I have a 2012 Mazda CX-9 with "lifetime transmission fluid" and no dipstick or means of checking the fluid. I'd like to keep this vehicle for at least 200k miles, which would be about 12 years.
How often should I change the transmission fluid for my peace of mind and to maximize the life of the transmission? If it helps, the transmission is an Aisin AWF-21 6-speed automatic.
