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 Adapter 07MAJ-PY40120
• Pressure Gauge Adapter 070AJ-RT4A101

1. Make sure the transmission fluid is filled to the proper level (see ATF LEVEL CHECK  ).
2. Raise the vehicle on a lift, and make sure it is securely supported.
3. Allow all four wheels to rotate freely.
4. Remove the splash shield (see SPLASH SHIELD REPLACEMENT ).
5. Connect the HDS to the DLC (A).

6. Turn the ignition switch to ON (II). Make sure the HDS communicates with the PCM and go to the A/T Data List. If it does not, go to the DLC circuit troubleshooting (see DLC CIRCUIT TROUBLESHOOTING ).
7. Connect the A/T pressure adapter to the A/T pressure hose, then connect the A/T pressure hose to the A/T oil pressure gauge set.

11. Start the engine in P, and warm it up to normal operating temperature (ATF temperature between 122°F and 212°F (50°C and 100°C)).
12. Shift the shift lever to D.
13. With the APP Sensor opening less than 18 % with the HDS in the A/T Data List, measure the low line pressure from the A/T oil pressure gauge.
14. Measure the normal line pressure while holding the engine speed at 2,000 RPM with the shift lever in P or N.
    NOTE: When measuring the normal line pressure, do not measure with the shift lever in other than P or N. An improper pressure may be indicated if measurements are made in P or N.
    LINE PRESSURE AND FLUID PRESSURE
    
    

    Line Pressure	Fluid Pressure
    	Standard	Service Limit
    Low	667-716 kPa (6.80-7.30 kgf/cm2 , 96.7-103.8 psi)	Lower limit: 618 kPa (6.30 kgf/cm2 , 89.6 psi) Upper limit: 765 kPa (7.80 kgf/cm2 , 110.9 psi)
    Normal	1,123-1,172 kPa (11.45-11.95 kgf/cm2 , 162.8-170.0 psi)	1,079 kPa (11.00 kgf/cm2 , 156.5 psi)

15. Turn the engine OFF, then remove pressure gauge adapter (C) from the line pressure inspection port.
16. Install a new sealing bolt to the line pressure inspection port, and tighten the bolt to 20 N.m (2.0 kf.m, 14 lb.ft). Do not reuse the old sealing bolt.

    4th Clutch Pressure Test - Engaging 4th Gear 

17. Disconnect the transmission fluid pressure switch C (4th clutch) connector, and remove transmission fluid pressure switch C (4th clutch).
18. Install transmission fluid pressure switch C (4th clutch) to pressure gauge adapter A, then connect the A/T pressure adapter (B) to pressure gauge adapter A.
