Today, GM uses a simple naming scheme for their transmissions, with the "Hydra-Matic" name used on most automatics across all divisions.įirst-generation longitudinal (Rear Wheel drive) Most early electronic transmissions use the "-E" designator to differentiate them from their non-electronic cousins, but this has been dropped on transmissions with no mechanical version like the new GM 6L80 transmission. The next-generation transmissions, introduced in the early 1990s, were the electronic Hydra-Matics based on the Turbo-Hydramatic design. Also manufactured and used by Holden as the Trimatic transmission. A third variant was the light-duty rear wheel drive Turbo-Hydramatic 180 used in many European models. The basic rear-wheel drive Turbo-Hydramatic spawned two front-wheel drive variants, the transverse Turbo-Hydramatic 125, and the longitudinal Turbo-Hydramatic 425. The Turbo-Hydramatic was used by all GM divisions, and formed the basis for the company's modern Hydramatic line.

Through the 1950s, all makers were working on their own automatic transmission, with four more developed inside GM alone. The GM Hydra-Matic was a success and installed in the majority of GM models by 1950.
