What are the common problems that arise in the transmission of an Audi 80 and how can they be fixed?

I'm experiencing some issues with my Audi 80's transmission and I'm not sure what the problem is. Can someone with experience in Audi 80s provide insight on common transmission issues and potential solutions?

One of the most common transmission issues with Audi 80s is the failure of the transmission control unit. This can lead to transmission slipping, delayed shifting, and even complete failure. To fix this issue, you can either replace the faulty control unit or have it repaired by a professional mechanic.

Another common problem is a leak in the transmission fluid. This can be caused by damaged seals or gaskets, which can lead to low fluid levels and poor transmission performance. It's important to regularly check and replace the transmission fluid if needed to prevent this issue. Also, make sure to fix any damaged seals or gaskets to prevent further leaks.
