What is the best way to maintain the Kia Picanto's transmission?

I have a Kia Picanto and I want to make sure that I am taking care of the transmission properly. Can you give me some tips on what I should do to ensure it lasts as long as possible?

Regularly check and change the transmission fluid every 30,000 miles.

Avoid harsh and sudden gear changes to prevent excessive wear and tear on the transmission.

Get your transmission system inspected by a professional mechanic at least once a year.
