I was considering that especially because both gm and dodge used the nv4500, so it would make for a very smooth conversion. but wanted to do something different Also I was having trouble finding one. so I was originally going to do a zf6 out of a Chevy because they are sopost to be a very strong trans but I was also having trouble finding one. then this zf5 pretty much into my lap and they are also sopost to be a good reliable trans kind of the predecessors to the zf6 so I went that route.
