anyone here weird noise when accelerating??

[jrniehaus]

Recently I have noticed, with the manual trans... when i accelerate,
usually from a roll into second gear, and push significantly on the
gas.... a weird noise is comming from the transmission or something.
Almost sounds like something is loose. It is a metalic type sound.
Not if I put it in first and stop on it, i don't usually hear it, but the
car winds up so quick and loudly maybe it's just not noticeable over
the engine. Mainly if I take off in first, shift a bit early (1500-2k or so)
then put it in second and stop on it, is when this noise occurs.
Is something wrong??
