I'm gonna bring it by a shop to check it out. I'll update if we figure out what the issue is.
It shifts just fine so I don't think anything is up with the tranny/clutch but the sound changes when the clutch is depressed.

Video example:


In the comments it is mentioned this is due to a bad alternator diode can anyone with experience confirm or refute this?
It sounds pretty similar to this which sounds like it may different from the OP's problem so I may keep searching or start a new thread. I took a couple vids I can upload after I get off work the should help get to the bottom of it.
