I bought a 91 K5 that had its manual tranny swapped for a T350 and a 203 transfer case. The tranny is slipping when it gets warm now, so I want to change it for a 700R4 with a NP241 transfer case. I found a website http://www.phoenixhardparts.com Has anyone done business with them? I spoke to the guy on the phone, and he seems to know what he is doing, but what do I know... They have incredibly low prices. I will need an adapter for the new setup. I found one that the seller says is for a 700R4-NP208. Will it fit the 700R4-NP241? Any help will be greatly appreciated. 1991 K5 Heston Class Flagship "From my cold, dead hands"
