Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Hydramatic (also known as Hydra-Matic) was an automatic transmission developed by both General Motors' Cadillac and Oldsmobile divisions. Introduced in 1939 for the 1940 model year vehicles, the Hydramatic was the first fully automatic mass-produced transmission developed for passenger automobile use. During the 1930s, automakers sought to reduce or eliminate the need to shift gears. At the time, synchronized gear shifting was still a novelty (and confined to higher gears in most cases), and shifting a manual gearbox required more care than most drivers cared to exert. The exception here was Cadillac's break-through synchromesh fully-synchronized manual transmission, designed by Cadillac engineer Earl A. Thompson and introduced in the fall of 1928.
