I'm having a hard time seeing why this is even being debated. It's tow/haul mode. Use it when you tow/haul. Seems pretty clear to me.

Cant speak for other manufacturers, but Ford recommends Tow/Haul mode for accelerating from a stop, bumper to bumper traffic, terrain with lots of ups and downs, etc. And if you are on mostly flat highway (already at speed) they recommend you turn it off as a way to gain fuel mileage. As I understand it with my truck (6 speed auto, eco boost) the Tow/Haul will keep you in 5th gear, and if you shut if off the truck will then use 6th (which is why you get slightly better fuel mileage). That was what I was told by a Ford Tech.

Doesn't everything get debated???



But I concur....pretty straight forward type of thing!

No. See my response to oakprk above.

Both mine and my mothers EB (one 2011 and one 2013) use all gears regardless of tow/haul mode. I think your Tech might wanna study a little more. Tow/Haul, at least on the Ford's, is NOT an overdrive off button. They would technically have to lock out 5th and 6th to be an overdrive off button, though.

I can concur the statement that the Ecoboost Ford shown in TH mode stays in 5th more than 6th on moderate rolling terrain. Monitoring transmission temp it does run lower in 5th than trying to stay in 6th or hunt between the two all the time. Ultimately it is up to the OP to choose what is best for him.

That is true for the Chevys too. Mine will stay in 5th most of the time when in tow/haul, but it will still get up to 6th, usually on downhills.

My understanding is that in TOW it doe snot shift into overdrive. I use it sometimes, particularly on hills, but I don't see much difference. 2010 Ford F-150 Super Crew Short Bed Crew Cab 5.4L V-8 6-spd auto 2x2 - 9,800 Lbs. towing capacity. Pulling a 2703WS Rockwood Super Lite (6,400 Lbs. dry weight)

THe biggest thing I notice on my '12 Silverado 1500 is tranny temp. When towing up steep grades I like to have the tranny temp displayed. I remember one time I did not have the TH mode on and the tranny was nearing the 212 degree mark. I turned on TH mode and the temp dropped. I do notice shifting pattern changes but not much. I wish the manual shift would work in regular drive mode rather than needing to shift the level to manual shifting. When I ha my Hundai Santa Fe I could manual shift in regular drive so it was easy to anticipate when I needed to downshift to get more power just before a hill.

I always tow in TH mode now. I'd rather not burn up my tranny!
