How often should I change the transmission fluid in my Nissan GT-R?

I've heard that changing the transmission fluid too often can be harmful, but I don't want to risk damaging my car. How often is best?

As a general rule of thumb, it is recommended to change the transmission fluid every 30,000 miles or every 2 years, whichever comes first.

In the case of high-performance vehicles like the Nissan GT-R, it is best to change the transmission fluid more frequently, around every 15,000 miles or once a year.
