    Mazda ATF FZ - Factory fill removed and tested at 208k

    I smashed my record this past weekend, did a performance driving event and decided to shut it down at 230F as reported by the scan gauge. No idea what is actually dangerous, but I didn't feel very confident pushing past 230. Was driving fine and ECT was staying very reasonable (~205). I am...

    Mazda ATF FZ - Factory fill removed and tested at 208k

    Wow, that is impressive! Two questions for you, how do you track your temperature? How does your ATF temp compare to your coolant temp once everything is warmed up and steady-state? As far as the Magnefine, I love them and ran them on my CR-V most of its life, that car shifted like new when I...

    Mazda ATF FZ - Factory fill removed and tested at 208k

    Funny you should mention that, I am working on an adapter plate for mine to run a magnefine filter and a traditional cooler. I'm currently waiting on a knockoff cooler from china to use as a template for the adapter plate to give a fluid in/out from the transmission. They do seem to run hot...

    Congratulations on your 2016 GT! I am glad to hear the Lubegard is working out for you. I am a total purist when it comes to ATF in cars with very specific callouts. I pretty much always run plain OEM fluid, my Mazda is no exception. They do kill you on the ATF FZ pricing though...

    Mazda ATF FZ - Factory fill removed and tested at 208k

    Honestly, the report was much better than I expected given the age of the fluid. I expected to see much higher wear metals. Shift quality was wacky. I still think lifetime fluid is a silly concept. That being said, I don't think I could make an argument that leaving this fluid in for 208k had...

    Mazda ATF FZ - Factory fill removed and tested at 208k

    Hey BITOG, I have always been interested in "lifetime" transmission fluid fills. I think they are bogus. I spent some time as a quality engineer in an AT plant and I became even more convinced that they are bogus. At any rate, I purchased a 2014 Mazda 6 in late 2019 with 208k miles on it and it...
