What are common problems in the Audi 80's gearbox?

I recently purchased an Audi 80 and have been having some issues with the gearbox. I wanted to know what are common problems that other owners have faced and how did they fix it?

One common issue with the Audi 80's gearbox is gear slippage. This can be caused by worn clutch plates or low transmission fluid levels. It is best to have a professional diagnose and fix the issue as soon as possible.

Another common problem is difficulty shifting gears. This can be due to a faulty shift linkage or a worn out shifter bushing. It is recommended to have these components checked and replaced if necessary by a certified mechanic.
