14. Disconnect one of the jumper wires and check the 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

15. Clean the mounting surfaces and fluid passages of the solenoid valve body and

the transmission housing.

16. Install a new gasket with the blue side down and the white side up on the

transmission housing, and install the ATF pipe and the ATF joint pipes.

17. Install new O-rings over the ATF joint pipes.
18. Install A/T clutch pressure control solenoid valve A.
19. Check the connectors for rust, dirt, or oil, clean or repair if necessary, then

connect the connectors securely.

20. Secure the harness cover with the mounting bolts, and install the harness

clamp.

21. Install the intake air duct and the air cleaner assembly (see AIR CLEANER

REMOVAL/INSTALLATION )

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 Clutch Pressure Control (Linear) Solenoid Valve B in the Miscellaneous

Test Menu with the HDS.

4. Test A/T clutch pressure control solenoid valve B 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. Remove the air cleaner assembly (see AIR CLEANER ELEMENT

INSPECTION/REPLACEMENT ) and the intake air duct.

6. Remove the mounting bolts securing the harness cover (A), and remove the

harness clamp (B).
