L322 Range Rover System Description and Operation
AUTOMATIC TRANSMISSION – ZF 5HP24
44-2-32 DESCRIPTION AND OPERATION
Reverse Gear (R Selected)
The gear selector lever and the manual selector valve spool are in the 'R' position. Engine torque is transmitted from
the torque converter to the intermediate shaft gear. The torque is applied to the intermediate shaft gear via the
application of clutch 'C'.
Clutch 'F' is applied and holds the ring gears 1 and 3 stationary and subsequently the planet carrier of gearset 2 which
is physically connected to ring gear 3.
The intermediate shaft gear drives the planet gears of gearset 1 which in turn rotate around the locked ring gear 1.
The rotation of the planet carrier of gearset 1 is transferred to the ring gear 2 to which it is physically connected. The
rotation of ring gear 2 is transferred to the planet gears of gearset 2. Because the planet carrier of gearset 2 is held
by clutch 'F', the drive is passed from the planet gears to the small gear on the input shaft gear.
The rotation is transferred via the large gear on the input shaft gear to the planet gears of gearset 3, which rotate
around the stationary ring gear 3. The rotation of the planet gears rotates the planet carrier of gearset 3 which in turn
rotates the output shaft in the reverse direction to that of the forward gears.
