I've recently noticed a strange noise coming from my transmission. It sounds almost like a heat shield rattling, but it goes away when I push the clutch. From what I've experienced before, that's usually a sign the input shaft bearing is toast. I've recently gone turbo though, and am wondering if it could be the throw out or any other part of the clutch. Thanks.

 

Sounds like it could be the TO bearing....do you leave your clutch pushed in at lights, or when you are stopped?

 

From time to time. Not a lot though.
