TCC and related issues
Victim: 1992 Pontias Grand Am
Symptoms: Runs and idles well until it is driven on a warm day. After driving at speeds in excess of 50 MPH and attempting to brake to a stop, the engine chugs and dies. It feels like a standard tranny not having the clutch depressed when coming to a stop. Engine restarts immediately in Park but dies just as fast when shifted into any gear. After attempting to restart and drive like this a few times, the ignition switch refuses to turn over the starter. After letting the car sit for a few hours, it starts and runs well.
Initial thoughts: Stalling appears to be TCC related. The car had been parked for about a year. Before it was parked, it had the second part of the problem on hot days. It would start and run fine until the engine was turned off. Then it would not engage the starter until it sat for a few hours. The engine runs well, no misses, smooth idle, good mileage, good power. When the starter does engage, the car starts quickly and easily.
Question: What could prevent the starter from engaging after driving on a warm day and allow it to work normally after sitting a while?
