    I went to change the fluid in my MM2. When I drained the pump someone put trans fluid in it. My question does it spell trouble using trans fluid in the inew style pumps? I know it was ok in the belt driven pumps. I drained it all out and put Fisher fluid back in.

    Trans fluid will work,I don't like it myself.As long as you flushed the system you will be fine,you don't want to mix fluids if you can help it.

    i found that in my plow too.

    I was thinking about draining it out and using the fisher fluid, but I'm worried about having the small amount of risidual fluid of ATF mixing with the new fluid...

    plow fluid

    Hello...I have a 2007 mm2 v . installed at the local F rep. they use dexron (spelling) III A.T.F. its red.

    if you want to use fishers, you would live where it gets -30 - -45 degrees. and it has nice things in it to prevent bad things from fudging your rams and hoses...

    but the ATF does that too.. just not as well when its -40 out.

    now heres the IMPORTANT thing

    do not be "cool and smart" and buy fisher fluid and top off your fluid. UNTIL YOU KNOW WHAT WAS INSTALLED IN IT.

    mixing the two could be very bad.

    just ask who installed it what they used.

    if its red its atf if its dark/blue its Fisher fluid.

    if you want to switch you need to remove all the old fluid as it states in the manual
    before you install the fisher fluid...

    I just had this conversation with the dealer and man I was glad i asked cause I wanted to be cool and smart and get the good stuff and top it off on the ATF stuff. and that would have sucked !!!!

    cheers
    :nono:

    DJM,
    Your fisher dealer wanted a sale;)
    He wants to be the guy you get your fluid from.
    ATF is a hydraulic fluid It will Mix with the fluid that is in there even the blue stuff will mix and red boss fluid will mix sno-way etc etc...
    Unless you bought expensive synthetic.

    Now,
    Woody,
    No it would not hurt it if there was atf in it. Atf can be used in a pinch.
    It is a wise idea to change your fluid every year.
    It is fairly easy to do your self.
    Just fallow the instructions for your plow.

    It is easy to drain your hoses and rams too.

    It is a good idea to use fisher, Boss, Sno-way or the blue stuff.
    You can also use AW32 hydraulic fluid too all these would be better than ATF.

    Atf will separate when it gets cold. The result is wax(paraffin) will clog your filter.
    Making your plow go even slower.

    I can't believe there's still dealers out there using ATF in brand new plows...

    I drained the pump, hose and ram of the ATF. I pit the Fisher fluid in. i bought 2 extra quarts for stock, so I should be set. Like I had said I use ATF in my speedcast under hood pump for years with no trouble. Just never use the new pump and wanted to be sure. Thanks guys

    The under hood pumps ran in a much warmer inviroment than the "new" style so the cold temps were not much of a factor.
    Pluss you have to do a lot of plowing when it's cold to notice the wax buildup.

    Fisher fluid is fine to use also.;)

    Did you take a look at the filter?
    Sounds like you probably did seeing as you already drained the rams too.

    Now all we need is the white stuff.

    DJM,
    Your dealer should of NEVER put ATF in your new plow. The MM2 plows use low friction cylinders that have exhibited water intrusion when not using the proper stuff. Expect problems.

    I deal with Western though a number of distributors and a couple of them don't even carry the Western fluid.:confused:

    I see brand new plows full of ATF that come out of the local western "specialist" all the time

    Believe it or not,and LON can attest to this,Fluid is not included with a new plow,it is the installer/buyers responsibility.It costs me a little more money but i never send a new plow out the door with anything but the Fisher fluid.I've serviced alot of plows from bigger outfits that still use ATF to this day to save a buck.

    Well my atf is out and the fisher fluid is in. I could waste a call and 20 minutes with the local rep as to why they did that. but I called fisher and explained what happends. and if something fails on the unit. they know what happened. maybe the local place will stop doing that...but when you call them they say atf dexron III or the fisher fluid. they say like with no hesitation,. maybe there just making work for themselves for later... I started late in winter with this plow. I got all the atf out and replaced it. hopefully that should be ok.
