While pulling a heavy toy hauler up the Sierra"s my truck heated up to 220 degrees and the auto began shifting very hard, like banging into gear. Once it cooled down it shifted normally again. Also a CEL came up withthe fuel delivery system error. I'm back home, still have the cel and the truck is running perfectly. The trans fluid still has good color and no burnt smell to it. Anybody know what fuel system error means?

thats kind of a way the computer sees a pressure, and is expecting something else...... mine threw that one and the list of items to get rid of it included lift pump, which I would try first, cp3, and all 6 injectors.
