Is this the tsb to fix the rattling/clicking sound when idle with the clutch disengaged?

I guess that describes a ticking sound. I suppose they would've included something on the line of "the ticking goes away when clutch is depressed..." so i'm thinking its something else. Many people on the forum agree that the rattling you're hearing is normal. Same with '06 owners..
