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 (see ATF LEVEL CHECK  ).
2. Raise the vehicle, and make sure it is securely supported.
3. Allow the all four wheels to rotate freely.
4. Remove the splash shield.
5. Connect the HDS to the DLC (A).

7. Start the engine in the P position, and warm up to normal operating temperature (the radiator fan comes on).
8. 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 shift lever position other than P or N.
   PRESSURE SPECIFICATION
   
   

   Pressure	Fluid Pressure
   	Standard	Service Limit
   Line (A)	950-1,010 kPa (9.7-10.3 kgf/cm2 , 140-146 psi)	900 kPa (9.2 kgf/cm2 , 130 psi)

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 the new sealing washer, and tighten the bolts 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 1st-hold clutch pressure inspection port (C).

13. Start the engine, in the P position.
14. Shift into the 1 position, and measure the 1st clutch pressure at the 1st clutch pressure inspection port (B) and the 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 the 2 position by pushing the shift lever, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection port (D) while holding the engine speed at 2,000 RPM.
    PRESSURE SPECIFICATION
    
    

    Pressure	Fluid Pressure
    	Standard	Service Limit
    1st clutch (B) 2nd clutch (D)	950-1,010 kPa (9.7-10.3 kgf/cm2 , 140-146 psi)	890 kPa (9.1 kgf/cm2 , 130 psi)
    1st-hold clutch (C)	800-880 kPa (8.2-9.0 kgf/cm2 , 120-130 psi)	760 kPa (7.7 kgf/cm2 , 110 psi)

16. Turn the engine off, 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 the 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. Connect the oil pressure gauge to the 3rd clutch pressure inspection port (E) and the 5th clutch pressure inspection port (G).

20. Start the engine with the transmission in the P position while pressing the brake pedal.
21. Shift to the D3 position, and release the brake pedal; the transmission is in 1st gear.
22. Press the accelerator pedal to increase the engine speed to 2,500 RPM; the transmission shifts into 2nd gear.
23. Release the accelerator pedal; the engine speed decreases to 1,000 RPM with the transmission in 2nd gear.
24. Press the accelerator pedal very slowly so that the engine speed increases to 2,000 RPM in 5 seconds, then hold the accelerator; the transmission shifts into 3rd gear. Measure the 3rd clutch pressure at the 3rd clutch pressure inspection port (E) while holding the engine speed at 2,000 RPM.
25. Shift to the D position; the transmission shifts into 4th gear, then 5th gear. Measure the 4th clutch pressure at the 4th clutch pressure inspection port (F) and the 5th clutch pressure at the 5th clutch pressure inspection port (G) while holding the engine speed at 2,000 RPM.
