In 58 years I have seen probably 15 or so, but then I worked in the trans business. :D
My wife and kids went to CA from AZ and the wife calls when they are on thier way back and tells me her Dodge mini van was making horrible clattering noises.
After describing when and at what RPM's the noises were I decided it was a broken flex plate and told her there were not many choices out on the road and to drive it home as long as it kept going.
When she got back we pulled the trans and the entire center was broken out of the flexplate and it had hammered flat spots into the broken edges of the plate and made it all the way back to AZ like that.
It looked kind of like this but worse when it came out.
