When your 4l60e’s TCC solenoid begins to fail, there are a number of obvious signs.  The main symptom of a TCC solenoid failure is the converter is not locking up.  When the converter is not locking up you will notice the engine’s RPMs staying higher under load at highway speeds.Â, Another symptom of a failed TCC solenoid is a fault code. My Mech said he will replace the solenoid next week. Different pressure peaks can cause this in the torque converter and the fact that the torque converter slips, as already mentioned. The torque converter is the unit that gently transmits power from the engine to the transmission gears. Torque Converter Clutch (TCC) Solenoid Circuit Electrical This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine. If the torque converter is faulty, it might create unexpected pressures inside the torque converter, which can cause rough idling. Here are the directions for accessing the shift solenoids as well as the TCC solenoid. A widespread problem is that the bearings in the torque converters are worn. If you hear any noises, lift the car and check if other things could be causing the noises before replacing the torque converter.
