Pressure Tests

PRESSURE TESTING

WARNING: While testing, be careful of the rotating rear wheels. Make sure lifts 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 vehicle.
2. Warm up the engine, then stop the engine and connect a tachometer.





3. Connect a pressure gauge to each inspection hole. 18 Nm (1.8 kg/m; 13 ft. lbs.)

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

4. Start the engine, and measure the respective pressure as follows.
- Line Pressure/Clutch Pressure
- Clutch Low/High Pressure
- Throttle B Pressure
5. Install a new washer and the sealing bolt in the inspection hole, and tighten to the specified torque.

Torque: 18 Nm (1.8 kgf-m, 13 ft. lbs.)

NOTE: Do not reuse old aluminum washers.





- Line Pressure/Clutch Pressure Measurement
1. Allow the rear wheels to rotate freely.
2. Run the engine at 2,000 rpm.
3. Shift the shift lever as shown on the chart.
4. Measure each clutch pressure.

WARNING: While testing, be careful of the rotating rear wheels.

- Clutch Low/High Pressure Measurement

WARNING: While testing, be careful of the rotating rear wheels.





1. Allow the rear wheels to rotate freely.
2. Start the engine and let it idle.
3. Shift to [D] position.
4. Slowly press down the accelerator pedal to increase engine rpm until pressure is indicated on the oil pressure gauge. Then release the accelerator pedal, allowing the engine return to an idle, and measure the pressure reading.
5. With the engine idling, press down the accelerator pedal approximately 1/2 of its possible travel and increase the engine rpm until pressure is indicated on the gauge. Note the highest pressure reading obtained.
6. Repeat steps 4 and 5 for each clutch pressure being inspected.

- Throttle B Pressure Measurement

WARNING: While testing, be careful of the rotating rear wheels.





1. Allow the rear wheels to rotate freely.
2. Disconnect the linear solenoid connector.
3. Shift to [D] position.
4. Run the engine at 2,000 rpm.
5. Measure fully opened throttle B pressure.
6. Connect battery voltage to the linear solenoid terminal of the connector.
7. Measure fully closed throttle B pressure.
