School me on trans basics

It can and does happen to all flex plates, so the one I posted was just an example.
We didn't need to see it on a Mopar specific plate to show it can happen around the crank where you can't see it with the trans installed.
I agree it can happen to any stock flex plate. I have a Mopar Sfi approved in the race car. I also have one in my 96 ram diesel as the stock one on it failed miserably and it too caused a vibration when it failed. Even though it is only a stock hauler/daily driver it has an upgrade flex plate. Good insurance. Flex plate bolts are always a good application for loctite. I work for an oem car manufacturer, and those bolts always get thread locker.
