2. Remove the oil pan.
3. Remove the oil filter and oil temperature sensor.
4. Remove the valve body. This may cause the manual control valve to come out, be careful not to drop it.
5. Turn the adjusting screw on the control valve until the system pressure (forced downshift pressure) will not reach the standard value.
When the adjusting bolt is rotated to the right, the pressure in the system decreases, and when it is rotated to the left, it increases.
- Standard value: 870-890 kPa
- Change in oil pressure with each turn of the adjusting bolt: 38 kPa.
6. Verify that the O-ring installed on the top surface of the valve body is located in the location shown in the figure.
7. Replace the solenoid valve connector o-ring with a new one.
8. Install the valve body assembly, then insert the solenoid valve connector into the body. When doing so, make sure that the cutout portion of the connector is positioned as shown in the figure. Also make sure the wire is not pinched.
9. Tighten the valve body mounting bolts to a torque of 10-12 Nm.
- Bolt A: Length 18 mm
- Bolt B: Length 25mm
- Bolt C: Length 40 mm
10. Install the oil filter.
11. Install a new oil sump gasket and oil sump, then tighten the oil sump bolts.
12. Fill in the required amount of automatic transmission fluid.
13. Check the oil pressure in the system. Make adjustments if necessary.
