Line Pressure Adjustment

LINE PRESSURE ADJUSTMENT








1. Drain out the automatic transmission fluid.
2. Remove the oil pan.
3. Remove the oil filter.
4. Remove the oil temperature sensor.
5. Press the solenoid valve harness grommet and connector into the transaxle case.








6. Press the catches of the solenoid valve harness grommets and pass the connector through the case hole.





7. Remove the valve body assembly. The manual valve can come out, so be careful not to drop it.





8. Turn the adjustment screw on the regulator valve an adjust so that the line pressure (kickdown brake pressure) becomes the standard value.
When the adjustment screw is turned clockwise, the line pressure decreases; when it is turned to counterclockwise, it increases.
Standard value: 870 - 890 kPa (126 - 129 psi)
Oil pressure change for each turn of adjustment screw: 38 kPa (5.5 psi)





9. Check that the O-ring is installed on the upper surface of the valve body at the place shown in the figure.
10. Replace the O-ring of the solenoid valve harness grommet with a new one.








11. Pass the solenoid valve connector through the inside of the hole in the case.





12. Temporarily install the valve body while inserting the detent plate pin in the manual valve groove. Then install the oil temperature sensor and holder and tighten the bolts with the specified torque.
A bolt: 18 mm (0.71 inch) long
B bolt: 25 mm (0.98 inch) long
C bolt: 40 mm (1.57 inch) long
Valve body assembly mounting bolts: 11 Nm (8.0 ft. lbs.)
13. Install the oil filter.
14. Install a new oil pan gasket and oil pan.





15. Pour in the specified amount of ATF.
16. Perform the oil pressure test. Readjust if necessary.
