it means you need a total rebuild
"Sun" drum is cracked or hub on drum is wiped out. It's not possible to tell that unless it has had a complete tear down.
Grinding is coming from a planet gear, if he's any good with his ears, he's "close" to the problem. As far as where the part failure is.
DragKing's right, it needs a tear down and going through.
Heres a pic, the stock "sun shell" is a weak link in a 700R4 replace it with this known as "The Beast" T.C.I. has these.
