Where is the Torque Converter clutch solenoid located on a 2005 Chevy Cavalier Auto Transmission?

Actually, the Torque Converter Clutch Solenoid is located within the transmission housing that is easily accessible through the transmission oil pan. The TCC solenoid may vary in location dependent upon manufacture but generally it is located as aforementioned. It can cause your vehicle to stall if stuck open or close because it controls loads to the engine via your torque converter which is located between the vehicle's engine and transmission. Also, make certain that you attempt to change the transmission fluid and filter before changing the TCC solenoid because that may be your underlying issue. If not, simply reuse your fresh oil and change the TCC soleniod.

It is located inside the torque converter which is located between the engine and transmission. It is what links the engine to the transmission as one rotating assembly.
