Speed control Question (Ford Rep Please Advise)

[svfetter]

I tow a 4500 lb boat about 1500 miles every year with my 2011 Expedition. Truck tows great. I have noticed the following. I usually drive by foot using the customary Tow/Haul feature. If I want to rest my leg and use speed control for a while, when I engage it the transmission instantly upshifts to the next higher gear feeling like it has disengaged the Tow/Haul mode even when the dash says Tow/Haul is still active. It does not really create any problem, I just do not want to over heat the transmission by being in too high of a gear.

Any one have any thoughts or experience with this?

Tow/Haul does not inhibit the higher gears. It delays shifting longer. In the old days, towing mode was achieved by turning off O/D. Its a bit different today. I don't know why your tranny stays in a lower gear until you turn on cruise control. It should go into the highest gear, then lock the TC (which can feel like a shift sometimes) as long as you are in "Drive".

Interesting - I was under the impression that in Tow/Haul, that under towing load the trans would remain in the lower gear for more pulling torque. Maybe I am wrong on that. But it does seem strange that when towing it only goes into overdrive when speed control is activated.

Probably because the cruise control will hold it more steady than you can with your foot.

If you have a trans temp gauge you may want to monitor it while in od to see if it rises to an unacceptable reading.
