Shift Solenoid Valve Test
Shift Solenoid Valve Test1. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
2. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting.
3. Select Shift Solenoid Valves A, B, C, D, and E in the Miscellaneous Test Menu on the HDS.
4. Check that shift solenoid valves A, B, C, D, and E operate with the HDS. A clicking sound should be heard.
^ If a clicking sound is heard, the valves are OK. The test is complete, disconnect the HDS.
^ If no clicking sound is heard, go to step 5.
5. 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.
6. Remove the splash shield.
7. Disconnect the shift solenoid wire harness connector.
8. Measure the resistance:
^ No. 1 terminal: Shift solenoid valve C
^ No. 2 terminal: Shift solenoid valve B
^ No. 3 terminal: Shift solenoid valve E
^ No. 5 terminal: Shift solenoid valve A
^ No. 8 terminal: Shift solenoid valve D
Standard: 12 - 25 ohms
^ If the resistance is within the standard, go to step 9.
^ If the resistance is out of standard, go to step 10.
9. Connect a jumper wire from the battery positive terminal to each shift solenoid wire harness connector terminal individually. A clicking sound should be heard.
^ If a clicking sound is heard, the valves are OK. The test is complete, reconnect the connector.
^ If no clicking sound is heard, go to step 10.
10. Remove the drain plug (A), and drain the transmission fluid (ATF).
11. Reinstall the drain plug with a new sealing washer (B).
12. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).
13. Disconnect the shift solenoid valve connectors.
14. Measure the resistance of each shift solenoid valve between the connector terminals and body ground:
Standard: 12 - 25 ohms
^ If the resistance is within the standard, go to step 15.
^ If the resistance is out of standard, go to step 17.
15. Connect a jumper wire from the positive battery terminal to each shift solenoid valve terminal individually.
^ If a clicking sound is heard, go to step 16.
^ If no clicking sound is heard, go to step 17.
16. Disconnect the shift solenoid wire harness connector (A), and remove the bolt securing the shift solenoid wire harness (B). Install a new O-ring (C) on a new shift solenoid wire harness, and install the shift solenoid wire harness in the transmission housing. Then go to step 22.
17. Remove the mounting bolts (F), then hold the shift solenoid valve body, and remove the shift solenoid valves. Do not hold the connector to remove the shift solenoid valves.
18. Install new O-rings (two O-rings per shift solenoid valve) (G) on the shift solenoid valves.
NOTE: A new shift solenoid valve comes with new O-rings. If you install a new shift solenoid valve, use the O-rings provided with it.
19. 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 shift solenoid valve connector to install the shift solenoid valve. Be sure to hold the shift solenoid valve body.
20. 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.
21. 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.
22. Connect the shift solenoid harness terminals to the shift solenoid valves:
^ 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.
23. Install a new gasket, the dowel pins, and the shift solenoid valve cover.
24. Refill the transmission with ATF.
25. Install the splash shield.
