Main Control Valve Body: Assembly

WARNING: Air pressure must not exceed 1.38 bar (20 psi). Wear safety glasses when using compressed air. Failure to follow these instructions may result in personal injury.

CAUTION: If the valve sticks in its bore and cannot be freed, install a new main control valve body.

NOTE: Clean the main control valve body and accumulator body assembly of the main control in cleaning solvent. Blow dry with moisture-free regulated compressed air. The solenoid valve body should not be cleaned in cleaning solvent. It may be blown clean with compressed air or wiped clean with a lint-free cloth.

Install a new intermediate and overdrive accumulator plug seal and coat with petroleum jelly. See Figure.

CAUTION: Do not install the intermediate and overdrive accumulator valve plug and seal too far into the bore and damage the seal. Only push the intermediate and overdrive accumulator valve plug until it is flush with the accumulator body assembly.
