  4. NOTE: Solenoids are calibrated from the factory and are not all the same. To replace a solenoid, match the replacement solenoid type (normally high/normally low) and the band number with the original solenoid or harsh/erratic shifts, harsh/soft engagement or damage to the transmission can occur.

    Number the solenoids 1 through 7 and number the main control solenoid ports 1 through 7 to correspond to the solenoid. Pull the solenoids out of the main control valve body.

  5. NOTE: Note the location of the 4 longer main control bolts for assembly.

    Remove the main control bolts from the main control.

  6. NOTE: Many components and surfaces in the main control valve body are precision machined. Use care when handling the upper and lower valve body or damage can occur to the machined surfaces.
    NOTE: The main control is positioned on the lower valve body before separating the upper valve body from the lower valve body to keep the solenoid dampers from falling out of the lower valve body.

    Position the main control on the lower valve body and separate the upper valve body from the lower valve body.

    1. Upper valve body
    2. Lower valve body

  9. NOTE: Note the location of the check balls, the relief valves and the control valve inlet nozzle for assembly.

    Remove the check balls, the relief valves and the pump inlet nozzle.

    1. Check balls
    2. Relief valves
    3. Pump inlet nozzle

  10. NOTE: Note the location of the retaining clips, caps, valves and valve springs for assembly. Failure to install the components in the correct location will result in harsh/soft or no shifts or damage to the transmission.

    Remove the retaining clips, caps, valves and valve springs from each bore of the upper and lower valve body assembly. Note the location and order of the components for assembly.

    1. Upper valve body
    2. Lower valve body

  11. NOTE: Many components and surfaces in the main control valve body are precision machined. Use care when cleaning and assembling the upper and lower valve body or damage can occur to the machined surfaces.

    Clean and inspect the upper and lower valve body for damage. Inspect the passages and valves for damage and clean any excessive debris. Install new components as necessary.

  13. NOTE: Make sure to install the retaining clips, caps, valves and valve springs in the correct locations in the upper and lower valve body or harsh/soft or no shifts or damage to the transmission can occur.
    NOTE: A clean dry valve should fall out of the clean dry valve bore under its own weight. Carefully inspect valve and bore for debris or damage if the valve does not move freely.

    Clean and install the retaining clips, caps, valves and valve springs into the bores of the upper and lower valve body.

    1. Upper valve body
    2. Lower valve body

  14. Clean and install the check balls, the relief valves and the control valve inlet nozzle in the locations they were removed from.

    1. Check balls
    2. Relief valves
    3. Pump inlet nozzle

  19. NOTE: Solenoids are calibrated from the factory and are not all the same. To replace a solenoid, match the replacement solenoid type (normally high/normally low) and the band number with the original solenoid or harsh shifts or damage to the transmission can occur.

    Inspect the solenoid O-rings for damage and install new O-rings if needed. Inspect the solenoid screens for contamination and install new solenoids if needed. If new solenoids are needed, identify which type (normally high/normally low) of solenoid it is and use the charts below to get the correct part number for the solenoid band number.

    1. O-rings
    2. Screens
    3. Solenoid band number
      Solenoid Band Number  Normally High Solenoid Part Number 
      1 BC3Z-7G383-J
      2 BC3Z-7G383-K
      3 BC3Z-7G383-L
      4 BC3Z-7G383-M
      5 BC3Z-7G383-N
      Solenoid Band Number  Normally Low Solenoid Part Number 
      1 BC3Z-7G383-R
      2 BC3Z-7G383-S
      3 BC3Z-7G383-T
      4 BBC3Z-7G383-U
      5 BC3Z-7G383-V

  21. NOTE: Make sure the solenoid retainer is installed so the bolt hole surface rests flush against the main control valve body assembly or damage to the solenoids or retainer can occur.

    Install the solenoid retainer and the bolts.

    Torque: 97 lb.in (11 Nm)
