Only took a ring gear breaking on launch to start the chain of mayhem….. early 90s and we had NO idea this was even a thing. Low 10 street/strip car that had a 300 kit on it that he never even got to use. Needless to say our 727s always had a good drum in them after that.
I've never heard of a ring gear breaking on a 727 trans. If your drum exploded call A&A and they'll make you a valve body that holds the low band in first, never happen again.
