First, check the transmission fluid levels and look for any leaks. Next, use a diagnostic tool to scan for any error codes. If there are any, research what they mean and how to fix them. If not, it may be best to take your car to a mechanic for a professional diagnosis. They have the equipment and expertise to accurately diagnose the issue.

My friend had a similar issue with their Audi A4 and it turned out to be a faulty solenoid. It's best to have a professional take a look at it, but it's good to have an idea of what the problem could be so you don't get taken advantage of. Look into common transmission issues for Audis and see if any match your symptoms.

Transmission issues can be complex and costly to fix. If your car is still under warranty, take it to the dealership for repairs. If not, do your research on reputable mechanics in your area.
