Just out of curiousity, if someone was to swap out their stock transfer case (NVG 241 or AutoTrac NVG 246), with say, NP205, would that cause any problems as far as the computer is concerned

I believe there may be a problem with the electric actuator in the front differental other than that I cant think of anything else. Ofcourse your pushbuttons and light will no longer work.

I guess I'm asking is, are the gear ratios in the 205 different than the 241 or 246? And if so, how would one reprogram the truck's computer to operate properly (tranny shifting, speedo/odometer readings, etc)? Or would it even matter????

Did that make any sense?

Yes the gears are different the Np205 is geared 1:96:1 while the Np241C has a 2.72:1 gear ratio. So you will be gearing higher if you did this swap. Also when swapping to a 205 in your model truck you will have to use a Ford 205 for the driverside differental.
The Ford bolt pattern is round with six bolts the old chevy is a hour glass pattern . The newer model 205 cases in the chevys have a round pattern but I do not believe its the same. If you are still interested in going to a Np205 give www.advanceadapter.com a call. They carry an adapter that mates the Ford 205 to a Gm 700r4 and newer 460le it comes with a new shorter than normal shaft for the trannsmission and the adapter is only 4" thick it has a spud shaft built into it with a bearing as well.
