Ford–GM 10-speed automatic transmission

Motor vehicle

The Ford–GM 10-speed automatic transmission is part of a joint venture between Ford Motor Company and General Motors to design and engineer two transmissions: a longitudinal 10-speed transmission and a transverse 9-speed trans-axle. Each company manufactures its own unique version of the transmissions in its own factories.^[1]^[2] The 10-speed transmission was designed by Ford, while the 9-speed transmission was designed by GM.^[3]^[4]
