Valve Body: Service and Repair
Special Tools:
Removal
1. Disconnect the battery ground cable.
2. Raise and support the vehicle.
3. Drain the transmission fluid.
4. Remove the converter housing plug.
5. Remove the drain plug.
6. Remove the shifter cable bracket.
7. Note: Clean the area around connector to prevent contamination of the solenoid body connector.
Disconnect the transmission connector.
8. Disconnect the digital transmission range (TR) sensor connector.
9. Note: The transmission fluid pan gasket is reusable, clean and inspect for damage; if not damaged, the gasket should be reused.
Remove the transmission fluid pan and gasket.
10. Remove the transmission fluid filter.
11. Disconnect the reverse pressure switch connector.
12. Remove the reverse pressure switch and discard.
13. Remove the solenoid body.
14. Remove the valve body cover plate and gasket.
15. Remove the reverse servo.
16. Remove the manual control valve detent spring.
17. Remove the main control valve body, separator plate, and gasket.
18. Note: The intermediate clutch spring and seal will fall out of the case.
Remove the intermediate clutch spring and seal.
Installation
1. CAUTION: The intermediate clutch fluid inlet tube seal and spring must be correctly seated in the case. Failure to correctly seat the inlet tube seal and spring will cause an internal fluid leak and transmission damage.
Using a drift punch, correctly install and seat the intermediate clutch fluid inlet tube seal and spring into the case.
2. Install the special tools into the transmission case.
3. Refer to the chart for bolt locations:
4. Install the main control valve body and loosely install the screws.
5. Remove the special tools, and loosely install the screws.
6. Install the valve body cover plate and gasket and loosely install the screws.
7. Install the reverse pressure switch and loosely install the screws.
8. Tighten the screws in the sequence shown.
9. Install the reverse servo using a crisscross pattern to tighten the bolts.
10. Install the manual control valve detent spring.
11. Install new O-ring seals on the solenoid body connector. Lubricate the O-ring seals with clean MERCON (R) V Automatic Transmission Fluid XT-5-QM or equivalent meeting Ford specification MERCON (R) V.
12. CAUTION: Inspect the transmission case bore to make sure it is free of foreign material and not damaged. If it is damaged, transmission leak may occur.
Install the solenoid body. Tighten the bolts in sequence shown.
13. Connect the reverse pressure switch connector.
14. CAUTION: Lubricate the fluid filter O-ring seals with MERCON (R) V Automatic Transmission Fluid XT-5-QM or equivalent meeting Ford specification MERCON (R) V; or they may be damaged.
Note: Make sure that the fluid filter O-ring seals are correctly seated on the filter.
Lubricate the seals and install the transmission fluid filter.
15. Note: The transmission fluid pan gasket is reusable, clean and inspect for damage; if not damaged, the gasket should be reused.
Install the transmission fluid pan and gasket and loosely install the screws.
16. Using a crisscross sequence, tighten the screws.
17. Note: A new converter drain plug must be used to prevent leakage.
Install the drain plug.
18. Install the converter housing access plug.
19. Reconnect the digital TR sensor connector.
20. CAUTION: Damage will occur to the solenoid body assembly if the screw is tightened above specification.
Note: Always install new O-ring seals on vehicle harness connector.
Note: Clean the area around connector to prevent contamination of the solenoid body connector.
Note: Use petroleum jelly to lubricate the O-ring seals to aid in the installation process.
Install and lubricate new O-ring seals on the transmission connector and connect the connector.
21. Install the shift cable bracket.
22. Lower the vehicle.
23. Connect the battery ground cable.
24. Fill the transmission to the correct fluid level and check for correct transmission operation.
- Use MERCON (R) V Automatic Transmission Fluid XT-5-QM or equivalent meeting Ford specification MERCON (R) V.
