According to many other problems my car is having. It makes this grinding noise when I let the clutch go too fast on first gear or even let it go slowly but push hard on gas. The noise also comes from second gear but I couln't really tell and it also has a really difficult time to shift.. It is not as smooth as other cars I drove. This was going on before my clutch or whatever went out. What is the problem, transmission or the clutch.
