I have a friend from the Oldsmobile list that I've known for about 25 years. He's a hot rodder that's been around a while, plus he's a very smart fella, and knows his stuff.
He's located in Phoenix, and I can reach out to him and find out who he would recommend in that area if you are interested.
I'm 20 miles north of Austin, and the guy who started this forum, HACK/Scott Williams, has a buddy here he uses for transmission rebuilds, but I have no idea if he has a '96 core. I'm pretty sure he could rebuild to a high performance spec.
I bought my transmission from Mike (1FAST94) 2 years ago, but he's located in Ohio, not to close to where you listed.
Once again, fill out your user info, it'll help people recommend folks to you by location.
LMK if your interested in the Phoenix recommendation.
