    Tranny choice depends on you...........it has (I assume [​IMG]) a 700R4 overdrive in it now if it is automatic. Good to keep if it is in good shape. Lots of posts over the months about reliability of them. But if you can get a properly rebuilt one I would stay with it. Down the road it can be a real benefit on two fronts - a lower first gear (think it is 3.06 vs. 2.70 in a T350) and more importantly the overdrive feature. Let's say you want to run 33 inch tires in the future. You could put 4.56 gears in that thing and run along at 70mph at 2264 rpm. Best of both worlds, low end grunt and freeway rpms low.

    Likewise with your transfer case......depends on your needs and future use of the truck. Mudhog's recommendation of an NP205 is solid............if you want to spend the money on the conversion and need a super strong brute tcase. Otherwise your NP241 or 208 is probably OK if you are not wheeling too hard.

    Hope this helps a little.
