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. In addition to appearing in the article, the necessary torque measurements can be found in the General Specifications Chart.

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.
