1930's video simply explains how transmissions work, simple and interesting

I had shared a couple of months back the Popular Mechanics released that showed how rear ends word. Same company (GM) produced a similar video explaining how transmissions work. This is a very simple video that puts it into layman terms and lets you see gear by gear how it's done.
I found it pretty interesting and wanted to share.

?Along with the actual wheels, the manual transmission is among the least-evolved components of a modern car. A brand-new 2015 model's stick shift has a whole lot in common with the three-speed gearbox you'd find in a car built 70 years ago. While the technology may be abidingly familiar to us enthusiasts, it can never hurt to take a refresher course in the basics. That's why we love this vintage educational film from 1936, which nicely details how our beloved human-shifted gearboxes work.
