Need help with a vibration. I have a 99 Trans Am with 32,000 miles on the clock. It looks as if the Passenger side Cat Converter Section is making contact with the underbody causing a vibration at idle (the interior of the car lights up). It looks as if the tranny is shifted in the mount to one side maybe causing the exhaust contact. My Question, is this a common occurrence when the trans mount is going? The car is 7 years old. Is there something to look for in a bad trans mount? Should I try prying the trans over to pull the exhaust off the underbody? Anybody have any experience with this issue?

By the way the exhaust is stock. Car is stock (except Lid, SFC's)

Thanks in advance for any and all help.
