In addition, a second shiftable partial transmissionwith a second main shaft, which is connectable by a second group of shiftable gear pairsto the intermediate shaft, can be included. At least one shiftable gear pair of the first shiftable partial transmissionis formed by two shiftable idlers, a first of the two shiftable idlersis connectable via a shifting element A to the first main shaftand a second of the two shiftable idlersis connectable via a shifting element C to the intermediate shaft
