Remove the automatic transmission oil pan.
Remove the oil filter.
Pic. 3.77. Oil temperature sensor for automatic transmission
Remove the automatic transmission oil temperature sensor (pic. 3.77).
Pic. 3.78. Solenoid valve harness grommet retainer
Press the clamps on the solenoid harness grommet and push it into the transaxle case (pic. 3.78).
Pic. 3.79. Control valve block
Remove the control valve block assembly (valve body assembly). Range selection valve (manual valve) may fall out so be careful not to drop the valve (pic. 3.79).
Pic. 3.80. Pressure regulator adjusting screw
Turn the pressure regulator adjusting screw and adjust the main line pressure, (applied to the downshift brake (kickdown brake pressure), so that it corresponds to the nominal value (pic. 3.80).
Turning the adjusting screw of the pressure regulator clockwise decreases the pressure in the main line, turning the adjusting screw counterclockwise increases the pressure.
Rated value: 860-900 kPa.
Change in oil pressure with each turn of the adjusting screw: 38 kPa.
Check that the O-ring is properly seated on the top surface of the control valve block.
Replace with a new solenoid harness grommet o-ring.
Install the control valve block into the transaxle case, and then push the solenoid harness grommet into place from the inside. When installing, make sure that the protruding parts of the connector are located as shown in Figure 3.78. Be careful not to pinch the wires.
Tighten bolts of fastening of the block of operating valves in gathering the moment of 10–12 Нм.
Install the automatic transmission oil filter.
Install a new oil pan gasket and oil pan.
Fill in the nominal amount of oil (ATF) in automatic transmission.
Check the pressure in the hydraulic control system of the automatic transmission. Repeat pressure adjustment if necessary.
