Pressure Tests
TestsSpecial 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 the 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.
8. Shift to N or P position, and measure line pressure at the line pressure inspection hole (A).
NOTE: Higher pressure may be indicated if measurements are made in shift lever positions other than N or P.
9. Shift to 1 position, and measure 1st clutch pressure at the 1st clutch pressure inspection hole (B).
10. Shift to 2 position, and measure 2nd clutch pressure at the 2nd clutch pressure inspection hole (C).
11. Shift to P position, then press the brake pedal and hold it.
12. Shift to D4 position, and release the brake pedal (the transmission is in 1st gear).
13. Accelerate the engine to 2,500 rpm (the transmission will shift to 2nd gear).
14. Release the accelerator for more than 5 seconds after the transmission is shifted to 2nd gear; the engine speed will decrease to about 1,000 rpm.
15. Press the accelerator slowly (so it takes at least 5 seconds to raise the engine speed to 2,000 rpm), then hold the engine speed at 2,000 rpm.
16. Measure 3rd and 4th clutch pressure at the 3rd clutch pressure inspection hole (D), and the 4th clutch pressure inspection hole (E), as the transmission shifts from 2nd gear to 3rd gear, then to 4th gear.
17. Install the sealing bolt with a new sealing washer, and tighten the bolts to the specified torque.
TORQUE: 18 Nm (1.8 kgf-cm, 13 ft. lbs.)
NOTE: Do not reuse old sealing washers.
