Shift Solenoid: Service and Repair
Shift Solenoid Valve Replacement1. Remove the drain plug (A), and drain the automatic transmission fluid (ATF).
2. Reinstall the drain plug with a new sealing washer (B).
3. Place the transmission jack under the transmission, and lift it up to create clearance between the transmission and front subframe.
4. Remove the bolt (A) securing the bracket (B) of the ATF cooler inlet line (C) on the shift solenoid valve cover (D), and remove the line bolt (E) with sealing washers (F).
5. Remove the shift solenoid valve cover (D), gasket (G), and dowel pins (H).
6. Disconnect the shift solenoid valve connectors.
7. Remove the bolts, and hold the shift solenoid valve body, then remove them. Do not hold the connector to remove.
8. Install the new O-rings (two O-rings, per a solenoid valve) (F) on the good solenoid valve. The replacement solenoid valve comes with new O-rings.
9. Install shift solenoid valves A, C, and E by holding the shift solenoid valve body; be sure to install the solenoid valves until their mounting bolt brackets contact the servo body.
NOTE: Do not install shift solenoid valve B before installing shift solenoid valve E. If solenoid valve B is installed before solenoid valve E, it may damage the hydraulic control system.
10. Install shift solenoid valve B by holding the shift solenoid valve body; be sure to install the solenoid valve until its mounting bolt bracket contacts the bracket of installed solenoid.
11. Connect the shift solenoid valve A connector (G) with the ATF temperature sensor.
12. Connect the solenoid valve B connector (ORN wire), solenoid valve C connector (GRN wire), and solenoid valve E connector (RED wire).
13. Install the shift solenoid valve cover, dowel pins, and a new gasket.
14. Install the ATF cooler inlet line with the line bolt and the new sealing washers. Create clearance with the jack between the transmission and the front subframe to tighten the line bolt to the specified torque with the torque wrench.
15. Secure the ATF cooler inlet line bracket on the shift solenoid valve cover with the bolt.
16. Check the connector for rust, dirt, or oil, then connect the connector securely.
17. Remove the transmission jack.
18. Refill the transmission with the ATF.
