Maybe things are better for them lately - but I've never seen a good review of Monster trannies - I personally would stay away from it. If I were buying prebuilt, I'd have to get a Probuilt - they are a sponsor here, as well as a board member, and I've never seen a foul word about them.

If the tranny is a 1986, I wouldn't rebuild it - GM made some significant improvements in mid year 1987, so I'd snag a 1988+ 700R4 to build or swap in.

 

Sounds like 3-4 clutches are smoked, prob time for a rebuild. I would definitely talk to Dana at Probuilt, he's a stand up guy.
