First mass produced Automatic Transmission – Hydra-Matic
We are your Cadillac transmission rebuild experts.
Parallel to the development in the 1930s of an automatically shifting gearbox was Chrysler’s work on adapting the fluid coupling to automotive use. Invented early in the 20th century. The fluid coupling was the answer to the question of how to avoid stalling the engine when the vehicle was stopped with the transmission in gear. Chrysler itself never used the fluid coupling with any of its automatic transmissions. It did use it in conjunction with a hybrid manual transmission called “Fluid Drive” (the similar Hy-Drive used a torque converter). These developments in automatic gearbox and fluid coupling technology eventually culminated in the introduction in 1939 of the General Motors Hydra-Matic. The world’s first mass-produced automatic transmission. If you bought a Cadillac in 1939, it would have had a Hydra-Matic transmission.
