Well they are probably referring to the TCC (Torque Converter Clutch) solenoid switch that attaches to the break pedal. When pressure is applied to the break it is supposed to disengage the torque converter (as you referred to overdrive). The TCC is supposed to engage at freeway speeds in order to reduce gas consumption, if it doesn't disengage at lower speeds it will stall the car.
Sometimes the switch on the back of the break pedal will share the same harness as your break lights. So disconnecting the switch at this point would eliminate break lights in some cars.
I am not familiar with your vehicle but there is also a wireharness going to the transmission on some cars that will disable the TCC.
I have been told this type of stalling could also be related to the fuel system. I would have fuel pressure checked out for a possible failing fuel pump. If this is the case replace that and the fuel filter.
I'm having similiar problems, but I hope this helps you.
