Where are you guys buying this stuff as I have checked a few Mazda sites and they don't have it.
I'm usually getting Mazda parts from my Mazda dealer with 20% off from MSRP. Our previous sponsor Med Center Mazda should have it too. Or try mazdastuff.com used by bob ross.

Spark plug structure looked identical although there seemed to be some different metal coloring on OEM. I was so mad they sent me NGK, I really didn't look at them much beyond wrapping and shipping back!
I did not trust myself to drop the pan and seal - so I had a mechanic do it. It took him some time. The fluid looked worn, but not burnt. I can't comment on color.
I suspect it was under filled from factory. I bought 2 bottle per recommendation on this forum. I chose the more expensive lube since I will not do this same service until 150k and judging how the car was running - that's about the limit. IMO of course.

Parts breakdown from mazdastuff.com (please note they corrected the spark plug mixup right away)

Finally got around to the AT drain & refill at 103K miles. Drained fluid looked like strong coffee! Will repeat two more times with about 1K miles in between. Highway driving is about 65% of my miles. Definitely won't wait so long on any future car with "lifetime" fluid. Transmission seems to shift more smoothly, but could just be me. Wasn't experiencing any issues previously just trying to get the most miles on this vehicle as possible.

You are case study 1, then. Please keep us updated! I wish you'd sent a sample for analysis.

Lol, I dont think we can make you happy Un! I shared my ATF Blackstone analysis showing that the viscosity had fallen out of spec, and was mildly flamed for doing the service at all 🤣

What mileage was this done at?

51k, see this thread first post if you want to see the Blackstone analysis.

Fantastic fluid, but I prefer the piece of mind in changing it every 50k if thats how much it took to thin it out a smidge below spec. Ill go with their guess, must be Florida heat.

I'm at 70k miles, fast approaching 71k.

I'm going to go ahead and look at doing some drain/fills. Don't really feel comfortable dropping the pan and applying the new gasket myself, but figured at least getting some new fluid in there should be a good idea. What like 2 or 3 drain/fills?

From what Ive read, 1 should be enough to restore ATF viscosity. First drain was almost brown, didnt look blue. Color isnt necessarily an indicator of quality as we know, but it drained pretty dark (but blue this time!) when doing the second fill. 2 is probably fine. I did 3 even though that could admittedly be overkill for a lifetime fluid, but gives you the best overall mix of new to old ATF for your effort. A 4th drain and fill adds only a marginal amount of new to old.

I wouldnt drop the pan under 100k and I dont blame you for not wanting to. Pans stuck to a vehicle with silicone are a PITA to remove. I marred the transmission block a little when I dropped the pan to do a drain and fill on my 05 Focus years ago.

My thinking on CX-5 ATF change is exactly like you! Except I may do at most 2X due to my laziness. :)

Yeah it's the removing (cleanly) not applying the silicon seal is PITA! But others had said it's a piece of cake ⋯

Yeah consider me nervous about dropping the pan, so I'll stick with drain and fill.

Starting to shop around for the FZ fluid. Surprised a lot of shops like Med Center don't even list it.

They have spray-on stuff to help remove gasket material. That and with a razor blade it should be not difficult at all.

🤔 not sure on the differnve between options 1 and 2. I remember the dealer gave me the bottle starting with 0000. Was cheaper than $15 a bottle though.

Getting the old silicone seal off with a razor blade was ok, it was actually pulling the pan off my focus transmission that was difficult. I thought using a thin flathead for leverage to pop the pan off would be ok, I was mistaken lol!!! Fun lesson on how steel is harder than aluminum. Got it off but didnt care for the mark it left on the block. You live and you learn!

Always a bad idea to pry it off for chance of gouging mating surfaces. Rubber mallet and a block of wood works pretty good.
