Why is my Audi A3's transmission making a clunking noise?

I've noticed a loud clunking noise coming from my Audi A3's transmission when shifting gears. What could be the cause of this and how can I fix it?

It's possible that your transmission fluid needs to be checked and replaced. This could be causing the clunking noise. Make sure to bring your car to a mechanic to get it checked and possibly flushed and refilled.

Another potential cause of the clunking noise could be worn out transmission mounts. Check your transmission mounts for any signs of damage or wear and replace them if necessary. This should help reduce the noise.
