Talked to the dealership today and salesman said 3:23 is what all they get in has, didnt think they could get 3:73 with the 3.0, not sure he knew what he was talking about. He did say that with the 10 speed trans it would not make much difference the way the gearing in trans was setup. Maybe hes right on that. Would just rather have the lower gear ratio. I think the 3:73 might just come with trailor tow package.
