Tranny noises

[camaro_speedemon]

My tranny started making like a rattling noise sometimes when I put it in gear. It rattled the other day when I put it in reverse, it kept rattling until I let my clutch back out. I know it's probably not the clutch because it only has about 30k miles on it. It does it sometimes when I put it in first and third. I don't think it's a syncro, because obviously reverse doesn't have one and secondly it's not grinding. I'm gonna check the tranny fluid this weekend when I jack my car up to change the oil. Does anyone have any idea this is? Could it be my clutch going again? It grabs hard in second, and sometimes third and doesn't slip in 5th.

Come one, someone has to know what could be making this noise. This is the second time I've asked this question and no one has even answered. I let it slide before, but since it's come back, I can't just ignore it, it's a bit unsettling not knowing whats causing it.
