The total ATF capacity is approximately 8.5 quarts. But unless your Mazda dealer got proper ATF cooler adapter which is hard to find, and they’re willing to remove ATF/engine coolant cooler, a procedure which is not approved by Mazda, I doubt your dealer can do a real full ATF flush even with the ATF flushing machine. The reason is there’re more than half of the ATF stays in torque converter and valve body, which requires build-in ATF pump to circulate the old fluid out through the ATF flushing machine when that special ATF cooler adapter is installed with engine runningOk. That’s not what I was expecting. How much quarts should they be using for a proper full ATF exchange? I’m going to talk to them about this.
Exactly. Based on how much ATF used, apparently the dealer used the simplest “Dipstick Mode” available on Trans Pro+ X Series flushing machine. They didn’t hook up any ATF cooler lines.⋯
The machine used prevented them from having to uninstall the shroud below to drain the fluid from the pan. They just drained thru the fill port and filled back up there.
It’s definitely beneficial to the transmission. You have 50% of fresh ATF, which is better than 0% no matter what. Many do drain-and-fill once, which has similar effect of fresh ATF content like yours, at about 50K miles.Does that mean the ATF exchange I did today is pretty much useless unless I follow up with another round in the near future? I don’t want to spend another $140 on it unless it is really beneficial to the car and prolongs the life.
There’s an ATF cooler adapter available for Mazda’s SkyActiv-Drive 6-speed automatic if you can find one on the Internet. That could be the only possible way to replace the entire ATF safely with a commercial ATF flush machine. As for a DIYer it would be better off and much easier just do drain-and-fill multiple times if you really want to replace as much ATF as possible.Hello, I read your messages concerning the oil change of the SKYDRIVE automatic transmissions and I would like to do that of my CX3 which will soon have 50,000 km. I would like the oil change to be complete, and in my research I found it to be a drain on a mercedes automatic transmission.
The interesting part of the video is 31 minutes
In fact the person fixes a suction pipe on the hole of the strainer that he removed, and by starting the engine the new oil is sucked in and it drives out the old oil, at the same time another person change the different positions on the gear lever.
Do you think this solution is feasible on Skydrive?
Follow what ruthrj has said above and you’ll be fine. I wouldn’t change ATF filter cartridge at 50K miles either as many had found the filter is very clean when they changed it at much higher mileage. Since you need to take the ATF pan down to replace the filter, doing the old silicon seal clean-up on ATF pan without scratching the surface is PIA. Try to use Mazda OEM ATF FZ as you’re mixing less than half of fresh ATF with old ATF each time you do a drain-and-fill. And never refill the amount of the fresh oil based on the amount you drained out as many have verified Mazda has under-filled ATF from factory. Read the following 2 long threads for ATF change experiences and suggestions especially the 3 documents from Mazda Workshop Manual provided by Anchorman:Ok, thanks for your answer, can you tell me exactly how to do it if I decide to do several oil changes?
I do a first oil change and I replace the filter (strainer), and I have to drive a bit before doing another oil change?
How many km does it take to do a second oil change?
And do we have to replace the filter again?
ATF drain and refill on Skyactiv CX5. (should be similar for other Mazda models)
My local dealer said they use a special suction device to get more fluid out. Not sure how that is done. Maybe Yrwei52 knows. They raise the charge to more than $250 now. Filter, seal and magnet cleanup.
BTW the I have watched how he cleaned up the intake carbon deposit many times. Very tempted to do it myself. Doesn't seem that difficult to do. Hard to find a shop that provide walnut blasting for Skyacrtive. Most shops only do BMW/VW/Audi.
I agree with ruthrj. More than half of the ATF is in torque converter and valve body, and they can’t be drained out no matter what. A commercial ATF flush machine can intercept the old ATF and feed fresh ATF with ATF in circulation by hooking up outside ATF lines to the outer ATF cooler. But Mazda SkyActiv-Drive transmission feeds engine coolant into an ATF cooler piggybacked to the transmission. So unless the Mazda dealer can find a special ATF cooler adapter to have ATF outlets to hook up, there’s no way to flush the ATF entirely and cleanly. Some “special suction device” stil won’t do the job. I believe your dealer will do simple ATF drain-and-fill, may not even replace the ATF filter cartridge unless you can watch them doing the job.ATF drain and refill on Skyactiv CX5.

I'll just again say I traded my 2015 with 106K miles on it, it's first 27.7K were as a rental, and I drove it hard, too, and the transmission was doing great...
