Pressure Tests
Tests^ Special Tools Required
- A/T oil pressure gauge set 07406-0020400
- A/T pressure hose, 2210 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. Raise the front of the vehicle, and make sure it is securely supported.
3. Set the parking brake, and block rear wheels securely.
4. Allow the front wheels to rotate freely.
5. Warm up the engine (the radiator fan comes on), then stop it and connect a tachometer.
6. Connect the oil pressure gauges to each inspection hole securely, and do not allow dust or other foreign particles to enter the holes.
7. Start the engine, and run it at 1,500 rpm in P or N position.
8. Measure line pressure at line pressure inspection hole (A) in the P or N position.
NOTE: Higher pressure may be indicated if measurements are made in shift lever positions other than P or N.
9. Turn the TCS switch off.
10. Raise the engine rpm to 2,000 and hold it. Shift to the 1 position, and measure the 1st clutch at the 1st clutch pressure inspection hole (B) and 1st-hold clutch pressure at the 1st-hold clutch inspection hole (C).
11. Shift to 2 position, and measure 2nd clutch pressure at the 2nd clutch pressure inspection hole (D).
12. Hold engine rpm at 2,000, shift to N for 1 second, then shift to D3.
13. Measure 3rd clutch pressure at the 3rd clutch pressure inspection hole (E).
14. Shift to D and measure 4th clutch pressure at the 4th clutch pressure inspection hole (F), then in about 15 seconds, the transmission will shift to 5th gear.
15. Measure the 5th clutch pressure at the 5th clutch pressure inspection hole (G).
16. Bring the engine back to an idle, then apply the brakes to stop the wheels from rotating.
17. Shift to R position. Raise the engine rpm to 2,000, and measure the reverse clutch pressure at the 5th clutch pressure inspection hole (G).
18. Reinstall the sealing bolts with new sealing washers, and tighten the bolts to the specified torque.
TORQUE: 18 Nm (1.8 kgf-m, 13 ft. lbs.)
NOTE: Do not reuse the old sealing washers.
