For roadracing, an auto tranny is a bad choice. It's all about your application, not an absolute bad-or-good of one tranny over another.

The upgraded auto tt tranny will handle a small or even mid-size (eg. T67) single turbo and moderate boost levels. For high boost and a big turbo (eg. T76+), you'll need either a 6spd or a TH400.

NB: Please consider posting any help requests in a new thread instead of asking me for help privately. About 99.9+% of the time, private help requests end up covering great information that could be very valuable to other forum members. If you have a good reason for needing the help request to be private, I'll consider it. If not, then why not give everyone else the opportunity to pitch in too, and/or learn from the information? Remember, there's no such thing as a dumb question. We're all here to help within this family of Supra owners.
