What should tranny temp be ? Was reading 250F at 70mph.(unloaded) Truck is 2002 , 2wd , x-cab , long box. Father in law just bought it , and I know my 6.0l runs alot cooler.
The dash gauges are poop. They go to the middle and stay about any temp. But that is also a possiblity that the sending unit is bad. Does it go to 250 immediatly or does it gradually rise?
