    I posted this on the commercial snow plowing link and got some good responses. Problem is the transmission is overheating with a fisher mc10ft plow (02 f550). Has anyone else had this issue and what to do to correct and prevent another tranny being installed.

    When's the last time it was flushed?

    Has the radiator been replaced?

    How about the tranny cooler?

    There is an external electric fan that can be installed as well as upgrading to a 6.0 cooler.

    First off does it have the plow prep package, second there is a sensor in the tranny somewhere that fails and gives bad readings. If you go to FordTruckforum and search your issue there's pages of reading but most of them said the same thing about the sensor. Fortunately if thats the issue, its a cheap part and very easy to replace.

    Brian makes a point that I was going to mention, is it actually overheating? Or is it just the idiot gauge?

    Even if it is a bad sensor, buy and install a quality 40k gvw rated oil cooler. They are cheap, and a transmission is expensive. The stock cooler is a joke.

    I have a trans gauge on my f-350 I usual run about 160-180 when plowing, that's a 4r100 trans I guess?.

    Same with my truck most of the time. Will stay around 145 if in 2wd and in the lights stuff. Have to go to 4 wheel and get into it about and it will climb and hold at 160. Only goes higher when I'm running down the road strangely with OD off

    More importantly, when was the last time the filter was replaced? A flush is good, but if the filter is plugging up, you will be working the pump harder.
    I change my filter and fluid once a year, whether it needs it or not. If Im going to do a flush, I do that just before I drop the pan and change the filter. That way, im not flushing all the junk that was internal of the transmission into my new filter.

    What GVW filter do you recommend?

    If at all possible, I would like to keep it below CDL.

    If 40k is good, a 45K must be better... Do you not already have a CDL???

    Where do I find a 45k cooler?

    I do have one, but not all my guys do, so I would rather not have the hassle.

    Gay porn? I wasn't aware you could find that on the interweb, sounds like experience talking.
