Was on highway going up a very steep hill, speed was right at that point where it kept shifting in/out of Overdrive while using cruise control. Got tired of it and popped her into Tow/Haul. Been there all day

Truck acts and feels like a stick shift. Holds RPM's, slows down when you let off the gas...doesn't upshift unless you really need to

I drive 99.99% city at 0-40 mph. Speed limit is 35 mph damn near everywhere. Just wondering if using Tow/Haul all the time is harmful to trans? May or may not kill MPG's. I know a stick truck would get way better MPG's with my daily commute. With my auto trans acting like a stick, has me thinking.btw, a tuned PSD in Tow/Haul is flat out 150% more fun than when in just "D". I've always known that about Ford auto transmissions, but for some reason it just hadn't occured to me with this truck

 

there was another thread about this just a few days ago...Mark K said it was ok and alot of guys do it

 

link? I searched FTE and that's how I found the mod thread. Didn't see anything else relevant

 

FOUND IT!!!!! after 18 pages of looking https://www.ford-trucks.com/forums/1...ot-towing.html

 

awesome. Thanks

I was hoping Mark would chime in. Glad to see he did so on the other thread. Tow/Haul it is for me

now to see how the MPG game plays out

 

I just started doing the same thing with my modular and I am seeing slightly better mileage around town so far. My driving habits are similar with roughly 90% of my driving at 40mph or less. I am also running the tow tune from mike at 5Star and the combination of the two is awesome!! The truck feels like a different animal around town in tow/haul tune and mode!!
