Transmission fluid is responsible for both cooling and lubricating sensitive transmission components. Over time, this fluid becomes contaminated by particulate from clutch and gear components wearing down. This contamination reduces the fluid's ability to act as a lubricant, eventually leading to increased wear and tear within the transmission. To prevent excess wear and keep your transmission in top shape, the fluid and filter should be replaced regularly. As per ZF's recommendations, we suggest performing a full service on your 8HP automatic transmission every 50,000 miles. If your vehicle has been modified to produce more power than stock or if it is regularly track-driven, we recommend shorter 30,000-mile service intervals. This will ensure your transmission's fluid is free from contamination, which will help extend the life of internal transmission components, such as clutch packs and solenoids.

The transmission is one of the vehicle’s most vital components, with numerous finely engineered precision parts making it one of the most complex and expensive units to repair or replace. Using the correct oil and replacing it at the correct time is key to preventing transmission problems such as ‘shudder’, gear stiffness, and axle whining. Damaging components before these issues occur can result in possible premature and expensive transmission failure. Only the right oil can guarantee the safe functioning of the transmission in the vehicle. High-quality transmission oils from febi are therefore precisely matched to the special requirements of vehicle manufacturers.
