Hey guys, I have an 04 cobra and i missed second gear the other day and all of a sudden i hear this loud screeching noise when i hit the clutch. Smoke was coming from the engine bay, i'm not sure exactly where it came from. When i hit the clutch it feels like its grinding on something. I was able to change gears and drive home. Did i blow out the clutch? or do you guys think it's my tranny?
