Line Pressure

LINE PRESSURE ADJUSTMENT
1. Drain out the Automatic Transmission Fluid (ATF).
2. Remove the oil pan.
3. Remove the oil filter.
4. Remove the oil-temperature sensor.




5. Press the tab of the solenoid valve harness grommet and push in.




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




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-clock-wise, it becomes higher.

Standard value:
870-890 kPa (124-126 psi, 8.9-9.1 kg/cm)
Oil pressure change for each turn of adjustment screw:
38 kPa (4.6 psi, 0.39 kg/cm)




8. Check to be sure that the O-ring is installed on the upper surface of the valve body at the place shown.
9. Replace the O-ring 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 as shown.
Also be careful that the lead wiring isn't caught.
11. Tighten valve body assembly mounting bolts (10 pieces) to 10-12 Nm (100-120 kg.cm, 7.5-8.5 lb.ft).

A bolt: 18 mm (0.709 in.) long
B bolt: 25 mm (1.984 in.) long
C bolt: 40 mm (1.575 in.) long

12. Install the oil filter.
13. Install a new oil pan gasket and oil pan, and tighten the bolts.
14. Pour in the specified amount of ATF.
15. Make the oil pressure test. Readjust if necessary.
