I've read the symptoms of slipping clutch but I'm not sure I know if that is what my problem is. It's a 2007 MS6 with 70k miles on it. The issue is when I am in 5th or 6th gear and get on the gas not even too hard, the car will rev up high, then catch, and accelerate normally. I read to never go WOT in 5th or 6th gear and I never have but this just under somewhat harder acceleration. It doesn't happen in any of the other gears really. So what I'm wondering is if your clutch can be slipping in just a few gears and not all of them. Thanks for reading this lengthy post.
