What is the most common cause of transmission failure in Audi vehicles?

I have noticed several Audi owners report transmission issues, but what is the main source of these problems and how can they be prevented?

The most common cause of transmission failure in Audi vehicles is due to a lack of regular maintenance. Audi recommends changing the transmission fluid every 40,000 miles to prevent any potential issues.

Another common factor is aggressive driving, such as frequent hard acceleration and braking. This puts added stress on the transmission and can lead to premature failure.
