I have a 99 dakota 2 wheel drive automatic with a 3.9 V6. Right now it is my commuter and daily driver for a while. I am going to start gathering full size solid axles and all parts I need to do a 4x4 solid axle swap. I am a professional welder and fabricator and I am aware of the extent of this job. I am curious though of what I can do for the transmission? What transmissions with t-case can I swap? Year range? Any advice would be of great help. Thank you all.
