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 is produced at the GM Powertrain plant in Strasbourg, France. The 6L50 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 6L45 version is totally dedicated to BMW applications, either RWD or AWD.
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).
