Abstract

A motor vehicle transmission includes: a transmission input shaft and a transmission output shaft having a transmission housing; three planetary gear sets, each of which includes the transmission elements of a sun pinion, ring gear and planet carrier for rotatably receiving at least one planet gear and which are provided with a plurality of torque transmission devices for changing a transmission ratio between the transmission input shaft and the transmission output shaft; and two spur gear stages, each having a first spur gear, which is arranged concentrically with respect to the transmission input shaft and a second spur gear, which is arranged concentrically with respect to the transmission output shaft. The second and third planetary gear sets are connected to each other by a first coupling and a second coupling. For the first coupling, one of the transmission elements of the second planetary gear set is connected to the same transmission element of the third planetary gear set. For the second coupling, a further one of the transmission elements of the second planetary gear set is connected to a further one of the transmission elements of the third planetary gear set.
