Ford-GM 10-speed automatic transmission

This transmission is part of a joint-venture between General Motors and Ford Motor Company to split development of two transmissions, a longitudinal 10-speed and a transverse 9-speed. As part of their joint-venture, Ford will let GM use Ford's 10-speed transmission, with rights to modify and manufacture it for their own applications. In-exchange for Ford's 10-speed transmission, General Motors will let Ford use GM's 9-speed transmission for front-wheel drive applications. [1][2]

The improved performance is the result of smaller steps between each ratio, maximizing engine power under acceleration, while a wide 7.39 overall gear ratio spread and a lower numerical top gear ratio results in improved efficiency by reducing engine revolutions at highway speeds.
