A/T Shift Solenoid Valve Test

1.Connect the HDS to the DLC (A).

 

2.Choose Shift Solenoid A, B, C, and D Test in Miscellaneous Test Menu with the HDS.

NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.

3.Check that the shift solenoid valve 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 4, and test the solenoid valve.

4.Lift the vehicle up on a hoist, or apply the parking brake, block the rear wheels, and raise the front of the vehicle. Make sure it is securely supported.

5.Remove the splash shield.

6.Disconnect the shift solenoid harness connector.

 

7.Measure shift solenoid valve resistance between shift solenoid harness connector terminals below and body ground:

  • No. 1: shift solenoid valve C
  • No. 2: shift solenoid valve B
  • No. 5: shift solenoid valve A
  • No. 8: shift solenoid valve D

Standard: 12-25 W 

  • If the resistance is within the standard, go to 8 and check solenoid valve for a clicking sound.
  • If the resistance is out of standard, go to 9.

8.Connect the battery positive terminal to the shift solenoid harness connector terminals, and connect the battery negative terminal to body ground individually. A clicking sound should be heard.

9.Remove the drain plug (A), and drain the automatic transmission fluid (ATF).

 

10.Reinstall the drain plug with a new sealing washer (B).

11.Remove the shift solenoid valve cover (A), dowel pins (B), gasket (C), and harness clamp bracket (D).

 

12.Disconnect the connectors from shift solenoid valve A, shift solenoid valve B, shift solenoid valve C, and shift solenoid valve D.

 

13.Measure the resistance of each solenoid valve between the connector terminal and body ground.

Standard: 12-25 W 

  • If the resistance is out of standard, go to 16 and replace shift solenoid valve.
  • If the resistance is within the standard, go to 14 and check solenoid valve for a clicking sound.

14.Connect the negative battery terminal to body ground, and connect the positive battery terminal to each solenoid terminal individually.

  • If a clicking sound is heard, go to 15 and replace the solenoid harness.
  • If no clicking sound is heard, go to 16 and replace shift solenoid valve.

15.Remove the shift solenoid harness connector (A), and replace it. Install the new O-ring (B) on the shift solenoid harness connector, and install the connector in the transmission housing, then go to 21.

 

16.Remove the mounting bolts, then hold the solenoid valve body and remove the solenoid valves. Do not hold the connector to remove the solenoid valve.

 

17.Install new O-rings (two O-rings per solenoid valve) (E) on the reused solenoid valve.

NOTE: A new solenoid valve comes with new O-rings. If you install a new solenoid valve, use the O-rings provided on it.

18.Install shift solenoid valve D (black connector) and shift solenoid valve C (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the servo body.

NOTE: Do not hold the solenoid valve connector to install the solenoid valve. Be sure to hold the solenoid valve body.

19.Install shift solenoid valve B (black connector) by holding the solenoid valve body; make sure the mounting bracket contacts the servo body.

20.Install shift solenoid valve A (brown connector) by holding the shift solenoid valve body; make sure the mounting bracket contacts the bracket of shift solenoid valve B.

NOTE: Do not install shift solenoid valve A before installing shift solenoid valve B. If shift solenoid valve A is installed before installing shift solenoid valve B, it may damage to hydraulic control system.

21.Connect BLU harness terminal to shift solenoid valve A, ORN harness terminal to shift solenoid valve B, GRN harness terminal to shift solenoid valve C, and YEL harness terminal to shift solenoid valve D.

22.Install the shift solenoid valve cover, dowel pins, a new gasket, and harness clamp bracket.

23.Check the connector for rust, dirt, or oil, then connect the connector securely.

24.Refill the transmission with ATF.

25.Install the splash shield.
