Class5-speed longitudinalautomatic transmission

The 5L40-E (and similar 5L50) are a series of automatic transmissions made by General Motors. Designed for longitudinal engine configurations, the series includes 5 forward gears and is used in the GM Sigma platform vehicles from Cadillac, the Pontiac Solstice, BMW, and Holden Commodore.

The electronically controlled transmission is designed around a fully articulated Ravigneaux gearset that is controlled by electronically timed application of several range-specific hydraulic clutches, in combination with mechanical one-way sprag clutches. The 5L40E unit's centerpiece is an automatic overdrive which supersedes the French-made 4L30E four-speed automatic light-duty gearboxes, and like them features a torque converter clutch to eliminate slipping losses in select forward ranges. It is assembled in Strasbourg, France.
