Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sneeze Like Hesitation Just Before Downshifts To Passing Gear
Nov 4, 2016
I have a 04, f-250, with a 6.0 liter engine. I have had the Cat removed and in the last couple months it has developed a sneeze like hesitation just before it down shifts to Passing gear, If I push my foot into the fuel it jumps right down thru the sneezing into passing gear. I have changed fuel filter and grade A cleaned my EGR valve. the only Codes it throws is P0403 and P0405.

On cruise control, engine went dead immediately after passing gear kicked in. After 2 days on the side of the road got a pull to the house. Then after having a charger on it over night the electric seems to be messed up. Switched on, the dash lights light full strength for a fraction of a second before appearing as thought the battery is real low. Also the doorlocks act crazy. I think maybe I blew out the BB on the high oil pressure pump.

2013 CCLB, 33,500 miles, stock emissions
While towing a 9000 pound trailer at interstate speeds (75 to 80 in Wyoming), when pulling a hill, the truck downshifts to 4th gear, boost is about 18psi, eng and transmission temps in the 230F range, EGTs around 500C or 935F. RPM increases normally to 3000 then the turbo gets very loud and boost drops to about 10psi. The truck shifts to 5th gear, noise decreases but is still present, shifts to 6th and noise goes to normal after a couple seconds and boost builds normally.
This just started today. I have about 8000 miles towing this trailer and never had this before. I have about 350 miles until I'm home so I'm headed back out. Will play around with manual mode and see what it does. I also took a video of the gauges while this happens. Audio is difficult to discern. I will try to get better audio and post when I get home.

Finally registered on this site after hearing good things from others who are currently on here. Been a 6.0 PSD owner since buying the truck since new in 2003-F250 CCSB. I have done regular maintenance on it and have had a good run until recently. Everything is stock on the motor and currently has 229 000 miles.
I will describe my current problem: I have borrowed my brother's tablet and have the following numbers from the Torque pro app. While trying to accelerate it now has a hesitation and seems to not have the power.
At idle: 630 psi HPOP, 24 % IPR, 47 volts FICM, ICP volts .1
Trying to accelerate on at highway speeds: 1230 psi HPOP, 83% IPR, 47 volts FICM, ICP volts 2.6
Also, sometimes when starting the truck it seems to rev extra high for a split second. My brother says I may have a high pressure leak on the system. What I should check first?

When passing or going up small inclines on freeway, my F250 seems to make the shift to the passing gear but then almost a complete loss of power. Jerks around for a few seconds and finally provides enough power to at least get back to the original speed. (It feels kind of like the lurching, etc. I used to get when those stinking GM diesel injectors would act up in the 1990's.)
It also stays in first/second as I punch it while entering the freeway and doesn't want to make the shift. I can put it in neutral and race the engine, so I don't think it is an engine problem, unless the transmission is electronically controlled. I have a lot of computer dashboard gauge resets after falling to zero and sometimes have to set and release the parking brake to get the auto door locks and windows to work. (That started after a car break in where the door electronics were apparently pinched, but that was a couple of years ago.)
Does it sound like the transmission or electronics? In the old days replacing an automatic transmission filter seemed to fix a lot of transmission issues. Not an option now, but would I expect to see any results doing a transmission flush and fluid change? It's probably been about 60000 since I had that done. (157000 now).

Cooler weather has arrived and my 2000 f250 won't start. Wait to start light is coming on, no power passing through the two relays on top of the engine. Are both of these for glowplugs? My 97 only had one. How do I diagnose relays on this truck? If you cross out the two relays truck fires right off so I know the glowplugs themselves are good.

Looking at an EGR delete in the very near future. Any problems passing emissions with a full delete?

When the truck shifts into 5th gear i instantly feel a constant vibration and noise until it shifts to 6th gear. This happens nearly every time while driving at 40mph. Rpm range 1200 - 2000. I bought the truck new on June 30th and noticed the problem on my way to work on Monday July 2nd. Took it to the dealer on July 5th and the tech said it was the torque converter slipping. I drove it home because they didn't have time to work on it. Took it back on July 12th and the dealer has had it since (currently 30 days) They originally told me it was not the engine or transmission and it was an exhaust problem. Last week they said it was the motor mounts and said they would be done.

I have a 4r100 on in a 99 7.3 4x4. The shifting problem I have appears to be intermittant. it seems loose after warm up especially at the 4th shift overdrive and passing gear. possibly due to low presures ? sometimes (lately more often than not) hunts back and forth between 4th and o.d when passing or hill climbing. Under normal driving it shifts somewhat firm with 4th being an exeption.I have changed my crank position sensor filters and fluids which had turned dark and improved slightly. When I pulled the pan and replaced the filter the pan was spotless. No residue or signs of plates or debris. There is about 100,000 miles on the tranny and 350,000 on the truck. Questions: Is there a tcm for this transmission and if so could it cause these problems? I'm considering a purchase of an unlocked 1705 superchip to change the shifting but unsure if this will work for my issues...

Why I am smelling coolant? I have a 2004 6.0 SD.It generally happens when accelerating up to freeway speeds or passing cars, Medium to hard acceleration and the smell is strong and will go away after a few min. The obvious thing is to check for a leak but I haven’t seen any.

I have searched and have found a few threads on various transmission shifting issues. However nothing really pertaining to 13+ trucks that is only happening under certain conditions. It seems earlier trucks with problems were experiencing it all the time, not intermittent.
Here's what I got.... This only happens when:
- temp is 20 degrees or colder
- Truck has been sitting and is cold
- Trans temp under 70-80 degrees
- Only happens on the 3 to 2 DOWNshift when cold
The first few downshifts from 3 to 2 have a slight clunk/bump to them...just enough to feel it. After the first few initial downshifts from 3 to 2, it will not do it then, shifts fine and smooth. After a minutes of driving it, it will not do it until the next time it meets the list of items above. If I skip this gear manually until it has warmed up, it will not do it when returning to it.
-All other gears both up and down shifting feel good just the 3 to 2 when it does happen.
Once the transmission is warm or the temp is warmer outside the problem is non-existent and transmission shifts great in all gears and is smooth as butter!

2005 F250 4X4 6.0 .. Why my truck just stopped going when put in gear and the TOW/HAUL light just kept coming on, without pushing it 2 days prior? Now it will not go anywhere, starts great, gas pedal works because RPM's go up when pushing! Just will not go when put in drive or reverse! What else I can do? I replaced cylinoid B in the transmission, speed sensor, and brake switch.

My truck just started to have issues with the gear shift. The gear shift seems very loose now and it is having trouble getting back into the park position. Is this a larger transmission issue, or is possibly a failing part on the actual shift mechanism?

I recently bought a 2005 F250 4x4 automatic trans with 177,000 miles. In the last 300 or so miles it has developed a whine from under the truck like gears not meshing. It is constant and only the speed of the truck seems to affect the volume of it. It is loudest, considerable louder, on deceleration. Different gears have no effect, 4x4 high or low has no effect, even slipping it into neutral while its rolling has no effect. I have seen various websites about bad wheel bearings, transfer cases, and rear end gears causing this type of noise. There is no vibrations, slipping, shuttering, at anything else unusual. Except for noise it drives ad rides completely normal.

I currently have a 2006 F-250 6.0 with 187,XXX.
My problem that i am having is that the transmission recently within a couple weeks started acting weird about the same time 3 of my fuel injectors started failing. When i start up the truck and put it into drive it takes about 3-5 seconds to shift. Once it's in drive it runs pretty well but it will start shifting out of normal when i go to accelerate. Also when i go to slow down sometime the transmission shifts hard to a lower gear. I also have a video of the sound that it had started to make since its hard to describe.
Here are attached videos and photos. I want to hopefully fix the problems myself so i can learn more about my truck. I am going to handle the fuel injectors here soon since 2 are failing and ones about to these have been causing the truck to shudder at around 47-53 mph but after that its fine.
The transmission is stocked and never been altered, i do admit for 3-4 years I have changed the fluids or filters.
The truck is bullet proofed, sct tuner, upgraded turbo from stock, 4" exhaust, head studs and new everything when the engine was rebuilt and bulletproofed.
I plan on going to ford tmw to have them figure out the problem and hopefully its just solenoids so i can fix it myself. I have a link posted also where you can hear the noise it has been making when in R P and when shifting going down the road and it is a automatic.

When I "step on it" on the freeway or even a moderately inclined freeway ramp, it bogs down and actually takes a few moments to cover. Sometimes will leave me crawling at about 20mph for a few minutes. Engine revs just fine in neutral. If I very slowly build up speed I can cruise at 75mph, but forget passing. Also, this came along at the same time a severe shaking/shuddering spell started. Not always, but often it is shaking the entire body and certainly through the steering wheel. Was so bad the first time I stopped to see if I had a flat. Usually lasts until I slow way down and ease my speed back up. Had the front end steering structure replaced about two years ago, so I don't think it is that. What is the cause of the bog down and could the shaking be related? This truck sits for 2-3 weeks at a time and then I drive for about 50 miles and park it again. Can Michigan gasoline go bad that quickly?

2015 F250 with 6r140 Transmission. I have 13 K miles on my truck. While pulling my Travel trailer up a hill the transmission kicks down thru the gears, which is fine, but as I crest the hill and in 2nd gear, the engine begins to rev up and the speed increases, the transmission will not automatically go into 3rd gear. I have tried to let up on the gas pedal, but it remains stuck in 2nd gear. I have to shift to manual and then put it in 3rd gear. Then it shifts up as it should. I have tried with the transmission in "TOW' and not in "TOW". I have even tried it in "Cruise Control". Ford dealership ran tests but could find no problem. However it was road tested without the trailer.

I have a 2004 F250. Owned it for a little less than 4 miles (186k on the odometer) .. The other day making a routine run and the radio goes out. Stopped to check it out and found I had no power windows either.
Made it home, checked the fuse on the radio and its good and the the power window fuse is also good. Put a meter on the terminals and have no voltage going to them. What I need to look at???

I have a 2004 F250 6.0 DuperDuty with about 170,000 miles on it, so far no major break-downs, just a starter and a blinker relay, but now I have a problem.
When I start now, the truck starts fine and it sounds fine, but it has almost no power even if I floor the gas peddle, there is a delay of like 2-3 seconds and then responds slowly, like some tractor. Eventually it starts to move slowly, and after it warms up (after a few minutes), the gas peddle responds more normal.
Also - at about 45mpg, at lower RPMs about 1250, the engine starts to shake (weird), it doesn't do it at idle about 850 RPM, or when I get it up to about 1800RPM+, but at about that 1250 RPM it does do it, luckily I driver locally for a few miles.
What could this be ? What exactly happens when I press on the gas peddle, what systems are involved and in which order?

I've got a 2004 F250, 6.0, with 150k miles. I was pulling a motorcycle trailer uphill in the mountains when suddenly I couldn't go over 10 to 15 mph. All the gauges read good but it just couldn't get any power.
Got to the top and checked over everything. Didn't see any issues. Drove it home (200 miles) the next day. It drove okay on highway but it felt like the turbo wasn't coming on. Coolant was low and EGR was gunked up but only slightly wet. From what I read, it sounds like EGR cooler is failing but would that cause the turbo not to come on or feel like that loss of power? Reading another thread, I thought it might be the fuel pickup but I dropped the tank and the sending unit looked very good.
I'm ready to throw on a bulletproof egr cooler, oil cooler and rebuild the turbo if necessary but hate to get to the end and find out none of that worked.

I have a 2004 F-250 with a 6.0 and am having a serious issue. The truck has about 240,000 miles and has been great until now. About a week ago the truck was running great and had plenty of power. I decided to wash it with my pressure washer (did not spray under the hood, however I did spray in the front wheel wells and underneath the truck). About 5 minutes after washing the truck, I took it out for a drive and noticed when I really got on the accelerator the truck would not want to try harder and motor got very quiet. Really all you could hear was the turbo whistling. Over this past week the problem has gradually gotten worse... a few days ago I had to feather the pedal in order to go up hills. If I gave it more than about 1/4 inch of accelerator, the motor once again would get quiet and the truck would start to slow down and would not want to work.
However, if I let up and only gave it a small amount of accelerator, the motor would sound normal again and it would pull up the hill. Today, I can do nothing more than idle back and forth in the driveway because the motor gets quiet and the turbo winds up if you give it even the slightest amount of accelerator. I have no idea if it's a coincidence that this happened after washing the truck, or if maybe there was a sensor that was rotted and about to die and I finished the job with the pressure washer. I already replaced the egr valve and have been running tons of Howes diesel conditioner and anti gel through it. The injectors were replaced about 50,000 miles ago so I'd hate to think it was them. The truck doesn't smoke at all either.
