With Scan Tool

REDUCING PRESSURE ADJUSTMENT (WITH SCAN TOOL)
1. Adjust the PC solenoid so that the kickdown brake pressure is the standard value when activated to 50% duty by the Scan Tool.

Standard value:
275 ± 10 kPa (39±1 psi, 2.8 ± 1 kg/cm2)
Oil pressure change for each turn of adjustment screw:
20 kPa (3 psi, 0.2 kg/cm2)

2. Check to be sure that the reducing pressure (after the adjustment is completed) is within the range of 370-490 kPa (53-70 psi, 3.8-5.0 kg/cm2).

CAUTION: This adjustment should be made at an oil temperature of 70-80°C (160-180°F). If the adjustment is made at a temperature that is too high, the line pressure will drop during idling, with the result that it might not be possible to make the correct adjustment.
