What are common issues with the automatic transmission in an Audi 80?

I recently noticed some shifting problems with my Audi 80's automatic transmission. I'm not very knowledgeable about cars, so I'm wondering what are some common issues that could be causing this?

The most frequent culprit for shifting problems in an Audi 80's automatic transmission is low transmission fluid. Check your levels and refill if necessary.

Another common issue could be a failing transmission solenoid. If this is the case, it will likely need to be replaced by a professional mechanic.

It's also important to have your transmission flushed and serviced regularly to prevent any buildup of debris or contaminants that could affect its performance.
