From my experience, I would recommend an oil change every 20,000miles for the Aisin. Bmw state lifetime for the Zf auto box, however Zf themselves came out with a video several years ago to say that is nonsense, correcting the service and filter should take place at 62,000 miles (100,000km).
 
I don't think it was ever 100k. They claim the Zf box is 100k (lifetime), however zf have produced a video to deny that claim. Bmw themselves cant/won't/don't state the actual service interval of the Aisin box, however as far as I have found, Aisin suggest 22km.
