We'll, my story is I have an NV4500 and blown out synchros, I found out price wise I might as we'll just buy a full rebuild kit for $350.00 and do everything. How ever, I keep hearing horror stories about the 4500 synchros hating any kind of fast shifting, so rather then doing shafts and most likely updating my con-fe it to a DD to hold, I considered swaping my truck to a 47rh of some kind, I am building my truck to be a dyno queen/ drag truck in the future. I have been searching the net and here and haven't came up with nothing on manual to auto swaps...who's done it, what should I expect ? just trying to do some homework. -Ethan
