This 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 will manufacture its own unique version of the transmissions in their own factories.[1][2] The 10-speed transmission was designed by Ford, while GM designed the 9-speed transmission which is used in transverse applications.[3][4]

A unique triple-clutch assembly on a dedicated intermediate shaft, placed in the middle of the architecture, replaces two ordinary clutches and is the key for packaging the 10-speed unit into the same space as previous transmissions.[5] The transmission provides small steps between each gear ratio, improving performance and maximizing engine power during acceleration. A wide gear ratio spread and a lower numerical top gear ratio reduces engine speed at vehicle highway speeds, resulting in improved efficiency.
