    Thats what water looks like in atf. Most likely filter is clogged with frozen water crystals causing it to aerate the fluid.

    Make sure you don't have any leaks anywhere.

    I know its not the same application but our riding mower at a leaky seal around the filter which caused it to foam up and the machine would run erratically. If you let it sit for overnight it would work fine because the foam would settle down but after a few minutes it was unusable again. Might be what other have said but this was my experience with hydros.

    You can try aircraft hydo oil. Its a low temp oil called ESSO UNIVIS J13, I use that in replace of blizzard oil as blizzard oil is crazy expensive for the amount I need for 3 plows. Or you can just run blizzard oil. I'm not sure what the oil type is the Boss or Fisher Western use. Some oils are just ATF oil and then they add a color dye and call it there own distinct brand and make you pay twice what it worth because it says fisher or whatever on the bottle.

    Mil-H-5606: Mineral base, flammable, fairly low flashpoint, usable from −65 °F (−54 °C) to 275 °F (135 °C), red color
    Aircraft hydraulic oil =BOSS oil
    This stuff is made for the cold as you can see. It is red but it is not ATF , ATF is made to run at temp not cold.

    Water. Change it, running it a couple times and change it again.

    Plows use hydraulic oil with antifreeze basically

    Atf is fine in a pinch, but plow oil works bettwr

    I had wondered about the difference between the plow oil and atf. Thanks.
