Repair procedures

Inspection

1.	Switch "OFF" ignition.

2.	Remove the air cleaner. (Refer to Engine Mechanical System - "Air cleaner")

3.	Disconnect the main connector (A).

Measure the resistance between ground terminal (7) and signal terminal (8).

Specification : 3.5 ± 0.2 Ω

Removal

1.	Remove the valve body assembly (Refer to Hydraulic System - "Valve Body")

2.	Disconnect the main harness (A).

Remove solenoid valve support bracket (A) after loosening the bolts.

Tightening torque :

9.8 - 11.8 N·m (1.0 - 1.2 kgf·m, 7.2 - 8.7 lb·ft)

4.	Remove the underdrive clutch control solenoid valve (A).

Installation

1.	Install in the reverse order of removal.

When installing, apply the ATF or petroleum jelly to the O-ring to prevent damage.
