ahh, easier said than done. i was in a group looking at strengthening one part of our tranny (the 4l60), and while we can make parts of it stronger, making the whole thing stronger is no small task - because it can't just be stronger - it has to be warranteeable (is that a word?).
anyhew, my mind was dreaming of 600+ rwhp, and just trying to imagine if that would be possible with one of our cars (where the tranny didn't die in 1 year or so).
on a side note, the torque ratings (ie 4L60 vs 4T60) are *not* on the same scale - the 4T80 is approx able to handle the same amount of torque as the 5L50 or so. which gives me hopes for the future ;o)
oh, and for cost? there'* a 4t80 going on ebay in the next 4 hours. starting bid is 500 bucks, but nobody has touched it. not too shabby - it'* a professional rebuild...
