OK, So when letting out the clutch especially in reverse and sometimes first form stopped I get a grinding sound I can feel it too. Other wise the clutch seems to work perfectly, noise only happens from stopped in reverse or first. Thinking it might have something to do with the hill holder but I might be totally off. I have felt around underneath for something loose to to avail. It does seem like more of a grind than a rattle. Any suggestions? It does not happen every time but almost all of the time?

Are you sure it's from the clutch, and not somewhere else in the drivetrain, as the car starts moving?

 

Typical problem with hill holder is if it's too tight, it locks the brakes and you can't move. No noise... just stuck car.

 

Other thing to check is that all the bolts are in that hold the tranny to the engine... I had one that would shudder sometimes when launching in 1st gear. When I finally took it apart to put a new clutch in I found that it was missing the lower two bolts, so they could move relative to each other.

Thanks for the reply and no I am not so sure it is coming from the clutch just that I only hear it when letting the clutch pedal out in first and reverse. I will check the engine to tranny bolts as it seems quite possible it could be some sort of loose or missing something? What are the symptoms of a throw out bearing going bad? Thanks again for any and all help.

TOB going bad will do exactly what you said, so will bearing/bushings inside the trans. most likely the TOB.

It could be exhaust rattle. My legacy was doing this, it would make a horrible rattle only when the engine was under load at about 1000 RPMs, and generally that's only when taking off from a stop.

If I was idling along in first and stepped on the gas it would do the same rattle until just above 1000 RPMs and then stop. Which is what tipped me off it probably wasn't the TOB. Which is what I feared. It's worth checking it out.
