A/T Clutch Pressure Control Solenoid Valve A Test
A/T Clutch Pressure Control Solenoid Valve A Test1. Connect the HDS to the DLC (A) located under the driver's side of the dashboard.
2. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting.
3. Select Clutch Pressure Control (Linear) Solenoid Valve A in the Miscellaneous Test Menu on the HDS.
4. Test A/T clutch pressure control solenoid valve A with the HDS.
^ If the valve tests OK, the test is complete. Disconnect the HDS.
^ If the valve does not test OK, follow the instructions on the HDS.
^ If the valve does not test OK, and the HDS does not determine the cause, go to step 5.
5. Make sure you have the anti-theft code for the audio system and the navigation system (if equipped).
6. Disconnect the negative cable from the battery, then disconnect the positive cable.
7. Remove the battery hold-down bracket, the battery, and the battery tray.
8. Remove the engine cover and the air cleaner assembly.
9. Remove the battery base.
10. Disconnect the A/T clutch pressure control solenoid valve A connector.
11. Measure A/T clutch pressure control solenoid valve A resistance at the connector terminals.
Standard: 3 - 10 ohms
^ If the resistance is out of standard, replace A/T clutch pressure control solenoid valve A.
^ If the resistance is within the standard, go to step 12.
12. Connect the negative battery terminal to solenoid valve A connector terminal No. 2, and connect the positive battery terminal to the connector terminal No. 1.
^ If a clicking sound is heard, the valve is OK. Reconnect the connector, and install all removed parts.
^ If no clicking sound is heard, go to step 13.
13. Remove the nuts securing the shift cable bracket (A).
14. Remove the spring clip (B) and the control pin (C), then separate the shift cable end (D) from the control lever (E).
15. Remove the bolt securing the harness cover (A).
16. Remove the harness cover/clamp bracket (B), disconnect the 4th clutch transmission fluid pressure switch connector (C), then remove the harness cover from the bracket.
17. Disconnect the A/T clutch pressure control solenoid valve A connector (D), the A/T clutch pressure control solenoid valve B connector (E), the shift solenoid harness connector, the transmission range switch connector, the ATF temperature sensor connector, the output shaft (countershaft) speed sensor connector, the input shaft (mainshaft) speed sensor connector, and the 3rd clutch transmission fluid pressure switch connector.
18. Remove A/T clutch pressure control solenoid valves A and B, the ATF pipes (C), the gasket (D), and the O-rings (E). Note the lengths and locations of the ATF pipes.
19. Check the fluid passage of the solenoid valve for contamination.
20. Connect the negative battery terminal to A/T clutch pressure control solenoid valve A connector terminal No. 2, and connect the positive battery terminal to the connector terminal No. 1. Make sure A/T clutch pressure control solenoid valve A moves.
21. Disconnect one of the battery terminals and check valve movement at the fluid passage in the valve body mounting surface. If the valve binds or moves sluggishly, or if the solenoid valve does not operate, replace A/T clutch pressure control solenoid valves A and B.
22. Clean the mounting surfaces and fluid passages of the solenoid valve body and the solenoid valve cover.
23. Install a 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.
24. Install A/T clutch pressure control solenoid valves A and B.
25. Install the harness cover on the cover bracket, and secure it with the bolt.
26. 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.
27. Apply molybdenum grease to the hole in the bushing in the shift 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.
28. Secure the shift cable bracket with the nuts.
29. Install the battery base.
30. Install the air cleaner assembly and the engine cover.
31. Install the battery tray, the battery, and the battery hold-down bracket, then connect the battery cables.
32. Enter the anti-theft code for the audio system and the navigation system (if equipped). Set the clock (on vehicles without navigation).
