I have a 94 ex shell I put a z6 swap in, when I started the car I noticed a loud knocking noise coming from the transmission that would go away when I pushed the clutch in. I figured it was the ISB so I threw a known good trans in. Now the noise is still there but doesn't go away when I engage the clutch. I swapped out the throwout bearing with the trans just in case so I know that's not the issue. Is it possible the clutch, flywheel, pressure plate or pilot bearing could be causing the knocking? XTD stage 4 6 puck unsprung clutch fwiw. Car will go into gear and drive/shift through all gears without issue and I'm 99.9% sure it's not rod knock.
