Pressure Tests

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. Before testing, be 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. Warm up the engine (the radiator fan comes on), then stop it and connect the HDS to the DLC (A).
5. Remove the splash shield.








6. Connect the oil pressure gauges to the line pressure inspection hole (A), 5th clutch pressure inspection hole (B), and 3rd clutch pressure inspection hole (C) at the front lower of the transmission. Do not allow dust or other foreign particles to enter the holes while connecting the gauges.





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





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

11. Shift to the 1 position, and measure 1stclutch pressure at the 1st clutch pressure inspection hole (F) and 1st-hold clutch pressure at the 1st-hold clutch pressure inspection hole (G).
12. Shift to the 2 position, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection hole (D).
13. Shift to the P position, then press the brake pedal and hold it.
14. Shift to the 2 position, and release the brake pedal (the transmission should be in 2nd gear).
15. Press the accelerator very slowly to increase engine speed to 2,000 rpm gradually over 10 seconds, then hold it at 2,000 rpm.
16. Hold in the 2 position at 2,000 rpm, shift into the N position for 1 second, then shift to the D3 position (the transmission will shift to 3rd gear), and measure 3rd clutch pressure at the 3rd clutch pressure inspection hole (C).
17. 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 4th clutch pressure at the 4th clutch pressure inspection hole (E).
18. 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 5th clutch pressure at the 5th clutch pressure inspection hole (B).
19. Bring the engine back to an idle, then apply the brake to stop the wheels from rotating.





20. Shift to the R position. Raise the engine rpm to 2,000 rpm, and measure 5th clutch pressure at the 5th clutch pressure inspection hole (B).





21. If the measurements are out of the service limit, problems and probable causes are listed in the table.
22. Install the sealing bolts with the new sealing washers, and tighten the bolts to 18 Nm (1.8 kgf-cm, 13 ft. lbs.). Do not reuse old sealing washers.
Torque: 18 Nm (1.8 kgf-cm, 13 ft. lbs.)
23. Install the air cleaner housing and intake air duct.
24. Install the splash shield.
