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 fluid other than what is recommended for this transmission will cause transmission damage.
1. With the vehicle in NEUTRAL, position it on a hoist.
2. Remove the transmission fluid drain plug and allow the fluid to drain.
3. Disconnect the transmission fluid cooler tubes at the transaxle.
4. Disconnect the transmission fluid cooler tube bracket and position the tubes aside.
5. Remove the transmission fluid pan bolts and remove the pan.
6. CAUTION: When removing the sealer, use care not to damage the sealing surface.
Remove the sealer off the fluid pan.
7. 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.
8. Remove the 2 speed sensor wires from the solenoid clamp.
9. Remove the bolt and the lock plate and pull out the transmission fluid temperature (TFT) sensor.
10. Remove the 2 bolts, suction cover and gasket.
11. Remove the 6 main control valve body bolts in the sequence shown.
12. 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.
3. Install the suction cover gasket, cover and loosely install the 2 bolts.
4. Tighten the 8 bolts to 10 Nm (89 inch lbs.) in the sequence shown.
5. Lubricate the O-ring and install the transmission fluid temperature sensor.
^ Tighten to 10 Nm (89 inch lbs.).
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. Install the fluid pan.
^ Tighten to 13 Nm (10 ft. lbs.).
10. NOTE: Lubricate the new O-rings with clean automatic transmission fluid and install them onto the fluid cooler tubes.
Connect the transmission fluid cooler tubes to the transaxle.
^ Tighten to 10 Nm (89 inch lbs.).
11. Connect the transmission fluid cooler tube bracket to the transaxle.
^ Tighten to 10 Nm (89 inch lbs.).
12. Install the transmission fluid drain plug.
^ Tighten to 47 Nm (35 ft. lbs.).
13. Remove the transmission fluid fill plug.
14. Fill the transaxle with approximately 4.7L (5 quarts) of clean automatic transmission fluid.
15. Install the fluid fill plug.
^ Tighten to 39 Nm (29 ft. lbs.).
16. With the transaxle in (P) PARK, the vehicle should be on a level surface, the engine at idle (680 - 780 rpm), 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 fluid level indicator cap and remove the fluid level indicator.
18. Wipe the fluid level indicator with a clean cloth.
19. NOTE: In order to get an accurate fluid level reading, the vehicle should be on a level surface, the engine at idle (680 - 780 rpm) for 5 minutes and the fluid temperature should be at least 70 degrees C - 80 degrees C (158 degrees F - 176 degrees F) using the scan tool.
If fluid needs to be added, add fluid in 0.25L (1/2 pint) increments through the fluid fill plug located on the top of the transaxle near the fluid level indicator. Do not overfill the fluid. Install the fluid level indicator back in the fluid filler tube until it is fully seated, then remove the indicator. The fluid level should be at the upper-most mark on the fluid level indicator. Only fill to the upper-most mark on the fluid indicator. Do not overfill. Damage to the transaxle will occur.
