George, thank for the updates on what you found and good job on getting it sorted out. I'm glad you found the issue and were able to get it repaired in time for your rally in the Alps! Post some pictures of the rally if you have a chance!
I agree with Howard, that while the Ultramatics were designed to be shifted from Low to High, there were issues. I use High all the time, I might use low if I was plowing a field!
I think ensuring your throttle valve linkage is adjusted correctly, so your direct drive isn't engaging too soon, provides plenty of get up and go in most circumstances. If you're shifting from Low to High, under heavy load and too aggressively, you may find that your Ultramatic will become a Problamatic!
