What is the cause of the Audi 80's rough shifting?

I recently purchased a used Audi 80 and have noticed that it shifts roughly between gears. The car has about 80,000 miles on it and I wanted to know if this is a common issue and what could be causing it.

There are a few potential causes for rough shifting in the Audi 80. One possibility is that the transmission fluid may need to be changed or topped off. It's also possible that there is an issue with the clutch or the transmission itself, which should be inspected by a mechanic.

It's important to consider the age and mileage of the vehicle when experiencing rough shifting. It's possible that the transmission may need to be rebuilt or replaced, which can be a costly repair. I would recommend getting a diagnostic test done to determine the specific cause of the issue.
