A/T Pressure Test

A/T Pressure Test

Special Tools Required

- A/T pressure gauge set 07406-0020400 or 07406-0020401
- A/T pressure hose, 2,210 mm 07MAJ-PY4011A
- A/T pressure hose adapter 07MAJ-PY40120
NOTE:

- Disable the VSA by pressing the VSA OFF switch.

- VSA DTC(s) may come on during the test-drive. If the VSA DTC(s) come on, clear the DTC(s) with the HDS.

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) located under the driver's side of the dashboard.

6. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM. If it does not, go to the DLC circuit troubleshooting. Testing and Inspection






7. 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.

8. Start the engine, 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 the P or N position 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 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 bolt to 18 N-m (1.8 kgf-m, 13 lbf-ft). Do not reuse the old sealing washer.











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






13. Remove the air cleaner, Service and Repair and connect the oil pressure gauge to the 2nd clutch pressure inspection port (D). Then temporarily install the air cleaner.

14. Start the engine, and shift into S.

15. Press the paddle shifter + (upshift switch), and make sure the transmission is in 1st gear. Measure the 1st clutch pressure at the 1st clutch pressure inspection port and 1st-hold clutch pressure at the 1st-hold clutch pressure inspection port while holding the engine speed at 2,000 rpm.

16. Upshift to 2nd gear by pressing the paddle shifter +, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port while holding the engine speed at 2,000 rpm.





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

18. 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.

19. Install the air cleaner. Service and Repair






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






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

22. Start the engine, and shift into S.

23. Upshift to 3rd gear by pressing the paddle shifter +, and measure the 3rd clutch pressure at the 3rd clutch pressure inspection port while holding the engine speed at 2,000 rpm.

24. Upshift to 4th gear by pressing the paddle shifter +, and measure the 4th clutch pressure at the 4th clutch pressure inspection port while holding the engine speed at 2,000 rpm.

25. Upshift to 5th gear by pressing the paddle shifter +, and measure the 5th clutch pressure at the 5th clutch pressure inspection port while holding the engine speed at 2,000 rpm.





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

27. 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.





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

29. Install the sealing bolts in 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.

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





31. Install the splash shield.
