So last weekend we got slamed with a big snowstorm. my truck ran fine until about 2 hours into the storm and my truck wouldnt shift passed second gear. the overdrive button on the shifter started blinking and the check engin light came on. so i went home and let the truck cool down for a couple of hours and went back out and it was fine for another couple of hours then the same thing happened again. now i have been driving it with no problems with the plow off the truck runs great and shifts fine. with a nouther storm comming this week is there anything i can do to stop this problem. the truck has a trans cooler but should i put a bigger one in. any help would br greatly appreciated. The truck is a 2003 F350 7.3 l
