This is a very detailed explanation on how the gears of this automatic transmission converts the rotation of the input to those 6 speeds and reverse, using 3D animation.
I didn't explain how the real clutches works so if you are interested on that watch the video on this link: https://www.youtube.com/watch?v=TcYsV063lk8
