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.
