Re: Which axle 3.08 or 3.42?

Thanks for the info. If you look at the overall ratios, your first gear is lower in your '11. I'm still on the fence here. I've heard that a 3.08 can be a little doggy, but I'd like the better MPG. A friend says his '08 is constantly downshifting at the slightest hill. Can't trust the salesman, he says whatever I want to hear. Seems like a big jump from 4l60 3.73 to 6l80 3.08, but the OA ratios aren't that different in the midrange, just a little lower first and a lot higer sixth. Anyone else?
