Shift Solenoid: Service and Repair

Shift Solenoid Valve and Shift Solenoid Wire Harness Replacement

1. Raise the vehicle on a lift, or apply the parking brake, block rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
2. Remove the splash shield.
3. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).





4. Reinstall the drain plug with a new sealing washer (B).
5. Remove the shift solenoid valve cover (A), the dowel pins (B), the gasket (C), and the harness clamp bracket (D).





6. Disconnect the shift solenoid valve connectors.

^ If replacing shift solenoid valve(s), go to step 7.
^ If replacing the shift solenoid harness, remove the shift solenoid harness connector (A), and replace it. Install a new O-ring (B) on the new shift solenoid harness connector, and install it in the transmission housing, then go to step 12.





7. Remove the mounting bolts, then hold the shift solenoid valve body and remove the solenoid valves. Do not hold the connector to remove the solenoid valve.





8. Install new O-rings (two O-rings per solenoid valve) (E) on the solenoid valve.

NOTE: A new solenoid valve comes with new O-rings. If you install a new solenoid valve, use the O-rings provided on it.

9. Install shift solenoid valve D (black connector) and shift solenoid valve C (brown 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.

10. Install shift solenoid valve B (black connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the servo body.
11. 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 B.

NOTE: Do not install shift solenoid valve A before installing shift solenoid valve B. If shift solenoid valve A is installed before installing shift solenoid valve B, it may damage to hydraulic control system.

12. Connect the shift solenoid harness connectors:

^ BLU wire to shift solenoid valve A.
^ ORN, WHT, and WHT wires to shift solenoid valve B.
^ GRN wire to shift solenoid valve C.
^ YEL wire to shift solenoid valve D.

13. Install the shift solenoid valve cover, the dowel pins, a new gasket, and the harness clamp bracket.
14. Check the connector for rust, dirt, or oil, then connect the connector securely.
15. Refill the transmission with ATF.
16. Install the splash shield.
