My 2002 Trailblazer suddenly stopped going into any gear at a traffic light. The fluid level is high when I checked it even while the engine is running, it is clear and does not have a burnt smell. There is no noise coming from the pump or anywhere else for that matter. The truck has 170K on it and I don't think that there has been any work done to it at this point. I have only had the truck for about 2 months. Does anyone have any idea what the cause could be?

SOUNDS LIKE THE PUMP OR CONVERTER take cooler line off at radiator and see if fluid comes out when running
