When I had a 95, I bought from "Phoenix" transmission place in Arizona, they also sell through ebay. It had a 6 month warranty. Found a local shop to install it. Soon after, the local shop signed up with Phoenix to install for them.
At 11 months it died. Phoenix had since extended its warranty to 12 months but Phoenix would do nothing for me. All money down the drain. The local shop had canceled its installer agreement with Phoenix because so many of their trannys died under warranty, and the shop had to spend too much labor to take them out, return to Phoenix , wait for replacement, and install again.
The local shop rebuilt it. Had about 70k on their rebuild when I sold it, no problems at all.
Moral: Find a good local shop to rebuild it, get references, make sure they offer a written warranty, make sure it's a warranty through a national organization (ATRA or the other one, I forget the name). Local shops sign up with the organization to guarantee the warranty.
A warranty just from the shop alone is worthless, I learned that the hard way with a Contour I once had. Well I got my money and then some, but it took 4 years of litigation, in both state court and federal court.
