9. Remove the mounting bolts and A/T clutch
pressure control solenoid valve A.
10. Remove the ATF pipe (B), the ATF joint pipes (C), the O-rings (D), and the gasket (E).
11. Check the fluid passage of the solenoid valve for contamination. 12. Connect a jumper wire from the negative battery
terminal to A/T clutch pressure control solenoid
valve A connector terminal No. 2, and connect
another jumper wire from the positive battery
terminal to connector terminal No. 1. Make sure
A/T clutch pressure control solenoid valve A moves.
13. Disconnect one of the jumper wires, and check 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 pressure control solenoid
valve A.
14. Clean the mounting surfaces and the fluid passages of the A/T clutch pressure control solenoid valve
body and the transmission housing.
15. Install a new gasket on the transmission housing, and install the ATF pipe and the ATF joint pipes.
NOTE: Be sure to install a new gasket with the blue
side toward the transmission housing.
16. Install new O-rings over the ATF joint pipes.
17. Install A/T clutch pressure control solenoid valve A.
18. Check the connectors for rust, dirt, or oil, clean or repair if necessary, then connect the connectors
securely.
19. Install the air cleaner assembly (see page 11-345) and the intake air duct (see page 11-348).

A/T Clutch Pressure Control Solenoid Valve B Test

1. Connect the HDS to the DLC (A) located under thedriver’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 page
11-204).
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 intake air duct (see page 11-348) and the air cleaner assembly (see page 11-345). 6. Disconnect the A/T clutch pressure control solenoid
valve B connector (A).
7. Measure the resistance between A/T clutch pressure control solenoid valve B connector
terminals No. 1 and No. 2.
 If the resistance is within the standard, go to step 8.
 If the resistance is out of standard, replace A/T clutch pressure control solenoid valve B
(see page 14-226).
8. Connect a jumper wire from the negative battery terminal to solenoid valve B connector terminal
No. 2, and connect another jumper wire from the
positive battery terminal to connector terminal
No. 1.
 If a clicking sound is heard, the valve is OK, and the test is complete, go to step 18.
 If no clicking sound is heard, go to step 9.
