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.
