And djeirlessr isn't that far off on his down hill comment. Going West to east last Spring my mpg was up from 8.5 to 10.2. Had to have been a prevailing tailwind.

Like Maron's post, at times when were on highways that are relatively flat I have T/H off. When off interstates or in hilly environments I turn T/H on. I have experimented with the T/H on and off during a trip and I do see a reduction in my MPG with it on. So that's why I only use it when in situations that would require it. 2006 Toyota Tundra Quad cab with a Hybrid Shamrock 19' wich is about 4500lbs.

Heat is not your engine/trans friend. Use the T/H any time you tow, unless your pulling a utility trailer with you Cub Cadet. Any kind of weight will cause the trans of over heat if running at high rpm straining to keep the pace in the wrong gear. Think back over the years .... you probably had a friend that tried to pull a camper behind a car, and only got halfway on their trip and the trans over headed and had to be replaced. The engine will overheat also trying to pull in the wrong gear. Like some of the above posts, the Trans Control Module will shift according to towing conditions. Watch the Tachometer and your see little change in rpm's at highway speeds.

What the hell did you buy? LOL
Something did ok on my Toyota so I wont complain, But you do have a point with engineers!

Wuff Wuff, the 2013 Tundra Limited has a transmission temperature gauge mounted on the dash and if I'm not mistaken something special to do with extra cooling for the transmission. In my journeys across the hot southwest I've never seen a temperature change when using the t/h function or not using it. So while I understand extra heat is not Good on a transmission performance I don't think the T/h button influences that.

tow/haul does not change any physical parameters, (ie line pressures) it is just throttle and shift pattern modifications. The unit that comes in the Tundra is very good for staying cool. I am running a Torque app with actual temps, and it stays in lock up very well, (keeping temps down) and the factory cooling is also very good. pushing hard with my old trailer (7k lbs) I never got over 208 degrees.
