How many miles on our 17 CX-5? If it's less than 50K miles, I believe one drain-and-fill should be sufficient.
And thanks for the info to a good source of getting Mazda FZ ATF!
Based off the experience of our high mileage members posts (150k-200k+ miles) none of them touched the transmission..........so I figure 1 drain-fill attempt (apox 4 quarts) spread out every 40-50k miles should safely get us to 200k miles and beyond. The benefit would be 200k miles of smoother operation than without. In my case its only 3 attempts since I don't really keep cars after 150k miles anyways. I move on to new/newer cars.
