A transmission (G) for a motor vehicle includes an input shaft (GW1), an output shaft (GW2), an electric motor (EM) which is configured for driving the input shaft (GW1) and is operable as a generator, a plurality of planetary gear sets (P1, P2, P3), and a plurality of shift elements (03, 04, 05, 14, 15). By selectively engaging the shift elements (03, 04, 05, 14, 15), various forward gears (1 to 6) between the input shaft (GW1) and the output shaft (GW2) are formable. A first shift element (04) contributes only to forming the first of the forward gears (1 to 6). By engaging the first shift element (04), a carrier (E21) of one of the planetary gear sets (P1, P2, P3) is rotationally fixable. The first shift element (04) is a friction-locking frictional shift element, friction faces of which have no friction lining and have the same surface property.
