Manual Transmission

The transmission consists of the following:
- A two part die cast aluminum housing
- Bevel cut gears that rotate on needle roller bearings
- An input shaft and output shaft that rotate on ball bearings
- A layshaft that rotates on roller bearings
- Selector shaft assemblies
The engine rotational torque is transmitted from the crankshaft through the clutch to the transmission input shaft, which then transmits drive to a layshaft and then the output shaft by utilizing an arrangement of gears. When reverse gear is selected, the direction of the output shaft is changed by an idler gear assembly.
In neutral, none of the gears are connected to the input or output shaft through the relevant synchronizer unit. No torque is transmitted to the driveline.
