Inspection of a 904 torqueflite


Here is he 904......the band surface area is higher than the
Un-machined area. This drum is good....no hot spots. -


Another picture of the 904 reverse drum -

And here we have the 999 reverse drum. The un-machined part is higher than the band surface area.
I doubt it came this way. I think it’s seriously worn down.


999.....you can see how far down it is.
-

What would cause the 999 reverse drum to wear this badly.

Also.....aside from this..
I cannot see where any of the metal in that filter came from or why the fluid is so black....which I’m guessin*is metal wear. The magnet was saturated
