How do I know if my Audi 80's transmission fluid needs to be changed?

I recently bought a used Audi 80 and I'm not sure if the transmission fluid has ever been changed. What are some signs that indicate the fluid needs to be replaced and how often should I do it?

Hi John, congratulations on your new Audi 80! It's always a good idea to check the transmission fluid and change it if needed, especially in a used car. Some signs that indicate the fluid needs to be replaced include a burning smell, discolored fluid, or difficulty shifting gears. It's generally recommended to change the fluid every 30,000-60,000 miles, but it's best to consult your car's manual for the specific interval for your model. Hope this helps!
