I could give you all the figures, but as they say "teach a man to fish", use this calculator:Gear Ratio Calculator
The drop down menu's will have tranny's, transfer cases listed. Once everything calculates it even shows you what each gear ratio is and will give you crawl ratio's, rpm/speed and the ability to compare two setup's side by side.

I do love that calculator. There are a lot of them that are simplier, but none that are near as versatile and complete that I have found. I've used it a number of times designing a driveline.
