How often should I change the transmission fluid in a Ford Puma?

I recently bought a Ford Puma and I'm wondering how frequently I should change the transmission fluid. I've heard mixed opinions and I want to make sure I'm taking care of my car properly.

As a car maintenance expert, I would recommend changing the transmission fluid every 50,000 miles or every 4-5 years, whichever comes first. This will help ensure smooth shifting and prevent costly transmission issues.

In my experience, it's always best to refer to the owner's manual for the recommended maintenance schedule. It varies depending on driving habits and conditions.
