The fuel pump may fail causing the engine to stall and not restart.
The rubber section of an automatic transmission cooler line may develop a fluid leak . In some cases the leaking section of hose can be replaced. In others, the complete cooler line must be replaced to correct this concern.
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.
