Connect a jumper wire from the negative battery terminal to A/T clutch pressure control solenoid valve A connector terminal No. 2, and connect another jumper wire from the positive battery terminal to A/T clutch pressure control solenoid valve A connector terminal No. 1. Make sure A/T clutch pressure control solenoid valve A moves.
Disconnect one of the jumper wires, and check the valve movement at the fluid passage in the valve body mounting surface. If the valve binds or moves sluggishly, or if the solenoid valve does not operate, replace A/T clutch pressure control solenoid valve A.
Clean the mounting surface and the fluid passage of the transmission housing.
Install a new gasket on the transmission housing, and install the ATF pipe and the ATF joint pipes.
NOTE: Be sure to install a new gasket with the blue side toward the transmission housing.
Install new O-rings over the ATF joint pipes.
Install A/T clutch pressure control solenoid valve A.
Secure the ATF cooler line with the bolts.
Check the A/T clutch pressure control solenoid valve A connector for rust, dirt, or oil, clean or repair if necessary, then connect the connector securely.
