  6. Remove the valve body assembly(A). The manual valve can come out, so be careful not to drop it.

  7. Turn the adjustment screw(A) 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 turnedcounter-clockwise, it becomes higher.

    Standard value:

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

    Oil pressure change for each turn of adjustment screw:

    38 kPa (5.4 psi, 0.39 kg/cm2 )

  8. Check to be sure that the O-ring is installed on the upper surface of the valve body at the place.
  9. Replace the O-ring(A) of the solenoid valve connector with a new one.

  10. Install the valve body assembly to the case and then insert the solenoid valve connector into the case. Be sure, at this time, that the notched part of the connector faces. Also be careful that the lead wiring isn't caught.

  11. Tighten the valve body assembly mounting bolts to 10-12 Nm (100-120 kgf.cm, 7-8 lb-ft).
    BOLTS SPECIFICATION

    Bolts Length [in(mm)]
    A 0.98 (25)
    B 1.38 (35)
    C 1.57 (40)
  12. Install a new oil pan gasket with the oil pan(A).

    TORQUE:

    10-12 Nm (100-120 kgf.cm, 7-8 lb-ft)

  13. Pour in the specified amount of automatic transaxle fluid.
  14. Perform the oil pressure test. Readjust if necessary.

REDUCING PRESSURE ADJUSTMENT 

  1. If the Hi-scan tool is not available
    1. Remove parts up to the oil filter in the same way as for adjustment of the line pressure. The valve body need not be removed.
    2. Turn the adjusting screw of the lower valve body and adjust so that the reduction pressure is the standard value.

      When the adjusting screw is turned clockwise, the reduction pressure becomes lower; when it is turned counter clockwise, it becomes higher.

      NOTE: When adjusting the reducing pressure, aim for the center value (425 kPa, 60 psi) of the standard value allowance. 

      Standard value:

      420 kPa (60 psi, 4.2 ± 0.2 kg.cm2 )

      Oil pressure change for each turn of the adjustment screw:

      420 kPa (60 psi, 4.2 ± 0.2 kg.cm2 )

    3. Install the oil filter and oil pan in the same way as for adjustment of the line pressure.
    4. Perform the oil pressure test. Readjust if necessary.
  2. If the Hi-scan tool is used
    1. Adjust the pressure control solenoid so that the kickdown brake pressure is the standard value when activated to 50% duty by the Scan Tool.

    Standard value:

    320±30 kPa (39 ± 1 psi, 3.2 ± 0.3 kg.cm2 )

    Oil pressure change for each turn of the adjustment screw:

    30 kPa (3 psi, 0.3 kg.cm2 )

    CAUTION: This adjustment should be made with an oil temperature of 80 ~ 90° C (176 ~ 194°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.
