Ford Super Duty (1999-2016) :: Downshifts When Hit Brakes In Tow Haul Mode On Steep Downhill
May 16, 2016
New 2016 - 6.7 automatic with exhaust brake:
In tow haul mode is the exhaust brake automatically activated or do you still have to turn on by button? Getting mixed answers, and seems to me that it does not activate unless you push the button which is seems to be what the literature is saying.
On steep downhill pulling heavy trailer, in tow haul mode every time you hit the brake it downshifts, and isn't long before it will over rev, unless you kick it out of tow haul mode. is there a way to hold it in a gear in tow haul mode? Or should I shift into manual mode at the top of the hill then use the +/- buttons.

This maybe a dumb question. But when do you use this feature? How many pounds should I start using the tow mode? I dont haul much. I just haul a 4place trailer with 4wheelers. And in the bed another 4 wheeler or camp gear. All the 4wheelers weigh over 650lbs wet and the trailer not too sure but its steel.
My truck doesnt have a hard time hauling, it shifts fine. Feels like its not even hauling anything. I did use to tow mode once but it seem it just keeps the rpm higher and I felt that the highter rpm was not needed when I was hauling.

I have a 2009 F350 and use it almost exclusively for towing. Every time I stop to fill up or eat or whatever I have to push the tow haul button again when I start the truck- no big deal really just annoying at times because I don't always remember to turn it back on. Is there a way to have it turn on with the button and not turn off until I push it again (even after the trucks been turned off)? I suppose while we're on the subject same with the heated seats?

I have just bought a 2004 F-250 SuperDuty 6.0 Diesel with 98k miles from a Ford dealer (no warantee)...
Just after I drove it home I noticed the Tow/Haul mode switch was not working - no dashboard light and no transmission downshifting.
The dealer took the truck back in and kept it for 2 days, it came back working, they claimed to have replaced the gear shift lever. 500 miles later and the Tow Haul has failed again.

I have a 2006 f-250 super duty with a 6.0 and auto trans. I was pulling a trailer with about 5k of vehicle on the trailer.
Problem : after a long trip on good roads, I had to pull a steep hill. climbing the hill i did not shift into tow mode and all of a sudden my engine raced up to about 3k rpms and seemed to either shift to low or ( maybe ?) the Governor may engaged ?
Anyway I made it to the top of the grade and it seemed to be fine from there.
Question Is the trans broken, or did the computer maybe try to protect the trans ? It seems to work fine still?

My 05 SD started to flash tow haul mode and check gauges message came on while I was towing my car hauler trans temp gauge quit working then check engine light came on too truck runs fine disconnected batteries then re connect them ( trailer now disconnected) problem solved for about 3 mi of driving then it came back w/o trailer I'm thinking rusty trailer ball on hitch caused this maybe not a good ground for trailer tow computer? What kind of scanner etc do I need to possibly clear this problem out? I am the original owner never seen this happen with this or any other trailer I've towed.

One of our trucks, 2004 F350 Powerstroke, my company truck, recently the last snow even we had, my tow haul mode would pop on and off almost evertime I shifted from drive to reverse while plowing. I didn't want it on, it just kept poping on and off. Thought maybe the button was stuck, but it moved like normal. My other thought was there is a loose connection in the shifter or column causing it to go on and off.

Two/haul fails to engage and does not light up dash indicator light from time to time. After 4 or 5 tries it usually will engage normally. No codes.

I just noticed that on the highway sometimes (3 times) the tow/haul light is lit. I press the button and it will not turn off and when I get off of the highway I can tell the trans is shifting through the tow/haul strategy. Once I shut the engine off and restart it the light goes off and it drives normal. When it is driving normal I can turn the tow/haul off and on with no problems but noticed the light coming on it's own recently.

While driving in 2H, my tow/haul feature comes on (light on gear shift glows)

All of a sudden my T/H doesn't work while I am driving. If I stop and put in park, I can press the button and it will go into T/H. Once I am driving, it won't go out of T/H, and visa-versa. Is this a sensor issue or something more serious? The tranny works fine in either situation, downshifts correctly.

I have a 99 F350 V10 that has started with shift issues. While driving in drive it will down shift to first for no apparent reason and not shift back up. If I drop the shifter to second it will go back into second from first. I can then shift back to drive and it goes back to drive. It will last a few minutes and then down shift again. It's a dually dumper if it matters..

This morning, the tow/haul light came on, tranny temp gauge wouldn't read (stayed below zero), "check gauges" warning came up on the panel, and "check engine" light came on. Truck ran fine/shifted fine, always has.

I have a 2005, f350 6.0. I am new to owning a diesel and have a lot to learn. My truck runs excellent and has no issues,until I push the tow haul button in! It starts bucking at 2,000rpm and my rpm's shoot down to a low rpm and jump back up to a higher rpm. It's like the truck wants to shift but the tow haul is enabling it so it falls on its face i have never heard a truck or seen a truck act like this, but everyone says you don't want to pull with an automatic without the tow haul. I have just been leaving the tow haul off and the ruck pulls just fine.

So coming home yesterday from our camping trip the tow/haul light started to flash. this was about 40 miles into the trip. So we pulled over, the tranny fluid looked low, so I added a little more. The light stopped flashing, but maybe another 20 miles it started again, we pulled over and it stopped. We got to a rest stop and after about 20 minutes, I called Good Sams Roadside, there tech said to take it out of tow/haul mode and so we left the rest stop and it was good for just about 40 miles.
We hit another rest stop, at this point we were about 80 miles from home. I did not feel any difference in the truck shifting or if it was acting different. The light flashed again, sometimes going off, then coming back on. We hit two more rest stops, letting the truck rest. We left the last rest stop, we were already halfway up a big hill on the Mass Pike and after 5 miles the light came on, but then after a few miles it stop and from that point to my house ( which was just over 50 miles) it never came back on.
The truck is a 2006 F250 gas that just hit 100,000 miles. New motor put in over the winter and a few years back had the cam phasers and some work done on it. Could this be some sensors, etc that is starting to go and needs to be replaced?

My 1999 F250 has a pretty good shimmy at around 65 to 75 but only when going down hill. It seems to intensify on the steeper grades. I am thinking possibly not enough caster and when going down hill the geometry changes enough to start the shimmy. It will subside as soon as it levels out. Up hill or level it drives fine and is smooth and steers well. It has the solid front 4wd axle....

I have a tow haul problem with my 2008 F350 6.4L. It will not go into tow haul unless I tilt steering wheel up all the way and than slam it down and than it will engage. Than when I want to take it out, I have to shut off truck. Any wiring diagram and info on how to get at the wiring. Do I have to disarm Air Bag and pull Steering wheel?

Well I went about 20mi to pickup a door for my inlaws. Get about a mile from home and my tow haul light is flashing. Truck starts shifting strange then I smell it trans fluid. If course I get stopped by a red light shut it down. Started and had to rev to get it to move now four houses away from home coast into the drive shut it off and trans fluid is covering the entire bottom of my truck. Even the rear tires inside are covered. I had the wife crank it and I blew a trans line near the ext. trans oil filter. What are the chances that I did not toast my trans? No prior shifting or slipping problems before this mishap.

Experiencing a melt down with one of my trucks. One of our trucks is an 06 F250 SD with 80k on a 5.4L and the other day the tow/haul light started to flash. I took it to a buddy's repair shop (who is an experienced Ford tech and tranny guy) any way, it shifted fine until about the last 1/2 mile before I got to his shop, then it started shifting in and out of different gears. He found solenoid "A" pressure solenoid failure and one other solenoid failure, he replaced all 7 solenoids and also found the pigtail from the transmission to the wire harness bad as well and replaced that. I pick it up and get about a mile down the road and the light starts to flash again so I took it back, he ran his scanner and now found something with the coast clutch and through all his testing it told him the coast clutch needs replaced. He removed the trans. and tore it all down and found nothing wrong with anything, in fact he said everything looked in great shape and thinks the pcm failed.

I have a 2006 6.0. It's hard to put into to drive and for you to get it moving you have to just about floor it. The tow haul light is flashing but my bullydog won't pull the codes. It stops moving after like 30 to 40 ft after you got it moving and acts like it's in natural. If you turn it off and back on it sometimes will move another 30 to 40 ft sometimes. It also sometimes if you put it in reverse won't let you give it gas. Like you can push the pedal but the rpms won't climb for this reason I'm thinking something to with a solenoid or fuse or something along those lines and also because if you restart it will move again. I don't know much about transmission. I'm taking it to a shop tomorrow for them to try and read the codes. If they say the transmission is toast i already located another one 2 hours away to swap in which I'll do myself to avoid the high cost of the shop which also I'll look to yall for guidance. I drained some of the transmission fluid and didn't see any metal flakes. Should I pull the pan as well and look if nothing is coming out in the trans fluid ?
