What is the best way to maintain the transmission of a Ford S-Max?

I recently bought a Ford S-Max and I want to make sure I take good care of it. I've heard that the transmission can be a bit tricky to maintain, so I want to know what the best practices are.

Regularly check and change the transmission fluid according to the manufacturer's recommendations. This will help ensure smooth gear shifts and extend the life of your transmission.

Avoid harsh driving habits and stop-and-go traffic as much as possible. This can put unnecessary strain on the transmission and lead to premature wear and tear.
