Abstract
A dual-clutch transmission has two input shafts for connection to a power shift clutch, at least one countershaft offset in parallel to the input shafts, an output gearwheel designed as an idler gear and situated coaxially with respect to the countershaft, at least one gearwheel plane having an idler gear situated coaxially with respect to the countershaft, and a shifting unit having a first shift position in which the output gearwheel and the countershaft are connected to one another in a rotationally fixed manner. The shifting unit has a second shift position in which the idler gear and the output gearwheel are directly connected to one another in a rotationally fixed manner.
