I have a 1998 2500 SLT SB 24 valve with automatic. From day one I have had trouble with my automatic not going back into first gear when I come to a stop. It is in second gear. To quickly remedy the problem, I cycle the engine off then on again and this always clears up the problem. Dodge has replaced the valve body, the computer, and even my transmission. Yet they have not been unable to fix this annoying problem. It only happens when I am towing my 7500 lb. travel trailer. Does anyone have any ideas as to what is causing this problem? I am about to pull out my hair.
