Pressure Test

Pressure Test

Special Tools Required
- A/T clutch 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 fluid is filled to the proper level.
2. Lift the vehicle up on a lift or apply the parking brake, block rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Allow the front wheels to rotate freely.
4. Connect the oil pressure gauge to the line pressure inspection hole (A). Do not allow dust or other foreign particles to enter the hole while connecting the gauge.





5. Warm up the engine (the radiator fan comes on). Turn off the engine, and connect the HDS to the DLC (A).





6. Start the engine, and run it at 2,000 rpm in the P or N position.
7. 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 the P or N position.





8. Turn the engine off, then disconnect the oil pressure gauge from the line pressure inspection hole.
9. Install the sealing bolt in the line pressure inspection hole with a new sealing washer, and tighten the bolt to 18 Nm (1.8 kgf-m, 13 ft. lbs.). Do not reuse old sealing washer.
10. Connect the oil pressure gauge to the 1st clutch pressure inspection hole (B).





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





12. Start the engine, and shift into the M position.
13. Shift to 1st gear, and measure 1st clutch pressure at the 1st clutch pressure inspection hole (B) while holding engine speed at 2,000 rpm.
14. Shift up to 2nd gear, and measure 2nd clutch pressure at the 2nd clutch pressure inspection hole (C) while holding engine speed at 2,000 rpm.





15. Turn the engine off, then disconnect the oil pressure gauges from the 1st clutch pressure and 2nd clutch pressure inspection holes.
16. Install the sealing bolts in the 1st clutch pressure and 2nd clutch pressure inspection holes with new sealing washers, and tighten the bolts to 18 Nm (1.8 kgf-m, 13 ft. lbs.). Do not reuse old sealing washers.
17. Connect the oil pressure gauge to the 3rd clutch pressure inspection hole (D) and 5th clutch pressure inspection hole (F).





18. Connect the oil pressure gauge to the 4th clutch pressure inspection hole (E).





19. Start the engine with the transmission in the P position while pressing the brake pedal.
20. Shift to the M position, and release the brake pedal; the transmission is in 1st gear.
21. Press the accelerator pedal to increase the engine speed to 2,500 rpm, then shift to 2nd gear.
22. 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.
23. Press the accelerator pedal very slowly to increase the engine speed to 2,000 rpm over 5 seconds, and hold the accelerator. Shift to 3rd gear, and measure 3rd clutch pressure at the 3rd clutch pressure inspection hole (D) while holding engine speed at 2,000 rpm.
24. Shift to 4th gear, and measure 4th clutch pressure at the 4th clutch pressure inspection hole (E) while holding engine speed at 2,000 rpm.
25. Shift to 5th gear, and measure 5th clutch pressure at the 5th clutch pressure inspection hole (F) while holding engine speed at 2,000 rpm.





26. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating.
27. Shift to the R position, then release the brake pedal. Raise the engine speed to 2,000 rpm, and measure 4th clutch pressure at the 4th clutch pressure inspection hole (E).





28. Turn the engine off, then disconnect the oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection holes.
29. Install the sealing bolts in the 3rd, 4th, and 5th clutch pressure inspection holes with new sealing washers, and tighten the bolts to 18 Nm. (1.8 kgf-m, 13 ft. lbs.). Do not reuse old sealing washers.
30. If the measurements are out of the service limit, problems and probable causes are listed in the table.





31. Install the air cleaner housing.
