L322 Range Rover System Description and Operation
AUTOMATIC TRANSMISSION – ZF 5HP24
DESCRIPTION AND OPERATION 44-2-31
5th 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 carrier of gearset 2 via the application of clutch 'B'. Clutch 'D' is applied to lock the
intermediate shaft gear.
The planet carrier of gear 2 is physically connected to the ring gears 1 and 3 and drives them at the same speed. The
rotation of ring gear 1 is passed to the planet gears of gearset 1 which rotate around the locked intermediate shaft
gear. The rotation of the planet gears is passed through the planet carrier of gearset 1 to the ring gear 2, to which it
is physically connected.
The rotation of the ring gear 2 is passed to the planet gears of gearset 2 which in turn rotates the small diameter gear
of the input shaft gear. This rotation is then passed, via the larger diameter gear of the input shaft gear, to the planet
gears of gearset 3 in the direction of engine rotation.
This rotation of the planet gears of gearset 3 increases the rotational speed of the planet carrier of gearset 3 and
subsequently drives the output shaft at an increased speed compared to 4th gear.
