I got a 90 m30 with 173K and the tranny is still running fine (knocking on wood.) The life of the tranny will depend on how hard/frequency/duration you upshift/downshfit for a stick and how much you want to be a sport when going from automatic to sport mode. From what I've seen posted here, I've read posts with trannies crappng out from the low to high 100s. At any rate, depending on the reponses you get here, you can always spend a little time and go through the archives to put your own database together.
