Shift Solenoid: Service and Repair
Shift Solenoid Valve and Shift Solenoid Wire Harness Replacement1. Make sure you have the anti-theft code for the audio system or the navigation system (if equipped).
2. Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Remove the splash shield.
4. Remove the drain plug (A), and drain the transmission fluid (ATF).
5. Reinstall the drain plug with a new sealing washer (B).
6. Disconnect the negative terminal from the battery, then disconnect the positive terminal.
7. Remove the battery hold-down bracket, and remove the battery cover, the battery, and the battery tray.
8. Remove the battery base.
9. Remove the air cleaner housing and the intake air duct.
10. Remove the ATF dipstick, and remove the bolts securing the ATF cooler line (A).
11. Remove the harness clamp (B), and remove the ATF dipstick guide tube (C).
12. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).
13. Disconnect the shift solenoid valve connectors.
^ If replacing the shift solenoid valve(s), go to step 14.
^ If replacing the shift solenoid harness, remove the shift solenoid harness connector (A), and replace it. Install a new O-ring (B) on the shift solenoid harness connector, and install the connector in the transmission housing, then go to step 19.
14. Remove the mounting bolts, then remove the solenoid valves.
15. Install new O-rings (two O-rings per solenoid valve) (F) on the reused solenoid valves.
NOTE: A new solenoid valve comes with new O-rings. If you install a new solenoid valve, use the O-rings provided with it.
16. Install shift solenoid valve C (brown connector), shift solenoid valve D (black connector), and shift solenoid valve E (black connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the servo body.
NOTE: Do not hold the solenoid valve by the connector when installing the solenoid valve. Be sure to hold the solenoid valve body.
17. Install shift solenoid valve A (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the bracket of shift solenoid valve D.
NOTE: Do not install shift solenoid valve A before installing shift solenoid valve D. If shift solenoid valve A is installed before installing shift solenoid valve D, it may damage the hydraulic control system.
18. Install shift solenoid valve B (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the bracket of shift solenoid valve E.
NOTE: Do not install shift solenoid valve B before installing shift solenoid valve E. If shift solenoid valve B is installed before installing shift solenoid valve E, it may damage the hydraulic control system.
19. Connect the harness terminals to the solenoids:
^ RED wire connector to shift solenoid valve E.
^ GRN wire connector to shift solenoid valve C.
^ ORN wire connector to shift solenoid valve B.
^ BLU wire connector to shift solenoid valve A.
^ YEL, WHT, WHT wire connector to shift solenoid valve D.
20. Install the shift solenoid valve cover, the dowel pins, and a new gasket.
21. Install a new O-ring on the ATF dipstick guide tube, and install the guide tube then secure it with the bolts.
22. Check the connector for rust, dirt, or oil, then connect the connector securely. Install the harness clamp in its clamp bracket on the ATF dipstick guide tube.
23. Secure the ATF cooler line with the bolts.
24. Refill the transmission with ATF.
25. Install the intake air duct and the air cleaner housing.
26. Install the battery base.
27. Install the battery tray, the battery, the battery cover, and the battery hold-down bracket, then connect battery terminals.
28. Install the splash shield.
29. Enter the anti-theft code for the audio system or the navigation system (if equipped). Set the clock (on vehicles without navigation).
