over a longer time. It's better than automatics which literally will not do anything while shifting/rev matching. It's also why when it decreases the ratio ("upshifts"), it gives a boost of acceleration, even if you're not even pressing on the throttle. An extreme example of this in a manual is dumping the clutch. In this case, the clutch is engaged the entire time, but there is no disengagement to wait for the engine speed to settle down. I know about the warranty, I had mine replaced under that (and they put a bad one in after that, and I tried fixing it myself and ruined it and had to buy another one from a scrapyard). Maybe you can try a 2010 - 2014 Outback somewhere? It's not programmed perfectly (there are still some quirks that are annoying - for example, it takes into consideration how rapidly you move the pedal), but it acts as a CVT should.

Excellent explanation apart from the oil pump at around 13 minutes. As oil is a liquid it cannot be compressed so instead of being squeezed between the gear teeth it is moved around in the open spaces between the teeth. Keep up your excellent videos!

[@speedkar99]

Thanks for that clarification

Best transmission detailing review ive ever seen Short .. direct .. informative Despite i am a civil engineer but i realy enjoyed with this video Best wishes

[@speedkar99]

Thank you

[@nunosantiago5472]

Give me a manual any day...

[@speedkar99]

+nuno santiago I'd like to learn that too

[@demarcocb4240]

He has a video for that

[@LBCORP1960]

Brilliant video, explanation and editing! Whoever designed this thing is a genius!

[@speedkar99]

It sure is complex

[@marwanmohamed4414]

there's a lot happening inside these transmission

[@speedkar99]

There sure is!

[@ronniemartinez1070]

Best video breaking down a Automatic Transmission on KZbin Hands Down!! Subbed👍🏽

[@jerrylipezcarrillo4400]

Wtf is he saying , godamn this guy can describe making a peanut butter and jelly sandwich and I wouldn't understand a Godamn thing. Sht. I pissed ...

[@speedkar99]

Sorry if u didn't understand

[@JillyBean860]

I have massive respect for people who rebuild their transmissions. Watching this lets me know that I'll never do it myself because I'd forgot to put stuff back where it's supposed to go and my car would explode or some shit.
