Abstract: A multi step transmission, of a planetary design, which has an external housing and includes a transmission input shaft and a transmission output shaft. First, second, third and fourth planetary gear sets are each accommodated within the transmission housing along with third, fourth, fifth, sixth, seventh and eighth shafts, and at least six shift elements. The at least six shift elements comprises first and second brakes and first, second, third and fourth clutches, whose selected engagement produces different transmission ratios between the drive shaft and the output shaft such that nine separate forward gears and one reverse gear can be achieved. For each of the forward and reverse gears, only three of the six shift elements are engaged.

Torque is transmitted through the dual clutch transmission to the output shaft (Ab) by way of at least one intermediate shaft (W1, W2) that is parallel to the transmission input shafts (AW1, AW2).
