A few other things I just thought to add, I said it doesn't sound like grinding, but I should amend that. It has a bit of a grinding sound, but NOT like gears grinding, definitely not like gears grinding.

I have a mechanical friend that listened and said it sounds like it may be in the main shaft of the transmission. And in regards to the mention of the pilot bearing or the throw out bearing - I honestly don't know what an issue with the pilot bearing would sound like and I don't believe it's the throw out bearing based on where the sound is coming from. The sound seems to be coming from the middle of the car. And it's a loud enough sound that when driving it others can hear it from maybe 100 feet away, which is another reason I had it towed and won't drive it as is because something is obviously going on with it.

Part of my asking was to see if this is a somewhat common ZR1 issue. Also, is the transmission the same that would be found in any other manual c4 corvette? That's something I honestly don't know, but if so then finding parts should definitely not be an issue.

Thanks again for help and thoughts! And I don't guess anyone by any chance knows a reputable corvette mechanic in the Charlotte area do they?
