Ford 6.7L Power Stroke Diesel :: Little Twang Sound Coming From Trans Between 3 - 4 Gear Shifts
May 9, 2015
Having 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?

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

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.

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.

I 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.

After doing some hunting/wheeling with my son, got back to town and 2003 Excursion w/ ~145K miles would not budge in any gear. No codes with Scangage. After 30 minutes I finally thought to rev it up and it shifted hard into gear, and drove normal home. What do do now?

Bought truck for cheaper price with no 3rd gear. Went to a reputable yard and picked up a cheaper trans... It was carfaxed with 185K miles and in a rollover. (This is the last time I try to save a couple bucks by getting a cheaper transmission.)
I believe trans is stuck in 3rd gear...Takes off slow. RPMs do not drop..Doesn't shift...Feels like I'm in 3rd from takeoff. Here are the codes:
P2262: Turbo / Super Charger Boost Pressure Not Detected Mechanical
P2614: Camshaft position signal output circuit / open
P2262 again
P1000 On board diagnostics II Monitor / drive cycle test not complete
P0678 Cylinder 8 glow plug circuit
P0672 cylinder 2 glow plug circuit
P0603 Internal control module keep alive memory malfunction
P0720 output shaft speed sensor circuit
B1676 Battery pack voltage out of range
B1318 Battery voltage low

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.

2001 7.3 auto, 2wdr, 291,000, Transmission sometimes shifts hard from 1st-2nd, 2nd-3rd. Problem started after I found trans dip stick tube broken and loss of fluid. Anything I can do without going to a shop. I've replaced the Broken Tube.

I just bought a 2002 F250 7.3 4x4 auto. It had a TS 6 position tuner installed. In stock mode, I got about 11 mpg. I wasn't too impressed. I found that when I left it in 75hp mode, my mileage went up to 21. I drive easy and try to keep shifts at or below 2,000 rpm. The problem is that, when in any position other than stock, my transmission shifts HARD.
My question is: what's going on here? Does the TS change the transmission shifts? Or is the extra bump in power enough to stress the tranny? Based on the factory gauge, the transmission is not running hot. The fluid is nice and pink with no odors or metal shavings. I'd hate to prematurely kill my transmission, but nearly doubling my fuel mileage is hard to pass up.

I have been having an issue with my 4-5 gear shift under hard acceleration and know that a rebuild is due soon but I was wondering if any high performance kit available with all the clutches and friction discs needed to rebuild.

I have a 2012 Ford F250 6.7 powerstroke. Truck has about 30,000 miles. Has been completely flawless and has exceeded all expectations. Well....I am experiencing my first hiccup.
I traveled yesterday. While going up a slight grade, running about 50 mph, 1000 RPM, 10PSI boost...truck started bucking and sputtering with weird sound coming from around the air box. It felt just like you had a blow out on the front right tire. My initial thought was i just had a blow out as the truck hopping. Well, once i let off the throttle everything went back to normal. It did this about 5-6 more times on the trip. When it would start doing this I would just let off the throttle and everything would go back to normal.
I've read a good a bit on this 6.7 and appears that turbo issues are common. Being optimistic, I am hoping this is something that can be fixed easily. Again, have had ZERO problems with this truck, runs great, and even now on the trip runs fine but now we have this intermittent issue that I do not like. I am very diligent in taking care of my equipment, have not abused this truck and all maintenance is current (actually a bit over kill). What the issue could be.

2012 6.7 F250 with 17k miles. It's getting hotter here and the last couple of days when shutting down there is a sound coming from the engine compartment that sounds like an air pump on one of those load-leveling systems. It will go on for about 15 seconds then stop.

I have an air leak sound coming from I believe the driver side. Sounds like an air line from a compressor leaking. Could see anything obvious last night or hear well over engine. When driving it's pushing more air. Nothing looked/felt loose. Didn't find any air blowing were I could stick my hand in a hot engine. Doesn't seem to have performance issue, maybe a little more turbo delay.

2005 6.0 SuperDuty ... I was driving my truck on the freeway, no issues. Started hearing a very faint ticking sound, then the engine died. Pulled off to the side. tried to start it, and it turned over very rapidly, with no compression. I'm thinking "Timing Gear".
Had it towed to a Ford dealership near the incident. I told them what i thought it may be, and the mechanic thought it "May be possible". not very confidently....
I authorized them to remove the engine, and look. Sure enough, the gears were toast. This is the difficult part.
The service manager is a young kid, (I can tell from talking to him a hundred times on the phone), and is telling me "My Cam(s) are ruined, and the valves are bent, because the metal from the gears went through the motor. I told him to stop. put the truck outside, and wait. So, I have a couple of questions. other than i don't have Cam(s).
1. Is the 6.0 a clearance type motor? (will the valves impact the pistons, if the timing gears fail).
2. Will the metal from the timing gears get into the motor, or fall into the oil pan?
There were no loud noises, when the engine died. I had the engine bullet proofed at 101,000 miles, it now has 250,000. The truck is still solid, so worth fixing?

I changed my fuel filters a couple weeks ago. When I opened the hood the other day i noticed a kinda hissing or sucking sound coming from the engine mounted fuel filter. I've watched epics video a couple time and think his made the same sound but not sure. I am just paranoid with all the hpfp problems. It runs fine and had no long starts or hesitation at all. Lemme know if you all have the same thing. I just can't remember if it sounded like that before. I have done the air purge properly and several times since changing the filters. I notice the sound while doing the air purge procedure with engine off and key on.

What would be causing this clicking sound coming from my front passenger wheel? Wheel bearing? It ONLY clicks when turning left.

I've got a strange squeal sound coming from under the hood only when truck is cold? It sounds like a bearing and after it gets heated up the sound stops. I talked with a guy thats a cummins guy and he said he had a similar issue and he had to replace the bearing in the turbo? Also when truck is warm it will still do it, like for instance, if I run in a store and truck idles for 5-10 mins it will do it only if I romp on it for a short while like 2-3 mins then again goes away. And if I'm idling or in neutral, hot/cold, it does not do it, it seems to be only under a load. Pull a 26 foot boat no problems.

I blocked off the hpop discharge tube to test for leaks, shop air. I am plugged into the oil rail drivers side, and keep getting a slight popping sound. The first time I did this it took ten minutes to start, so I replaced the top injector seals. The second time it did this after about four minutes, so I took the oil rail to the local shop and they did the ball tube orings in the rail, now I went to put it back on and it does it almost right away.
Am I just pushing the oil out of the injectors? is this normal or should I have NO air noise period? I guess I am not sure how these injectors work, where does the oil go after it enters the top of the injector? It seems like it's coming more from the top coil area, more so perhaps than under the oil rail.

What could be making the strange pumping sound coming from under my hood after I shut off the truck?? It sounds like a small compressor or pump running.
