Why does my Audi 80 shift roughly at higher speeds?

I have noticed that when driving on the highway, my Audi 80 tends to shift roughly and hesitate when changing gears. This only seems to occur at higher speeds. What could be causing this issue?

It is possible that your transmission fluid level is low. This can cause rough shifting and hesitation at higher speeds. Check your fluid levels and top up if necessary.

Another potential cause could be a malfunctioning transmission control module. This component is responsible for controlling the shifting in your vehicle. Have a mechanic check it for any issues.
