How often should I change the transmission fluid in my BMW 7 Series?

I have a 2015 BMW 7 Series and I'm not sure when I should change the transmission fluid. Can you provide some guidance on how often this should be done and any signs that indicate it's time for a change?

Transmission fluid should be changed every 50,000-60,000 miles or every 4-5 years. However, it's always a good idea to check your owner's manual for specific guidelines for your model.

Some signs that it's time to change the transmission fluid include a delay in shifting gears, a burning smell originating from the engine, or any leaks underneath your car.
