Ford 6.7L Power Stroke Diesel :: 2015 F350 Turbo - Shuddering / Shaking Between 5th And 6th Gear
Aug 3, 2015
My truck is fairly new. Its a 2015 Ford F350 with 6000 Miles. I live on the east coast in a 4 seasons climate. Its summer the average temp. is in the lower 90's. Recently, I have noticed that my truck has been shuddering and shaking between 5th & 6th gear.
It started when I was changing lanes; I tried to accelerate going about 45mph, and shuddering real hard. It was difficult to maintain my speed on a level surface. It was almost a total loss of power with no trouble codes.

Just bought my 2013 Platinum 350 DRW 2 weeks ago. 9,000 miles on it. I was cruising along yesterday at around 45 mph in 6th gear going up a slight incline. Truck was fairly low rpm don't remember what exactly. As I'm going up this hill it begins to shudder quite a bit almost seemed like the turbo shuddering while lugging up the hill at a low rpm in 6th. I stepped into the throttle to get it to downshift into 5th and it stopped. I never experienced anything remotely like this in my 2011 6.7.

I have a 2015 F350, sometimes the info center will show what gear I am in and sometimes it won't. Why or what I can do so it shows all the time?

My truck shudders bad between 50 and 60 mph. I have about 7,000 miles on my 2013 F350 diesel. 4x4, single rear wheel automatic. My truck has had this issue since I drove it off the lot. I replaced the tires and wheels with after market 20 inch wheels and toyo mud terrain tires, added a leveling kit and installed a K&N intake at 2000 miles. When driving between 50 and 60 mph with a steady pedal my truck begins to shudder. You can hear the noise coming from the intake, which is not the problem. The boost is registering almost no boost what so ever. The problem mainly occurs in 6th gear with no load or a light load. The entire trucks shakes.
Since I put more miles on my truck each day the problem seems to be getting worse. Not to mention my mpg has drop since I first got the truck from 18-20 to an astonishing 14-15. I took it to the dealer the other day to let them figure it out. They put stock wheels,tires,intake back on the truck for testing. They determined that the shuddering happens between 1400-1700 rpms. They told me they couldn't find anything wrong with the truck and said it was my wheels. They mentioned that with the stock stuff on it was less noticeable. They also said that with stock wheels and tires it went away. Which I know is crap cause I had stock on the truck for 2,000 miles if not more. Now this is a given for anyone who puts mud terrain or all terrain tires on their truck, MPG will suffer some and there will be noise and vibration. However, this is more than a vibration from tires. I have only owned trucks all my life with bigger tires and wheels on them.
I walked out of the dealership having to pay them money because they said it was due to my wheels. My wheels are 0.4 inches off from stock and my tires are the exact same height as stock just wider. Knowing a decent amount of mechanics and how to put my pants on each morning, I was not satisfied with their conclusion. I mentioned if it was my wheels and tires why wouldn't it do it all the time. It's not like I replace my wheels when I'm driving down the road. I believe that they couldn't figure it out so they said it was my wheels and tires to charge me for the time. Just yesterday I was driving on a long trip and it was shuddering, then the cleaning exhaust filter notification came on and the shuddering stopped. I noticed this and tried to make it shudder, couldn't do it. This reinforced my theory that the dealership is less than knowledgeable.

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!

2005 f350 6.0 all stock except egr delete. My turbo is spooling up and down constantly. I can actually watch my VGT duty cycle fluctuate while sitting at an idle too. I've cleared the codes and p0299 always shows up first, but then I'll get p0069 BARO/MAP, and a p0470 exhaust pressure sensor eventually. Sometimes it takes an hour of driving before those show up. I can watch all these values on my torque pro, and nothing seems out of the ordinary other than the turbo opening and closing at will. What can cause this? I hate to just start throwing sensors at it.

I have 07 F350 6.0 never heard this out of any of my 6.0s. it's almost a whine but can hear it w turbo and out of empty exhaust. Almost like a supercharger noise stumped almost leaning towards actuator for turbo? Noise got real loud swapped turbos used same actuator noise is there but much quieter.

I am replacing the turbo on my 2005 f350 6.0. I have the passenger side mounting bolt and the rear mounting bolt out, but cannot get the driver side bolt to budge. I have sprayed it with WD40 and PB Blaster and tried a breaker bar. No luck breaking it loose. I am afraid I might round off the head even though I am using a 6 point socket.

I am on the market for a 2015 Ford F350 with an 11' Royal utility body on the back for my electrical contracting business.
Ford have come back to me and said I need a F450 as I am going with the supercab, the F350 can not handle the 11' utility body.
I have head that the F450 can cost more in Insurance and use more diesel. I contacted my insurance company and they said it wouldn't change to much, this is in CA.
Is there any differences between the F350 and F450 apart from the rear axle and larger brakes. Also if there a major difference in MPG.
I currently have a Ford F150 Limited and love it!

Front Driver's Side
Front Passenger Side
2015 F350 have this issue. I parked the truck in the garage today to do some detail cleaning, and noticed it sagging on the driver's side. Seems like the front coil springs are weak on the driver's side. I called the dealer and they told me to bring it in. They are going to look at it tomorrow. Look at the images, it's almost an inch difference. Truck has never been off-road yet, only has 4000 miles. At first I thought it was a low tire but I checked both tires have 70 PSI. Then I thought it was the floor so I measured from the tire to the fender and got the same results.

I have a '15 Ford F-350 w/ 6.7 - 34k miles. Most of my driving is towing a 30'RV trailer. Today, without any trailer, I was on a local interstate and at around 65 mph on a bumpy stretch of highway the death wobble started. Had it come and go 3 times in a few miles requiring me to slow to about 45 or so to stop it. Never had any such happening prior.

Does the 2015 F350 have the dead pedal on the left drivers side? The one they used to put in to rest your foot on?

I am thinking about changing the Gear Ratio in my 2014 Platinum F350.
History: I traded in my 2011 F350 DRW with 17" wheels and 3:73 gears to get my 2014 F350 SRW 20" Wheels with the 3.55 gears. I pull a 15,000 boat and trailer. The Drw pulled the boat and trailer with no issues. I sold my Northern Lite Truck Camper. I thought I didn't need the Drw any more. First time I hooked up to the boat I felt the difference in between the trucks in the acceleration and fuel economy. Old truck would get 11.5 MPG new truck gets barely 9 MPG going down hill with a tailwind. Over all the new truck is a little slower off the line but when hooked up to the boat it is a dog with the 20" tires.
So the question to you all is; gear change to 4.10? Swapping to this ratio with 20" tires will produce the similar RPM's and possible improve the fuel economy. I get around 18 empty now on trips empty. Around 16 commuting 25 miles to work.

My Father In-law has a 2012 f-350 Dually with 4K miles. He tows a 9K lb camper and until our last trip the truck ram flawlessly. On our return from Myrtle Beach to central NC we were on a freeway traveling at 63 MPH and his tranny would not shift into 6th gear. Tow haul was on. There was some headwind (10MPH) but no large grades or any reason we can think of not to allow an up shift. His display did show a countdown to empty of the exhaust fluid 450 miles to empty.
He took the truck in for service and no codes were found. Dealer did not find any TSB's addressing the tranny issues. Is the sixth gear up shift in tow haul set very conservative? Does it hold 5th unless the load is below a certain value? Other trips we have been on have been mountain towing so 6th gear shift would have been on down hill or level sections. Dealer wants us to bring it to them when it won't up shift next time but dealer is not along a freeway.

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.
