If it's coming from the dash, it's either the tach or the speedo. If your car has a mechanical tach. IF not, speedo. There used to be a shop in Independence MO that rebuilt them, but they're gone. Couple of places online that repair/rebuild, or you can get a reman from one of the vendors.

I disconnected the speedo at the transducer and eliminated the speedo I test drive with it disconnected and sound was still there now there is another cable from the tranny to the transducer it was still hooked up..just wondering if that could be it or a speedo gear in the tranny.
Is my vette stock?? HAHA

Hello, I have an 82 with the same problem I think. Sounds like birds chirping under the dash. Mine may be speedometer related though. I don't hear the sound when the car is idling or when I rev it up. Only when moving. The faster I go the more frequent the chirping. When it is warm outside and/or the car heats up the sound sometimes goes away. I'll be interested what you find out with your problem. Have not had time to look into it on my vehicle.

The speedometer cable from the transducer to the speedo Itself is fine it moves freely and no noise...
