So I thot that I had solved the issue with just making sure I was downshifting firm too but its seems to be a deeper problem. I have narrowed it down a little more though. It is definitely happening after a rolling down shift. And it I believe it is only happening when I down shift from third to second and apply serious throttle. This just really started happening on a more consistent basis. It slips out of second gear, and with that God awful clank goes back into third. Super unsettling. Thoughts on what else it could be? thanks, will google ghost shifting.
