Hey Bump, that trans place is within 20 minutes of me.... My transfer case overheated doing 60 in the early morning Tucson desert. It was probably 65 degrees outside when it happened. I slowed down to 50 for the remaining three days getting home and did not have a problem again. I did toast my seals and had to pull over every 45 mins to an hour to refill. Now I'll cruise about 55 max on the short 15 mile freeway into Portland. It seems to do fine, but its cold outside right now.... The history on the truck is it was being used to refill big diesel tanks including heavy equipment up a rugged 18 mile road for the Smithsonian Institute. It was atop MT Hopkins at the observatory since 1976. So mostly slow continous use..... Roughly 34,000 miles on it.
