You could get some 3.73's or 4.10 gears. Or just slow down or go faster. Personaly I would slow down.

 

I agree i pull a 30' camper to ga every year and i take it out of tow haul while on the flats if i see a hill coming i put it back this works best with a 8,000lbs trailer

 

A good tuner will help but I can not say it will solve the problem. I know my 5.4 can hold gears much longer on hills after tuning. Might be something to check in to

 

You could call Mike at 5Star tuning, I have the same motor and it work it up nicely and he can tweak the tranny shift points and pressure, ect.

 

Thanks for the replys. Looks like I should leave it in regular mode when driving on flat stretches and return to "trailer/haul" mode in the hills/mountains. I didn't try the regular mode on the way down in fear of damaging the tranny, but from what you guys are saying this should be ok on the flat. I will talk to a local vendor about a different program for the computer.

Many thanks

 

The main reason I HATE these computer controlled auto trannys is the hunting they do pulling a load. I think Ford should offer stick shifts again for 150 buyers. I know I'd trade my 2010 in for one.

As far as taking the tranny out of "Tow Haul" mode while driving, I've tried that and mine will NOT switch in or out of the mode it's in until I come to almost a complete stop first. Now I suppose that's broke too?

BRING BACK STICK SHIFT!

 

I wouldn't waste your time or money going to a dealer. Sure, there are plenty of proven and not so proven mods which could benefit you. Much of the advice you received is spot on. Your truck sounds like it's doing what it's supposed to do. Shutting the tow/haul mode off (even while pulling) isn't going to hurt anything. For your engine and load, cruise control only when it is perfectly flat. Don't feel it absolutely necessary to drive the same speed limits as everyone else coming home. Slow and easy. Normal mode for flat, lazy hilled stretches. Depress the tow/haul button approaching a good grade, and leave it on down the hill til you think you're almost decelerating, then flick it off. At stoplights, or any time you're accelerating away, flick tow/haul mode on. Once up to speed, flick it off. It really is a bit of trial and error, until you get comfortable. There's also nothing wrong with keeping it in tow/haul mode the whole drive. I just feel my truck runs better using it as described above. Everyone has their opinion to how it should all work. And in most cases, everyone can be right. Engine choices, rear gearing, loads pulled, and payload carried all have impact on how it all works.

BTW, I grew up in 'the Landing'.

 

Thanks again everyone. What a great forum. Very nice to hear from a fellow Holland Landinger "BLU4TJW".

OK my plan is to do nothing at this time. When I head home I will try regular mode on the flat and see how it works out. Obviously new gearing would help/solve the issue, but that is a very expensive fix for an annoying problem.

Just a note I picked up on this site. ST trailer tires have a max speed rating of 65 MPH.

 

Hmm! I never even considered this, but will keep it in mind on my way home.

Thanks.
