OVERVIEW
The M66EHA50 manual transmission is a 6 speed unit manufactured by Getrag-Ford in Cologne, Germany. The transmission
is a highly compact 4 shaft design, incorporating the front final drive gear, and is adapted for All W heel Drive (AW D) by
providing a connection from the final drive carrier to the Power Transfer Unit. The transmission is capable of transferring
high torque from the engine.
The transmission features two mechanical shift cables from the selector lever and an electronic reverse inhibitor.
The M66EH50 manual transmission has the following features:
380 Nm torque capacity (with torque truncation in 1st and reverse gears)
Dry weight 61 kg
Transmission oil is fill for life - 1.9L fill to level plug Oil spec MTF97309
Front differential integral with transmission
6 forward gears
4th to 6th gears and reverse gear have single cone synchronization
3rd gear is double cone synchronized
1st and 2nd gears have triple cone synchronization.
The clutch system used is a conventional single driven plate and a diaphragm spring clutch cover assembly. The clutch is
hydraulically operated by operation of the clutch pedal which disengages the drive from the engine crankshaft to the
transmission.
