C635 Manual Transmission (Service Information): Description

The C635 6-speed transmission is a constant-mesh transmission that is synchronized in all gear ranges.

The C635 transmission is a three-shaft design to reduce overall length of the unit for easier packaging in the vehicle. Gears 1st, 2nd, 5th and 6th are on one output shaft, gears Reverse, 3rd and 4th are on the second output shaft. Each output shaft has a different final drive ratio, which is also different from most transmissions. All ratios are synchronized.

The four-plane shift mechanism is cable operated and incorporates a pull-up ring on the shift lever that must be lifted to engage reverse. This prevents unintentional selection of reverse when attempting to select 1st gear. Rubber isolation of the shift system at the transmission minimizes noise carried along the cables to the passenger compartment
