Ford Super Duty (1999-2016) :: Transmission Not Shifting Into Tow Mode When Pulling To A Steep Hill
Oct 23, 2014
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?

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.

I have a 2008 F350 with a 6.4 Powerstroke diesel engine that just experienced total engine failure. It has around 65K miles.
There is a heavy burn star pattern on all 8 pistons, a few pistons are cracked, a few cylinder walls are scored, glow plugs are melted, both heads are cracked with multiple stress fractures in each head.
About 1 month previously, the transmission would not work in tow mode and caused the engine to go into limp home mode. The dealership just replaced the entire tranny as a warranty item. About 1 week before the engine failure, I put in a 5.25 oz bottle of Lucas injector cleaner with a full tank of gas.
The Ford dealership is saying that the star pattern on all 8 pistons is due to high pressure fuel overspray and is evidence that I had a tuner on this engine and that the warranty is invalid. I did not have a tuner. What might have caused this engine failure?
Also, they only ripped down the top half of the motor, not the bottom half. I heard this might have been caused by a cracked crank shaft, but Ford refuses to investigate this possibility.

I own a 2006 B6 and I'm just ticking down the list of common repairs... The last series started with boost lost anytime the car was pulling a steep hill or high acceleration. Eventually I lost boost altogether. I replaced the PCV valve and got back a little power but still no boost. This last weekend I replaced the DV valve. The old one was visually shot. The new one is the latest revision of that valve. Now, the boost will kick in, and cut out, kick in, cut out, in a rapid cycle during any acceleration. I double checked that it was installed and tightened (stripped the bolt heads) and reseated the electrical connection. I'm still getting the rough on/off of the turbo. If I slowly increase the acceleration it will act better, but that isn't a sure thing. I love the car, but I'm about to reach the point of pushing it off a cliff.

I have a 2012 F-250 ccsb lariat and the shift from 3 to 4 seems to be a bit prolonged as if the converter is slipping and wont go ahead and push it into 4 gear. Also it will want to downshift from 3 to 1 and feels like the car behind nailed you. I have read that the early 2011 had some of this problem and the dealer reflashed the tcm and it did not do much good but as mine being a 2012 mine should have been flashed with the lastest tcm flash from the get go?? Egr fell off and am running Kory Willis tunes through ez lynk so the stealership is probably out of the question. I have also read that changing a couple solenoids( dont remember which ones) will fix the problem.

Recently I have had an issue with my auto which was just rebuilt. About 500 kays after i picked it up it shifts dangerously hard and immediately into all gears at around 20-40 mph, converter also locks immediately. The speed sensor in the box was replaced with the rebuild but I'm having it replaced again this thursday just in case.
Just for the record I cooked it on the beach a while back, the speed sensor was replaced with the rebuild as it was doing the above, the od light also flashes when this occurs, before and after the rebuild.
Prior to cooking it never had an issue.
What could be causing it? I'm starting to worry it cant be fixed, have done a google and tried a couple of things mentioned. Code says wiring issue associated with speed sensor in box.

I have a 2002 ford f250 with the 7.3l diesel. I recently installed a ts performance chip. On my pcm. And after i first tried all the different stages I didn't like how my transmission was shifting hard. So I contacted the manufacturer and he told me they could reprogram the chip for smoother shifting. So I removed the pcm and removed the chip. But when I went to reinstall the pcm I bent one of the pins on the pcm some how.
So I took it back out and straightened the pin with pliers . i reinstalled it back in the truck. Only to find when I reattached the battery cable I have no power to anything ignition ,horn, lights,Cigarette lighter etc. So my question is if the pcm is bad, or not contacting properly due to the pin being messed up. would that have anything to do with the lights and horn and all that? I suspect its the gem bsm or Vsm. Whichever one my truck has. But really not sure because everything worked fine just 20 min b4.

I have a 2011 F-350 6.2L that has extremely hard shifts from 3 to 4 going up and 2 to 1 going down. Sometimes on downshifts it feels like something has ran into the back of the truck. I had the computer updated when the truck had approximately 40,000 miles on it and he assisted a little bit. The truck now has 140,000 miles and it is back to shifting horribly. I put it in the shop at the dealer on 30 December 2013. The dealer says that the problem is that the shift solenoids need to be replaced but that they are not available. The truck is still sitting at the dealer and I am being told that the parts should be available mid February.

I have a 2000 F-550 w/7.3 and a 6 speed ZF transmission. My problem is that when you go to shift into any gear inc. reverse the transmission stays in 5th gear. I pulled the shifter and tried to do it from top of transmission it still stays in 5th. Any thoughts that I could possibly check?

My buddy's 2001 7.3L F350 has had 3 transmissions. Rebuilt and used. Once the new trans is in he goes like 15 miles and then is starts shifting hard and grinding gears. What this could be?

I have an E-350 with auto trans and 460 engine. I am away from home and hope to make it back where I have tools to do the major work. I drove up a very steep hill and the trans fluid leaked at the steep part, but only when pointed uphill. I did it a 2nd time and it only leaked at the steep part (I was not aware of this the first time or I would not have done it again). Fluid was dripping out pretty good at the bell of trans. No leaks when in drive or R when engine running and level.
I added fluid and tried to back uphill to get van out of this place and it worked fine for a min, but now just rolls downhill. My question is can I just add fluid and get home? What the leak is? How long I can drive it, or if it will leak too much? When I get home (150 miles) I can do any repair needed, Im just trying to get home now.
I know we will be guessing a lot. Van is a 1995 Ford Cube Van, formerly a Ryder moving van. E-350 with the 460 engine, and 3 speed OD trans. I don't know any more detail on the trans. It should be heavy duty given it was a moving van. Van is probably 10-12,000lbs.

I'm working on my brothers 99 f250 super duty 2wd. The truck pulls to the right. Here's the list of things I've changed and checked
1. Gear box
2. Tie rods
3. Ball joints (aligned)
4. New bearings and seals
5. Brake rotors and calipers. Front and rear.
6. Rotated tires front to back
7. Rotated tires in cris cross pattern
8. 4 new tires (factory size tires)
9. Rebalanced tires
10. Aligned for a third time.
And the truck still pulls right. What is causing this!

Just had my tires rotated (which I do ever 5,000 miles) and an alignment done. Alignment appears to be in spec, but she is pulling/drifting to the right. Dealer suggested I get the tires cross-rotated, which I had done yesterday, but she is still drifting/pulling... not sure the difference. Pretty sure I have to get it back to the dealer to address, but just looking for other possible causes to potentially prevent that trip.

My current 08 duty was bought with what I believe to be a procomp 6" lift modified to an 8" lift. The 100 mile drive home after buying the truck showed a tiny "hop" in the rear. I ditched the 37s for some new 35s. Still a tiny hop, mostly noticeable while under a load like climbing a hill. I pulled the rear driveshaft and had it fully rebuilt with a new carrier bearing as well. Still gots the hop? The truck has a carrier bearing drop bracket but I think it may be insufficient for the lift.
The rear driveshaft still has a slight bend in the middle of where the two driveshaft pieces connect. Are the 2 piece driveshafts on your 8" lifted trucks sitting straight with each other or do they have this bend as well?? I am thinking if I get a bigger drop bracket it may cure this slight hop I have? Lots of lifted trucks where I live but they are dam near all shortbox with 1 piece rear shafts so I haven't been able to find one to compare. By the way, my truck also has pro comp rear traction bars..

1999 f250 5.4L... Its done this 3 or 4 times now. Driving and it starts pulling to the right pretty bad, almost like if the front passenger tire was messed up or something. Today it did it, after I let it sit for a few min, then drove back to the house, it drove straight. Also, when it pulls to the right, its very sluggish, as if I'm pulling a very heavy load. From a stop, it doesn't even go until I hit the gas, and at that its very sluggish, sorts feels like if you drive off and forget the ebrake is on.
Also I've noticed some burning on the passenger side which I've read is probably the head gasket. I can see the oil dripping on the exhaust, causing the smoke. Also, my CEL just came on, with code P0401 "powertrain exhaust gas recirculation flow insufficient detected". Recently changed the plugs because it was running and idling a little rough.
At this point in wondering if the pulling issue could be something with the brakes, when I'm driving, it sounds like something is rubbing, I haven't looked at the brakes yet but I'm likely going to do new pads and rotors all around soon anyways.

My Superduty has been pulling to the left when I hit the brakes for a few months now. In the past it's done it, like within a year or two after buying it brand-new off the lot, but that was because one brake pad had rusted itself to the bracket and was not doing a darn thing. Once or twice more, it was a stuck caliper pin, which was quite obvious when working on it.
Last year, around August, I replaced the rotors and pads with Advanced Auto parts stuff. Rotors are still great, pads look brand-new, and it wasn't pulling up until the past month or two.
But this most recent pulling has been a problem that I can't find. It's not the pins, it's not the pads, and now I find out, it wasn't the calipers
This past weekend I went so far as to replace the calipers with Napa rebuilt "semi-loaded" calipers (all hardware and pins and bracket, except for the pads) and pressure-bleed the entire system. The old fluid was green, not black, but now that it's been bled, the pedal is a bit firmer than it was.
I wasn't going to replace the calipers without checking them first, but I broke both bleed nipples off and I wasn't about to wrestle with an easy-out and try to get the darn things out. Per side, rebuilt caliper with hardware and bracket, can't go wrong. (Checking the calipers would have involved using a C-clamp to compress the caliper slightly, then backing off the C-clamp - if the pistons come back out a slight degree, they are free and the seals are still "grabby" and resilient).
While bleeding it, I saw a piece of black crud (rubber?) about 2-3mm in size come out of the left side. Didn't think much of it, figured it was just built up crud from somewhere.
Today, the first commute after doing the calipers and bleeding, it's still pulling just like it was before the calipers. However, I did notice at one point when I hit them, they pulled like they normally do, but seemed to go straight a few seconds into it. It does seem that if I keep my foot on the brake, the pulling is much less after the initial second or two, but if I stab them again, it pulls like crazy.
And by "pull" I mean the steering wheel actually moves in my hand. So with that in mind, it's actually a front-brake problem. If it was the rears, the wheel wouldn't pull like it does, and if it was something loose in the suspension, I would have found it already after checking everything, and it again, wouldn't pull the steering wheel like that.
Now, given that black piece of whatever that came out of the left side, I'm beginning to wonder... if it was rubber from the inside of the hose.
Is the right brake hose causing the pulling because it's coming apart just like the left one might be?
I've gone over and over this in my head this morning, and thought about the ABS unit possibly dumping pressure from the right because of a leaky valve (see side note below), but I would think that once the pedal stab was over, it would even out and not pull at all.
However, this thing pulls left quite a bit, even after the pedal has been held down for quite some time. Usually. Sometimes, it subsides and doesn't pull. But mostly it does no matter what I do, keep pressure on the pedal, let up and reapply, whatever.
Does this really sound like a bad hose? It's intermittent, but usually pulls like 90% of the time.
Side note: The ABS unit in my truck, and most Fords of the time (not sure about later than 2004 or so) is a Kelsey-Hayes three-channel unit like this:
Kelsey-Hayes RWAL Antilock Brakes
It's the same system found in Chevy Suburbans and light-trucks, which I have worked on before and know a bit about.
In my case, it can't be a dump valve leaking, because it would effect pedal-height and not PULL to one side like it does. The only way that could happen is if the isolation valve was closed, AND the dump valve were leaking at the same time.
I haven't, however, gotten the ABS to activate just to see if it changes anything. On my way home tonight I will see if I can find some dirt or sand and get it going

My 2012 transmission seems to slip a fair amount (much more when it's cold).
When I say slip, I mean, when I give it the gas, it will rev up sometimes, and not move or move very little, while other times it will jerk around like a wild horse. The engine will rev / jump from 2,000 rpm to 4000 back and forth, back and forth. It will do this until it shifts to a higher gear and will stop doing it after 5 - 10 minutes?
On one occasion while going up a steep hill, it starting going backwards while I was giving it the gas. It caught up to itself and started jerking forward until it caught and went forward.

On a steep hill, mine rolls back when the transmission is in high range, but it does not roll back when it's in low. On a mild incline, mine does not roll back when the transmission is in high.
VIN: '04 43xxx; latest tranny flash ("520" was the number, I think).

My F250 is displaying error messages for the hill descent/advance trac yet again. My truck was in the shop over 7 times about 6 months ago when my instrument cluster would go crazy. Every warning possible on the display, and once you killed the engine it wouldn't start until the dealer cleared the codes...once they flew in an engineer he fixed it within a couple hour timeframe, and I thought that nightmare was over.

I have a 2001 F350 with a 7.3 diesel and automatic trans. I purchased it about 100,000 miles ago. It is all stock as far as I know. The mileage on it was about 14-15 on the road and I decided to put a chip in it. I was somewhat leary of putting too much power to this old of a rig. I put a TS Performance chip in it. It seems to have more power. I am towing a 30 ft. Gulfstream Seahawk I think around 10,000 lbs. When I started up a hill it made a different noise like a screeching noise when I pushed it. When I back off a bit the noise goes away. When I put it back to stock setting the noise is not there just the normal downshift and increased RPM. Not sure how to describe the noise but sounds like a metal bearing type noise. I get the same rush of air or what ever that sound is when it changes back to a higher gear. Is this sound normal or what might it be. It sounds normal when not pressing it.
