'Best' ZF TE-ML 11B fluid available in Aust ?

[tdi-rick]

For a ZF 4HP22EH transmission ?

Castrol Transmax Z has been my go to syn ATF for a very long time.
Is it still the standard for Dex IIIH type fluids ? or are there more modern formulations that surpass it now ?

I ran BG Universal Synthetic ATF in the last two BMWs I owned with the 4HP22.

I think you'd be fine to keep using the Transmax.
