What are the most common issues with the Ford S-Max's transmission?

I recently purchased a used Ford S-Max and have noticed some strange behavior with its transmission. Sometimes it shifts roughly and other times it seems sluggish. What could be causing these problems and how can I address them?

It's possible that your transmission fluid needs to be changed or topped off. This is a simple and relatively inexpensive fix that should improve your transmission's performance.

Another potential cause could be a faulty transmission control module. If this is the case, it's important to get it checked out by a professional as soon as possible to avoid further damage to your transmission.

Make sure to regularly maintain your transmission by scheduling routine check-ups and fluid changes. This will help prevent any major issues from arising in the future.
