A double clutch transmission with two clutches whose input sides are connected to a drive shaft and whose output sides are each connected to one of two transmission input shafts arranged coaxially with respect to one another. At least two countershafts are provided on which toothed idler gearwheels are rotatably supported, and toothed fixed gearwheels are positioned on the two transmission input shafts in a rotationally fixed manner such that it is possible to shift at least a plurality of power shiftable forward gears and at least one reverse gear. A maximum of six gear planes are provided so that at least one winding path gear is shiftable when a coupling device of the second countershaft, associated with the output gear, is disengaged.
