I've researched high and low about clutch buzz but I don't think that's what I have. The few YouTube videos don't match what I'm encountering, unless I can't truly hear the sounds in these videos. Regardless of gear, when I let off the gas and coast, I hear a wretched "ZZZZZZZZZZZZZZZZZZZ" coming from underneath the car. It's loud, and sounds like a bunch of pissed off wasps in a container. If I open the door and duck down a little it sounds like it's coming from the differential, not so much the transmission?

The sound occurs for a split second as I switch gears as well, pretty much as the shifter moves 70% into it's seat. Is this clutch buzz? It sounds way too loud compared to the videos I've seen. It's unbearable.. especially going through a tunnel.. It sounds LITERALLY like a few thousand Cicadas in full mating season.

It's making me not want to drive the car. I can deal with bearing noise, brake grinding, and valve tick.. but not this. Perhaps it really is clutch buzz.. but it drowns out my exhaust completely even with the 40mm+ UK mod.

 

Clutch buzz. It's pretty obnoxious, but you get used to it. Change to the revised OEM disk and you shouldn't have the issue anymore.

 

Well aside from the obnoxious buzzing, it's making a grinding/scraping sound when in gear, (any gear), and clunking occasionally. I guess it needs a new clutch.

My Prelude never gave me even half these issues =\
