Mazda 3 2019 2.0 Skyactiv automatic transmission fluid change

Greetings everyone,

My brother recently bought a 2019 Mazda 3 with the 2.0 Skyactiv engine which has an automatic transmission. My question is how often should the transmission fluid be changed since in the service book the car has passed 90k kilometers and the transmission fluid wasn't changed once.

Any help or insight is more than welcome

Cheers

 

A filter change and pan oil change :
It is past due and should be done every 30K miles from the very beginning.

This would be the least expensive service, and you would be able to see how dirty every will be and wand to what extent. If you take pictures of what you find in the pan as well the valve body some of can give a internet assessment of thoughts about what service to do in addition to the basic pan fluid and filter change.
