Manual Transmission

The M50D is a top-shifted, fully synchronized, five speed manual transmission, equipped with an overdrive fifth gear ratio. All gear changes are accomplished with synchronizer sleeves.
The case, case cover and extension housing are constructed of aluminum alloy. Steel bearing race inserts provide durability in appropriate areas. The extension housing contains a bronze alloy bushing that can not be replaced. The extension housing must be replaced if the bushing is damaged.
