14-208Automatic Transmission
Road Test
A
1. Apply the parking brake, and block both rear
wheels.
2. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
3. Shift to D while pressing the brake pedal. Press the accelerator pedal, and release it suddenly. The
engine should not stall.
4. Repeat step 3 in all shift lever positions.
5. Connect the HDS to the DLC (A) located under the driver’s side of the dashboard.
6. Turn the ignition switch to ON (II), and go to the A/T Data List. Make sure the HDS communicates with
the PCM. If it does not, go to the DLC circuit
troubleshooting (see page 11- 204).7. Prepare the HDS to take a HIGH SPEED SNAPSHOT
(refer to the HDS user guide for more details if
needed):
 Select High Speed icon.
 Select these parameters: – Vehicle Speed
– Output Shaft (Countershaft) Speed (rpm)
– Input Shaft (Mainshaft) Speed (rpm)
– Engine Speed
– APP Sensor A (V)
– ATF Temp Sensor (V)
– Battery Voltage
– Shift Control
– Brake Switch
 Set the Trigger Type to Parameter.
 Adjust the Parameter setting to APP Sensor A above 1.2 V.
 Set the recording time to 60 seconds.
 Set the Trigger point to 30 seconds.
8. Find a suitable level road. When you are ready to do the test, press OK on the HDS.
9. Monitor the HDS and accelerate quickly until the APP Sensor A reads 1.3 V. Maintain a steady
throttle until the transmission shifts to 5th gear,
then slow the vehicle and come to a stop.
10. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 9.
11. Adjust the Parameter setting to 2.4 V. Retest-drive the vehicle. While monitoring the HDS, accelerate
quickly until the APP Sensor A reads 2.5 V.
Maintain a steady throttle until the transmission
shifts to 5th gear (or reasonable speed), then slow
the vehicle and come to a stop.
12. Save the snapshot if the entire event was recorded or increase the recording time setting as necessary
and repeat step 11.
13. Accelerate quickly until the accelerator pedal is to the floor. Maintain a steady pedal until the
transmission shifts to 3rd gear, then slow to a stop,
and save the snapshot.

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).

12 N·m (1.2 kgf·m, 8.7 lbf·ft)
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.
