Default Transmission grinding noise. HELP

Hi my 2006 GTO has started making a loud grinding noise in the transmission. When I'm driving the car and rev the engine when the clutch is disengaged (pedal down, trans in gear), the transmission makes a loud grinding noise. It is also hard to get into any gears at high RPM's. I have replaced: mastercylinder, slave & throwout bearing. Clutch is a LS7, has around 5K miles. Thanks for any info.

Assuming you got the hydraulic system bled out thoroughly, its probably a defective LS7 clutch. I always try to steer people away from the LS7 bandwagon, as it really is a finicky clutch. Don't get me wrong, a lot of them work just fine. But, I see way too many of them failing like this.

Would your stage 2 clutch be best for my set up (mods in sig-GTO)?
