Scotty, I got a 2013 Mazda 3, 96,000 miles, when I bought the car back in 2018 it had 65,000-66,000 miles on it, I know that I have to do a Transmission fluid change every 30,000 miles, and I'm not sure if the previous owner did it before or not, Should I do it or not?
I would do to be safe but be careful. There's no direct result of changing the fluid.
Change it now, do not flush, for your own peace of mind.
