FIRST GEAR POWERFLOW
Torque from the torque converter is increased via the driveshaft (25) and all three planetary gearsets and trans-
ferred to the output shaft (26).
Front Planetary Gear Set
The annulus gear (8) is driven by the driveshaft (25). The sun gear (21) is held against the housing by the locked
freewheel F1 (20) during acceleration and via the engaged multi-disc holding clutch B1 (4) during deceleration. The
planetary pinion gears (17) turn on the fixed sun gear (21) and increase the torque from the annulus gear (8) to the
planetary carrier (13). The planetary carrier (13) moves at a reduced speed in the running direction of the engine.
