LR3/Disco 3
The ZF S6-53 all synchromesh transmission has six forward gears and a reverse. It is mounted longitudinally and has a
maximum torque capacity of 472Nm. The aluminium die-cast front housing is bolted to the front of the transmission and
the DD295 transfer box is mounted at the rear.
The sixth gear has been set up as an economic overdrive to ensure comfortable travel at higher vehicle speeds. Optimum
gear steps ensure highly fuel-efficient utilisation of the engine torque.
The idler gears of the 1st, 2nd, 6th and reverse gears are located on the main shaft, while the 3rd and 4th gears are
located on the layshaft. The mating gears are solidly attached to the opposite shaft. Changing direction, via the reverse
gear, is achieved with the assistance of an intermediate gear situated between the layshaft and main shaft. The layshaft
and main shaft are hollow to reduce weight.
The transmission is a fill for life unit and no level check is required at service unless a leak is present.
