Front Planetary Gear Set
The planetary carrier (13) and sun gear (21) are connected via the engaged driving clutch K1 (7). The planetary
gearset is therefore blocked and turns as a closed unit at the input speed due to the mechanical connection of the
annulus gear (8) and driveshaft (25).
Center Planetary Gear Set
The annulus gear (10) is driven at the same speed as the rear planetary carrier (15) as a result of a mechanical
connection. The sun gear (22) is held against the housing by the multi-disc holding clutch B2 (6). The planetary
pinion gears (18) turn on the fixed sun gear (22) and increase the torque from the annulus gear (10) to the plan-
etary carrier (14). The output shaft (26) connected to the planetary carrier (14) turns at a reduced speed in the
running direction of the engine.
Rear Planetary Gear Set
The annulus gear (11) turns at the input speed as a result of the mechanical connection to the front planetary carrier
(13). The sun gear (23) is held against the housing by the engaged multi-disc holding clutch B2 (6), by the locked
freewheel F2 (24) during acceleration and by the engaged driving clutch K3 (12) during deceleration. The rear plan-
etary pinion gears (19) turn on the fixed sun gear (23) and increase the torque from the annulus gear (11) to the
planetary carrier (15). The planetary carrier (15) moves at a reduced speed in the running direction of the engine.
THIRD GEAR POWERFLOW
Torque from the torque converter is increased via the driveshaft (25) and the center planetary gearset and trans-
ferred to the output shaft (26).
