A transmission (1) comprises a gear input shaft (2), a gear output shaft (3), several shift elements (7, 8, 9, 10, 11, 12, 13, 19), at least one planetary gearset (5) and an electrical machine (14). A required gear ratio can be adjusted as a function of the activation of the shift elements (7 to 13, 19) and the electrical machine (14). The electrical machine (14) can be linked to a first shaft (21) of the first planetary gearset (5) by way of a first shift element (12) and to a second shaft (18) of the first planetary gearset (5) by way of a second shift element (13). At least the first shift element (12) or the second shift element (13) is disposed in the axial direction of the gear input shaft (2) adjacent to the electrical machine (14).
