What causes the gear shifting problem in a Ford S-Max?

I recently noticed that my Ford S-Max is having trouble shifting gears smoothly, especially when accelerating. What could be the potential causes for this issue?

One possible cause for the gear shifting problem could be a low level of transmission fluid. Check the transmission fluid level and top it off if needed.

Another reason could be a faulty transmission solenoid. I suggest getting the solenoid checked and replaced if necessary.

In some cases, a clogged or dirty air filter can also cause gear shifting problems. Make sure to clean or replace the air filter regularly.

I experienced a similar issue with my Ford S-Max and it turned out to be a malfunctioning clutch. Get the clutch checked and replaced if needed.
