I think that the condition is "normal". The problem is that the H2 is a very large vehicle and fairly under powered. It only took one long trip for me to figure this out...I put a Whipple supercharger on it and programmed out the torque management and it cured the problem. Going 75 mph in a 6500 lb. vehicle that is shaped like a brick is pushing it. Anything that you can do to increase the power/torque will help, but you have to remove the T/M.
