Hello. Gathering some information for a possible 4x4 frame swap. What needs to be done or even can be done to convert a TH400 from a 2WD truck to work with an NP208 transfer case? My current tranny is good and would like to continue to use it if I go to 4x4 frame. Is finding a donor TH400/NP208 combo enough to get the transmission adapter, etc., to make it all work? Or is there a lot of disassembly required to the transmission needed? Thanks for the help.
