so on my 92' d250 2wd, I'm swapping out the a518 for a 47rh. Now the 47rh came from a 4wd truck. will my od unit and tailhousing from my 2wd 518 tranny bolt onto the 47rh? or what options do I have?
The bolt pattern is the same. If your 518 has a mechanical governor in the o/d housing, that should be the same. I've never tried this swap so I don't have any first-hand input.
