ASSEMBLY





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

CAUTION: If the valve sticks in its bore and cannot be freed, the main control must be replaced.

NOTE: Clean the control valve body assembly 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.
