REDUCING PRESSURE ADJUSTMENT

WHEN SCAN TOOL IS USED
1. Use the scan tool to force-actuate the pressure control solenoid valve to 50 % duty, and measure the kickdown brake apply pressure at that time. If the kickdown brake apply pressure is not within the standard value, adjust using the reducing pressure adjustment screw.

Standard value: 250-300 kPa (35-43 psi)
Oil pressure change for each turn of adjustment screw: 22 kPa (3 psi)

2. Check to be sure, after completing this adjustment, that the reducing pressure is within the range of 370-490 kPa (51 -68 psi).

Caution
The adjustment should be made at an oil temperature of 70-80°C (158-176°F).

If the adjustment is made at an oil temperature that is too high, the line pressure will decrease during idling, with the result that a correct adjustment cannot be made.
