How can I reset the automatic gearbox on my Audi 80?

I recently purchased a used Audi 80 and I noticed that the automatic gearbox is not functioning properly. The gears shift irregularly and sometimes the car gets stuck in neutral. I have tried changing the transmission oil but it did not solve the issue. Any suggestions on how to reset the gearbox?

Before resetting your gearbox, it is important to diagnose the root cause of the issue. Check for any error codes and inspect the transmission sensors and solenoids for any malfunctions.

To reset the automatic gearbox on an Audi 80, you can disconnect the negative battery cable for 30 minutes and then reconnect it. This will reset the transmission control module and may solve the issue.

It is also recommended to perform a transmission adaptation reset after resetting the gearbox. This can be done using a diagnostic tool or by driving the car for at least 10 miles, allowing the car to learn your driving style.
