Pressure Test
Pressure TestSpecial 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. 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. Remove the splash shield.
5. Warm up the engine (the radiator fan comes on). Turn off the engine, and connect the HDS to the DLC (A).
6. 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.
7. Start the engine, and run it at 2,000 rpm in the P or N position.
8. Measure the line pressure at the line pressure inspection hole (A).
NOTE: Higher pressure may be indicated if measurements are made in any shift lever position other than P or N.
9. Turn the engine off, then disconnect the oil pressure gauge from the line pressure inspection hole.
10. Install the sealing bolt to the line pressure inspection hole with the new sealing washer, and tighten the bolt to 18 Nm (1.8 kgf-m, 13 ft. lbs.). Do not reuse the old sealing washer.
11. Connect the oil pressure gauge to the 1st clutch pressure inspection hole (B).
12. Remove the intake air duct and air cleaner housing, and connect the oil pressure gauge to the 1st-hold clutch pressure inspection hole.
13. Connect the oil pressure gauge to the 2nd clutch pressure inspection hole (D). Then temporarily install the air cleaner housing and intake air duct.
14. Start the engine, and shift to the 1 position. Measure the 1st clutch pressure at the 1st clutch pressure inspection hole (B) and the 1st-hold clutch pressure at the 1st-hold clutch pressure inspection hole (C) while holding the engine speed at 2,000 rpm.
15. Shift to the 2 position, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection hole (D) while holding the engine speed at 2,000 rpm.
16. Turn the engine off, then disconnect the oil pressure gauges from the 1st clutch pressure, 1st hold clutch pressure, and 2nd clutch pressure inspection holes.
17. Install the sealing bolts in the 1st clutch pressure, 1st-hold 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.
18. Connect the oil pressure gauge to the 3rd clutch pressure inspection hole (E).
19. Connect the oil pressure gauge to the 4th clutch pressure inspection hole (F).
20. Connect the oil pressure gauge to the 5th clutch pressure inspection hole (G).
21. Start the engine with the transmission in the P position while pressing the brake pedal.
22. Shift to the 2 position, and release the brake pedal; the transmission is; in 2nd gear.
23. Press the accelerator pedal very slowly so that the engine speed increases to 2,000 rpm in 10 seconds, then hold the accelerator.
24. Hold in the 2 position at 2,000 rpm, shift into N for 1 second, then to the D3 position; the transmission will shift to 3rd gear, and measure the 3rd clutch pressure at the 3rd clutch pressure inspection hole (E) while holding the engine speed at 2,000 rpm.
25. Shift to the D position, and measure the 4th clutch pressure at the 4th clutch pressure inspection hole (F) while holding the engine speed at 2,000 rpm, then in about 15 seconds, the transmission will shift to the 5th gear.
26. Measure the 5th clutch pressure at the 5th clutch pressure inspection hole (G) while holding the engine speed at 2,000 rpm.
27. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating.
28. Shift to the R position, then release the brake pedal. Raise the engine speed to 2,000 rpm, and measure the 5th clutch pressure at the 5th clutch pressure inspection hole (G).
29. Turn the engine off, then disconnect the oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection holes.
30. 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.
31. If the measurements are out of the service limit, problems and probable causes are listed in the table.
32. Install the air cleaner housing and intake air duct.
33. Install the splash shield.
