Im having a noise from tranny like a metal to metal whining noise..when on idle it make noise but if i step on the clutch its gone I just recently change my clutch to Centerforce II..You think my new throwout bearing gone bad, input shaft bearing or clutch mis-adjusted? but other than that they all shifts fine on all gears with no noise..pls help..

Sounds more like a throw-out bearing issue than a transmission problem. Mine has a similar issue but it's not particularly bothersome. A mild noise when idling in neutral goes away when depressing the clutch. Not noticeable at all when driving....

if it goes away when you step on the clutch, it's either an input shaft bearing or one of the two countershaft bearings. Not a release bearing or clutch problem.

damn sound like rebuild..
