Pressure Tests

PRESSURE TESTING

WARNING:
- While testing, be careful of the rotating front wheels.
- Make sure lifts, jacks and safety stands are placed properly.

CAUTION:
- Before testing, be sure the transmission fluid is filled to the proper level.
- Warm up the engine before testing.

1. Raise the front of the vehicle, and support it with safety stands.
2. Set the parking brake, and block rear wheels securely.
3. Allow the front wheels to rotate freely.
4. Warm up the engine (the radiator fan comes on), then stop and connect a tachometer.
5. Connect the special tool to line pressure inspection hole.

TORQUE: 18 Nm (1.8 kgfm, 13 ft. lbs.)

CAUTION: Connect the oil pressure gauge securely, be sure not to allow dust and other foreign particles to enter the inspection hole.

NOTE: The A/T Oil Pressure Gauge Set (07406 - 0020003) or A/T Low Pressure Gauge (07406 - 0070000) may also be used.

6. Disconnect the transmission sub-harness connector (114P).





7. Start the engine, and run it at 2,000 rpm.
8. Shift to the R or k position, and measure line pressure at fully-opened throttle.
9. Connect battery voltage to the linear solenoid terminals of the transmission sub-harness connector as shown.
10. Measure line pressure at fully-closed throttle.
If line pressure is out of specification, check and repair the probable cause in the table below.





11. Stop the engine, and connect the transmission sub-harness connector (14P).
12. Disconnect the special tool from line pressure inspection hole, and connect the special tool to each inspection hole.
13. Start the engine, and run it at 2,000 rpm.





14. Shift to the respective shift lever position, and measure each clutch pressure.
15. Disconnect the transmission sub-harness connector (14P), then measure throttle B pressure with the throttle fully opened.
16. Connect battery voltage to the linear solenoid terminals of the transmission sub-harness connector as shown.
17. Measure throttle B pressure at fully-closed throttle.





18. Install the sealing bolt with anew sealing washer in the inspection hole, and tighten the bolt to the specified torque.

TORQUE: 18 Nm (1.8 kgfm, 13 ft. lbs.)

NOTE: Do not reuse old sealing washer.
