    I don't have a clue but wondering what kind of transmission does it have? Geared, hydrostatic, is it possibly hydraulic motor driven?

    I've heard auction companies have mechanics come in to make sure all the equipment is running for the auction. That doesn't mean it's fixed... I really think you would get a better response in the construction forum.

    So, it went from shifting hard into gears to not engaging? What do you mean by "Went to shift, Now has no gears" Does the shifter feel loose? Again, construction form is better for transmission and hydraulics problems, IMHO.

    We really need more information. Sounds strange that its gear drive ("manual shift", "clutch") and hydraulics and trans went out at exactly the same time. Specs on Yanmars newer loaders say they are "hydrostat" transmissions..I'll bet this one is too. Since you had hydraulics then started having shifting problems then eventually everything quit, I am going to speculate whatever was causing shifting problems is what eventually caused the total failure. I don't know a thing about how your trans works but if it were mine and I had to diagnose it this way i'd guess that whatever valve(s)/hydraulic circuit is used to translate flow from forward/neutral/reverse would be a likely candidate in my book with what I know right now.

    Here's some things I'd like to know.
    Was there gears grinding, etc when you said it was hard to get in gear? Can you explain more about that.

    How many gear levers does it have and can you move the shift levers or are they stuck?

    Does it have a "shuttle shift" or similar type forward/reverse shifter separate from the 1st,2nd,3rd gear or Hi range/ Low range type gear shift? I was wondering if that was the lever on the left side of the seat ( don't see one on the steering column and I've never personally driven a wheel loader w/o some kind of quick forward/reverse setup on the column)

    When you try to lift the loader, does it bog the engine down or do you hear anything unusual like a relief valve is opening?

    No hydraulics are often are caused by a relief valve that is stuck open or a pump that has quit working. Can also be caused by obstructed filters or screens. I am going with shifting issues being the root culprit though. Maybe you have an a main relief valve open and that is why you have no hydraulics at all? Could be a shot pump? We'll get to that stuff. Let's get some info first.
