How do I troubleshoot the gearbox in an Audi 80?

I have noticed some strange noises coming from my gearbox while driving. What steps should I take to identify and fix the issue?

First, check the fluid levels and condition. This could be a sign of low or dirty transmission fluid. If the levels are fine, then it's important to inspect the transmission for any leaks or damage that may be causing the noises. If everything looks good, it could be an issue with the gears themselves.

Another potential cause could be worn-out or damaged bearings in the transmission. If this is the case, it's best to have a professional mechanic inspect and replace them as soon as possible to prevent further damage.

In some cases, the gearbox may just need to be cleaned and lubricated. Make sure to use a high-quality transmission fluid and follow the manufacturer's recommended maintenance schedule to keep your gearbox running smoothly.
