Z3 3.0i auto gearbox service

[Tiger]

Hello everyone. I very recently bought this nice Z3 3.0i automatic, and I am looking to replace the auto transmission fluid. According to a source, I would need the FEBI BILSTEIN 1001357 Automatic transmission filter kit, but I am unsure about the oil. Can anyone recommend what type of oil is best? Is Dexron III OK? Or shall I go for something like a lifetime oil ETL 704SE? The car is in Hampshire, England. Thanks in advance.

Thank you, this is interesting. It still doesn't suggest oil types though, apart from Dexron III.

Have you tried the Opieoils website? As far as I was aware it was a choice of ATF or Dexron III that is ATF compliant.

You can buy a Febi kit with the oil included .. takes 7 litres

I serviced my 3.0 gearbox and diff and used the following

Diff fluid Motul Gear Comp 74w-140 fully synthetic 2 litres https://www.opieoils.co.uk/p-900-mo...ssion-ls-differential-oil.aspx?variantid=1132
Auto transmission fluid Comma MV ATV fully synthetic 10litres https://www.opieoils.co.uk/p-147573...on-power-steering-fluid.aspx?variantid=246831

I did the diff as I was under the car anyway and replaced every fluid so thought might as well while I am here.

Remember you can only use the bolts once so the Febi kit comes with everything
