A gearbox module having a gearbox input and at least one gearbox output; having a starting element coupled to the gearbox input, having an input and an output that can be coupled at least indirectly to the gearbox output; having a gear-shifting device, having at least two inputs and one output, which can be connected to the gearbox output; a first input of the gear-shifting device is connected to the output of the starting element and a second input is connected to the input of the starting element; each input of the gear-shifting device is selectively connected by means of a synchronously shiftable coupling, thereby producing a first power branch and a second power branch.
