A transmission includes a main gear set, an auxiliary gear set and an electric motor with a rotor and a stator. A third shaft of the main gear set is connected to a transmission output shaft. A first shaft of the auxiliary gear set is constantly connected to the rotor. A second shaft of the auxiliary gear set is connectable through a first auxiliary shift element to a first shaft of the main gear set or a second shaft of the main gear set and through a second auxiliary shift element to a fourth shaft of the main gear set. A third shaft of the auxiliary gear set is constantly connected to the third shaft of the main gear set.
