From what I've read, I would have to second what fj40Jim said. The H41 came in two different versions (or more), with one having a little bit deeper of a 1st gear. I have a cruiser tranny that howls a bit, but I'm not sure if it is from using a transfer case with 400,000 miles on it and a transition gear with very little wear, if any, or if its a bearing. I've put over 10,000 miles on it and it has never gotten any worse.
