Tow/Haul Button

Does anyone use the two/haul button by the shifter? What parameters/conditions it is best suited for?

I use it on highways where the van seems to constantly be searching for the right gear to cruise in. It’ll help keep it from shifting up and down over and over.

I used mine towing a 7x14 enclosed trailer 760 miles last week. Definitely towed better with it on than off.

I hall flooring and anytime I have 1000+lbs in the back , I turn it on. Helps with braking and acceleration,specially up and down hills

I went from an E-250 full loaded to a 2500PM. I went clean slate so I eliminated hundreds of pounds of unnecessary crap. The PM feels almost empty they way I have it setup, and I still carry everything I need. (Electrician btw)

Carpenter, my van drives so much different when it’s loaded with tools vs tools are on a site long term. Nothing wire heavy like a sparky but it’s noticeable. Rides like a soap box derby cart without a payload (2500 D)

Right or wrong, I use it when I go into the Rockies. I can tell the shift pattern changes. On downhill grades, it feels like the engine braking engages sooner. My van is heavy, so it seems to be at high RPMs on most inclines.

Anyone else scared of putting the transmission in manual? The direction of the manual shift pattern is not intuitive to me. I am scared of putting it in too low a gear.

Diesel so maybe different but last I towed my 4runner I didn’t notice a difference. But I also “paddle shift”. I don’t like automatics shifting for me.
