The Automatic Transmission

There are some pretty amazing inventions that have shaped our daily lives. One such invention is the automatic transmission. We've all got them in our cars, but just how do they work? I found myself asking this the other day so I went on a hunt to find some videos.

This first video describes the theory from an introductory level and shows some great animations.

This next video dissects a real transmission. A real engineer demonstrates how it works with great detail.
