AT42 and ATX specs for belt driven power steering

[moizeau]

I need to top up the PS on the van due to a weep on the PS pump and the BOL's states Total AT42. I've got a tub of Total Fluide ATX. This states it's Dexron II whereas AT42 is Dexron III so I'm guessing it isn't compatible?
Could someone confirm this please?
Cheers

Any ideas please before I go and get some AT42?

D3 seems to be a backwards compatible upgrade for D2, so it's slightly higher spec. I doubt it will make any difference in a PAS system where friction is not critical and tolerances are not tight.
