Transmission service intervals on "sealed" transmissions - Mazda CX-9

I dont know off hand which transmission is in this vehicle, never looked yet but normal servicing guidelines is to drop the pan, change the filter and refill every 25-30k miles regardless of what the owners manual says. There is no such thing as lifetime fluid. You have a nice new vehicle, maintain it properly and it should last you a long time. Routine maintenance is not expensive, replacement of these components is. Good luck with it.
