Why is my Ford Fiesta's transmission not shifting smoothly?

I recently bought a used Ford Fiesta and I'm having trouble with the transmission. It seems to be hesitating and not shifting as smoothly as it should. What could be causing this issue and how can I fix it?

It could be a problem with the transmission fluid levels or quality. I recommend checking the levels and possibly getting a transmission fluid flush done.

Another possibility could be a faulty transmission sensor. I suggest taking it to a mechanic to have it diagnosed and replaced if necessary.

Have you noticed any strange noises or vibrations while driving? It could be a sign of worn or damaged clutch components. It's best to have this checked by a professional as soon as possible.
