I just recently purchased and installed a brand new CC stage 1.5 clutch and lightweight flywheel along with a new master and slave.
It has been about 400 miles since the install and I am noticing a high pitched squealing noise (similar to an old belt) coming from the tranny, and it goes away when I press down on clutch. Would that mean its the throw out bearing or could it be the input shaft bearing?

Any input is appreciated?

 

70 views and noone has any ideas?

It really only does it at idle.

 

did you replace both the throwout and input shaft bearings? did you grease up the throwout bearing?

 

The TOB was greased but the input shaft bearings were not replaced.
