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

I recently purchased a used Audi 80 and I have noticed some strange shifting patterns in the transmission. What are some common problems I should be aware of and how can I address them?

The most common issue with transmission in Audi 80 models is a failing torque converter, which can cause rough shifting and slipping gears. It is recommended to have a mechanic inspect and replace the torque converter if necessary.

Another common problem with Audi 80 transmissions is a faulty valve body, which can result in delayed or inconsistent shifting. This can often be repaired by replacing the valve body, but it is important to have a professional diagnose the issue first.

Make sure to also check the transmission fluid regularly and replace it according to the manufacturer's recommended schedule. Low or dirty transmission fluid can cause various issues in the transmission system.
