How to replace transmission fluid in an Audi 80?

I have noticed some strange behaviors with my Audi 80's transmission and I suspect it may be due to dirty or low transmission fluid. How can I properly replace the transmission fluid in my car to keep it running smoothly?

First, locate the transmission fluid dipstick under the hood of your Audi 80. Use a funnel to add the new transmission fluid into the dipstick tube, making sure to use the appropriate type of fluid for your specific car model.

It is important to warm up your car before changing the transmission fluid. Let it run for a few minutes, then turn off the engine and wait for it to cool down before beginning.
