Honda Civic. Manual — part 240

19. 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.

20. Install shift solenoid valve B (black connector) by holding the shift solenoid

valve body; make sure the mounting bracket contacts the servo body.

21. 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.

22. Connect the shift solenoid harness connectors:

BLU wire to shift solenoid valve A.

ORN, WHT, and WHT wires to shift solenoid valve B.

GRN wire to shift solenoid valve C.

YEL wire to shift solenoid valve D.

23. Install the shift solenoid valve cover, the dowel pins, a new gasket, and the

harness clamp bracket.

24. Check the connector for rust, dirt, or oil, then connect the connector securely.
25. Refill the transmission with ATF (see step 5 ).
26. Install the splash shield.

NOTE:

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

NOTE:

Do not hold the solenoid valve by the connector when
installing the solenoid valve. Be sure to hold the
solenoid valve body.

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.

6. Disconnect the shift solenoid valve connectors.

If replacing shift solenoid valve(s), go to step 7.

If replacing the shift solenoid harness, remove the shift solenoid harness
connector (A), and replace it. Install a new O-ring (B) on the new shift
solenoid harness connector, and install it in the transmission housing, then
go to step 12.
