    My Western MVP is about 4 years old. Its had the fluid changed once.
    I've noticed the plow getting slower.
    I want to change fluid.
    Can I put in synthetic GM tranny fluid. All the old westerns used to run tranny fluid.
    Whats the best to use.
    What about that blue, aftermarket stuff by SAM.
    I know there's s a screen and filter in there, how do I change those-by simply taking off the reservoir on the bottom of the unit?

    You can use atf you could use SAE10w too..

    temp range for fluids used in your plow.
    (all temps are in Fahrenheit.)

    ATF,............ 0 to 150

    SAE10W ,.....0 to 150

    ISO VG 22.....0 to 125

    SAE5w ........-20 to 100

    MIL-5606......-60 to 90

    UNIVIS j26...-60 to 155

    I would stay away from a fluid that the bottom of the range is 0 as it will be thickening up way before (0) causing you various problems.

    Because there are better fluids than the atf your dealer put in it,
    They do not come with fluid in them from the factory.
    You get what ever the dealer puts in it.

    And atf is a poor choice.

    New old or even if the owners manual calls for atf there are better fluids to chose from. that's why... hummmmm:

    Ps. just becuse it's red does not mean it's atf eather...

    - Hmmm.... Page 23 Ultra mount owners guide

    7. Fill reservoir to top of fill hole with WESTERN® High
    Performance Hydraulic Fluid to -40°F (-40°C), or
    other fluid conforming to Military Specification
    MIL-H-5606A, such as Mobil Aero HFA or Shell
    AeroShell® Fluid 4.


    Mybe you should take a copy to your dealer to read. He obviously does not keep up on his TSBs.Maybe you should look for other inproper cost cutting in his installation and service work.

    I think the dealer used atf for 20-30 years and had no problem so he keeps using it. You spend 4-5k for a plow why not save $2 on getting the right fluid?I don't use atf fluid in my plow but a guy I plow with uses it in his 85 ford. I don't mine the extra 3 dollars for the right fluid.
