The Hydra-Matic 6T40 and similar 6T45, 6T50 and 6T30 are transversely-mounted six speed automatic transmissions produced by General Motors. The 6T40, referred to in GM inner circles as the GF6, made its debut in the 2008 Chevrolet Malibu, available with the 2.4L LE5 Ecotec engine making 164 horsepower (122 kW), and has since also be made available on the Chevrolet Cruze, Daewoo Tosca and Buick LaCrosse. It features clutch to clutch shifting, eliminating the bands used on older transmission designs. GM chose an "on-axis" design as opposed to folding the gearset behind the engine and transferring power through the use of a chain, as is used in most other GM front wheel drive transaxles. Ford also produces their own variant called the 6F35.
