I have a TCI TH350 street fighter transmission that is rated for 575hp. It is the 9 in tailshaft length with automatic/ manual valve body and a stock depth aluminum pan. I have only put little over 500 miles on it just for breaking in new motor, I have resealed it and put a aluminum pan on it,doesnt leak at all. Also includes a B&M 2000 non lockup stall converter. I'm looking for a beefed up 200r4 in place of this th350. Nothing wrong with it just want overdrive. Willing to negotiate.
