Not quite sure what your asking... Fluid, change procedure, Maintenance interval.

The X5M 35D have a similar transmission, but not the same trans. The ZF recommended service intervals are the same, the BMW recommended intervals are different. The X5M has a replaceable filter and an aluminum cooling pan. The 35Ds filter is integrated into the trans pan and the whole pan is replaced if you want to replace the trans filter. The fluid is the same between the two.

Everything seemed to go by the book, but when I went to start the car with the initial amount of trans fluid in order to shift through the gears before adding more, the car will not start. It displays,

"Functionality or display of the gear selector position may malfunction. Gearbox position P may not be available. Set parking brake when completely stopped. Engine start may be possible with a delay. It is also possible to engage a gear without depressing the brake pedal."

Nothing works. No gear is indicated. car will not start.

Please help. Thoughts?

Check all of your connections very carefully, probably a plug not fully seated.

Anyone got the link to the correct ZIP kit for our transmissions? I would like to change mine out while doing the solenoids. Thanks.

Thanks for the excellent tutorial, parts info, photos and detailed steps. I see the need to align the shifter “fingers”, but not clear on the bolt used, and its role/function, and retuning to original position after aligned. I’m missing something.
Would you clarify?
Thanks so much.
