Shift Solenoid Valve Test, Replacement, and Shift Solenoid Wire Harness Replacement

WARNING: This page is about a different car, the 2013 Honda Odyssey, 2012 Honda Odyssey, and 2011 Honda Odyssey. However, it is still accessible from the selected car via links, so may be relevant.
  1. 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 (see DLC CIRCUIT TROUBLESHOOTING ).

  3. Select Shift Solenoid Valves A, B, C, and D in the Miscellaneous Test Menu with the HDS.
  4. 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 5, and test the solenoid valves.
  5. Remove the air intake scoop (see step  5 ).
  6. Do the battery removal procedure (see BATTERY REMOVAL AND INSTALLATION ).
  7. Remove the air cleaner (see AIR CLEANER ELEMENT INSPECTION/REPLACEMENT ).
  8. Remove the intake air duct (see step  10 ).
  9. Remove the main under-hood fuse box (see step  11 ).
  10. Remove the battery base (see step  12 ).
  11. Remove the spring clip (A) and the control pin (B), then separate the shift cable end (C) from the selector control lever (D).

  12. Remove the nuts securing the shift cable bracket (E).
  13. Check the bushing (F) in the shift cable end for proper fit and wear. If the bushing is loose or worn, replace the shift cable (see SHIFT CABLE REPLACEMENT  ).
  14. Disconnect these connectors:
    • A/T clutch pressure control solenoid valve A connector (A)
    • A/T clutch pressure control solenoid valve B connector (B)
    • Transmission fluid pressure switch C (4th clutch) connector (C)
    • Shift solenoid wire harness connector (D)

  15. Remove the bolt securing the harness cover (E), and remove the harness cover from its bracket (F).
  16. Remove A/T clutch pressure control solenoid valves A and B, the 8 x 102.8 mm ATF pipe (C), the 8 x 55.3 mm ATF pipes (D), and the gasket (E).

  17. Replace the gasket and the O-rings (F) with new ones when installing A/T clutch pressure control solenoid valves A and B.
  18. Remove the solenoid valve cover (A), the dowel pins (B), and the gasket (C).

  19. Replace the gasket with a new one when installing the solenoid valve cover.
  20. Disconnect the connectors from the shift solenoid valve (s) that did not click.

  21. Measure the resistance of the shift solenoid valve that was out of standard between the connector terminal and the body ground.

    Standard: 12-25Ω? 

    • If the resistance is out of the standard, go to step  24 and replace the defective shift solenoid valve.
    • If the resistance is within the standard, go to step 22 and check solenoid valve for a clicking sound.
  22. Connect a jumper wire from the negative battery terminal to body ground, and connect another jumper wire from the positive battery terminal to each solenoid valve terminal individually. A clicking sound should be heard.
    • If a clicking sound is heard, go to step 23 and replace the shift solenoid wire harness.
    • If no clicking sound is heard, go to step  24 and replace the defective shift solenoid valve.
  23. Remove the shift solenoid wire harness (A), and replace it. Install a new O-ring (B) on the shift solenoid wire harness, and install the shift solenoid wire harness in the transmission housing, then go to step  31.

  24. Remove the necessary shift solenoid valve mounting bolts, then remove the affected shift solenoid valves by holding the solenoid valve body.
    NOTE: Do not hold the shift solenoid valve connector to remove the shift solenoid valve. Be sure to hold the shift solenoid valve body.

  25. Install new O-rings (two O-rings per shift solenoid valve) (E) on the reused shift solenoid valves.
    NOTE: A new shift solenoid valve comes with new O-rings. If you install a new solenoid valve, use the O-rings provided with it.
  26. If shift solenoid valve D was replaced, install shift solenoid valve D (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 by the connector when installing the solenoid valve. Be sure to hold the solenoid valve body.
  27. If shift solenoid valve A was replaced, install shift solenoid valve A (black connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the accumulator body.
  28. If shift solenoid valve C was replaced, install shift solenoid valve C (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the bracket of shift solenoid valve A.
    NOTE: Do not install shift solenoid valve C before installing shift solenoid valve A. If shift solenoid valve C is installed before installing shift solenoid valve A, it may damage the hydraulic control system.
  29. If shift solenoid valve B was replaced, install shift solenoid valve B (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the accumulator body.
  30. Install the shift solenoid valve mounting bolts.
  31. Connect the shift solenoid valve connectors to the shift solenoid valves:
    • YEL wire connector to shift solenoid valve A.
    • RED wire connector to shift solenoid valve B.
    • GRN wire connector to shift solenoid valve C.
    • ORN wire connector to shift solenoid valve D.
  32. Install the shift solenoid valve cover, the dowel pins, and a new gasket.
  33. Install a new gasket on the solenoid valve cover, and install the 8 x 102.8 mm ATF pipe and the 8 x 55.3 ATF pipes with their filter side into the transmission housing. Install new O-rings over the ATF pipes.
  34. Install A/T clutch pressure control solenoid valves A and B.
  35. Install the harness cover on its bracket, and secure it with the bolt.
  36. Check the connectors for corrosion, dirt, or oil, and clean or repair if necessary, then connect the connectors securely.
  37. Apply molybdenum grease to the hole in the bushing in the shift cable end, then install the shift cable bracket with the nuts.
  38. Attach the shift cable end to the selector control lever, then insert the control pin into the selector control lever hole through the shift cable end, and secure the control pin with the spring clip.
  39. Install the battery base (see step  70 ).
  40. Install the main under-hood fuse box (see step  71 ).
  41. Install the intake air duct (see step  72 ).
  42. Install the air cleaner (see AIR CLEANER ELEMENT INSPECTION/REPLACEMENT ).
  43. Do the battery installation procedure (see BATTERY REMOVAL AND INSTALLATION ).
  44. Install the air intake scoop (see step  77 ).
