Pressure Test
Pressure TestSpecial Tools Required
^ A/T oil pressure gauge set w/panel 07406-0020400 or 07406-0020401
^ A/T pressure hose, 2,210 mm 07MAJ-PY4011A
^ A/T pressure hose adapter 07MAJ-PY40120
1. Make 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. Or raise the vehicle.
3. Connect the oil pressure gauge to the line pressure inspection port (A) and 4th clutch pressure inspection port (B). Do not allow dust or other foreign particles to enter the holes while connecting the gauges.
4. Remove the air cleaner housing, and connect the oil pressure gauge to the 2nd clutch pressure inspection port (C). Then temporarily reinstall the air cleaner housing.
5. Connect the oil pressure gauges to the 1st clutch pressure inspection port (D) and 3rd clutch pressure inspection port (E).
6. Warm up the engine (the radiator fan comes on), then stop it and connect the HDS to the DLC.
7. Start the engine, and run it at 2,000 rpm.
8. Shift to the N or P position, and measure the line pressure the at the line pressure inspection port (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 the 1st clutch pressure at the 1st clutch pressure inspection port (D) while holding engine speed at 2,000 rpm.
10. Shift to the 2 position, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (C) while holding engine speed at 2,000 rpm.
11. Shift to the P position, then press the brake pedal and hold it.
12. Shift to the D position, and turn the over drive off mode by pressing the O/D switch. Release the brake pedal; the transmission is in 1st gear.
13. Press the accelerator pedal to increase engine speed to 2,500 rpm; the transmission shifts to 2nd gear.
14. Release the accelerator pedal to close fully the throttle over 5 seconds; the engine speed decrease to 1,000 rpm with the transmission in 2nd gear.
15. Press the accelerator pedal very slowly to increase the engine speed to 2,000 rpm over 5 seconds, and hold the accelerator; the transmission shifts to 3rd gear. Measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (D) while holding engine speed at 2,000 rpm.
16. Release the over drive mode by pressing the O/D switch; the transmission shifts to 4th gear. Measure the 4th clutch pressure at the 4th clutch pressure inspection port (B) while holding engine speed at 2,000 rpm.
17. Shift to the R position, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (B) while holding engine speed at 2,000 rpm.
18. If the measurements are out of service limit, problems and probable causes are listed in the table:
19. Install the sealing bolts with new sealing washers, and tighten the bolts to the specified torque.
Torque: 18 Nm (1.8 kgf-m, 13 ft. lbs.)
NOTE: Do not reuse old sealing washers.
20. Install the air cleaner housing.
