Likely overthinking but the list of ATF ZF provides seems to be near useless as most seem to be euro products, the only that seems attainable locally is Delvac ATF 1 which is full synthetic and it seems like some recommendations online are to avoid full synthetic?

What are you guys using ? I have a ZF-80.

Thank you!

There should be a plate on the side of your transmission which will indicate the type, weight & quantity.

A have a ZF63A bolted behind the Cummins 370.
The gear calls for ATF III
I used Delvac ATF synthehtic, but now I've switched to 15-40 oil, same iol as Cummins engine.
Makes changing so much easier using oil vs oil and ATF on a change in both engine and gear
