Pressure Test

Special Tools Required 

• A/T clutch 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. Lift the vehicle up on a lift or apply the parking brake, block rear wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Allow the front wheels to rotate freely.
4. Connect the oil pressure gauges to the line pressure inspection hole (A) and 4th clutch pressure inspection hole (B). Do not allow dust or other foreign particles to enter the holes while connecting the gauges.

5. Remove the intake air duct and air cleaner housing, and connect the oil pressure gauges to the 2nd clutch pressure inspection hole (C). Then temporarily install the air cleaner housing and intake air duct.

7. Warm up the engine (the radiator fan comes on), then stop it and connect the HDS to the DLC.
8. Start the engine, and run it at 2,000 rpm in the P or N position.
9. Measure the line pressure at the line pressure inspection hole (A).
   NOTE: Higher pressure may be indicated if measurements are made in shift lever position other than N or P.
   LINE "A" FLUID PRESSURE SPECIFICATIONS
   
   

   Pressure	Fluid Pressure
   	Standard	Service Limit
   Line (A)	900-960 kPa (9.2-9.8 kgf/cm2 , 130-140 psi)	850 kPa (8.7 kgf/cm2 , 120 psi)

10. Shift to the 1 position, and measure the 1st clutch pressure at the 1st clutch pressure inspection hole (D) while holding engine speed at 2,000 rpm.
11. Shift to the 2 position, and measure the 2nd clutch pressure at the 2nd clutch pressure inspection hole (C) while holding engine speed at 2,000 rpm.
12. Shift to the P position, then press the brake pedal and hold it.
13. Shift to the D3 position, press the accelerator pedal to increase the engine speed to 2,500 rpm; the transmission shifts into 2nd gear.
14. Release the accelerator pedal; the engine speed decreases to 1,000 rpm with the transmission in 2nd gear.
15. Press the accelerator pedal very slowly so that the engine speed increases to 2,000 rpm on 5 seconds, then hold the accelerator; the transmission shifts into 3rd gear. Measure the 3rd clutch pressure at the 3rd clutch pressure inspection hole (E) while holding the engine speed at 2,000 rpm.
16. Shift to the D position, and measure the 4th clutch pressure at the 4th clutch pressure inspection hole (B) while holding the engine speed at 2,000 rpm, then in about 15 seconds, the transmission will shift to 5th gear.
17. Measure the 5th clutch pressure at the 5th clutch pressure inspection hole (F) while holding the engine speed at 2,000 rpm.
18. Bring the engine back to an idle, then apply the brake to stop the wheels from rotating.
19. Shift to the R position. Raise the engine rpm to 2,000 rpm, and measure the reverse clutch pressure at the 4th clutch pressure inspection hole (B).

    Pressure	Fluid Pressure
    	Standard	Service Limit
    1st clutch (D)	890-970 kPa (9.1-9.9 kgf/cm2 , 130-140 psi)	840 kPa (8.6 kgf/cm2 , 120 psi)
    2nd clutch (C)
    3rd clutch (E)

    5th clutch (F)

20. If the measurements are out of service limit, problems and probable causes are listed in the table.
    PROBLEMS AND PROBABLE CAUSES
    
    

    Problem	Probable causes
    No or low line pressure	Torque converter ATF pump Regulator valve Torque converter check valve
    No or low 1st clutch pressure	1st clutch O-rings
    No or low 2nd clutch pressure	2nd clutch O-rings
    No or low 3rd clutch pressure	3rd clutch O-rings
    No or low 4th clutch pressure	4th clutch O-rings
    No or low 5th clutch pressure	5th clutch O-rings
    No or low 4th clutch pressure in the R position	Servo valve 4th clutch O-rings

21. Install the sealing bolts with the new sealing washers, and tighten the bolts to the specified torque. Do not reuse old sealing washers.

    Torque: 18 N.m (1.8 kgf.m,13 lbf.ft) 

22. Install the air cleaner housing and intake air duct.
