Did you go down on the diff fluid? How was the on power steering? I have had to run 10k at our carpet track to keep from diffing out with 4 gears. Going this high in diff fluid has hurt my rotation. I am going to be playing around with 2 gears as well. Any ideas where to start with fluid weight? Running 7.5t on tight high grip carpet.
