L322 Range Rover System Description and Operation
AUTOMATIC TRANSMISSION – ZF 5HP24
44-2-30 DESCRIPTION AND OPERATION
4th 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 input shaft gear via clutch 'A' and the planet carrier of gearset 2 via the clutch 'B'. The
planet carrier of gearset 2 is physically connected to the ring gear 3 and this drive is transmitted, via the ring gear 3
and the planet gears and carrier of gearset 3 to the output shaft, which rotates at an increased speed compared to
3rd gear.
The drive transmitted from the planet carrier of gearset 2 and the input shaft gear to planet gearset 3 results in a
complete locking of the planetary gear train. Therefore, in this condition the engine input speed is identical to the
output shaft speed creating a 1:1 output ratio.
