So like I said, I'm currently vehicle-less and I've been looking at 2010-2013 crew cab z71 silverados (LTs) and sierras (SLEs). What I noticed is that with the new 6 speed tranny, they all have 3.42 rear axles except for the VMAXs. What happened to the 3.73s?? I don't know if I can bring myself to buy a 5.3L with 3.43s six-speed or not! HELP!!
