Torque Converter Clutch Solenoid: Testing and Inspection
Shift Solenoid Valve A, B, and C, Torque Converter Clutch Solenoid Valve Test/Replacement1. Connect the HDS to the DLC (A).
2. Choose Shift Solenoid A, B, C, and Lockup Solenoid Test in the Miscellaneous Test Menu on the HDS.
3. Check that shift solenoid valve A, B, C, and the torque converter clutch solenoid valve 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 4, and test the solenoid valves.
4. Make sure you have anti-theft codes for the audio system and the navigation system (if equipped), then write down the audio presets.
5. Disconnect the negative terminal from the battery, then disconnect the positive terminal.
6. Remove the battery hold-down bracket, and remove the battery and battery tray.
7. Remove the intake manifold cover and the intake air duct.
8. Remove the battery base and battery base bracket.
9. Remove the nuts securing the shift cable bracket (A).
10. Remove the spring clip/washer (B) and control pin (C), then separate the shift cable end (D) from the control lever (E).
11. Check the bushing (F) in the shift cable end for a proper fit and wear. If the bushing is loose or worn, replace the shift cable.
12. Remove the bolt securing the harness cover (A).
13. Remove the harness clamp (B) from the harness cover/clamp bracket (C), disconnect the 4th clutch transmission fluid pressure switch connector (D), then remove the harness cover from the bracket.
14. Disconnect the A/T clutch pressure control solenoid valve A connector (E), A/T clutch pressure control solenoid valve B connector (F), solenoid harness connector, transmission range switch connector, ATF temperature sensor connector, output shaft (countershaft) speed sensor connector, input shaft (mainshaft) speed sensor connector, and 3rd clutch transmission fluid pressure switch connector.
15. Remove A/T clutch pressure control solenoid valves A and B, ATF pipes (C), and gasket (D).
16. Replace the gasket and O-rings (E) with new ones when installing A/T clutch pressure control solenoid valves A and B.
17. Remove the solenoid valve cover (A), dowel pins (B), and gasket (C).
18. Replace the gasket with a new one when installing the solenoid cover.
19. Disconnect shift solenoid valve A connector (A), shift solenoid valve B connector (B), shift solenoid valve C connector (C), and torque converter clutch solenoid valve connector (D).
20. Measure the resistance of each solenoid valve between the connector terminal and body ground.
Standard: 12 - 25 ohms
^ Replace the solenoid valve if the resistance is out of standard.
^ If the resistance is within the standard, go to step 21.
21. Connect the negative battery terminal to body ground, and connect the positive battery terminal to each solenoid valve terminal individually.
^ If a clicking sound is heard, go to step 22 and replace the solenoid harness.
^ If no clicking sound is heard, go to step 23 and replace the shift solenoid valve.
22. Remove the solenoid harness connector (A), and replace it. Install a new O-ring (B) on the solenoid harness connector, and install the connector in the transmission housing, then go to step 29.
23. Remove the mounting bolts, then remove the solenoid valves.
24. Install new O-rings (two O-rings per solenoid valve) (E) on each 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 on it.
25. Install shift solenoid valve B (black connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the accumulator body.
NOTE: Do not hold the solenoid valve connector to install the solenoid valve. Be sure to hold the solenoid valve body.
26. Install torque converter clutch solenoid valve (D) (black connector) by holding the solenoid valve body; make sure the mounting bracket contacts the accumulator body.
27. Install shift solenoid valve C (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the bracket of torque converter clutch solenoid valve.
NOTE: Do not install shift solenoid valve C before installing torque converter clutch solenoid valve. If shift solenoid valve C is installed before installing torque converter clutch solenoid valve, it may damage to hydraulic control system.
28. Install shift solenoid valve A (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the accumulator body.
29. Connect the harness terminals to the solenoids:
^ RED wire connector to shift solenoid valve A.
^ ORN wire connector to shift solenoid valve B.
^ GRN wire connector to shift solenoid valve C.
^ YEL wire connector to the torque converter clutch solenoid valve.
30. Install the shift solenoid valve cover, dowel pins, and a new gasket.
31. Install the new solenoid valve body gasket on the solenoid valve cover, and install the ATF pipes with the filter end in the transmission housing. Install new O-rings over the ATF pipes.
32. Install A/T clutch pressure control solenoid valves A and B.
33. Install the harness cover on the cover bracket, and secure it with the bolt.
34. Check the connectors for rust, dirt, or oil, clean or repair if necessary, then connect the connectors securely. Install the harness clamp on the bracket.
35. Apply molybdenum grease to the hole in the bushing in the cable end. Attach the shift cable end to the control lever, then ,insert the control pin into the control lever hole through the shift cable end, and secure the control pin with the spring clip/washer.
36. Secure the shift cable bracket with the nuts.
37. Install the battery base bracket and battery base.
38. Install the intake air duct and the intake manifold cover.
39. Install the battery tray, battery, and battery hold down bracket, then connect the battery terminals.
40. Enter the anti-theft codes for the audio system and the navigation system (if equipped), then enter the audio presets. Set the clock (on vehicles without navigation).
41. Do the power window control unit reset procedure.
