Abstract

A transmission including a drive shaft, an output shaft, three planetary gear sets, and five shift elements, the first and second planetary gear sets are arranged in one gear plane, the first planetary gear set is a plus planetary gear set, and the second planetary gear set is a minus planetary gear set. The planetary gear sets are coupleable to one another to engage different gear ratios between the drive and output shafts. The drive shaft is connected to a sun gear of the first planetary gear set and is coupleable by the first shift element to a first element of the third planetary gear set and by the second shift element to a planetary carrier of the second planetary gear set. The third, fourth, and fifth shift elements radially encircle the planetary gear sets axially at the level the planetary gear sets and the second shift element are arranged.
