killed transfercase what other would work 911

[Larcis]

I believe i stripped the gears for both hi sets in my transfer case while pulling my tractor and trailor, it made a buzzing and then just spun like the clutch was in. I put it in 4 low and it got me another 20 miles but then started a loud banging and thats when I called for a tow home, this is my work truck so i need to get it up and going asap so any idea's or info on other tc's that would work would be great, truck info in sig.
