Dual clutch transmission for a motor vehicle having gear sets switchable via switching elements, which form precisely eight wheel planes (RE-1 to RE-8) disposed one after the other in axial direction from the input side to the output side of the dual clutch transmission in the sequence first to eighth, which are assigned respectively to a first sub-transmission and a second sub-transmission, of which the first sub-transmission has a first input shaft and the second sub-transmission has a second input shaft, and both sub-transmissions (A, B) have a shared output shaft, wherein the input shafts (22, 23) coaxial to one another can be alternatingly activated via in each case one load-shiftable coupling (K1, K2), and the even forward gears (2, 4, 6, 8, 10, 12) are assigned to the first sub-transmission and the odd forward gears (1, 3, 5,7, 9, 11) are assigned to the second sub-transmission, which are switchable in the case of a gear shifting via the switching elements (SE-A to SE-G), wherein at least two wheel planes (RE-1, RE-2) of the first sub-transmission have both loose gears (27, 30) on the drive side rotationally mounted on its input shaft and, meshing therewith, loose gears (28, 32) on the output side rotationally mounted on the output shaft, which is coupleable with or uncoupleable from the first input shaft and/or the output shaft by means of switching elements (SE-C, SE-F), wherein the two output-side gears (28, 32) of the two wheel planes (RE-1, RE-2) are non-rotationally disposed on an output-side hollow shaft coaxially rotationally mounted on the output shaft, which is coupleable via exactly one first switching element (SE-F) with the output shaft, and wherein the two output side gears (27, 30) of the two wheel planes (RE-1, RE-2) are coupleable via exactly one second switching element (SE-C) alternatingly with the input shaft of the first sub-transmission, characterised in that the two wheel planes (RE-1, RE-2) are disposed as the first and the second wheel plane in the first sub-transmission, and that the first sub-transmission has the third wheel plane (RE-3), which has a loose gear on the drive side rotationally mounted on the input shaft of the first sub-transmission and, meshing therewith, a loose gear on the output side rotationally mounted on the output shaft, that the output side gear of the third wheel plane (RE-3) is coupleable by means of the first switching element (SE-F) with the output shaft, and that the first switching element (SE-F) is disposed as a switching element, switchable in axial direction on both sides, between the two output side gears (32, 34) of the second and third wheel plane (RE-2, RE-3), that the drive side gear of the third wheel plane (RE-3) together with the drive side gear of the second wheel plane (RE-2) is disposed non-rotationally on a drive side hollow shaft coaxially rotationally mounted on the first input shaft, and that the first sub-transmission has the fourth wheel plane (RE-4), which has an output side gear non-rotationally disposed on the output shaft and, meshing therewith, a drive side loose gear rotationally mounted on the drive side hollow shaft, and that the drive side gear of the fourth wheel plane (RE-4) is coupleable with a third switching element (SE-D) with the drive side hollow shaft of the first sub-transmission, that the second sub-transmission has the fifth wheel plane (RE-5), which has a drive side loose gear rotationally mounted on the second input shaft and an output side loose gear rotationally mounted on the output shaft, and that the output side gear of the fifth wheel plane (RE-5) is coupleable via a fourth switching element (SE-G) with the output shaft.
