8. Measure the A/T clutch pressure control solenoid valve B resistance at the

connector terminals.

2006-08 TRANSMISSION Automatic Transmission - Civic (Except Hybrid)

Standard: 3-10 ohms

If the resistance is out of standard, replace A/T clutch pressure control
solenoid valve B (see A/T CLUTCH PRESSURE CONTROL
SOLENOID VALVE B AND C REPLACEMENT ).

If the resistance is within the standard, go to step 9.

9. Connect a jumper wire from the negative battery terminal to A/T clutch

pressure control 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. Reconnect the connector, and
install all removed parts.

If no clicking sound is heard, go to step 10.

10. Remove A/T clutch pressure control solenoid valve B and C.

11. Remove the ATF pipe (A), the ATF joint pipes (D), the O-rings (E), and the

gasket (F).

12. Check the fluid passage of the solenoid valve for contamination.
13. Connect a jumper wire from the negative battery terminal to A/T clutch

pressure control solenoid valve B 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 B moves.

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
pressure control solenoid valves B and C.

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.

17. Install the ATF pipe and the ATF joint pipes, and install new O-rings over the

ATF joint pipes.

18. Install A/T clutch pressure control solenoid valves B and C.
19. Check the A/T clutch pressure control solenoid valve B and C connectors for

rust, dirt, or oil, 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

ELEMENT INSPECTION/REPLACEMENT ).

A/T CLUTCH PRESSURE CONTROL SOLENOID VALVE C TEST

1. Connect the HDS to the DLC (A) located behind the driver's dashboard lower

cover.

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 C in the Miscellaneous

Test Menu on the HDS.

4. Test A/T clutch pressure control solenoid valve C 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).
