I couldn't tell you honestly.. I just bought my first car and i'm new to all this stuff haha. I have a 99 GTP with 119,000 miles and bought it with a rebuilt trans. It's been working great. You've just gotta find a trustworthy person to rebuild it so you know they'll do a good job. I had someone screw me over once and we payed for the rebuild then just a couple weeks later we went somewhere else and just bought a whole new trans. I imagine a rebuild is cheaper than a new one. You've just gotta find someone you trust to do it. Get a warranty on it if you can. The guy that did mine gave me one. Make sure you get it on paper and signed though or they'll screw you over if it goes bad.
