27. Bring the engine back to an idle, then apply the
brake pedal to stop the wheels from rotating.
28. Shift to R, then release the brake pedal. Measure the 4th clutch pressure at the 4th clutch pressure
inspection port (F) while holding the engine speed
at 2,000 rpm.
4th clutch

29. Turn the engine off, then disconnect the A/T oil pressure gauge from the 3rd, 4th, and 5th clutch
pressure inspection ports.
30. Install the sealing bolts in the 3rd, 4th, and 5th clutch pressure inspection ports with new sealing
washers, and tighten the bolts to 18 N·m (1.8 kgf·m,
13 lbf·ft). Do not reuse the old sealing washers. 31. If the pressures are out of the service limit, the

1. Connect the HDS to the DLC (A) located under the driver’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 Shift Solenoid Valves A, B, C, D, and E Test in the Miscellaneous Test Menu with the HDS.
4. Check that shift solenoid valves A, B, C, D, and E 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 step 5, and test the solenoid valve.
5. Do the battery removal procedure (see page 22-69).
6. Remove the intake air duct (see page 11-348) and the air cleaner assembly (see page 11-345).
7. Remove the battery tray, the battery base, and the resonator.
8. Raise the vehicle on a lift, or apply the parking brake, block the rear wheels, and raise the front of
the vehicle. Make sure it is securely supported.
9. Remove the splash shield. 10. Remove the drain plug (A), and drain the automatic
transmission fluid (ATF).
11. Reinstall the drain plug with a new sealing washer (B).
12. Remove the shift solenoid valve cover (A), the dowel pins (B), and the gasket (C).

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).
