A double clutch transmission with two clutches that have inputs connected to a drive shaft and outputs which are each connected to one of first and second transmission input shafts. Fixed gears are coupled to the input shafts and engage idler gears. Several coupling devices connect the idler gears to a respective countershaft which have an output gear that couples with an output shaft such that forward and reverse gears can be shifted. First and second dual gear planes each comprise two idler gears supported by a respective countershaft, and one fixed gear. In each of the first and the second gear planes, at least one idler gear is used for two gears. First and second single gear planes each comprise an idler gear and a fixed gear such that at least one winding-path gear can be shifted via at least one, non-engaged coupling device, assigned to one of the output gear.
