How often should I change my Ford Fiesta's transmission fluid?

I recently purchased a used Ford Fiesta and I'm not sure when the previous owner changed the transmission fluid. Is it important to change it regularly? If so, how often should I do it? Thanks in advance!

It's crucial to regularly change your Ford Fiesta's transmission fluid to maintain the car's performance and prevent any potential issues down the road. I recommend changing it every 30,000 miles or every two years, whichever comes first.

Personally, I like to change the transmission fluid every 20,000 miles to be safe. It's a small investment compared to potential repair costs in the future.

The Ford Fiesta's owner's manual recommends changing the transmission fluid every 150,000 miles. However, I would suggest doing it more frequently than that, around every 60,000 miles.
