A double clutch transmission with inputs of two clutches (K1, K2) connected to a drive shaft (wan) and output sides connected to a respective transmission input shaft (w_k1 or w_k2) positioned coaxially to each other, two countershafts (w_v1, w_v2) each having toothed idler gearwheels, toothed fixed gearwheels (1, 2, 3, 4, 5, 6) are positioned in a fixed manner on the two transmission input shafts, at least one shift element (N) is provided for connecting two toothed gear wheels with one another so that a plurality of power-shiftable forward gears and a shiftable reverse gear (R1, R2) is provided. A maximum of six gear planes (7-13, 2-14, 9-15, 4-16, 5-17, 6-18) are provided so that at least one power-shiftable winding path gear (G1, R2, O1) is shiftable by the shift element (N).
