2004 4l80e hot trans on hills

Hi my 2004 k2500 transmission gets up to 230f on any grade locked in 3rd gear and not gear hunting. Why is it getting that hot on hills?

My guess is that it might be in 3rd gear and you may even have the gear shift set to "3", but the TC is running 'unlocked' to be able to hold your speed??


PAThwacker, what RPM's are you running when the tranny heats up?
