A/T Pressure Test

A/T Pressure Test

Special Tools Required

- A/T oil 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. ATF Level Check

2. Raise the vehicle on a lift, and make sure it is securely supported.

3. Allow all four 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. If the HDS does not communicate with the PCM, troubleshoot the DLC circuit. Testing and Inspection






6. Connect the 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.

7. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).

8. 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 positions other than P or N.





9. Turn the engine off, then disconnect the oil pressure gauge from the line pressure inspection port.

10. Install the sealing bolt to the line pressure inspection port with a new sealing washer, and tighten the bolt to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washer.











11. Connect the oil pressure gauge to the 1st clutch pressure inspection port (B) and the 1st-hold clutch pressure inspection port (C).






12. Remove the air cleaner housing and the intake air duct, and connect the oil pressure gauge to the 2nd clutch pressure inspection port (D). Then temporarily install the air cleaner housing and the intake air duct.

13. Start the engine, disable the VSA by pressing the VSA OFF switch, then shift into S.

14. Shift into 1st gear by pulling the paddle shifter + (upshift switch), and measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) and 1st-hold clutch pressure at the 1st-hold clutch pressure inspection port (C) while holding the engine speed at 2,000 rpm.

15. Upshift to 2nd gear by pulling the paddle shifter + (upshift switch), and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm.





16. Turn the engine off, remove the air cleaner housing and intake air duct, then disconnect the oil pressure gauges from the 1st clutch pressure, 1st-hold clutch pressure, and 2nd clutch pressure inspection ports.

17. Install the sealing bolts in the 1st clutch pressure, 1st-clutch hold clutch pressure, and 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.

18. Install the air cleaner housing and the intake air duct.






19. Connect the oil pressure gauge to the 3rd clutch pressure inspection port (E) and the 5th clutch pressure inspection port (G).






20. Connect the oil pressure gauge to the 4th clutch pressure inspection port (F).

21. Start the engine, disable the VSA by pressing the VSA OFF switch, then shift to S.

22. Upshift to 3rd gear by pulling the paddle shifter + (upshift switch), and measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (D) while holding the engine speed at 2,000 rpm.

23. Upshift to 4th gear, and measure the 4th clutch pressure inspection port (E) while holding the engine speed at 2,000 rpm.

24. Upshift to 5th gear, and measure the 5th clutch pressure at the 5th clutch pressure inspection port (F) while holding the engine speed at 2,000 rpm.





25. Bring the engine back to an idle, then apply the brake pedal to stop the wheels from rotating.

26. Shift to R, then release the brake pedal. Raise the engine speed to 2,000 rpm, and measure 5th clutch pressure at the 5th clutch pressure inspection port (G).





27. Turn the engine off, then disconnect the oil pressure gauges from the 3rd, 4th, and 5th clutch pressure inspection ports.

28. Install the sealing bolts in the 3rd, 4th, and 5th clutch pressure inspection holes 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.

29. If any of the pressures are out of the service limit, refer to the possible problems and probable causes listed in the table.





30. Install the splash shield.

31. Retrieve any ABS DTCs with the HDS, and clear them.
