I've searched for a long, long time, and here's what I've found (disclaimer - I don't know everything).

I have never found the v5mt1 behind a 4d56 or 4g54. I found the v5m31 behind the 4d56 in Europe.

I got most of this info from a set of shop manuals on mitsu manual trannies, which I think I got on mitsubishilinks.com, but I'm not sure fer sure...

Perhaps some of our Ozzie friends could chime in.
