What are the most common transmission problems in a Ford Galaxy?

I have a Ford Galaxy and I've been experiencing some issues with the transmission. It doesn't seem to shift smoothly and sometimes it feels like it's slipping. What could be causing this and what should I do about it?

It's possible that the transmission fluid is low or dirty. Check the fluid level and consider having it changed if it's been a while.

Another common problem is a faulty solenoid or transmission control module. Have these checked by a professional mechanic.
