Weird Transmission Noise
 

Hey everyone, after 5 years of owning my S2k I'm back on the forums because I really need your guy's help.
My 2001 s2k is making this noise (shown in video) about 10 mins after the car has been running. I can put the clutch in and out and sometimes the resonance of it does change, but doesn't full go away. It definitely is coming from the transmission from what I can tell. Has anyone had a similar noise? Any help is truly appreciated, thank you so much!
