Gearbox type Electrohydraulically controlled eight-speed planetary gearbox for all-wheel drive with torque
converter and e-machine. It also functions as a generator. During engine operation it delivers a
maximum power output of 94 kW. As a generator, it charges the hybrid battery with a charging
power of up to 80kW (refer to "Operating modes" on page 48). The separation clutch K0 for
coupling the internal combustion engine is activated electro-mechanically via a servomotor, the
separation clutch actuator V606, and therefore is independent of the gearbox hydraulics.
Control system • The hydraulic control unit and the electronic control unit are integrated in the mechatronic
module as a unit. The selector lever position is signalled electrically (shift-by-wire). The
parking lock function is electro-hydraulically actuated. The mechatronic module has the
internal ZF designation "E26/29".
• Dynamic shift program with separate sport program "S" and "tiptronic" shift program for
manual gear-shifting.
Type • Gearbox for vehicles with longitudinally-mounted engine and all-wheel drive
• Front axle drive fore of the e-machine
• Order of components: torsion damper, e-machine, converter, gear set
• Two separate oil systems: an ATF system and a gear oil system for the transfer box and front
axle drive
