Abstract

A transmission (G) for a motor vehicle includes a drive shaft (GW1), an output shaft (GW2), a first and a second planetary gear set (P1, P2), and a first, second, third, fourth and fifth shift element (04, 13, 14, 26, 36). Six forward gear ratios (1-6) between the drive shaft (GW1) and the output shaft (GW2) are engagable through selective pairwise closure of the five shift elements (04, 13, 14, 26, 36) and rotationally fixed immobilization of the sun gear (E11) of the first planetary gear set (P1).
