Riding in my buddy 1995 Z28 M6 all stock, when he shifts into 3rd at WOT trans goes boom then a bunch of swishing noises. No gear works and clutch pedal is pulsating when not engaged. When car is just idleing can hear clunking and swishing noises when not doing anything. When trying to move car does nothing but rev like in neutral and lots of burning clutch. Any idea what problem is?

 

Probably clutch.
