MMT6

Overview




MMT6 is a manual transmission based on a 3 shaft design with one input and two output shafts.
MMT6 stands for:
- Modular
- Manual
- Transmission
- 6-shift.
The transmission is intended to be part of a transverse drive line with front wheel drive. The transmission and final drive are constructed together in a common housing made of aluminum. The unique design of the transmission and final drive makes it extremely compact, yet capable of transferring high torque.
The transmission and engine have shock absorbent mountings on the side members with pendulum suspension.
The gear controls consist of the gear selector assembly, the gear selector lever with associated control arms and two mechanical gear shift cables (mechanical transmission cable for lateral travel and mechanical shift cable) which are connected to a lever each on the transmission. The mechanical transmission cable for lateral travel is adjustable. If there is a fault in, or damage to, one of the mechanical cables, both must be replaced at the same time.
The gear selector assembly is seated in rubber bushings secured to the floor of the tunnel for efficient sound insulation. The bearings for the gear selector lever in the gear selector assembly and the bearings for the outer mechanical cable controls are permanently lubricated low friction bearings.
The transmission fluid is synthetic and does not normally need to be changed. The oil is heat resistant and tolerates high loads. Fluid is topped up via the oil filler pipe. The fluid is checked via the level plug. The fluid is drained through the drain plug in the base of the transmission.
The left-hand drive shaft is secured to the final drive by a snap ring. This requires a special tool for removal.
