How to maintain Audi A4's transmission fluid?

I recently purchased an Audi A4 and I want to make sure I am properly maintaining the transmission fluid. Can you give me some tips on how to do so and when it should be done?

Hi James, congratulations on your new Audi A4! Maintaining the transmission fluid is important to ensure your car runs smoothly. You should check the fluid level every 30,000 miles or every two years, whichever comes first. Make sure to use only Audi-approved transmission fluid and replace it either every 40,000 miles or every four years.
