Re: how can you tell when the trottle body or torque converter switch goes out?

Basically, when the torque converter clutch (TCC) solenoid goes bad the converter can act a couple of different ways. Either the torque converter clutch does not lock-up AT ALL which isn't a huge problem. Fuel economy and performance will suffer but it won't kill the engine. OR, the converter clutch will "lock-up" and not release. This can kill the engine when coming to a stop. It has a feeling similar to driving a manual trans car and not pushing in the clutch when coming to a stop, thus killing the engine. The converter will usually release when the engine quits running and the car will start right back up. If the TCC solenoid sticks and stays "locked-up" it will act like you are trying to start a car in gear, and can kill the engine when shifting from Park or Neutral to drive or reverse.
