Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sneeze Like Hesitation Just Before Downshifts To Passing Gear

I have a 04, f-250, with a 6.0 liter engine. I have had the Cat removed and in the last couple months it has developed a sneeze like hesitation just before it down shifts to Passing gear, If I push my foot into the fuel it jumps right down thru the sneezing into passing gear. I have changed fuel filter and grade A cleaned my EGR valve. the only Codes it throws is P0403 and P0405.

Ford 6.7L Power Stroke Diesel :: Truck Downshifts To 4th Gear While Towing A Trailer At Interstate Speeds

2013 CCLB, 33,500 miles, stock emissions

While towing a 9000 pound trailer at interstate speeds (75 to 80 in Wyoming), when pulling a hill, the truck downshifts to 4th gear, boost is about 18psi, eng and transmission temps in the 230F range, EGTs around 500C or 935F. RPM increases normally to 3000 then the turbo gets very loud and boost drops to about 10psi. The truck shifts to 5th gear, noise decreases but is still present, shifts to 6th and noise goes to normal after a couple seconds and boost builds normally.

This just started today. I have about 8000 miles towing this trailer and never had this before. I have about 350 miles until I'm home so I'm headed back out. Will play around with manual mode and see what it does. I also took a video of the gauges while this happens. Audio is difficult to discern. I will try to get better audio and post when I get home.

Ford 6.0L Power Stroke Diesel :: ABS Light Kicks On When Hit A Bump

Brakes seem fine even when the light comes on so I'm guessing its more a sensor issue but which sensor? From researching others posts about ABS lights, seems the sensor on top of the rear differential is a common culprit, but I'm not having an speedometer issues, which also seems to be related to that sensor. It used to be if the bump was big enough to kick the cruise control off, the ABS light popped on as well, but now it's only a moderate bump and it will come on. Shut the rig off, re-start and the ABS light clears, until the next bump that is.

Ford 6.0L Power Stroke Diesel :: Truck Keeps Shutting Off When Hit A Bump

My 6.0 powerstroke keeps shutting off when I hit a bump. It's like everything died and reset and I loose all memory to stereo and everything. When I got to work and popped the hood I tapped on the battery cover by the pcm and it shut off again.

Ford 6.0L Power Stroke Diesel :: Driving Along Truck Just Stalled When Hit A Bump

The first time it happened, I wasn't monitoring any PIDs as I didn't have my phone with me. Not really sure if I hit a bump or anything, it just stalled. I pulled it off to the side and put it in park and started cranking. Turned over rapidly but wouldn't start. I started freaking out thinking what am I going to do? Shut the truck completely off and waited a couple minutes and then turned the key and it started right up. Drove to my destination and didn't have another issue.

I'm only driving my truck on weekends as I have a company van and I can't park my truck at the condo I'm living at right now. So sometimes it's a few weeks between drives. This has been the story of my truck use since I nought it 3 years ago. In fact I know my turbo is sticking as the most boost it builds is 20-22 psi. I probably have a sticking injector too, as it smokes unburnt fuel until warm.

So the last few weeks when driving, I've noticed that if I hit a big bump, occasionally it dies again. What I've discovered is that it won't start unless I shut the key off entirely. Meaning, if it stalls I put it in neutral as I coast, shut the key off as far as it will go and it will start up. If I just throw it in neutral and try to start, it won't.

Watching my Torque Pro display, I've noticed that it locks up (like normal when I shut the truck off w/o shutting the Torque app off). The display then has read lower voltages than normal for FMP, FLP, FVP (main, logic and vehicle? can't remember ). FMP is normally at 48.5v and the other 2 hover around 13.9v. The last time it stalled, I noticed 9.3v for FLP and FMP was 23.4. I'm not sure if this is what it shut off at or if I panicked and tried starting it w/o shutting the key off entirely. So please don't take those readings as gospel.

I scanned it for codes, but nothing popped up.

Ford 6.0L Power Stroke Diesel :: Humming Noise From Front Right Side When Hit A Bump Going 65 MPH

So with the hurricane coming to my house I did the balljoints on my drivers side yesterday to prepare to evacuate today. Everything went smooth with no problems. Now fast forward to the drive to Orlando, I hit a bump going 65 and my front right side (ball joint replacement side) starts humming. I pull over and it stops, get out see nothing obviously wrong and start back on my way with no noise to speak of. It happened again and again I just slowed to almost a stop and it went away. Yesterday after the repair I took it on a trip through some crappy roads, the freeway, and all that to ensure she was safe with no problems. Maybe it is the bearing failing all of a sudden (it looked fine when I took it off). I have had a vibration at 55 consistently i think is the tires now that I replaced the ball joints (was waiting to have the tire shop check balance until after the repair) maybe that could be it?

Ford 6.7L Power Stroke Diesel :: 2015 - Shaking Under Slight Load Due To A Small Incline And Loud Diesel Sound

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!

Ford 6.0L Power Stroke Diesel :: Clunk Sound Going From R To P Or R To N

2003 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?

Ford 6.7L Power Stroke Diesel :: Loud Clunk When Shifting Into 4x4

So I took the wife to the pumpkin farm today, and was we were pulling into the grass/mud parking lot, my tires just started spinning. I stopped because I wasn't going anywhere and I turned my truck to go into 4x4(SOTF) and it made this LOUD clunk and then went into 4x4. Everything is ok and I tried it 4-5 after that to see if it would keep making that noise and it did not.

Ford 6.0L Power Stroke Diesel :: Slight Vibration While In Gear

Sitting at a light. I noticed a slight vibration while in gear. Get home. Put her in park and noticed it again. Took her for a spin again. It seems to do it at low speeds, cruising and goes away once I'm on it? What would be a good starting point to track this down?

Ford 6.7L Power Stroke Diesel :: Transmission Clunk At Random Times From Park

It clunks real bad at random times. Whether I have had the e-brake on or not (sometimes even with it on, so I have not put any load on the locking mechanism in the tranny).

Its a 2014... Does not matter if its inclined ground or flat.

My 08 F350 V10 it replaces never once clunked.

Ford 6.7L Power Stroke Diesel :: Loud Clunk / Bang When Downshifting Under Load

38k and 15 months old. Runs fine except...

Can be in cruise or not, tow/haul or not, but need to be pulling a decent hill with 7k+ trailer. Running level with air bags. Regardless of speed, cruising at 50, 58, or 65, beginning incline and turbo boost builds normally to maintain speed to the point when it needs to downshift. BAM!!, not just a clunk, 90% of the time- scares the hell out of me. I can make it do it on an incline empty, but it it difficult. If because initial speed is 50ish, a second downshift to 4th may be needed. A bang only 50% of the time.

No codes.

Regardless of the degree incline, (toughest in the NC/KY areas is 6-7% grade, can avoid harsh shift by backing off on throttle and manually downshifting to 5th or 4th, depending upon speed.

Can "make" it do it on level terrain with 7k trailer if I slowly back off throttle and slow from 65 to 50 or so and punch it, but not too hard. Too hard and it goes to 4th, usually with just a modest clunk. Just right and I get 5th with a loud, and I mean loud BAM. Even the tech was impressed.

Afraid to hook up my 17k 5er and take off for the next 3 months, which is the reason I bought the truck to replace my 11...

Carrier bearing has grease coming out of it (400k on various duallies and never seen this), but dealer says not an issue.

Ford told dealer that it had no idea, and advised tech to do a lot of pin point electrical testing and everything checks out. Next stop is the inner workings of transmission.

I have been without it and work for 3 days because of backlog. Running two day load tomorrow, then back in for tranny work.

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 6.7L Power Stroke Diesel :: Shifting Not Smooth From 3rd To 4th / Slight Hesitation

i bought a used 2011 F250 and really like the truck and there is no comparison when towing the trailer.

1.) I've noticed the truck doesn't shift smoothly from 3rd to 4th. Under light acceleration the RPMs climb, then drop slightly, then climb, and finally the truck shifts into 4th gear. It's almost like the truck wants to shift but doesn't. I believe a selenoid was replaced on the truck.

2.) From a dead stop, when pushing slightly on the gas pedal there is a slight hesitation or unresponsiveness with the truck wanting to proceed forward.

Ford 6.0L Power Stroke Diesel :: Slight Drip From The Blue EGR Hose?

So I recently had the head gaskets done at Ford. All is good but there is a slight drip from the blue EGR hose. It made a 3" circle on the driveway after 8 days. Coolant level is still fine. I really don't feel like dropping it back at Ford. Think I can just twist the hose to tighten it a bit or is a new hose in order? It is only 2 yrs old and was not replaced with the head gasket work.
