Now, with that said, Z transmissions have super soft syncros and baulk ring clips that tend to break and fall down into the bottom of the case. This is what actually causes the grinding issues experienced in most older/abused transmissions. It has nothing to do with the strength of the gears.

interesting, never heard, or seen any baulk rings or anything weird in my gearbox though.
