Pressure Testing
TESTINGWARNING:
- 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 to normal operating temperature before testing.
- While testing, be sure not to allow dust and other foreign particles to enter into the transmission.
1. Raise the front of the vehicle, and support it with safety stands.
2. Set the parking brake, and block both 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 each inspection hole.
TORQUE: 18 Nm (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.
- When troubleshooting by the [D] indicator light indicates a problem, you must use an oil pressure gauge that measures 4,900 kPa (711 psi) or more when measuring drive pulley pressure and driven pulley pressure.
NOTE:
- Drive pulley pressure may be above 3,430 kPa (498 psi) when there is a transmission problem that causes the Transmission Control Module (TCM) or Powertrain Control Module (PCM) to go into the fail-safe mode.
- Use a commercially available oil pressure gauge that measures 4,900 kPa (711 psi) or more, and the A/T Oil Pressure Hose, 2210 mm (07MAJ - PY4011A).
6. Start the engine.
7. Shift to the respective shift lever positions in the table, and measure the following pressures at 1,500 rpm.
- Forward Clutch Pressure
- Reverse Brake Pressure
- Drive Pulley Pressure
- Driven Pulley Pressure
8. Shift to [N] position, and measure the lubrication pressure at 3,000 rpm.
9. Disconnect the special tool after pressure testing.
10. Install the sealing bolts in the inspection holes with new sealing washers, and tighten the bolts to the specified torque.
TORQUE: 18 Nm (13 ft. lbs.)
CAUTION: Keep all foreign particles out of the transmission.
