A transmission (G) for a motor vehicle. The transmission (G) has a drive shaft (GW1), an output shaft (GW2-A), first, second, third and fourth planetary gearsets (P1, P2, P3, P4) and first, second, third, fourth, fifth and sixth shift elements (B1, K1, K2, B2, K3, K4).

A modular hybrid transmission configurable between a 9-speed configuration and an 8-speed configuration includes first, second, third, and fourth planetary gear sets each having first, second, and third elements. Seven torque transmitting devices are each selectively engageable to interconnect one of the first, second, and third elements of one of the planetary gear sets directly with (i) one of the first, second, and third elements of another one of the planetary gear sets, (ii) a housing, or (iii) an input member. The seven torque transmitting devices are selectively engageable to establish nine forward speed ratios and at least one reverse speed ratio. Upon removal of a fourth torque transmitting device, the transmission is arranged in the 8-speed configuration and the remaining six torque transmitting devices are selectively engageable to establish eight forward speed ratios and at least one reverse speed ratio.

A transmission having a main transmission and a splitter group, and including at least four spur gear planes formed with a countershaft and at least five shifting elements for engaging at least six gears between the transmission input and output shafts. When shifting between gears with the highest and the second-highest gear ratios, a shift occurs in the shifting elements associated with the splitter group but not in the shifting elements associated with the main transmission, whereas when shifting between gears with the lowest and second-lowest gear ratios, a shift occurs in the shifting elements associated with the main transmission but not in the shifting elements associated with the splitter group. An electric machine can be connected by a gearset, and depending on its shift position, the gearset acts as a pre-transmission ratio for the electric machine or as a superimposition transmission.
