A planetary gear train includes input and output shafts, first to fourth planetary gear sets respectively having first to third, fourth to sixth, seventh to ninth, and tenth to twelfth elements. The planetary gear train includes a first shaft connected with the first and fourth elements and selectively connected with the input shaft, a second shaft connected with the sixth element and selectively connected with the input shaft, a third shaft fixedly connected with the eighth and twelfth elements and the output shaft, a fourth shaft connected with the second, fifth, and seventh elements, and a fifth shaft connected with the third and eleventh elements, The planetary gear train includes a plurality of shafts each selectively connecting a corresponding element to a transmission housing, the corresponding element being an element of the third and fourth planetary gear sets that is not interconnected.

A transmission (G) for a motor vehicle includes an input shaft (GW1), an output shaft (GW2), three planetary gear sets (P1, P2, P3), and four shift elements (B1, K1, K2, K3). By selective engagement of the four shift elements (B1, K1, K2, K3) in pairs, six forward gears (1-6) are shiftable between the input shaft (GW1) and the output shaft (GW2).

A transmission between a drive aggregate and a drive output of a vehicle drivetrain has a hydrodynamic starting element and a powershiftable main transmission with a plurality of forward gears, at least one reversing gear, a transmission input, a transmission output, and frictional shifting elements. In each gear a first number of shifting elements are closed and a second number of shifting elements are open. A downstream range group has at least one interlocking shifting element which can be shifted between a first and second driving ranges. With the drive aggregate running, the vehicle at a standstill or nearly so, the main transmission in neutral, and a shift request received to change the downstream range group, shifting elements of the main transmission are actuated, thereby bracing the transmission input against a transmission housing and decoupling the transmission input from the transmission output. The downstream range group is then shifted.
