How to maintain the transmission of a Ford S-Max?

I just bought a Ford S-Max and I want to make sure that my transmission lasts as long as possible. What maintenance should I do on a regular basis and how often? Any specific fluid recommendations?

Regularly change the transmission fluid and filter every 30,000-50,000 miles or every 2-4 years depending on driving conditions. Use high-quality transmission fluid recommended by Ford.

Pay attention to any warning signs such as difficulty shifting, strange noises, or leaks and get them checked out immediately. Ignoring these issues can lead to costly repairs.
