Ford 6.0L Power Stroke Diesel :: 2006 - Stumble Always Worst On Final Drive Gear
May 19, 2011
First... Items I have replaced:
- New EGR valve
- New sensor
- New Fuel filters
- New Oil filter
Problem:
While driving I have a stumble along with a small amount of black smoke at this time ( was white/bluish smoke ) previous. I have dis-connected the batteries to force the computer to relearn the EGR valve. The turbo spools up .. getting about 20 psi @ hard throttle and then about 5 psi after it goes into the final drive gear. Speaking of which ... the stumble is always worst on the final drive gear...

I have a 2006 F-250 4x4 with no cat, and no egr but the valve is still connected. It has about 146,000 miles. Just recently when warm, it has a slight miss every once and a while when stopped and in gear. Just a slight drop in RPM then recovery. Its mainly used on the highway and 99% of the time I set the cruise and its smooth as silk. Every once and a while I feel it stumble once or twice, recover and it is fine for the next 80 miles with no issue. It started as once every few trips but now It seems to be happening at least once every other. I use Motorcraft filters (maybe 6K on the fuel filters) and rotella oil. My scangaugeII shows no codes and no Injector pressure issue (1200-1400 at 75 mph depending on grade) and the FICM voltage stays between 48.5v and 49.0V. What should I check?

So I have a 06 350 and I'm getting clunking from drive to reverse and now with drive too, I know my rear diff is on it's last days but I am wondering if that could cause the clunking and now my truck around 90km shakes likes crazy and same thing wana know if that's the diff. And if I was to fix diff myself would it not just be easier for me to just swap axles if I wanted to be cheap??

I just bought a 2004 F350 6.0 cclb 6 speed with 260k on it. The previous owner seemed to have taken good care of the truck. It is basically stock with the exception of the blue spring mod, and a sinister diesel coolant filter. Anyways, I brought the truck home and it ran great. Now I have an issue that needs to be addressed.
The issue: I am experiencing a intermittent loss of power, stall, or stumble when engine is cold. After sitting all night the truck will start fine and idle fine. But when I try to accelerate and bring engine RPM up the engine will stumble and lose all throttle response, when this happens the WTS and WIF light flash. Sometimes it just stumbles, sometimes the truck will actually die and then restart. The issue seems to go away after the engine has reached operating temp.
I did some research on the issue and it seems there is actually a TSB out from ford for this issue. It explains that some 2003-2004 6.0's might have wiring harness chaffing issues. This is what the issue I am having seems like to me (shorting harness). I looked up codes on the truck and there is an active code (#8 glow plug circuit fault). I did a short visual inspection of harness and didn't see anything out of the ordinary. But i wonder if it would be worth changing both sides of the glow plug harness?

I have a 2004 f350 6.0 it has 73000 miles on it. I've had the truck for about a month and its developed a slight stumble, hesitation. It does it during idle and acceleration, if I give it more throttle it smooths out. The cel is not on and there are no stored codes.It did this a few days after i bought it,i noticed the map sensor was broke in half so i replaced that and it smoothed out.But it came back. Exhaust is clean no white or black smoke at all.

So from what I have gathered online, it is an injector(s) issue. I've only had it happen to me twice at that speed but when I came to a stop afterward, my truck was barely idling.
I'm not sure if my sct programmer is able to show injector codes but it will show gp codes. I guess my question is are failing injectors that intermittent typically? Also, much luck with Rev X clearing that issue up?

I've mentioned in earlier posts that my speedometer has been swinging around wildly off and on, and that on two occasions this has been coupled with a momentary engine stumble. This morning on the way to work it was doing it again but this time the engine stumble happened several times as well. I plan to check the speed sensor, but I wonder how this is also causing the engine stumble?

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?

My mechanic just informed me that because of my extreme drop, the drive shafts are at an angle that is stressing the final drive bearing on the transmission. I am leaking very small amount of fluid, he said it might not be a big deal.

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.

Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.
One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).
I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.
These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.
One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.
Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.
Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.
When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.
Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.

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.

Today I was driving my 04 f350 6.0 I got to a red light when it turned green I hit the accelerator and it would not go it would only go about 10 so I limped to a parking lot and it shut down, it will crank and it sometimes Will start but only rev up to a grand then put in drive and it dies I had someone run me out a new pre programmed FICM and I replaced it right there and still will crank but won't run so I had it towed to a ford dealer and dropped my key in the drop box, what it may be?

I have a 2004 6.0 with the 5L110 transfer and torqueshift transmission. While test driving after installing everything, I didn't get 7 ft down the road and the tires locked up and she came to a dead stop. Now I only have reverse but I can still feel the tranny engaging into drive but will not move.

I replaced all my shock and the last one front passenger side gave me fits. The lower mounting bolt stripped and I am unable to secure the shock. My question is..is it safe to drive around without the front shock to get over to the parts house? I plan to use back roads and low speeds. 20 mile round trip.

If the truck is cold when i put it in drive it engages fine. Drive to the store, start it up again after its warm, I then need to rev to 800 rpm to get it to engage. Once drive is engaged one time i can go from park to drive, rev to drive doesn't matter it works correct every time. Rebuilt the transmission with suncoast kit. New precision industries billet torque converter. New trans pump, new valve body, replaced all pistons and seal rings. Replaced all the solenoids except lo rev and overdrive. Will change those in the next couple days. Side note transmission had this exact issue before i rebuilt it. Exhaust back pressure reads 55 to 60 psi at idle. I replaced sensor, cleaned pipe, and checked the wires for cuts. Previous owner had a smoke switch wired up at some point but he removed it before i bought it. Truck is tuned by innovative, sxt livewire... does the same thing with stock tune.

On Saturday I drove my truck 450 miles, all of it towing, in hilly New England. The turbo boost gauge was operating at 20psi or higher for many of the hills, and the 13mpg average was indicative of how hard the truck was working (normally empty I will get 20+). The next day, I drove it about 3 miles and it started a regen. Why? Wouldn't it have been passively regenerating for most of those miles? A steady 75mph for hours at a time?

I have a 2015 Ford F-450 6.7L Diesel with a 12 foot flatbed on it that I use for my power washing business. The air conditioner sometimes won't work when I first drive it in the morning. After I make a few stops and turn the engine on/off a few times it will all of the sudden start working again.
This happens about 2 or 3 times a month and I don't have time to have it sit at Ford so they can duplicate the problem. It's going in for it's 60,000 mile service in the morning anyways so I'll still have the dealer look at it. What might be causing this?

Me and the wife just now noticed this issue after about a week of owning this 6.0 f350 auto 4x4. Leaf spring front and rear. Long bed. Listing all this stuff because not sure if it matters.
Around 50mph if we drive normally about 1500rpm the truck seems to jerk a little as we climb in speed. If we get the truck into the 2000rpm range it goes away.
Not sure if it's suspension, transmission or engine. Any clue what it could be. ???

I have a new issue that started last Friday. When I put the truck in gear and let it begin to pull itself, drive or reverse, it has a strange jerking or slipping deal. It doesn't happen every time but when it does you can feel it in the drivetrain. I took it to the shop that did the motor work and they ran a diagnosis(while I watched) on the motor and its turns up nothing. It runs perfect, shifts like it always has, but just has this jerking/slipping thing when I let off the brake and it starts to pull itself.
If I go from brake to throttle its fine. I had the rearend diff worked on to fix the leaky ring and pinion seal and the differential cover sealed at the dealer last month. I searched and don't see anything like what I am experiencing. Could my tranny be giving it up now? It has never been overworked and never overheated. I had the full fluid service done at about 70k and now it has about 130k on it.

I've pulled the fuel lines and disconnected all the electric plugs. I don't seem to be able to remove the unit as the 4x4 drive shaft is in preventing me from full removal. Is this possible? Do I have to remove the drive shaft? Very frustrating as this should have been a 15 minute or less job. A video would be useful, but all my searches show only two wheel drive removal.
