Pressure Tests

Special Tools Required 

• A/T oil pressure gauge set 07406-0020400 or 07406-0020401
• 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 the [P  ] or [N  ] position.
8. Measure line pressure at line pressure inspection hole (A) in the [N  ] or [P  ] position.
   NOTE: Higher pressure may be indicated if measurements are made in shift lever positions other than [N  ] or [P  ].
9. Shift to the [1  ] position, and measure 1st clutch pressure at the 1st clutch pressure inspection hole (B) and 1st-hold clutch pressure at the 1st-hold clutch inspection hole (C).
10. Shift to the [2  ] position, and measure 2nd clutch pressure at the 2nd clutch pressure inspection hole (D).
11. Shift to the [P  ] position, then press the brake pedal and hold it.
12. Shift to the [2  ] position, and release the brake pedal (the transmission should be in 2nd gear).
13. Press the accelerator very slowly to increase engine speed to 2,000 rpm gradually over 10 seconds, then hold it at 2,000 rpm for the remainder of the tests.
14. Shift to the [D ₃ ] position (the transmission will shift to 3rd gear), and measure 3rd cluth pressure at the 3rd clutch pressure inspection hole (E).
15. Shift to the [D ₄ ] position (the transmission will shift to 4th gear), and measure 4th clutch pressure at the 4th clutch pressure inspection hole (F).
16. Shift to the [D ₅ ] position (the transmission will shift to 5th gear), and measure 5th clutch pressure at the 5th clutch pressure inspection hole (G).
17. Shift to the [R  ] position, and measure 5th clutch pressure at the 5th clutch pressure inspection hole.

18. Reinstall the sealing bolts with new sealing washers, and tighten the bolts to the specified torque.
