I have a few litres of ATF transmission fluid. Can we use ATF inthe ZF auto boxes?
Since Dexron III is also compatible with ATF does it work the other way round?

Andy Morgan the chap who rebuilds ZF boxes for a living, he's refurbished 2 for me and I am well pleased with the results. Said this
"Fluid choice is up to your budget, you can use fluid that meets Dexron 2 or 3 standard, but if you want the best for it then a fully synthetic ATF is the way to go.
Running temperatures are lower which is good, service life is therefore doubled or tripled depending on use and shifts are a lot smoother.
I shall send a few links over for the synthetic options.
You will need around 9 litres in total and just in case I forget to mention it you must add 1 litre directly into the converter before fitting (it will not come back out ) "
The litre in the TC is only required if it has been refurbished as its impossible to remove it normally.

Attached the official ZF lubrication instruction. On page 6 you find the approved lubricants.

I changed the oil after 100.000 km due to a recommendation of BMW for the ZF 4HP22. The drain volume was appr. 4 l of total 8.2 l oil filling. The rest remains in the torque converter which can't be drained. So the oil change is more or less a dilution.
I used Mobil ATF 220.in my gear box.

Thanks to all. I have just ordered some top up as I lost a little when the converter as taken out.
I drove the car today for the first time, and have to day the ZF is superb!
