Abstract: A transmission (G) for a motor vehicle. The transmission (G) comprises a transmission input (GW1-A), a transmission output (GW2-A), first, second, third and fourth planetary gearsets (P1, P2, P3, P4) and first, second, third, fourth, fifth and sixth shift elements (B1, B2, K1, K2, K3, K4). Ten forward gears and one reverse gear can be achieved between the transmission input (GW1-A) and the transmission output (GW2-A) by selectively operating the six shift elements (B1, B2, K1, K2, K3, K4). A drive train for a motor vehicle having such a transmission (G) is also disclosed.

Abstract: A transmission (G) for a motor vehicle which has a transmission input (GW1-A), a transmission output (GW2-A), five planetary gear sets (P1, P2, P3, P4, P5) and six shifting elements (B1, B2, K1, K2, K3, B3). By selectively actuating the six shifting elements (B1, B2, K1, K2, K3, B3), ten forward gears and one reverse gear can be selected between the transmission input (GW1-A) and the transmission output (GW2-A). Further, the drive train is typically incorporated into a motor vehicle.

Abstract: A variator unit of a power-split continuously variable transmission device is fixed to a rotationally fixed component and has a primary side rotationally fixed to an input shaft and a secondary side rotationally fixed to each respective first element of the first and a second planetary gear sets via a third shaft. A third element of the first planetary gear set is rotationally fixed to a third element of the second planetary gear set via a fourth shaft and is fixable to the rotationally fixed component via a first shift element. A fifth shaft is rotationally fixed to a second element of the second planetary gear set, which is fixable to the rotationally fixed component via the third shift element, and is connectable to the input shaft via the second shift element. A second element of the first planetary gear set is rotationally fixed to the output shaft.
