Check your RPO codes in the glovebox to determine your gearing.

Are you 2WD or 4WD? If 4WD you will need to regear front and rear axles.

Not sure on your gearing vs mine, but anytime I'm driving under a dash indicated 50 or so, I keep the shifter in 3, just so it isn't constantly downshifting of passing or whatnot...I find it's easier to push those heavy ass wheels
