I went to the beach about a 2hour drive over the mountains and up the mountain the truck started smelling like somthing was burning... and the temp gauge which I thought didn't work started climbing a bit, So I guess it was overheating /forums/images/graemlins/smile.gif First thing I need to do is figure out whats wrong with the guage replacing a sending unit is easy but if thats not it then what? i'm thinking of just buying an aftermarket gauge. So around town it doesn't seem to get hot so I'm going to assume that the cooling system isn't that bad. Maybe the tranny getting hot uphill, try a tranny cooler? An auxilerey electric fan??? Any ideas? Thanks!
