How often should I change the transmission fluid in my BMW X4?

I just purchased a used BMW X4 and I'm not sure when was the last time the transmission fluid was changed. I want to make sure I maintain the car properly. How often should I change the transmission fluid and why is it important?

It is recommended to change the transmission fluid every 50,000 miles or every 5 years, whichever comes first. However, if you heavily use your vehicle or live in extreme weather conditions, it may be beneficial to change it more frequently.

Changing the transmission fluid is important because it helps to keep the transmission running smoothly and extends its lifespan. Old and dirty fluid can cause wear and tear on the transmission components, leading to costly repairs in the future.
