Actually I didn't know that. I thought I'd read somewhere in this forum last year that the USA only had 4 speed auto's which is why I thought to emphasise the "Australian". I know mines a ZF but don't know which one as yet. I did know that they also had GM in the USA and your guess that it was for local content sounds plausible.
