Main Control Valve Body: Installation

WARNING: This page is about a different car, the 2010 Mercury Milan, 2010 Lincoln MKZ, and 2010 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
  1. Connect the manual valve link and position the main control valve body in place.
    NOTE: When installing the main control valve body, place the wire harness in the open space of the separate plate, being careful not to pinch the harness. Damage to the harness will occur.

  10. Connect the transmission fluid cooler tubes to the transaxle.
    • Tighten to 10 Nm (89 lb-in).
    NOTE: Lubricate the new O-rings with clean automatic transmission fluid and install them onto the transmission fluid cooler tubes.

  14. Fill the transaxle with approximately 4.7L (5 qt) of clean transmission fluid.
  15. Install the transmission fluid fill plug.
    • Tighten to 39 Nm (29 lb-ft).

  16. With the transaxle in PARK, the vehicle on a level surface, the engine at idle (680-780 rpm) and foot pressed on the brake, move the selector lever through each gear and allow engagement of each gear. Place the selector lever back in the PARK position.
  17. Wipe the transmission fluid level indicator cap and remove the transmission fluid level indicator.
  18. Wipe the transmission fluid level indicator with a clean cloth.
  19. If transmission fluid needs to be added, add transmission fluid in 0.25L (1/2 pt) increments through the transmission fluid fill plug located on the top of the transaxle near the transmission fluid level indicator. Do not overfill the transmission fluid. Install the transmission fluid level indicator back in the transmission fluid filler tube until it is fully seated, then remove the transmission fluid level indicator. The transmission fluid level should be at the upper most mark on the transmission fluid level indicator. Only fill to the upper most mark on the transmission fluid level indicator. Do not overfill. Damage to the transaxle will occur.
    NOTE: In order to get an accurate transmission fluid level reading, the vehicle should be on a level surface. Idle the engine to reach the normal operating temperature. Using the scan tool, verify that the transaxle is at normal operating temperature 60°C-70°C (140°F-158°F), prior to adjusting the transmission fluid level.

  20. Fill the transaxle to the correct transmission fluid level.
    NOTE: The correct transmission fluid level at normal operating temperature of 60°C-70°C (140°F-158°F) is between the top 2 marks on the transmission fluid level indicator.

  21. If the TFT  is low, fill the transaxle with transmission fluid to the cold range on the transmission fluid level indicator. Recheck the transmission fluid level when the transaxle has reached the normal operating temperature.
    NOTE: The correct transmission fluid level at cool operating temperature of 15°C-25°C (59°F-77°F), is at the bottom mark on the transmission fluid level indicator.
