Current information on transmission maintenance at ZF

I made an appointment yesterday for transmission maintenance at ZF in Friedrichshafen.

For this I got a price list, as well as another leaflet.

ZF says: "Premium oil change ZF car automatic transmission

In the case of oil, it is necessary to change the oil. Is it meaningful?

The 5-, 6- and 8-speed as well as the 4HP20 automatic transmissions from ZF are each specially developed

Is the transmission also flushed ( Tim Ekart method or similar)?

In principle, the transmission is not flushed. A rinsing using the Tim Ekart method with a rinsing fluid is
