Could it be that there's too much oil in the rear end? Just an idea - I don't know what happens when you overfill a Camaro rear end.

BTW, you can determine the year of your Camaro rear end by checking the numbers punched into the front of the axle tube as described here: http://nastyz28.com/2gcog/rearaxle.html#decode
