1st to 2nd fine 2nd to 3rd it jumps a few times like it cant find the gear and you will see it on the video. I am confused what it could be. the truck received a new solenoid last year from ford because the tow haul light was flashing and now i have this issue. I believe it is also the reason the truck is running much slower down the 1/4.....
Video : F250 shifting problems - YouTube ....
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.

Where are the main problem areas on the ficm wiring harness truck will start and run great at times and at times it just start and misfire lope jump and buck it has to be a short I've changed the icp and crank / cam sensors some days it runs fine had issue with alternator replaced it.

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.

If I'm giving a jump:
Assume I hook positive and negative cables to the respective terminals of one of the two batteries. The alternative would be hooking positive cable to one battery and negative cable to the other battery, or does that make 24 volts? I'm also assuming if it is just the one battery, it does not matter which one you jump from?
If I'm receiving a jump:
I assume positive cable to positive post of one battery and negative cable to a good ground under the hood somewhere? Again, does it matter which battery I use? I wonder where a good ground is on this crowded diesel engine and aluminum body. Front radiator supports?
Just a quick question but is it normal for the ICP voltage (ICV) to jump around a lot at idle or while cruising or accelerating? Started watching this pid and not sure what's normal and what's not.
View 13 RepliesI'm relatively new to the 6.7 engine , I have a 2014 F-350 SRW with aprox 51,000 miles on it. Normal driving I see about 8 to 10 psi of boost even under moderate acceleration although at times it will go to about 18 psi at WOT and it does this with heavy loads. At moderate acceleration the boost will jump to 10 psi quickly but immediately stop there and sometimes as the RPM"s increase boost pressure decreases. Only issues I have had with the truck was a clogged EGR cooler.
View 2 RepliesMy 6.0 is making a weird scuffing sound when I let off the gas and after it shifts. If I drive easy it doesn't seem to happen. But if I have to accelerate fast it will make the sound in between shifts and if I let off the gas real fast it will make the sound. It only lasts for about 3 seconds or so. It sounds like its possibly in the exhaust.
View 3 RepliesLast week my 2011 KR Diesel with 85k on it stopped downshifting correctly. Basically when the transmission is cold (<150 degrees on the digital gauge for transmission fluid) it jerks everytime it shifts down from 4->3->2->1. Especially 3->2 and 2->1. I have never seen anything like this before. It's almost if you are getting reared ended when it shifts.
If I let it warm up it eventually goes away until it cools down again. I did take into the dealer and they said that a) there is definitely something wrong with the torque converter and b) I might actually need a new transmission which is anywhere between 4-7k depending on if its a reman or new.
This truck is barely broken in and I at this point have not towed a single thing with it. I had thought the transmission was covered up to 100k but it looks like it's only covered to 60 or 75k (I forgot which).
I've opened up a case with Ford but they kicked it back to the dealer. The dealer service manager has been really NICE and is definitely on my side that this SHOULD HAVE NEVER HAPPENED at this mileage. They also don't know how to fix it without pulling apart everything which is a lot of labor.
Ok so here is my problem now. I'm sure its in the tramny but not sure what else. My shift from 3-5 has always been a little hard. Yesterday on my way to work I noticed shifts 1 thru 3 were hitting hard. Once I got up to 65 mph it was okay. Then pulling into work when I shifted to reverse it didn't go into gear right away and then it would hit into gear. Later that evening on my way home from work it was shifting the same but seemed worse. Then my tow/haul light started flashing and it seemed like the torque convertor wouldn't lock in. It would just stay in 5th gear and the more throttle I gave it the rpms would go up but I would only get a little response from it. Then a few miles down the road it just completely shut off on me. It will not even try to turn over. I could also hear a noise coming from underneath the truck. Something ive never heard before. I really need to figure this out
View 14 RepliesHaving transmission problems? Everything I've read before says these transmissions are better than gm Allison's and they can handle up to 600 horse before you gotta worry about beefing them up but mines starting to act funny.
How important is the transmission tune? My truck it's tuned with the spe hot tune and trans tune. Didn't like the way it clunk bang hard shifts though so I ran factory trans tune for a while but it felt very soft like it was slipping when I got after it on the performance setting of spe hot so I went back to spe trans file.
I get a little twang sound that sounds like it's coming from the trans between 3-4 gear shifts, initially only heard it after getting on it hard in performance but it's getting worse and happens on stock power level under light acceleration now sometimes. Also I lost all gears briefly and it wouldn't shift into manual at all when I stopped to turn around the other day.
Working fine in drive but when I shifted out to reverse it had nothing in any gear and manual wouldn't light up on the display. I shut it off and restarted the engine and it came back and worked fine after that but not sure what happened there, don't think it's good though. Did using the stock transmission file with the hot engine tune or the hard clunk bang custom trans file up my trans, freak malfunction?
My friend has a 2006 F-450 and he said the Tow/Haul light blinks and the shifts are real slow. He has stopped towing now and it still drives.
I have read everything from toasted tranny to chaffed wire harness across tranny crossmember to the TFT sensor. My guess is the TFT sensor given his symptoms. If I am right the sensor is just to the rear of where the dipstick comes thru the tranny case. 1/4 turn and pull it out. Kinda like a bulb I guess.
Another question, is it necessary to replace the harness while in there as well? Is the Connection listed below the harness I am asking about? I found these parts on a thread from here:
Sensor (1): 3C3Z-7H141-AA;
Connection (1) 4C3Z-7G276-AA;
Gasket (1): 3C3Z-7C155-DA;
Fluid (10): XT-6-QSP
Purchased 2011 3 weeks ago. Due to not paying attention, put gas in diesel. Had tank dropped and drained but after reassembly, fuel gauge inop. When turn ignition switch on, get normal sweep of all dash gauges but fuel gauge does not read. 2nd tech says sender okay, must be gauge. Dealer ssays if it sweeps, it isn't the gauge. 011 F250 6.7L.....
View 7 RepliesMy 2012 diesel frequently stalls momentarily after I touch the brake. This is very annoying as I drive in heavy traffic and often have to touch the brake then accelerate to merge into freeway traffic. The dealer service department said this was a 'feature' and not a flaw. Is there any way to eliminate this issue?
View 5 RepliesI 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.
My 2006 F250 was towing my 5th wheel when it started to loose power and eventually died. Would not restart. Replaced all fuel filters to no avail. Towed to mechanic shop. Has a little over 100,000 miles on it. Waiting for mechanic to check it out.

View 9 RepliesI 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.
I had this truck for two months no problems yesterday went on a small trip about 50 miles in on ,the hwy. I start seeing some smoke and then no power turned off & on engine several times a little hard starting no power at all I put the pedal to the floor It barely moves ran into another super d. guy he said fuel filters , I turned around and crawled back home and changed fuel filters still no power. no codes "don't no where to start".
