The MM6 is aka the Tremec T56?

This mob in NSW sells Tremec and may be able to point you to a repairer: https://malexmotorsports.com/collections/tremec-transmission-parts

Maybe also call these guys:

https://www.difftrans.com/services/manual-transmission-repairs-and-parts

(I have no experience with either of them.)
It's C3 chromie for me, see? Si!

The mm6 was originally designed and built by Borge Warner , when gm got involved with it  the box was built by tremec .
Having said that  I see you want a local repair but I?d look at Mal wood in QLD
