Thanks to this forum, I just completed 2 drain/fill 's on my 16' Mazda 3 (58,000 miles). Observations:

All in all, it was a very worthwhile project. The lifetime claim is laughable, besides the tranny was underfilled from the factory.
Thanks for sharing your valuable experience. It definitely would help those who want to DIY on ATF drain-and-fill. This’s another confirmation that Mazda under-filled ATF from factory! This should be a legit reason to change the ATF and make the ATF to be at correct level in addition to have fresher fluid.

For those that drop the pan. Is the gasket a silicone type?
No gasket. It uses silicon seal from factory although you may be able to find aftermarket traditional cork gasket for the ATF pan.

looks like all generations use the following for the automatic transmission:
Automatic Transmission Gasket Set - Mazda FZ21-22-900B

I couldn't find any third party aftermarket solutions.

Thanks for confirming. Because the dealer told me it was a silicone type and the videos i saw on youtube use the cork type one.

I did a drain and fill on the wife's 2013 last fall. I had the vehicle up and as level as I could possibly get it. I let it drain for 2 hours. I emptied the drained fluid into a leveled and known correctly marked container. The amount drained came to exactly center of the 4 litre (4.23 Qts) mark on the container. I measured 4 litres into a fresh identical container plus an extra 8 ounces (4.48 Qts total) to account for air bubbles and Mazda under filling practices and poured that into the tranny. This ended up checking at just about perfect for the fill so, I called it a day. Dropping the pan may yield a tad more drainage, I would buy at least 5 Qts. if doing so.

Do i also need around 4 quartz of oil if i drop the pan?
Post #276 by Boland01 says he used almost 6 quarts of ATF FZ when he dropped the pan. But based on specs from Mazda, it should take 3.7~5.18 quarts (again, approximate volume in Mazda‘s way) with filter cartridge replacement. This person in his YouTube video in the attached link used 3.57 liters / 3.77 quarts with ATF filter cartridge change. As for the pan gasket, I’d still follow Mazda workshop instruction and use some type of ATF friendly silicon seal like the video shown. The toughest part is to clean up the old factory seal without scratching the sealing surface, the sealing job is much easier even with silicon seal. From my past experience those cork gasket used on ATF pan is too easy to develop leaks.

Guide: ATF Drain/Fill

FW6A-EL for SkyActiv-G FWD and FW6AX-EL for SkyActiv-G AWD.
- Total ATF capacity is 7.8L / 8.24 US quarts.
- Drain-and-fill estimate including filter replacement: 3.5~4.9L / 3.7~5.18 US Quarts.

Thanks for the responses. The dealer is telling me its around 7.8 liters. Seems a lot so i want to confirm it with other owners.

That’s about the total capacity of the transmission they’re quoting, not what drains out of the pan ; )

How can the ATP part listed under the 2015 link apply to 2013-2015 MY's, but the Beck Arnley version applies to all 2013-2018 models? Why wouldn't both parts apply to the same model year range?

Lazy manufacture parts compatibility database updates. If in doubt call ATP directly.

I just noticed that there has been a change in the capacity specs in the 2020 owner's manual vs older ones.
The old capacity for the 2.5L said 7.8 L (8.2 US qt, 6.9 Imp qt). In the 2020 manual it now says 7.8 L (8.2 US qt, 6.9 Imp qt)/8.0 L (8.5 US qt, 7.0 Imp qt), but it doesn't differentiate when one capacity applies over the other

I’d consider than an acceptable range now. I wonder if that’s the difference between min and max on the dipstick or something.
