Sorry, paulco, this will not help you but is a question for members.
One of the gripes here in the UK is the non availability of the 1.5 engine fitted with an AUTO box. This is despite cars fitted with this configuration for South Africa are being ( or were ) built alongside the British models at Swindon.
What Australia has I do not know or even were they are produced so it could be that Australian Jazz is fitted with a CVT, however, I thought the CVT was either a 6 or 7 'speed' box.
Is it possible paulco that you have a straight torque convertor auto box transmission? My old Rover auto was a Jatco 5 speed auto built by the Japanese Auto Company as far as I know in Japan. Their steptronic box was used in as well as Rover by BMW, Porsche, Jaguar, Ford and a few others
As I say this is a general question, no help to the original post.
If this lot don't know the answer I will be surprised.
