The transmission fluid in your Audi acts as both a lubricant and a coolant to your transmission system. Wear and tear breaks down the viscosity of this fluid making it less effective and potentially causing damage to other components.
To ensure your gear changes remain smooth your transmission fluid should be changed according to your service schedule. Your nearest Lookers Audi service will be able to tell you when this is if you're not sure.
For more information or to book please contact your nearest Lookers Audi centre.
