23. Start the engine, and shift to S.
24. Upshift to 3rd gear by pressing the paddle shifter
(upshift switch), and measure the 3rd clutch
pressure at the 3rd clutch pressure inspection port
(D) while holding the engine speed at 2,000 rpm.
25. Upshift to 4th gear, and measure the 4th clutch

(F) while holding the engine speed at 2,000 rpm.
26. Upshift to 5th gear, and measure the 5th clutch
pressure at the 5th clutch pressure inspection port
(E) while holding the engine speed at 2,000 rpm.

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.

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
problems and probable causes are listed in 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).
Replace.

13. Disconnect the shift solenoid wire harness
connector, and remove it from the transmission
housing.
14. Measure the shift solenoid valve resistance
between the following shift solenoid wire harness
connector terminals and body ground:
• No. 1 (GRN): Shift solenoid valve C
• No. 2 (ORN): Shift solenoid valve B
• No. 3 (RED): Shift solenoid valve E
• No. 5 (BLU): Shift solenoid valve A
• No. 8 (YEL): Shift solenoid valve D
15. If the resistance is within the standard, go to step
17 and check the solenoid valve for a clicking
sound. If the resistance is out of standard, go to
step 16.
16. Disconnect the shift solenoid valve connector, and
measure the resistance at the solenoid valve
connector. Replace the shift solenoid valve if the
resistance is out of standard, then go to step 20.
17. Connect a jumper wire from the battery positive
terminal to the shift solenoid wire harness
connector terminals, and connect another jumper
wire from the battery negative terminal to body
ground individually. A clicking sound should be
heard.
• If a clicking sound is heard, the valves are OK,
and the test is complete, connect the connector.
• If no clicking sound is heard, replace the shift
solenoid valve (see page 14-217).
18. Replace the shift solenoid harness if the test results
are OK.
19. Install a new O-ring on the shift solenoid wire
harness connector, and install the connector in the
transmission housing.
20. Install a new gasket, the dowel pins, and the shift
solenoid valve cover.
21. Check the shift solenoid wire harness connector for
rust, dirt, or oil, then connect the connector
securely.
22. Refill the transmission with ATF (see step 5 on page
14-232).
23. Install the battery tray, the battery base, and the
resonator.
24. Install the air cleaner assembly (see page 11-345)
and the intake air duct (see page 11-348).
25. Do the battery installation procedure (see page
22-69).
26. Install the splash shield.
