NOTE: Part number for item No. 111 varies by application. Refer to Master Parts Catalog.

NOTE: Before beginning the transmission overhaul, review the following guidelines. These general rules are provided to emphasize the need for attention to detail and care when servicing an automatic transmission.

If the transmission is being removed for major overhaul, it is important to completely clean all transmission components, including converter, cooler, cooler lines, main control valve body, governor, all clutches and all check balls after any transmission servicing that generates contamination. These contaminants are a major cause for recurring transmission troubles and must be removed from the system before the transmission is put back into service.
The cleaning of debris from the direct clutch check ball is often omitted. This omission can lead to a repeat servicing of the transmission.
Cleaning and flushing procedures for transmission components, including the direct clutch check ball, can be found under Cleaning and Inspection.
Thorough cleaning of the transmission exterior will reduce the possibility that damaging contaminants might enter the subassemblies during disassembly and assembly.
All fasteners must be tightened to the torque indicated in the text. In addition to appearing in the text, the necessary torques can be found under 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 build up 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.
When building up subassemblies or assembling the transmission, always use new gaskets and seals.
The transmission service area should be kept clean, well organized and supplied with clean lint-free shop cloths.
Whenever a seal is removed from a piston, shaft or servo, note the type of seal and when applicable, the direction of the sealing lip.
