    The exact procedures for rebuilding a transmission depend solely on the specific transmission as well as the problems the transmission may have. Always refer to the service manual for specific procedures for a specific transmission.

    Although the procedures vary, here are some guidelines that will help you service any transmission:

    • For the most part, torque converters are replaced. If you want to have the torque converter rebuilt, a specialist should do this.
    • All pumps, valve bodies, and cases should be checked for warpage and should be flat filed to take off any high spots or burrs prior to reassembly.
    • Keep every part absolutely clean and wipe things off only with cloths that are lint-free. The lint can collect and damage the transmission.
    • Make sure the correct size thrust washers are used throughout the transmission. Also make sure the thrust washers, bearings, and bushings are well lubricated before you install them.
    • Soak the friction plates in clean automatic transmission fluid (ATF) prior to installing them into their housing.
    • When tightening any fastener that directly or indirectly involves a rotating shaft, rotate the shaft during and after tightening to ensure the part does not bind.
    • Always use new gaskets and seals throughout the transmission.
    • Always flush out the transmission cooling system before using a rebuilt or new transmission. The cooling system is a good place for debris to collect.
