GM 6L50 transmission

The 6L50 (and similar 6L45) is a 6-speed longitudinally-mounted automatic transmission produced by General Motors. It is very similar in design to the larger 6L80/6L90, and will be produced at the GM Powertrain plant in Strasbourg, France. It will debut for the 2007 model year on the V8-powered versions of the Cadillac STS sedan and Cadillac SRX crossover, and will eventually replace the 5L40-E and 5L50 in GM's lineup.

The 6L50 is adaptable to rear-wheel drive and all-wheel drive applications. It can accommodate engines with up to 332 ft·lbf (450 N·m) of torque, and vehicles with a GVWR of 5,000 lb (2,268 kg).
