Pressure Test
Pressure TestSpecial Tools Required
^ A/T oil 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. Raise the vehicle on a lift, or apply the parking brake, block the 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. Connect the HDS to the DLC (A), and go to the A/T DATA LIST.
6. Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting.
7. Connect the A/T oil pressure gauge to the line pressure inspection port (A). Do not allow dust or other foreign particles to enter the hole while connecting the gauge.
8. Start the engine in P, and warm it up to normal operating temperature (the radiator fan comes on).
9. Measure the line pressure at the line pressure inspection port (A) in P or N while holding the engine speed at 2,000 rpm.
NOTE: Higher pressure may be indicated if measurements are made in the shift lever position other than P or N.
10. Turn the engine off, then disconnect the A/T oil pressure gauge from the line pressure inspection port.
11. Install the sealing bolt to the line pressure inspection port with a new sealing washer, and tighten the bolts to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washer.
12. Connect the A/T oil pressure gauge to the 1st clutch pressure inspection port (B) and the 1st-hold clutch pressure inspection port (C).
13. Remove the intake air duct and the air cleaner assembly, and connect the A/T oil pressure gauge to the 2nd clutch pressure inspection port (D). Then temporarily install the air cleaner assembly and the intake air duct.
14. Start the engine in P, and shift into M.
15. Shift to 1st gear, and measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) and the 1st-hold clutch pressure at the 1st-hold clutch pressure inspection port (C) while holding the engine speed at 2,000 rpm.
16. Shift up to 2nd gear, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm.
17. Turn the engine off, then disconnect the A/T oil pressure gauges from the 1st clutch pressure, the 1st-hold clutch pressure, and the 2nd clutch pressure inspection ports.
18. Install the sealing bolts to the 1st clutch pressure, the 1stclutch hold clutch pressure, and the 2nd clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washers.
19. Connect the A/T oil pressure gauge to the 3rd clutch pressure inspection port (E) and the 5th clutch pressure inspection port (G).
20. Remove the intake air duct and the air cleaner assembly, and connect the A/T oil pressure gauge to the 4th clutch pressure inspection port (F). Then temporarily install the air cleaner assembly and the intake air duct.
21. Start the engine with the transmission in P while pressing the brake pedal.
22. Shift to M, and release the brake pedal; the transmission is in 1st gear.
23. Press the accelerator pedal to increase the engine speed to 2,500 rpm, then shift to 2nd gear.
24. Release the accelerator pedal; the engine speed decreases to 1,000 rpm with the transmission in 2nd gear.
25. Press the accelerator pedal very slowly so that the engine speed increases to 2,000 rpm in 5 seconds, then hold the accelerator. Shift to 3rd gear, and measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (E) while holding the engine speed at 2,000 rpm.
26. Shift to 4th gear, and measure the 4th clutch pressure at the 4th clutch pressure inspection port (F) while holding the engine speed at 2,000 rpm.
27. Measure the 5th clutch pressure at the 5th clutch pressure inspection port (G) while holding the engine speed at 2,000 rpm.
28. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating.
29. Shift to R, 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 port (G).
30. Turn the engine off, then disconnect the A/T oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports.
31. Install the sealing bolts to the 3rd, 4th, and 5th clutch pressure inspection ports with new sealing washers, and tighten the bolts to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washers.
32. If any of the pressures are out of the service limit, the problems and probable causes are listed in the table.
33. Install the intake air duct and the air cleaner assembly.
34. Install the splash shield.
