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

I have been experiencing some trouble with my Ford S-Max's transmission lately. It seems to be slipping and shifting gears at odd times. What could be causing this and how can I fix it?

It is possible that your transmission fluid levels are low or dirty, causing the shifting issues. I suggest checking and replacing the fluid if necessary.

Another common issue with the Ford S-Max's transmission is a faulty solenoid. This can cause erratic shifting and should be replaced.

I had a similar issue with my Ford S-Max and it turned out to be a faulty shift sensor. I recommend getting it checked and potentially replaced.
