What are the common issues with the automatic transmission in Audi A5s?

I have been experiencing some problems with my Audi A5's automatic transmission. It doesn't shift smoothly and sometimes makes strange noises. I want to know what might be causing these issues and how to fix them.

One common issue with Audi A5's automatic transmission is worn out solenoid valves. These valves control the flow of transmission fluid and when they wear out, it can cause shifting problems. My advice is to have a mechanic check and replace any faulty solenoid valves.
