Pressure Test

Pressure Test
Special Tools Required
- A/T clutch pressure gauge set 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. Raise the vehicle, and make sure it is securely supported.
3. Allow all four wheels to rotate freely.





4. Connect the HDS to the DLC (A).
5. Remove the splash shield.





6. Connect the oil pressure gauges to the line pressure inspection port (A), 5th clutch pressure inspection port (B), and 3rd clutch pressure inspection port (C) at the front lower of the transmission. Do not allow dust or other foreign particles to enter the ports while connecting the gauges.
7. Warm up the engine (the radiator fan comes on), then stop it.





8. Remove the intake air duct, and connect the oil pressure gauges to the 2nd clutch pressure inspection port (D) and 4th clutch pressure inspection port (E). Then temporarily install the air cleaner housing and intake air duct.





9. Connect the oil pressure gauge to the 1st clutch pressure inspection port (F), and 1st-port clutch pressure inspection port (G) at the transmission end cover.
10. Start the engine, and run it at 2,000 rpm in the P or N position.
11. Measure the line pressure 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.





12. Shift to the 1 position, and measure the 1st clutch pressure at the 1st clutch pressure inspection port (F) and 1st-hold, clutch pressure at the 1st-hold, clutch pressure inspection port (G).
13. Shift to the 2 position, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (D).
14. Shift to the P position, then press the brake pedal and hold it.
15. Shift to the D3 position, and release the brake pedal; the transmission is in 1st gear.
16. Press the accelerator pedal to increase the engine speed to 2,500 rpm; the transmission shifts to 2nd gear.
17. 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.
18. Press the accelerator pedal very slowly to increase the engine speed 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 (C) while holding engine speed at 2,000 rpm.
19. Shift to the D4 position (the transmission will shift to 4th gear at about 2,500 rpm), reduce the engine speed to 2,000 rpm, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E).
20. Shift to the D5 position (the transmission will shift to 5th gear at about 2,500 rpm), reduce the engine speed to 2,000 rpm, and measure the 5th clutch pressure at the 5th clutch pressure inspection port (B).
21. Bring the engine back to an idle, then apply the brake to stop the wheels from rotating.
22. Shift to the R position. Raise the engine rpm to 2,000 rpm, and measure the 5th clutch pressure at the 5th clutch pressure inspection port (B).





23. If the measurements are out of the service limit, problems and probable causes are listed in the table.





24. Install the sealing bolts with the new sealing washers, and tighten the bolts to 18 Nm (1.8 kgf-m, 13 ft. lbs.). Do not reuse old sealing washers.
Torque: 18 Nm (1.8 kgf-m, 13 ft. lbs.).

25. Install the air cleaner housing and intake air duct.
26. Install the splash shield.
