IMO, the supra's tranny is a lot better tranny than the mitsu's. At around 55k miles on my old 3000gtVR4 tranny the syncro's went bad and i had to replace the tranny. it was paid for by mitsu. I now have 20k miles on my supra 6speed and i have driven it much harder with no problems to date. i did have to have the tranny replaced due to a leaky seal (covered under warranty). and that tranny lasted 40K at bpu levels and track time...
