What is the proper way to change the transmission fluid in an Audi 80?

I recently purchased an Audi 80 and am looking to change the transmission fluid. Can anyone provide step-by-step instructions or valuable tips on doing this properly? Thank you!

First, make sure you have all the necessary tools and equipment before starting the process. I would also recommend checking your owner's manual for specific details on your vehicle. When draining the old fluid, double-check that you've properly located the drain plug and let the fluid fully drain. You can also use a transmission fluid flush additive for a more thorough cleaning.
