Im hitting 90k kms,im thinking of changing my ATF very soon as I'm not planning to sell my car until 150k kms at least as its still runs the same way when I got it 8 years ago.

iirc ZF used to recommend a pan drop at 8yrs.

New BMW owner and new forum member here so forgive the (presumably) stupid question - Why not just drain and fill? Why remove/change the pan?

The pan has the filter.

just done a full transmission service at a shop, I can really tell how smoother it feels now. the car has 157000KM - The engine has 3000km that's why I decided to to give her some love

some front/rear diff and transfer case since I was at it...

As mentioned by capt_slow in post#44, the 2021-07-19 ZF doc states 150000 km for ZF ATF service.

If anyone knows of a more recent doc than 2021-07-19, please post on this thread.

bavarianride found it, see attached, February 2021.

ZF 5-, 6-, 8- and 9-speed as well as the ZF 4HP20 automatic transmissions are filled maintenance-free with specially developed
semi-synthetic ATF oils. However, due to the many factors influencing the service life of transmissions in individual operation, ZF
recommends an oil change after 150,000 km for its transmissions. In operating conditions with high temperatures and loads, or
with unknown vehicle use in the past, it can make sense to change the transmission oil at shorter intervals.
In each case, only released ATF oil may be used for oil changes. And oil changes must be performed in accordance with the
relevant specifications. The exception is the ZF 5HP18 automatic transmission which must be filled differently depending on the
version.
