Transmission fluid is the lifeblood of the engine and transmission system. How often it needs to be changed depends on your gear box type, driving style and what type of journeys you tend to use your Audi for.

There are several components in the transmission system and it is important to change the transmission fluid periodically. The fluid acts as both a lubricant and a coolant.

Transmission fluid, whether natural or synthetic, will have its viscosity broken down through everyday wear and tear.

When the viscosity of transmission fluid breaks down, it becomes less efficient, both as a lubricant and a coolant. Therefore, not only will your transmission’s performance be affected but potentially other components such as the engine may also suffer consequential damage.

The frequency is dependent on your driving style and type of journeys (for example, long motorway driving or short start/stop journeys). However, Audi currently recommends the following oil changes for the following transmission or drive systems:
