Ford 6.7L Power Stroke Diesel :: Transmission Shudder When Push The Throttle In 2nd / 3rd Gear
I have already logged 6K miles on her, crazy, but it's my job. I have pulled 5 maybe 6 trailers (form trailers, about 15K pounds loaded, this time of year). Loaded or unloaded, when I push the throttle in 2nd, 3rd gear, I feel a shudder, like transmission shudder.I know this thing throws down 800 ft. lbs. of torque, should I not be pushing it so hard? Or, what am I feeling?

I am experiencing a pretty noticeable vibration from the rear of the vehicle (steering wheel does not shake and I have no "death wobble") when hooked to my 14K trailer and also my stock trailer (to some degree). Happens constantly whether loaded or not, although it is a bit better when loaded. Happens much more on rougher country roads, but is still there on the interstates.
The trailer is new to me and I rebuilt the entire brake system, repacked bearings & tires have great tread, but have not had the tires spin balanced.
Can't tell whether a shock change (FX4 Rancho) will fix it or not.
I DO get a pretty severe roller coaster deal when hooked up and going over a dip. Truck just continues to bounce tail to nose, tail to nose, etc. That in itself is obviously shocks, but I am more concerned about the vibration.
Ford 6.7L Power Stroke Diesel :: 2011 F250 - Clicking Noise When Accelerating From A Stop?
I have a 2011 F250 6.7 Turbo Diesel I recently purchased. I am hearing a noise when accelerating from a stop. The only time I'm hearing it is when the window is down. The noise sounds like someone is tapping an aluminum pop can. It is easily reproducible as well. I decided to get under the truck and have my wife toggle the transmission from park to reverse. They noise does not occur unless one foot is placed on the brake and the accelerator is lightly pressed. (My wife had the opportunity to run me over and claim it as an accident but lucky me she decided not too). Below is a video. I had a hard time locating the noise. It sounds like it may be coming from the exhaust or drive shaft. The drive shaft does not spin when toggling from reverse to drive but the ticking noise can be simulated and heard when lightly pressing the gas while holding the brake. Something need lubed somewhere?

Ford 6.0L Power Stroke Diesel :: 2007 F350 Running Extremely Rich When Accelerating From A Stop
I have a completely stock 2007 F350 turbo diesel with 98000 miles that i just bought . When accelerating from a stop, it runs so rich that it will barely move and it accelerates very slowly . It burbles excessively and spews black smoke . It slowly builds rpm . As it builds rpm it runs slightly better and the black smoke turns into a medium gray the faster it goes . It takes around 20 seconds to reach 3000 rpm on level ground with the accelerator pedal half way down . Once it reaches 3000 rpm, it runs fine and hauls a_s but looks like it still smokes a little.
The temp gauge stays right in the middle and it does not run hot . It starts and idles fine. The check engine light is on but i have not read the codes yet and can't do that until monday. I have read that it could be an injector that is stuck open but do not know how to check for that. I am a vintage car mechanic and engineer but I know zero about newer computer vehicles and very little about diesels.
Ford 7.3L Power Stroke (1999-2003) :: Shudder / Stutter And Shake While Accelerating

So I have had this happen 3 times so far. As I am driving, and step on the accelerator, I get a very bad shudder in the engine. The whole front of the truck is jumping up and down. Once I slow down it stops and is fine.
It has happened on the following three occasions but it is intermittent and does not do it all the time:
1. driving up a long grade at 45 mph for 5 minutes. I stepped on the accelerator to speed up and it happened.
2. Getting on the highway from 45 to 70 fairly quickly.
3. Once I got on the throttle heavy and got up to 80 MPH. I laid off the throttle to slow down and when I stepped on the accelerator again it happened.
I was not towing at any of these times. I do have warranty still but since I cannot always replicate it, I have not taken it to the dealer yet.
Ford 6.7L Power Stroke Diesel :: 2011 F350 Shudder On Startup?
The past month or two, my garage-kept 2011 F350 6.7 with 38K miles will shudder on startup for a second or two or three then runs normal. What would be causing that? She is my every day driver, but I don't drive her every day. Seems that the longer she sits, the rougher the startup. Last time I drove her was Monday. Started her up tonight to run to the store and she shuddered for about three seconds.

So my 06 6.0 4x4 is just about to break 200,000km and I've done most of the upgrades and work myself. (All the updates are in my Sig). My problem is that when I'm cruising and the engine is at full operating temp, if Im bellow 80-100km/h nothing but as soon as I break into that speed range about 2000rpm the truck will start to shudder. Almost feels like its not firing properly is the best way to describe it. Why this could be happening or causing it?

View 6 RepliesFord 6.7L Power Stroke Diesel :: Pinion Seal Leak And Now Shudder When Not Under Load
Recently had a rear pinion leak and replaced the seal and nut. I jacked up the truck, took off wheels and felt the drag so I could duplicate once i had the new seal as I tightened the nut. I've done this only once before on my F150 years ago, but when I put the driveshaft back on and test drove it, i had shudder when not under load. So when I let off of the accelerator, it had shudder and more the faster I was going.
Obviously thinking this is a preload issue with the rear axle but would this be caused by tightening too much or too little. I had no issues before so I would think that the driveshaft itself is not the issue. I can't confirm that I got it bolted up in the exact same manner as before in relation to the flanges but still wouldn't think that to be the issue.
Ford 6.0L Power Stroke Diesel :: 2004 F350 - Severe Shudder While Under Acceleration
I bought my f 350 new from the dealer and have had many of the problems associated with this truck. Now I have a severe shudder while under acceleration when i either let off the gas or increase speed the shudder goes away. My dealer thinks it is injectors but I have little faith. Shudder seems to be rpm consistent and seems to be in the front end. oh yea it idles great and runs great except at that specific range.

Truck had been running with a bit of a skip and shuddered after throttle was applied and then stopped (would drop to 400 RPM and shake real bad). Had some misfire codes so I decided to do some digging. Where to start looking for air leaks pre upper fuel bowl?

Also, does this mean the air has toasted my injectors?

Ford 6.7L Power Stroke Diesel :: Driveshaft Shudder With Goose Neck - Airbag?
So I picked up a 53' for the racecar. When I'm hauling it on take off I'm getting a pretty good shutter out of the truck. My crew chief who owns a maintenance shop, said it's a known issue, and ford has been shimming the drive shafts.
I talked to the service writer at my dealership and he said it's a known issue and they are working on it. However, he said if they shim the driveshaft, there is a good chance it could fix the problem loaded, but then unloaded I'd have the problem. Is there a setup that's recommended?
I'm towing about 15k, but that's far from the limit of my 450.
Ford 6.0L Power Stroke Diesel :: 2006 - In Tow Mode Tranny Clunk And Shudder?
2006 long bed with LS diff sometimes gets a fairly robust CLUNK! sound and feel when decelerating with tow mode engaged. It only happens once per 20 trips and only about a mile down the road, and it only happens once in a blue moon. It definitely is the rear end making the noise and brief shudder. Otherwise the truck runs extremely well.
I had the pumpkin off and fluid changed with Ford friction modifier added at about 100,000 miles. Truck is at 160,000 now. I just got done with a trip in the mountains of Idaho carrying a truck camper and used tow/haul mode extensively for engine braking and climbing, worked like a champ. This was just one trip of many this summer. This is about the only thing wrong that happens on my truck, but usually occurs before I get very far from the house. Should I just forget about it?
Ford 6.0L Power Stroke Diesel :: Torque Converter Shudder When Hitting The Brakes
I've done the testing of hitting the brakes when the TC is locked and when it's off the shudder disappears. My question is I recently had a trans flush and both internal and external filters replaced. There was a hint of noise before then but it seems it's getting progressively worse. Could it be that they used the incorrect trans fluid? Reading through it seems as if I should follow the steps of dropping the pan and looking for signs and symptoms and then replace with the correct mercon fluid (if that's not already what's there). Then maybe some additives like shudder fix? I just want to make sure I take the correct steps to solve the problem as to not break the bank getting a new TC put in and missed something cheap and easy. Also reading it could be motor related maybe a misfire so just looking for pinpoint the problem.

View 1 RepliesFord 6.0L Power Stroke Diesel :: 2006 - No Start When Died After Shudder - Code P2291?
I have a 06 6.0 no start . I was at a light felt a slight shudder went to take off felt another shudder and it just died. Changed fuel filters, unplugged icp no start still. No code at first now throwing p2291. Fuel pressure is at 62 when cranking. Hooked up air to the icp port and only heard air coming out of both valve covers inlets. Ipr was at I believe 60 to 65% when cranking. Little back round 2 years ago I did the whole sinister diesel top end kit and put the updated parts in. New o rings on everything that took them, new egr valve, standpipes and dummy plugs. On the injectors all new o rings and crush washers. I believe that's everything.
View 11 RepliesFord Transmission :: 2007 E350 - Shudder When Accelerating In OD - Whine In Park / Neutral
Looking for your collective expertise
2007 E350 with 5.4L and 4R70W trans. 107K miles and the fluid has probably never been changed ( my mistake - thought it was 100K interval - finding out from my reading that is def not true ). Anyway, following is recent development (last couple days):
Symptom #1: In Park/Neutral there is a whine. As soon as you put it in P or N, the whine 'spins up', stabilizes, and does increase with engine RPM.
Symptom #2: Hesitation (albeit minor) when starting from stop in D and R, with _very_ minor shudder. Sometimes feels like it's struggling a bit to move its own weight just until it's rolling.
Symptom #3: Shudder when accelerating in OD. No shudder when I turn off OD. It does not stop when applying brakes (a test suggested elsewhere). Also, the shudder does not happen when applying gas while braked in D at standstill. Only at highway speeds (enough to be in OD).
This all started at the end of a trip (90 miles or so in 85-90 degrees) when I was pulling a utility trailer (maybe 2000 lbs loaded). Not sure if related, but traction control warning went off a couple times. I think I have a axle seal leak that may be triggering that.
Otherwise shifts fine (no change in shift behavior or smoothness). Things seem to be worse when it has heated up. Should I start with a fluid change? Wasn't sure because there are comments out there saying don't do it or the tranny will just fail faster (I am skeptical).
Ford 6.7L Power Stroke Diesel :: Shudder When Engine Lugged Down To 1000 - 1100 RPMs On A Hill
I purchased my 2013 F350 PSD July of 2014 and immediately noticed "the shudder" when the engine was lugged down to 1000-1100 rpms on a hill. Sounding like somewhere around the turbo belching air too. At first I was startled but learned to manually downshift to higher rpms and it will stop. Once or twice I tried accelerating out of it and it shuddered as bad as the poster who said it made the steering shudder too.
My truck has 16,000 miles and I never let the rpms drop now. So I figure I have a real problem I'm not imaging. What should I tell my dealer is the TSB or remedy ?
