It being an E70 is pointless in the discussion. The same transmission is used across multiple vehicles. All 8 speeds used by BMW are a ZF; now ZF does have different 8 speed models that deal with how much power they can handle. BMW does use a lower power spec trans in say a 3 series. The F30 uses a 8HP45. The 5 series uses 8HP50. The F01 and E70 uses 8HP70.
Who knows more about the transmission, BMW or ZF?

ZF automatic transmissions are filled with specially developed oils. At very high operating temperatures, the oil ages faster than under normal conditions. Depending on the driving style (e.g., many trips at high speeds or sporty driving), ZF recommends a transmission oil change every 80 000 to 120 000 km, or after 8 years at the latest.
