A transmission device for a motor vehicle includes a planetary gearset and a spur gear differential. The planetary gearset includes a drive sun gear, a ring gear fixed to the housing, and multiple stepped planetary gears. Each stepped planetary gear has a first gear meshing with the drive sun gear and a second gear meshing with the ring gear. The spur gear differential includes multiple first and second compensation gears. Each first compensation gear meshes with a first output sun gear, each second compensation gear meshes with a second output sun gear, and the first and second compensation gears mesh with each other in pairs. One compensation gear of each compensation gear pair is arranged in phase with a respective stepped planetary gear. The other compensation gear of each compensation gear pair overlaps axially and contactlessly with the second gear.

A front-rear wheel driving force distribution device includes a center differential and a limited slip differential. The limited slip differential includes a first clutch, a second clutch, a first piston, a second piston, and a one-way clutch provided between the first clutch and a rear propeller shaft.
