Why is it important to regularly check the transmission fluid in my Ford Focus?

I have a Ford Focus and I've heard that it's important to regularly check the transmission fluid. But I'm not sure why. Can someone explain why this is important and how often I should do it?

It's important to regularly check the transmission fluid in your Ford Focus because it ensures that the transmission is properly lubricated and functioning correctly.

Neglecting to check the transmission fluid can lead to costly repairs and even damage to your engine in the long run.

You should check the transmission fluid every 30,000 miles or every 2 years, whichever comes first.
