Pressure Tests

Tests

Special Tools Required
^ A/T oil pressure gauge set 07406-0020400 or 07406-0020401
^ A/T pressure hose, 2210 mm 07MAJ-PY4011A
^ A/T pressure hose adapter 07MAJ-PY40120

1. Before testing, be sure the transmission is filled to the proper level.
2. 4WD model: Raise the vehicle, make sure it is securely supported, and allow all four wheels to rotate freely. 2WD model: Raise the front of the vehicle, and make sure it is securely supported. Set the parking brake, block rear wheels securely, and allow the front wheels to rotate freely.
3. Warm up the engine (the radiator fan comes on), then turn the engine off, and connect the tachometer.





4. Connect the oil pressure gauge to the line pressure inspection hole (A) and 4th clutch pressure inspection hole (B). Do not allow dust or other foreign particles to enter the holes while connecting the gages.





5. Remove the air cleaner housing, and connect the oil pressure gauge to the 2nd clutch pressure inspection hole (C). Then temporarily reinstall the air cleaner housing.





6. Connect the oil pressure gauges to the 1st clutch pressure inspection hole (D) and 3rd clutch pressure inspection hole (E).
7. Start the engine, and run it at 2,000 rpm.





8. Shift to the N or P position, and measure line pressure at the line pressure inspection hole (A).

NOTE: Higher pressure may be indicated if measurements are made in shift lever position other than N or P.

9. Shift to the 1 position, and measure 1st clutch pressure at the 1st clutch pressure inspection hole (D) while holding engine speed at 2,000 rpm.
10. Shift to the [2] position, and measure 2nd clutch pressure at the 2nd clutch pressure inspection hole (C) while holding engine speed at 2,000 rpm.
11. Shift to the [D] position, and turn the over drive off by pushing the O/D switch. Measure 3rd clutch pressure at the 3rd clutch pressure inspection hole (E) while holding engine speed at 2,000 rpm.
12. Measure 4th clutch pressure at the 4th clutch pressure inspection hole (B) while holding engine speed at 2,000 rpm.





13. Shift to the R position, and measure 4th clutch pressure at the 4th clutch pressure inspection hole (B) while holding engine speed at 2,000 rpm.





14. If the measurements are out of service limit, problems and probable causes are listed in the table.
15. Install the sealing bolts with new sealing washers, and tighten the bolts to the specified torque.
TORQUE: 18 Nm (1.8 kgf-cm, 13 ft. lbs.)

NOTE: Do not reuse old sealing washers.

16. Install the air cleaner housing.
