The torque converter clutch can stick "on" after extended freeway driving causing the engine to stall when coming to a stop. Our technicians tell us when this occurs, the engine usually will restart and stall when put into gear. After allowing about twenty minutes for the engine and transmission to cool down, the engine will start and the transmission will operate normally. Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.Google+

Pontiac Sunbird Torque Converter Clutch Can Stick After Extended Freeway Driving
Pontiac Sunbird Problem
Average Mileage: 99,000 mi (70,000 mi - 128,000 mi)
The car would stall after I had driven for a while or at a fast speed. I could turn the car back on in park, but once I put it in drive the car would stall. I took it to several different shops and they all gave me different reasons and they were all wrong. My cousin was the one who figured it out.

My car was bucking and stalling when decelerating towards a stop sign ir traffic light...OR sometimes when in Reverese. I would have to put the car in PARK, keep giving it gas and then PRAYING it would take off when put in D at the light change. At first, they though it was just a vacuum hose leak, replaced that and it DID idle better. Then it did it again when started, put in R and kept ating like it wanted to die/stall when i took off. She always would take off, but not with the normal "ooomph" when engaged in D after sitting in Park or Neutral at the light or stop sign.
The mechanic had it for two days and only stalled ONCE in that time, at which time I was hoping maybe with the vacuum hose being replaced, it may have sucked in moisture, and tried adding a bottle or water remover to the new tank fillup. It did it again twice..once while going down the street and decelerating towards a stop light, again putting in Park, giving it a little gas, and then engaging in drive. Again when slowing down, putting in REVERSE to park.
The mechanic had it two days again with absolutely no problems. Clean air filter, no pressure loss while being monitored that whole time, so fuel pump was assumed to be okay. Something about the way it felt to a master mechanic, he said the disconnect the torque clutch converter and see if that would help, which I'm trying now. Fingers CROSSED..I'm a fenmale who HATES that feeling a stop sign....and stalled.....when I restart and put in gera..will she go?
