Pressure Test
Pressure TestSpecial 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. 4WD model: Raise the vehicle on a lift, make sure it is securely supported, and allow all four wheels to rotate freely.
2WD model: Raise the front of the vehicle, 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 on a lift.
3. Remove the splash shield.
4. Connect the oil pressure gauge to the line pressure inspection port (A). Do not allow dust or other foreign particles to enter the port while connecting the gauge.
5. Warm up the engine (the radiator fan comes on), then stop it and connect the HDS to the DLC (A).
NOTE: If the HDS does not communicate with the PCM, troubleshoot the DLC circuit.
6. Start the engine, and run it at 2,000 rpm in the P or N position.
7. Measure the line pressure.
NOTE: Higher pressure may be indicated if measurements are made with shift lever in a position other than P or N.
8. Turn the engine off, then disconnect the oil pressure gauge from the line pressure inspection port.
9. Install the sealing bolt to the line pressure inspection port with the new sealing washer, and tighten the bolts to 18 Nm (1.8 kgf-m, 13 lbf-ft). Do not reuse old sealing washer.
10. Connect the oil pressure gauge to the 1st clutch pressure inspection port.
11. Remove the intake air duct and air cleaner assembly, and connect the oil pressure gauge to the 2nd clutch pressure inspection port (C). Then temporarily install the air cleaner assembly and intake air duct.
12. Start the engine, shift to the 1 position, and measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) while holding engine speed at 2,000 rpm.
13. 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.
14. Turn the engine off, then disconnect the oil pressure gauges from the 1st clutch pressure and 2nd clutch pressure inspection ports.
15. Install the sealing bolts to the 1st clutch pressure and 2nd clutch pressure inspection ports with the new sealing washers, and tighten the bolts to 18 Nm (1.8 kgf-m, 13 lbf-ft). Do not reuse old sealing washers.
16. Connect the oil pressure gauge to the 3rd clutch pressure inspection port (D) and 5th clutch pressure inspection port (F).
17. Connect the oil pressure gauge to the 4th clutch pressure inspection port (E).
18. Choose Pressure Test Assistance Mode in the Miscellaneous Test Menu of the A/T Mode Menu.
19. Start the engine, then shift to the D position and select D3 driving mode by pressing the D3 switch.
20. Measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm.
21. Press the D3 switch one more, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E) and the 5th clutch pressure at the 5th clutch pressure inspection port (F) while holding the engine speed at 2,000 rpm.
22. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating.
23. Shift to the R position, then release the brake pedal. Raise the engine speed to 2,000 rpm, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (E).
24. Turn the engine off, then disconnect the oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports.
25. Install the sealing bolts to the 3rd, 4th, and 5th clutch pressure inspection ports with the new sealing washers, and tighten the bolts to 18 Nm (1.8 kgf-m, 13 lbf-ft). Do not reuse old sealing washers.
26. If the measurements are out of the service limit, problems and probable causes are listed in the table.
27. Install the air cleaner assembly and intake air duct.
28. Install the splash shield.
