How to fix the transmission issue in a Ford S-Max?

I bought a Ford S-Max and noticed that the transmission seems to be slipping. What could be causing this and how can I fix it?

Based on my experience as a mechanic, it sounds like the transmission fluid could be low or dirty. I recommend checking the fluid level and replacing it if necessary.

I had the same issue with my Ford S-Max and it turned out to be a faulty transmission control module. I suggest taking it to a certified Ford mechanic for diagnosis and repair.

If your Ford S-Max has high mileage, the transmission may need to be replaced. It's a costly repair, but it's better than risking further damage.
