Main Control Valve Body: Assembly

    CAUTION: Do not lose parts when cleaning or servicing.
  1. Thoroughly clean all parts in solvent and blow dry with moisture free compressed air.
  2. CAUTION: Do not stone, file or sand the valves. This will remove the anodized finish and may result in further main control or transmission damage.
  3. After cleaning the main control valve body, carry out the following:
    • Inspect all valve and plug bores for scoring or burrs.
    • Check all fluid passages for obstructions.
    • Inspect all valves and plugs for burrs.
    • Inspect all mating surfaces for burrs or distortion.
    • Inspect all springs for distortion.
    • Check all valves and plugs for free movement in their respective bores.
      • Valves and plugs, when dry, must fall from their own weight into their respective bores.
    • Roll the manual valve on a flat surface to check for a bent condition.
  4. Clean and inspect the EPC solenoid screens.
