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.

Replacing the torque converter clutch solenoid, transmission filter, and fluid will generally correct this issue.
