OVERVIEW
The MT82 manual transmission has 6 forward gears and a reverse. It is mounted longitudinally and has a maximum
torque capacity of 360Nm. The aluminium die-cast transmission housing is bolted to the transfer box via an aluminium
die-cast extension case.
The 6th gear ratio has been selected as an overdrive for economy and comfort at higher vehicle speeds. Optimum gear
steps ensure highly fuel-efficient utilisation of the engine torque. This 6-speed transmission provides a wide ratio spread
supporting both economy and drivability (e.g. low speed maneuvering/trailer towing).
The name MT82 is derived from the distance between the 2 shafts in the transmission:
M stands for manual
T stands for transmission
82 is the distance between the 2 shafts in milimeters (mm)
The transmission is a fill for life unit and no level check is required at service unless a leak is present.
