Hi, I'm looking for someone in Sydney that can repair my C5 MM6 gearbox, it jumps out of reverse especially on an incline, do you know of anyone around. Thanks. (M) Kim 0423012243

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:

(I have no experience with either of them.)

Thanks for the info gtc but they were of no help.

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
