Steve, I think two had 3.73 and one 4.10. They also put gas to gas and diesel to diesel. As for incline starting, Hummer plant in Mishawaka, IN has a hill about 100' high that is 60% grade. All Hummers come off the assembly line, go to that hill, go half way up, stop, continue over, go half way down and stop, then go on to the storage yard.
