Abstract:
A motor vehicle transmission comprising a drive shaft, an output shaft, a planetary gear set system, and four shift elements. The first planet gear meshes with the first sun gear, first ring gear, and with one of the second planet gears. The second planet gear meshes with the second sun gear and second ring gear. The first sun gear has a smaller diameter than the second sun gear. The first ring gear has a larger diameter than the second ring gear, and is connected to the output shaft. The second ring gear is rotationally fixable by closing the first shift element. The drive shaft is connectable to the second sun gear by closing the third shift element. The drive shaft is connectable to the planet carrier by closing the fourth shift element. The first sun gear is rotationally fixable by closing the second shift element.
