Tranny Squeak

My 2001 Gt is squeaking when I drive. When the clutch is pushed in (or if I apply only the slightest of pressure), the squeaking goes away. I had thought it might be the throwout bearing, but I have heard that it would squeak with the clutch in or out if it was the throwout bearing. A service shop had told me that it might be the transmission bearing?

I was wondering if anyone has had the same problem, and if so, what was causing the squeak. Thanks.

I tried lifting the pedel up, but the noise does not go away. It only goes away if I depress the pedel. I still think it is probably the throwout bearing. Thanks for your help.
