- 2021 CX-9 GT AWD
Hello all. My wife just picked up a 2021 CX-9 GT AWD. I've been looking through the owners manual to familiarize myself with the maintenance as I prefer to do all routine maintenance myself. I noticed that the manual says nothing about fluid changes for the transmission, rear diff, and transfer case. I found a page on a Mazda website that says Skyactiv transmission fluid is good for the life of the transmission. Is the same true of the rear diff and transfer case fluids?
I'm highly skeptical that these fluids will last 100k miles or more and still do their job as they should. I've changed these fluids in all vehicles I've owned before, and they were all part of the maintenance schedule for those vehicles. The 2013 Pilot this is replacing had me change rear diff fluid at 12k and 40k, and ATF and transfer case fluid at 30k and 60k.
This is our first Mazda/Skyactiv vehicle, so maybe there's something I'm missing. Thoughts anyone? Grateful for any feedback. Apologies if this has been discussed previously - I did a search and didn't see anything specifically related to my question.
