Line Pressure

PROCEDURE
1. Drain out the Automatic Transmission Fluid (ATF).
2. Remove the oil pan.
3. Remove the oil filter and oil temperature sensor.
4. Remove the valve body assembly. The manual valve can come out, so be careful not to drop it.





5. 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 higher.

Standard value: 870-890 kPa (124-126 psi).

Oil pressure change for each turn of adjustment screw: 38 kPa (4.6 psi).





6. 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.
7. Replace the O-ring of the solenoid valve connector with a new one.





8. 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.





9. Tighten valve body assembly mounting bolts (10 pieces) to 10-12 Nm (90-102 inch lbs.).
- A bolt: 18 mm (0.709 inch) long.
- B bolt: 25 mm (0.984 inch) long.
- C bolt: 40 mm (1.575 inch) long.
10. Install the oil filter.
11. Install a new oil pan gasket and oil pan, and tighten the bolts.
12. Pour in the specified amount of ATF.
13. Make the oil pressure test. Readjust if necessary.
