2004 Mazda 6s Wagon ATX
Well, i'm sure high temperatures in an ATX (or heavy load/severe usage cycle situation) can be mitigated by using thicker ATF fluid as necessary.I think the PIDs for ATX fluid temps are available on the OBD port (in other words, Torque can read them.)
Assuming so (I have an MTX) check 'em. If you're under 200F in your actual use, ignore it. If over, consider, if you can hook it up, an auxiliary cooler.
Is it as important as it used to be with fully-synthetic ATX fluids? No. But are high temperatures still bad? Yep.
AMEN. We've already had over 2ft of snow where I am and I love every second of it.I'll take Maine winters 8 days a week over desert heat. You couldn't pay me to move out west!
In order to be able to fit a conventional atf cooler, a custom-made aluminum plate would have to be fabricated - and it would go between the existing heat exchanger and the case of the automatic transmission. Longer bolts would be necessary, and a number of O Rings would be necessary. I think said plate would have to be 1-1/4" to 1-1/2" thick. See the attached graphics. I note that two of the graphics relate to a plate that a transmission flush equipment Company fabricated - to be able to run their flushing machine on the Mazda A/T... the flushing of which I thoroughly oppose and many manufacturers oppose. My purpose of including said graphics is to show the captured O-Ring arrangement that would be necessary on the faces of the aluminum plate.While the current ATX has an internal cooler, from looking at the parts and the descriptions; it appears that this mounts an oil-to-water heat exchanger on the transaxle assembly and the hoses are for coolant.
