Removal
CAUTION: MERCON(R) MERCON(R)V, MERCON(R)SP, Motorcraft Premium Automatic Transmission Fluid and Motorcraft Continuously Variable Chain Type Transmission Fluid are not interchangeable transmission fluids. The use of any transmission fluid other than what is recommended for this transaxle will cause transaxle damage.
1. With the vehicle in NEUTRAL, position it on a hoist. For additional information, refer to Maintenance/Service and Repair.
2. Remove the transmission fluid drain plug and allow the transmission fluid to drain.
3. Disconnect the transmission fluid cooler tubes at the transaxle and position the tubes aside.
4. Remove and discard the transmission fluid pan bolts and remove the pan.
5. CAUTION: When removing the sealer, use care not to damage the sealing surfaces.
Remove the sealer off the fluid pan.
6. Disconnect the wire harness from the solenoids.
1 Remove the wire harness from the clamps.
^ Disconnect the 8 solenoid connectors and the 2 speed sensor connectors.
7. Remove the 2 speed sensor wires from the solenoid clamp.
8. Remove the bolt and the lock plate and pull out the transmission fluid temperature (TFT) sensor.
9. Remove the 2 bolts, suction cover and gasket.
10. Remove the 6 main control valve body bolts in the sequence shown.
11. NOTE: Be careful when removing the main control valve body, the manual control lever will fall out of its bore. Also, once all the bolts are removed, the main control valve body will fall out of the transaxle.
Remove the main control valve body.
Installation
1. CAUTION: 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.
Connect the manual valve link and position the main control valve body in place.
2. Loosely install the 6 main control valve body bolts in the sequence shown.
3. Install the suction cover gasket, cover and loosely install the 2 bolts.
4. Tighten the 8 bolts to 10 Nm (89 lb-in) in the sequence shown.
5. Lubricate the O-ring and install the TFT sensor.
^ Tighten to 10 Nm (89 lb-in).
6. Connect the 2 speed sensor wires.
7. Connect the wire harness to the solenoids.
1 Install the wire harness into the clamps.
^ Connect the 8 solenoid connectors and the 2 speed sensor connectors.
8. Install a bead of sealer to the fluid pan.
9. Using new pan bolts, install the fluid pan.
^ Tighten to 13 Nm (10 lb-ft).
10. NOTE: Lubricate the new O-rings with clean automatic transmission fluid and install them onto the transmission fluid cooler tubes.
Connect the transmission fluid cooler tubes to the transaxle.
^ Tighten to 10 Nm (89 lb-in).
11. Install the transmission fluid drain plug.
^ Tighten to 47 Nm (35 lb-ft).
12. Remove the transmission fluid fill plug.
13. Fill the transaxle with approximately 4.7L (5 qt) of clean transmission fluid.
14. Install the transmission fluid fill plug.
^ Tighten to 39 Nm (29 lb-ft).
15. 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.
16. Wipe the transmission fluid level indicator cap and remove the transmission fluid level indicator.
17. Wipe the transmission fluid level indicator with a clean cloth.
18. 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.
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.
19. 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.
Fill the transaxle to the correct transmission fluid level.
20. 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.
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.
