It made its debut in the 2008 Chevrolet Malibu, available with the 2.4L LE5 Ecotec making 164 hp, and will also be made available on the Daewoo Tosca and Chinese-market Buick LaCrosse. The 6T45 differs from the 6T40 in its use of heavier-duty components, allowing it to handle engines with greater torque. The 6T40 will be available in front-wheel drive configuration only (MH8), but the 6T45 will be adaptable to both FWD (MH7) and all-wheel drive (MHC).
