L322 Range Rover System Description and Operation
AUTOMATIC TRANSMISSION – ZF 5HP24
DESCRIPTION AND OPERATION 44-2-29
3rd Gear (D Selected)
The gear selector lever and the manual selector valve spool are in the 'D' position. Engine torque is transmitted from
the torque converter through the input shaft gear via the application of clutch 'A'. Clutch brake 'D' is applied and holds
the intermediate shaft gear stationary.
Ring gear 1 is driven by the planet gearsets 2 and 3. The torque applied to ring gear 1 is passed via the stationary
intermediate shaft gear to the planet carrier of gearset 1. The planet carrier of gearset 1 is physically connected to the
ring gear 2. This causes the planet carrier of gearset 2 to rotate at a higher speed. Because the planet carrier of
gearset 2 is physically connected to the ring gear 3, the ring gear 3 rotates in the same direction. This causes the ring
gear 3 and subsequently the planet carrier of gearset 3 and the output shaft to rotate at an increased speed compared
to 2nd gear.
