The transmission itself is pretty stout. I just talked to our service manager- he hasn't seen anything on the trans itself, but we have seen 3 cases where the t-o bearing was junk, and one bad disc, all in '07's. '09's, no problems yet, knock on wood
Personally, I won't run anything but stick, and I like the 6-speed. It's not the most precise unit, and the gearing isn't great, but for what it is, it's a solid unit- Mark W.
