Hello yall i was test driving a m6 and was doing a WOT session threw 1,2,3 I was at the top of the 3rd gear shifted it into 4th and the car just reved up seemed like the clutch didnt grab. I pressed in the clutch quickly and shifted out of 4th and placed it backed and it grabbed and pulled hard. What could be the problem could the clutch be on its way out?

 

sounds like a slipping clutch
