    Very well explained.

    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.

    I'm here because someone asked me why I shift into neutral at stop lights. My answer is better gas mileage, less wasted energy and less wear. Wanted to be prepared in case someone challenges that, with a more detailed explanation. But now having watched this I think I'll just say, it's incredibly complex inside an automatic transmission but essentially you don't have one thing trying to push through fluid something else being held back refusing to move.

    Much respect to all the transmission designer engineers. They must be a genious to create something like this. And every new model has more devices in a very small piece, I remember the first FWD vehicles from GM in 1982 (Citation, Celebrity) their automatic transmission used to be very large and heavy and now, if you compare those with a 2020 automatic FWD car is less than the half part of those automatic transmissions and besides that the new ones have more speeds than the first ones (6 or 8 speeds versus 3 or four in the 80´2). It is amazing, the engineers are really a God mental health persons.

    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!

    It's all starting to make sense and this helps a lot. Figuring out how these work requires multiple passes because there's no way that most people will get it on the first pass. There's just too many things going on to get on just one pass. Each pass clears up something not understood on the previous pass. I still need to go over this a few more times till I really it, but this took me over a lot of hurdles. I'm looking to rebuild an auto trans having only rebuilt a manual so far, and those are much, much simpler compared to these and you really have to know how they work before taking them apart. So, thanks!
    And, what a brilliant, weird, convoluted design, but it does make sense eventually. These are basically analog computers, not unlike analog clocks, differentials or centrifugal clutches, constantly adapting based on user and other inputs and sensors and using valves or actuators to do it, with flowcharts very similar to computer software flowcharts.
