Line Pressure Adjustment
Adjustment of Line Pressure1. Drain out the ATF.
2. Remove the oil pan and oil filter.
3. Remove the oil-temperature sensor.
4. Press the tab of the solenoid valve harness grommet and push in.
5. Remove the valve body assembly. The manual valve can come out, so be careful not to drop
CAUTION: Do not let manual valve fail.
6. Turn the adjustment screw of the regulator valve and adjust so that the line pressure (kickdown brake pressure) becomes the standard value. When the adjustment screw is turned to the right, the line pressure becomes lower; when it is turned to the left, it becomes hither.
Standard value: 870 - 890 kPa (124 - 126 psi, 8.9 - 9.1 kg/cm2)
Oil pressure change:
For each turn of adjustment screw 38 kPa (4.6 psi, 0.39 kg/ cm2)
7. Check to be sure that the O-ring is installed on the upper surface of the valve body at the place shown in the figure.
8. Replace the O-ring of the solenoid valve connector with a new one.
9. 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 in the figure. Also be careful that the lead wiring isn't caught.
10. Tighten the valve body assembly mounting bolts (10 pieces) to 10 - 12 Nm (100 - 120 kgf.cm, 7.5 - 9 ft. lbs.)
- A: 18 mm (0.709 inch) long
- B: 25 mm (0.984 inch) long
- C: 40 mm (1.575 inch) long
CAUTION:
Secure solenoid valve and oil temperature sensor harness at locations shown. Especially the pressure control solenoid valve (PCSV) harness must be routed and clamped as shown in the illustration since it is separated from other harnesses. Failure to secure the harness results in its contact with the detent plate or parking rod.
11. Install the oil filters.
12. Install new oil pan gasket and oil pan.
13. Add the specified amount of ATF.
14. Carry out hydraulic test. Readjust as necessary.
