Overdrive Switch: Service and Repair
O/D Switch Test/Replacement1. Remove the driver's dashboard lower cover, the instrument panel.
2. Disconnect the O/D switch/shift lock solenoid/park pin switch connector.
3. Check for continuity between the No. 5 and No. 6 terminals of the O/D switch/shift lock solenoid/park pin switch connector while pushing the O/D switch, and when the switch is released.
4. If the O/D switch is OK, connect the connector and install the removed parts. If the switch is faulty, go to step 5 for the O/D switch replacement.
5. Shift the shift lever to the R position.
6. Slide the lock tab (A) down on the shift cable and holder (B).
7. Grasp the shift cable lock (C) in the middle (D) with needle-nose pliers (E), then remove it from the shift cable end and shift cable end holder.
NOTE: Do not pry the shift cable lock with a screwdriver, it may damage the shift cable end holder.
8. Separate the shift cable end from the shift cable end holder.
9. Rotate the socket holder (A) on the shift cable (B) a quarter turn; the tab (C) on the socket holder will be in the opening (D) of the socket holder bracket (E). Then slide the holder to remove the shift cable from the socket holder bracket.
NOTE: Do not remove the shift cable by twisting the shift cable guide (F) and damper (G).
10. Remove the shift lever assembly.
11. Remove the harness from the harness clamp on the shift lever bracket base, and remove the harness band from the harness.
12. Pry the lock tabs on the back of the O/D switch/shift lock solenoid/park pin switch connector (A), and remove the lock (B).
13. Remove the terminal (C) from the connector by pushing the lock tab (D) up in the connector using a thin blade screwdriver (E). Remove all six terminals.
14. Remove the shift lever knob (A), then remove the O/D switch (B) from the knob.
15. Remove the O/D switch connector terminals by pushing the lock tabs in the connector with a thin blade screwdriver.
16. Pull the O/D switch harness wires (A) from shift lever bracket side, and remove them. Leave the harness tube (B) and remove only the wires.
17. Install the shift lever knob (A) on the shift lever (B), and align the opening (C) of the switch so it is inclined 50° (D) toward the vertical axis (E).
18. Insert the new O/D switch harness wires (A) in the original harness tube (B), then tie a string (C) around the tube to secure the terminals in the tube.
19. Pull the old tube out of the shift lever knob side to install the O/D switch harnesses.
20. Remove the old harness tube from the O/D switch harness terminals.
21. Install the O/D switch harness terminals in the new O/D switch. Either harness terminal can be installed in either cavity.
22. Install the new O/D switch in the shift lever knob.
23. Install the O/D switch harness terminals (A) in the No. 5 and No. 6 cavities. Either O/D switch harness terminal can be installed in the No. 5 and No. 6 cavities.
24. Install the park pin switch harness terminals (B) in the No. 1 and No. 2 cavities. Either park pin switch harness terminal can be installed in the No. 1 and No. 2 cavities.
25. Install the BLU harness terminal (C) of the shift lock solenoid in the No. 3 cavity, and the RED harness terminal (D) in the No. 4 cavity. Make sure that the all six terminals lock securely, then install the lock (E) securely in place.
26. Align the marks (A) on the harnesses, and tie the harness band (B) over the marks. Clamp the O/D switch harness (C) 15 mm (0.6 inch) (D) from the harness band.
27. Install the shift lever assembly.
28. Turn the ignition switch ON (II), and verify that the R position indicator comes on.
29. If necessary, push the shift cable until it stops, then release it. Pull the shift cable back one step so that the shift cable is in R. Do not hold the shift cable guide (A) to adjust the shift cable (B).
30. Turn the ignition switch OFF.
31. Insert a 6.0 mm (0.24 inch) pin (A) into the positioning holes (B) on the shift lever bracket base and through the positioning hole (C) on the shift lever. The shift lever must be in the R position.
32. Rotate the socket holder (A) on the shift cable (B) to place the tab (C) on the holder opposite of the opening (D) in the socket holder bracket (E). Align the holder with the opening in the bracket, then slide the holder into the bracket. Rotate the holder a quarter turn to secure the shift cable. Do not install the shift cable by twisting the shift cable guide (F) and damper (G).
33. Install the shift cable end (A) in the shift cable end holder (B). Keep the shift cable end and end holder free of grease.
34. Install the new shift cable lock (A) to secure the shift cable end and shift cable end holder, then push the lock tab (B) up until it stops to lock the joint.
35. Remove the 6.0 mm (0.24 inch) pin that was installed to hold the shift lever.
36. Connect the O/D switch/shift lock solenoid/park pin switch connector.
37. Move the shift lever to each gear, and verify that the A/T gear position indicator follows the transmission range switch.
38. Check that the O/D switch operates.
39. Install the instrument panel and the driver's dashboard lower cover.
