Technician A says when diagnosing a torque converter clutch (TCC) solenoid problem, you should use a scan tool to identify any diagnostic trouble codes (DTCs) the powertrain control module (PCM) has identified related to the TCC circuit. Technician B says when checking the resistance of the TCC solenoid through the connector and the resistance is out of specifications, the problem could be the solenoid or wires to the solenoid inside the transmission pan. Who is correct?
