    Default Tow/Haul Button

    I have a new-to-me F350 for hauling sap. Should I engage the Tow/Haul button on the gear shift when I'm hauling a load of sap? Is it best of inclines or declines?

    I use mine only for breaking. It saves the truck's brakes. On declines it will stop the truck from gaining too much speed. If you jab the brakes quickly it will downshift the trans and keep you from gaining speed. It works at the 10mph increments. With my 6.8l motor I don't need the higher shift points for climbing hills.

    I use it anytime I haul a load of sap, it's just easier on the tranny. My haul has hills, both up and down, both ways after loading. I still climb about just 400' after loading to get to my turnaround, then I go down 1400-1500' net to the sugarhouse with some rolling hills in between.. When I get to the steepest hill, I shift into M and run the tranny manually, downshifting enough to save the brakes. My downhill auto shift does not work anymore. On that steepest hill, there is a sharp turn about half way down and a stop at the bottom (with a creek across from that stop, years ago a milk tanker found the creek).
    Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
    Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
    Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
    After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.

    I don't haul sap with my truck but if I did I would probably need to use it. It's recommended that you use it anytime that you exceed 75% of your max payload or trailer weight or anytime that your transmission will need to do a lot of shifting. A tank of sap weighs up pretty fast. I could exceed the payload on my 1/2 ton truck with a full 210 gallon tank in the back.

    The tow/haul button should be used anytime when hauling more than a 'normal' load.

    Using tow mode tells the computer that you are, surprise, towing a heavy load. This will set the transmission control module - TCM - to use a different set of shift points. It will also engage extra clutches/bands within the transmission for extra holding power on the planetary gear set. Engine braking will be utilized.

    Uphill and downhill performance will be noticeable.

    When tow mode is used, Adaptive Learning Strategies are not used, so normal driving performance will not be affected.

    If you think it might be necessary - then do it.

    I have been using my tow/ haul with a load of sap most of the time. Seems more in control! F250 with 325 leg tank.

    I've looked all over my 1986 F-350, standard transmissioned sap hauler and I can't find the "Tow/Haul" button anywhere!

    The guy's I know who do have that button like it a lot and use it often.

    Yours comes with an extra pedal, what more could you want?!

    Ok, I'm glad I asked! Thanks for the responses. Now, I need a load of sap to try it out.
