1. TECHNICAL SPECIFICATION
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.

2. PRECAUTIONS:
A. Do not lubricate the Shifter Selector Cables.
B. Ensure that the engaging gears are properly seated over their respective lugs.
C. Ensure that the Shifter finger lugs of transaxle are in line with each other while assembling the top
cover assembly.
D. Keep off the oil from clutch disc, flywheel and pressure plate surface.
E. Ensure that the oil seals are free from dust particles.
F. Use only recommended transaxle oil.
G. Do not reuse the oil seal, while assembling transaxle.
H. Lubricate drive shaft birfield and tripod joint only with grease gun as referred in manual.
I. Ensure that the boots are not damaged during assembly of driveshaft.
J. Assemble and remove the transaxle component bearings only with special tools.
