The Engine May Stall After Extended Freeway Driving

for the Pontiac Sunfire

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.
