1. Make sure the transmission fluid is filled to the proper level (see ATF LEVEL CHECK  ).
2. Raise the vehicle on a lift or apply the parking brake, block the four wheels, and raise the front of the vehicle. Make sure it is securely supported.
3. Allow the four wheels to rotate freely.
4. Remove the splash shield (A).

7. Turn the ignition switch to ON (II), and go to the A/T data list. Make sure the HDS communicates with the PCM. If it does not, go to DLC CIRCUIT TROUBLESHOOTING .
8. Connect the A/T oil pressure gauge to the line pressure inspection port (A). Do not allow dust or other foreign particles to enter the port while connecting the gauge.

9. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
10. Measure the line pressure at the line pressure inspection port in P or N while holding the engine speed at 2, 000 rpm with the shift lever in P or N.
    NOTE: Higher pressure may be indicated if measurements are made in the shift lever positions other than P or N.

    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 , 131 psi)

11. Turn the engine off, then disconnect the oil pressure gauge from the line pressure inspection port.
12. Install the sealing bolt to the line pressure inspection port with a new sealing washer, and tighten the bolt to 18 N.m (1.8 kgf.m, 13 lbf.ft). Do not reuse the old sealing washer.
13. Connect the A/T oil pressure gauge to the 1st clutch pressure inspection port (B) and the 1st-hold clutch pressure inspection port (C).
