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 Multi-Use Tester

Standard value:
275 ± 10 kPa (39 ± 1 psi, 2.8 ± 1 kg/cm2)
Oil pressure change for each turn of the 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 (158-176°F).
It the adjustment is made at a temperature that is too high, the line pressure will drop during idling, with the result that is might not be possible to make the correct adjustment.
