i have a 2003 mustang gt convertable and i just had a new corbra clutch kit installed and my tranny fluid change but the clutch still makes a little chattering noise but goes away when i push on the clutch its not loud or anything i have to put my head down lower to hear it. the people that put the clutch in said that it is normal and it will go away in about 500 to 1000 miles when the clutch is fully broke in, but also when u rev it up while ur in nuetral it u can also can hear rhe chattering noise to. I am just to find out if this is normal or not .
