The direct shift transmission is actually made up of two mutually independent transmissions. There is a multi-disc clutch assigned to each of these transmissions. The left-hand duplex clutch runs in the DST oil. Gears 1, 3, 5 and reverse are shifted via multi-disc clutch K1. Gears 2, 4, 6 are shifted via clutch K2. The right-hand duplex clutch is made up of two conventional dry clutches combined to form a duplex clutch. Clutches K1 and K2 can be actuated in both duplex clutches. Thanks to the respective colour-coding the force transmission can be followed and understood.
