Yea I had a shift kit and transcooler sent to me from MV Automatics from Adelaide, as part of the SAU group buy. Installed in Hyperdrive as I was doing other things with the car. Forgot how much it was, but you can have a look at it from the group buy section, I think they're still doing it.
As far as Auto shops in perth, I have no idea, would be great to find out because I plan do to other things to the autobox.
