What is the best way to maintain the transmission on a Ford Fiesta?

I've noticed that my Ford Fiesta's transmission has been acting up lately. What is the best way to maintain it to prevent any further issues?

Regularly check the transmission fluid levels and make sure to change it every 30,000 miles. Also, try to avoid aggressive driving habits and get your transmission inspected by a professional if any unusual noises or vibrations occur.

One important tip is to avoid changing gears frequently and abruptly when driving. This can put unnecessary strain on the transmission. Also, try to come to a complete stop before shifting gears from reverse to drive.
