Why is the Ford Fiesta's transmission making a whining noise?

I've been driving my Ford Fiesta for a few months now, and I've noticed that the transmission has started making a whining noise. It seems to only happen when I'm driving at higher speeds. Is this something I should be concerned about?

It's possible that there is an issue with the transmission fluid or the transmission itself. I recommend taking it to a certified mechanic to get it checked out as soon as possible.

I had the same issue with my Ford Fiesta and it turned out to be a faulty transmission bearing. It's a fairly common issue with this model, but it can be easily fixed by a mechanic.
