2nd gear downshift grind
It is actually the inside cone of the Brass Syncro ring that is wore just enough to no longer be able to grab the gear to speed it up.
They start bottoming out against the gear, and then the gear cone and the syncro ring no longer mate up properly to match the rotating speeds so they will slide together easily. 2 different speeds of the parts is what is causing the grind.
The brass syncro ring is the consumable part.
