What are the common causes of the Ford Galaxy's transmission failure?

I've been having issues with my Ford Galaxy's transmission and I'm not sure what's causing it. It seems to slip gears and sometimes I have trouble shifting. Any advice on what could be causing this issue?

It sounds like your transmission fluid may be low or dirty. You should check the fluid level and possibly get a transmission flush.

The transmission sensors may be malfunctioning. You may want to take it to a mechanic to have them checked and replaced if needed.

The shifting issues could be caused by a worn out clutch or other internal components. If that's the case, it's important to get it fixed as soon as possible to prevent further damage.
