It's your throwout bearing. Mine has been doing the same thing for a while, and I'm not dropping the tranny just to replace a stupid bearing. If I get a different block or tranny, then I'll do it...but until then, it gets driven like it is. It's been squeaking for a long time, and it's still fully operational.
