Abstract: A double clutch transmission comprising two clutches which each have input sides connected to a drive shaft and output sides respectively connected to one of two transmission input shafts coaxial arranged with respect to one another. At least two countershafts having toothed idler gearwheels pivotally supported thereon while toothed fixed gearwheels are disposed on the transmission input shafts and which engage with at least some of the idler gearwheels. A plurality of coupling devices are provided for coupling an idler gearwheel to the respective countershaft in a rotationally fixed manner. An output gearwheel, on each respective countershaft, is coupled to gearing of an output shaft. At least one shift element is provided for connecting two toothed gearwheels in a rotationally fixed manner such that a plurality of power shifting forward gears and at least one reverse gear can be shifted.
