Ben, the sign says 6% for 5 miles. I keep the pedal to the metal, but after a bit I have to left off a little as I'm getting above the speed limit off 65mph there. It's 4 lanes and I stay in the second, over one from the fast lane. Trucks creep up the hill and other are cutting each other off to maintain momentum. See a lot of MH's with toads. Going to be up there in a week, I'll check my speed again and RPM's with my ScangaugeII. Nice to have the transmission temperature. This 5 speed 5R110 runs about 10 degrees hotter than my Winnebago with the 4R100. Oh, maybe it's the 4,000 extra lbs?
To keep this on topic, OP don't worry there's plenty of power in that V10 and you'll have the 6 speed transmission too!
