mine is a 2002 3.0 Auto (UK) and I’m just researching the same thing.
I keep getting shown options for oil rated at dexron III here.
I’m not sure this is correct either.
Sorry

Further research shows the auto transmission
- transmission fluid for GM 5L40E
Shows Dexron VI is the right ATF for the GM
I think you are good

@JonnyBravo Autodoc do a Febi kit with the filter, gaskets and the correct oil. Saves guesswork

Yes the Autodoc kit comes with Dex3 - Dex6 though is a more modern oil with a lower viscosity, higher performance and will last a lot longer but 3 will work fine.
