Shift Solenoid: Testing and Inspection
Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement
1. Connect the HDS to the DLC (A).
2. Choose Shift Solenoid A, B, C, and D in the Miscellaneous Test Menu on the HDS.
NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.
3. Check that shift solenoid valves A, B, C, and D 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 the anti-theft codes for the audio system and the navigation system (if equipped).
5. Disconnect the negative terminal from the battery, then disconnect the positive terminal.
6. Remove the battery hold-down bracket, and remove the battery cover, battery, and battery tray.
7. Remove the under-hood subfuse box from its bracket, and remove the bracket from the battery base.
8. Remove the intake air duct and air cleaner housing.
9. Remove the battery base and battery base bracket.
10. Remove the nuts securing the shift cable bracket (A).
11. Remove the spring clip/washer (B) and control pin (C) then separate the shift cable end (D) from the control lever (E).
12. Check the synthetic resin bushing (F) in the shift cable end for a proper fit and wear. If the bushing is loose or worn, replace the shift cable.
13. Disconnect the transmission range switch connector (A), input shaft (mainshaft) speed sensor connector (B), output shaft (countershaft) speed
sensor connector (C), 3rd clutch transmission fluid pressure switch connector (D), and ATF temperature sensor connector (E).
