Curious to see if it happens again with your new transmission. It's funny that they claim to have never heard of 1-2 shift grinding issues, because as far I can tell, this problem exists to varying degrees in the E46 M3, Z4M, and E9x M3.

I can't speak to the M3 but when this happened in my Z4M it was also possible to trigger it if you shifted at low RPM. You felt the stick move into position but just did not engage correctly and made a very loud grinding noise that is worse than your typical beat-the-synchro grind.
