Forget my other post, this is after more diagnostics.
The screaming sounds like a jet powering up. This is only in 3rd and only at ab0ut 2000 rpms (its non existent below that rpm and turns into a non audible high frequency above 2400ish).
Also it may be related, but when I let my clutch out at idle it makes some gawd awful noise. Once dis engaged its normal. The noise is a grinding type noise.
New clutch time?
