CAUTION: Before beginning assembly, carry out and inspect the following:
When building up subassemblies and assembling the transmission, ALWAYS use new gaskets and seals.
All fasteners must be tightened to the torque specification indicated. The necessary torques can be found in GENERAL SPECIFICATIONS .
When building up subassemblies, each component part should be lubricated with clean transmission fluid. It is also good practice to lubricate the subassemblies as they are installed in the case.

Needle bearings, thrust washers and seals should be lightly coated with petroleum jelly during subassembly buildup or transmission assembly.

Many components and surfaces in the transmission are precision machined. Careful handling during disassembly, cleaning, inspection and assembly can prevent unnecessary damage to machined surfaces.

  1. Use the special tools to install the rear case bushing if removed.
    1. Position the rear case bushing and the special tool inside the case.
