I have just purchased a 2015 Mazda 5 with 46,000 miles. I plan to maintain the transmission by changing the fluid every 50-60,000 miles. I drive 112 miles a day 6 days a week so I have a habit of racking up high miles here in Ohio. I was wondering if there was anything else I could do to assist its life span? According to my mechanic the transmission does not have a filter in it, just a screen. Would it be beneficial to add on an external transmission filter or even an external cooler (rather than using the radiator), or would this cause problems later on? - Thanks, Jonathan (JMac) McCormick
I’d just leave it alone and change (never flush) the transmission fluid every 50,000 miles (or the Mazda interval) with the OEM transmission fluid. Baby the transmission to prolong its life as Mazda’s have weak automatic transmissions.
Why fix something that isn’t broken?
If I remember correct it is a "Lifetime" fluid so I will be having it changed on a regular basis. I was mainly just curios if there was anything else I should do to it to it. Thanks

All the best!
You are not really abusing the car by driving it, are you? Isn't that what it is made to do? You are not racing it but doing normal driving and most of it should be highway miles with so many miles driven. If the car cannot stand to be driven you should not have bought it. If it could not stand to be driven they should not have sold it. Claiming "high miles" should have nothing to do with it. High miles is a comparison of what others drive, so did the car salesman tell you the car is only capable of "average use"?
If transmission fluid change is suggested at 50-60,000 miles do they restrict a time limit for those miles? Do they say you must only drive those miles over ten years? If not then driving those miles in one year should be acceptable on the quality of the car.
Other things to do are to maintain all fluids/grease maintenance. Keep quality tires and inspect mechanical quality because of those bad Ohio roads. But that is common sense for all vehicles.
