According to the temperature display in the truck the allison seems to averaging 140 - 150 degrees F while towing the monty. While towing up severe inclines like the Rocky Mtns the temperature goes to 180 degrees F. I'm not sure if these are normal average temperatures, but I assume a larger pan wouldn't be of much benefit.
Are other GMC truck owners getting similar temperatures?
