Before changing the oil: Read instructions carefully. Check which version (A / B / C) applies to the oil change
ZF automatic transmissions are filled with specially developed semi-synthetic oils.
At very high operating temperatures, the oil ages faster than under normal conditions.
Examples:
Many trips at high speeds
Many trips while towing a trailer
Sporty driving
Depending on the driving style, ZF recommends a transmission oil change every 80,000 to 120,000 km or after eight years at the latest.
