Why is my Ford S-Max's transmission slipping?

I recently bought a Ford S-Max and I've noticed that the transmission seems to be slipping when shifting gears. It's especially noticeable when I'm accelerating on the highway. What could be causing this issue?

It's possible that your transmission fluid is low or needs to be changed. I suggest checking the transmission fluid level and if it's low, adding more or getting a transmission fluid flush.

Another potential issue could be a faulty torque converter. If the torque converter is not functioning properly, it can cause slipping in the transmission. I recommend taking your car to a trusted mechanic to have it checked out.
