Reasons for an oil change

When to change the transmission oil?

ZF Aftermarket recommends a transmission oil change for ZF transmissions as indicated in our Lists of Lubricants. However, the characteristics of the oil change under load. For example, the oils age faster at extremely high operating temperatures.

Shorter change intervals are advisable depending on:

  • Driving style and driving profile
  • Making many trips at high speeds
  • Trailer operation
  • Sporty driving style
  • Frequent short-distance trips

Regular oil changes result in:

  • Reduced wear
  • Less abraded material (maintains clutch disks)
  • Maintains the transmission's adaptability

How can an oil change kit contribute to this task?

All components are of ZF OE quality and are immediately available - this saves working time in the workshop and waiting time for the vehicle owner. ZF oil change kits:

  • Contain components in ZF OE quality exclusively
  • Contain all components required for a professional oil change
  • Always contain the corresponding installation instructions
  • Contain ZF transmission oils that perfectly match the respective transmission thanks to special additives

  • Mechatronic replacement

ZF oil change kits are available for ZF-5HP, 6HP, 8HP and other "non-ZF" makes, e.g., Mercedes, VW and Ford.

Here you can find an overview of the supported types of automatic transmissions in our portfolio.

Notes for workshops

Useful information for workshops and vehicle owners

The maintenance intervals of other transmission manufacturers may vary. In any of these cases, please always refer to the instruction provided by the respective automotive manufacturer.

Caution sign

Additives that are added to the oil at a later time – regardless of their type – change the oil in a manner that cannot be calculated and are therefore not permissible.

ZF is not liable for any damage resulting from the use of such additives.
