I am installing a 24 valve in my truck and have a trans dilemma i was hoping someone could help me with. the truck has a divorced transfer case, i want to convert to an automatic. I would like to use a 47rh or a 47re. Im wondering if a two wheel trans is short enough to use. or if i have to go 4 wheel transmission and use the dodge transfer case also. I have a nv 4500 in the truck now out of a two wheel drive .
