My 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 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?
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.
View 14 Replies1st 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.....

Last 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 RepliesI 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.

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
It only happens on a very Rare occasion.
When Cold, and when I start out as I open the throttle, it suddenly sounds like there is not a piece of quieting stuff on the engine. I mean its like I can hear right into the engine itself.
I back off, It goes away then I dont hear it again for another Month or two.
Recently my brother in laws truck started making a buzzing sound while running and a much louder sound after it shuts off. Trying to track down the sound. Listen to the whole video because the end is where it gets loud.

So I have just over 14k on my 2015....... I love the truck but have had a few small issues. I had a water leak coming in from the roof that would leak through the grab handle. Nothing major dealer replaced one clearance light seal and they said the windshield needs to be re sealed.
Then I had a god awful irritating squeak in the dash..... It only does it late In the day when it's been hot. The dealer said it was a loose air bag. I have had the truck back a week and it's doing it again.
Those are little issues that will get resolved...... I hate having problems with a brand new vehicle but I understand it happens and that's what warranty is for.
I also reported a bad shake to the dealer...... The truck will shake very violently and have a very loud "diesel" sound. It's very specific at when it occurs. It has only done 4 times in the past 6 weeks including today. The odd thing is the 4 times it has done it has been the same time of day in the exact same spot on the exact same road!!!!
Basically I leave my office sit in some traffic and by the time I get to the parkway it has been35 minutes or so. Only happens in 6th at 60 which is roughly 1,400rpm a slight load due to a small incline and it shakes real bad! The typical "diesel" sound you get when under a load is very pronounced almost to a knock. It will continue to do this as you slowly increase throttle until it down shifts and then goes away. I also caught it doing it and I manually shifted to 5th and it went away.
Because of the rpm at which it happens with slight load only doing it in 6th I lean to a Trans issue and more so a converter problem. It feels like converter shutter. I just don't understand the engine sound.
I gave very descriptive info to the dealer..... Several techs drove it and could not duplicate. I just picked the truck back up last Thursday and the dash squeak is back and the shake happened yesterday and again today. So I am a bit irritated to say the least.
I really hate the fact that I know there is a problem but I also understand if a tech can't duplicate it he can't diagnose it. However today I did get a video of it with my phone so they will know I'm not making this crap up!
it's now 1,500 miles away on the side of the road.White smoke, knocking and lost power. Truck has 133,000 reman engine installed at 46,000. Is it common for hydro locking to bend a rod? He sent a video and it def sounds like a rod and degas is empty.
View 9 RepliesMy power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.
View 4 RepliesNew to the 6 liter powerstroke recently upgraded from my 7.3. Recently this odd whistle sound started and I can't quite seem to fogure out the cause. At first it only happened if I was going 70 mph and now it will do it anytime it builds more than 15lbs of boost. I tried tightening some clamps and stuff but that did nothing.
View 14 Replies2003 6.0 FX4 w/ Auto Transmission, 180,000 miles
Last transmission service - unknown (I have owed the truck for 3,000 miles). I just acquired a clunking sound when shifting from R to P or R to N. No noise from N to D or lower or back up to D. It does not grind into gear, just clunks one time. It is rather loud.
All shifting while driving is normal, no slipping, or noise. This occurs on level ground, at operating temp, and +-650 RPMs.
Fluid level is okay. No strange odor. What will be the next steps to investigate?
My truck will intermittently sound like an old 7.3 clattering away. It's done this for some time now. If I accelerate briskly it'll quiet down. When I first got it (used) it was quiet as a church mouse. It seems to normally be during the 1st 20min or so of a run. Weather and fuel doesn't seem to be a factor nor does it matter whether I have additive in the tank or not. My truck is a May '10 build 2011 with about 60k miles on it now.
Is this normal? Same 7.3 noise from the 6.7?
My 2011 is making a strange humming sound after shutdown. It seems to be related to the normal waste gate sound. I have a video....
View 12 RepliesBeen noticing it more recently. After shutting truck down I would say 15-30 seconds after some type of pump or solenoid starts running and does so for another 30 seconds or so ( from the frontnofmthentruck). What this might be? Also have noticed it just once after starting I was walking around the front of the truck and heard this buzzing sound once again.
View 6 RepliesBack again.. I just replaced the HPOP and IPR valve on my truck a few weeks ago. While the turbo was out I cleaned it and applied a small amount of anti seize on the unison ring. When installing the turbo I had moved the y-pipe a little to get the turbo in place. About a week after it was running again I started to get a squealing noise under acceleration. The noise isn't a whistle like the turbo but an actual squeal. Its a little bit louder than the turbo whistle. If I am in park and rev the engine it doesn't happen. It only happens when I accelerate and seems to be when there is boost. If I let off the gas pedal the noise stops. I don't have an issue with making boost. I did replace the turbo boot when it was apart a few weeks ago so I don't think that is the problem I checked the y-pipe clamp and down-pipe clamp and both are fine. I replaced the serpentine belt this past weekend and checked all pulleys, they were all very good with no play. Another thing, the pitch of the noise seems to change with rpm's too. What could be causing this type of noise?
View 14 RepliesI bought my 6.0L Diesel about a month ago. Recently when I turn to the left it makes a weird popping sound and gets the "death wobble" If I turn it sharply to the left it will then stop. Last night it got terribly worse and it wobbled at any speed no matter what. I put it up on jack stands and turned the wheel with both tires off the ground, and the sound still happens. I am only by myself and I tried to figure out what is wrong with recording on my phone to see if a ball joint was freezing up but couldn't see. Is there anywhere I should focus on more or less with the camera to see what the issue could be?
View 6 RepliesWell, since I replaced the MAP hose a few weeks ago the old girl has been running fine. Until yesterday. I was leaving work and she had low boost, less than 10PSI, and as I passed by a parked tractor trailer I could hear the sound of high pressure air escaping because I had my window rolled down.
So today I checked it out. I found three possible leaks spots, BUT no "smoking gun". Take a look at the pics. The damage you are seeing is on the outside of the hot side boot at the turbo and the bottom of the cold side CAC tube. The cracks don't appear to penetrate to the inside. Could these still be possible leak sites? IDK.
I'm going to order replacements anyway. Ford wants WAY to much for these parts. I checked the MAP hose and it is just like new from several weeks ago. Also, I inspected the inter-cooler as best that I can without removing it. I don't see any issues with the tanks or the tank-to-core mounting. It all looks normal. If it does fail where does it normally fail at?
