Inspection

1. | Turn ignition switch OFF.

2. | Disconnect the oil temperature sensor connector.

3. | Measure resistance between sensor signal terminal and sensor ground terminal.

4. | Check that the resistance is within the specification.

Removal

1. | Remove the automatic transaxle assembly. (Refer to "Automatic Transaxle/Repair procedures" in AT group.)

2. | Remove the air breeder hose (A).

3. | Remove the valve body cover (B).

Tightening torque :
12.8 ~ 14.7 N.m (1.3 ~ 1.5 kgf.m, 9.4 ~ 10.9 lb-ft)

4. | Remove the bolt (3ea) after disconnecting the solenoid valve connector (B) and the oil temperature sensor connector (A).

Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

5. | Remove the solenoid valve support bracket (B) and the valve body mounting bolt (A-1ea).

Tightening torque :
9.8 ~ 11.8 N.m (1.0 ~ 1.2 kgf.m, 7.2 ~ 8.7 lb-ft)

6. | Remove the torque converter control solenoid valve (A).

Installation

1. | Installation is the reverse of removal.

After replacement or reinstallation procedure of the valve body assembly, must perform procedures below.

• | Continue to apply liquid gasket at application points at the valve body cover with Ø2.5mm (0.0984in.) thickness.

Liquid gasket Part name :
Threebond 1281B or LOCTITE FMD-546

• | Adding automatic transaxle fluid. (Refer to "Hydraulic system (Fluid)" in this group)

• | Perform TCM learning after replacing the automatic transaxle to prevent slow automatic transaxle response, jerky acceleration and jerky startup. (Refer to "Automatic transaxle control system (Repair procedures)" in this group)
