  7. Turn the adjustment screw of the regulator valve and adjust so that the line pressure (kickdown brake pressure) reaches the standard value. When the adjustment screw is turned clockwise, the line pressure becomes lower; when it is turned counter-clockwise, it becomes higher.

    1. Standard value:

      860-900 kPa (122-129 psi, 8.77-9.18 kg/cm2 )

    2. Oil pressure change for each turn of adjustment screw:

      38 kPa (5.4 psi, 0.39 kg/cm2 )
