L322 Range Rover System Description and Operation
AUTOMATIC TRANSMISSION – ZF 5HP24
44-2-28 DESCRIPTION AND OPERATION
2nd 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 to the planet gearset 3. The torque is applied to the input shaft gear via the application of clutch
'A'.
The clutch 'E' is applied which locks the planet carrier of gearset 1. The planet carrier is physically connected to the
ring gear 2 which is subsequently also locked.
The small diameter input shaft gear drives the planet gears of gearset 2, which rotate around the stationary ring gear
2 in the direction of engine rotation. The planet carrier of gearset 2 is physically connected to the ring gear 3 which
subsequently rotates in the same direction. The rotation of the ring gear 3 is transmitted to the planet gearset 3, which
rotates around the large diameter gear of the input shaft gear. The rotation is passed via the planet carrier of gearset
3 to the output shaft which rotates at an increased speed compared to 1st gear.
