Marty, I'm not sure of that bad grade at Monteagle. Jeremiah said he lives pretty close to there so maybe he'll know. There are yellow grade signs going down that grade but I can't remember what the grade is. For years I've shifted from OD down to 3rd to go down the hill watching rpm's but letting the engine help to throttle speed back. And going up, I've crossed that mountain several times pulling campers and I do just as you suggested. I think about that day a bunch, and I still think I didn't over rev. And that bad hill is at the summit going west-east, and it isn't very long, but it is very steep. There are somewhere around two miles of more gentle grade before hitting the monstor summit hill so the motor and trans are pretty hot by the time we get to the last/bad one.
And thanks for the info on flushing or replacing external lines/coolers. I'll have to make certain that happens.

Edit: I just watched the video that Jeremiah pointed out and I don't think the video does justice to the steepness of that bad west-east summit hill. On the video the west-east crossing begins at 47 seconds into the video going up the sligher grades for a few miles, and then the bad/steep summit hill is reached at 1:34 and the top of the summit is reached at 2:00. It's that west-east summit hill where I lost my engine. Jeremiah is this where you lost yours or somewhere else on the mountain?
