How to maintain the transmission in my Audi A4?

I'm having trouble shifting gears smoothly in my Audi A4. What steps can I take to properly maintain my transmission?

Regularly check and change the transmission fluid as recommended in your owner's manual. Additionally, have a professional mechanic inspect the transmission for any signs of wear and tear.

Make sure to warm up the car before driving in cold weather to prevent strain on the transmission. It's also important to avoid adding too much weight to the vehicle, as this can put strain on the transmission.
