My friend and I completed the Jmod today on his stang, wasn't too difficult at all. We took it out and now it will bark 1-2 a little bit, and it definately shifts harder, but I was expecting it to like break my neck it shifted so hard. We drilled the holes according to this pdf http://www.crownvic.net/tech/4R70Wnotes.pdf
I told him to get a tuner to firm up the shifts even more, anyways I easily recommend the J-mod, its not that hard at all.
