Main Control - Overhaul: Assembly

WARNING: This page is about a different car, the 2012 Ford Pickup, 2012 Ford F550 Super Duty, 2012 Ford F450 Super Duty, and 2012 Ford Cab & Chassis. However, it is still accessible from the selected car via links, so may be relevant.
    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.

    5. NOTE: Make sure to align the relief valves to the holes they rest in.
  5. Position the separator plate on the upper valve body and install the 2 bolts.
    • Tighten the bolts to 11 Nm (97 lb-in).

    9. 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.
  9. 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, use the solenoid exploded view at the beginning of this procedure to 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.
    Solenoid Band Number Normally High Solenoid Part Number

    3 BC3Z-7G383-L
    4 BC3Z-7G383-M
    5 BC3Z-7G383-N
    Solenoid Band Number Normally Low Solenoid Part Number
    2 BC3Z-7G383-S
    3 BC3Z-7G383-T
    4 BC3Z-7G383-U

    11. 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.
  11. Install the solenoid retainer and the 7 bolts.
    • Tighten to 11 Nm (97 lb-in).
