i got a 96 3/4 ton dodge cummins with auto trans. I'm thinking about switch it to manual with NV4500 and use the auto trans for my conversion into a 97 suburban with a 4bt. The think is i don't know whether my trans is 47rh or 47re, is there a way that you can tell. and whether this trans. would work on a 4bt. Both of these are 2wd, your inputs will be greatly thanks.
