Keisler Engineering Filed for Bankruptcy
I have one. The shop said it was a pain to install, but it seems to work. Granted, it has only been in service, and very limited so far, since October, so it should work fine. I sent in an email to see what happens to warranty claims.
After the shop rebuilding my car recommended I buy the transmission from Keisler, he discovered other vendors that provide better customer service. Live and learn, I guess (the story of my project) :)
