This should answer a lot of questions!

Straight from ZF the manufacturer of the transmission

5-, 6-, 8- and 9-speed as well as 4HP20 automatic transmissions: ZF 5-, 6-, 8- and 9-speed as well as the ZF 4HP20 automatic transmissions are filled maintenance-free with specially developed partially synthetic ATF oils. Maintenance-free fills are intended for normal operating conditions. Especially driving at very high operating temperatures can result in accelerated aging or increased wear of ATF oils. It is recommended, in the event of severe operating conditions, such as:
- frequent highway driving in top speed range
- offensive, sporty driving style
- frequent trailer operation, being above average

oil purification (oil change) on automatic transmissions is recommended between 80,000 km and 120,000 km, or 8 years, depending on the load. 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.
