retro 1936 video chevrolet auto mechanics spinning gears

In yet another retro edition of ForceGT, we present “Spinning Levers” – a training video from the 1930’s which brilliantly explains transmission fundamentals.

The educational video was produced by Jam Handy on behalf of Chevrolet. It begins with a simplistic understanding of how a lever works and progressively increases the complexity of their models. Initially the basics are covered; eventually Jam explores the concept behind multi-speed and synchro-mesh gearing.
