9 Speed ATF change interval?

The 2017 version of maintenance minder I believe just calculates scheduled maintenance based on number of oil changes that have reached 15% before being reset. If you reset it before that the car doesn't count it. Seems the 2018 or 2019 revision worked some of those bugs out and let's you view upcoming maintenance in the menus of the head unit.

ZF publishes a recommended interval for their 8 and 9 speeds in other vehicles and it is typically 60-75k. Fortunately their green tyranny fluid is synthetic and seems to hold up OK.

Do you have AWD? Rear diff will need to be changed too.
 
There are a lot of ZF transmissions running around out there and the ZF8 and ZF9 in Dodge/Chrysler, BMW, and others all use more or less the same drain and fill procedure. I would expect any competent shop to be able to follow the instructions, but for any one who isn't comfortable asking specifics to their mechanic I would just take it to the dealer.
