Notes:

  • Due to the many factors influencing the service life of transmissions in individual operation, ZF recommends an oil change after 150,000 km for its transmission. In operating conditions with high temperatures and loads, or with unknown vehicle use in the past, it can make sense to change the transmission oil at shorter intervals.
