Ford 6.7L Power Stroke Diesel :: 2012 F250 Diesel - Transmission Noise When Shifts Into 5th Gear?
Aug 11, 2012
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.

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.

1st 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.....

Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.
One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).
I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.
These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.
One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.
Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.
Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.
When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.
Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.

My 2012 diesel frequently stalls momentarily after I touch the brake. This is very annoying as I drive in heavy traffic and often have to touch the brake then accelerate to merge into freeway traffic. The dealer service department said this was a 'feature' and not a flaw. Is there any way to eliminate this issue?

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

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?

2012 F250. 15k miles. It's intermittent, speed related, some sort of resonance or harmonic. WoooOOMMmm....woooOoMm, maybe every two seconds at 70 mph. Worn out tires once made a similar sound on a car I owned. This was severe inner wear on the rears. I'm not sure whether it's new or something I just never noticed; it's subtle.

2005 F250 4X4 6.0 .. Why my truck just stopped going when put in gear and the TOW/HAUL light just kept coming on, without pushing it 2 days prior? Now it will not go anywhere, starts great, gas pedal works because RPM's go up when pushing! Just will not go when put in drive or reverse! What else I can do? I replaced cylinoid B in the transmission, speed sensor, and brake switch.

I'm a new Ford owner and my 2012 F250 is my first diesel. Recently, my truck has been having a problem with the engine loosing power, bogging down, shaking-pinging, every once in a while, like 1-2 times a week. When it happens, I can barely get the truck to do 50 MPH. It sometimes happens when the "cleaning exhaust filter" message is displayed, but also happens when it's not displayed. I recently read on the internet about HPFD failures.
What may be happening to my truck? Could it need Cetane booster? Also, how about scheduled maintenance. The owners manual (diesel supplement) says to do the maintenance once the message center says to change oil soon. The dealers here in AZ are pretty much saying 5 months or 7,500 miles. On my other trucks (which were gas), I would stick to what the owner manuals said because I thought how could they deny a warranty claim if you're sticking to what the manual says.

Have a 2012 F250 4x4. Have read many posts about different lifts etc. I don't want to go real big but I would like to go to a larger tire than the stock Michelins.
On a F250, done a 2 inch front leveling kit and switched out the rear blocks to F350 blocks. Assuming I wanted to put new shocks on with this change, what level kit and what adjustable track bar (from what i've read this is pretty much required).

My truck just started to have issues with the gear shift. The gear shift seems very loose now and it is having trouble getting back into the park position. Is this a larger transmission issue, or is possibly a failing part on the actual shift mechanism?

My son has a 2012 F250 King Ranch, 6.7 L.
Little info: Last Friday the inter-cooler hose blew. We changed the hose this past Saturday. The truck ran great all weekend. Last night leaving for work it started to sputter and then died. Got the truck to crank, ran great no sputter, but something under the hood sounded off. We drove it all the way back home. Killed it, re-cranked it, everything was fine.
This morning cranked the truck, ran fine for 5 min then died and would not crank. We decided it needed new fuel filters. Replaced the fuel filters, truck now cranks and idles great. When you mash the gas at it revs up then sputters like it would die, when you let off the accelerator it catches up and idles fine again. It cant be too much wrong, it ran great all weekend.

I have a 2012 F250 4x4 6.7L Diesel with around 114k miles on it. Jut in the past couple weeks it has produced this issue: At start-up/during warm-up it when I make a turn (left or right) and hit at least 40mph the steering feels heavy and pulling to the right, all of a sudden it seems to release and dart a little to the left. It does this for about 10 miles then it is fine. Steering is a little loose, 114k miles and previous owner had a plow on it but once it straightens out it is fine for the rest of the 45 mile treck. Tires are new Goodrich All Terrains, no visible signs of a belt being broke.

2012 F250 Lariat with 18k on the clock. FOr the past two months I've had a temporary side job on weekends and had to haul some trailers. I noticed my trailer gain operates sporadically and if I try and adjust it she tells me there's no trailer connected. I've edited the settings and reset all the settings also. I find this particularly annoying when towing the 4,000 lb trailer but I'm also hauling single axle trailers and it hasn't registered that I'm towing once.

I just bought a set of 2013 20" rims for my 2012 F-250. I can't seem to get the tire fault light to go off. I've gone through the "learn" process but it won't read them. Are the TPMS not the same between years?

My dads 2012 f250 6.7 shakes SOMETIMES at speeds anywhere from 30 to 65mph he had ford look at it they said that everything looked fine, all the normal items were checked. How can something like that just show up for a few minutes then go away for days at a time. He said it shakes the whole truck then he slows down it goes away then speed back up and its gone. He does need new tires and balanced but I would think if that was the issue it would be a consistent shake or am I wrong?

2012 6.7l CC SB SRW 4x4.
Truck has 9700 miles on it, bought it in December of 2012. Twice in the last week, when at about 60 mph on a flat road, maintaining speed with virtually no wind, there is a slow, gradual shudder from the rear wheels. Both times the truck has been on cruise control and if I add power, the truck does not accelerate and the shudder continues to increase. If pull power either by brake or canceling cruise, it stops and the truck performs as expected.
I have yet to have the time to reproduce this. My only hope is if the dealer is already aware. I plan on trying to reproduce it at some point with hopes of having something tangible for the dealer.

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.

I have a 2012 F-250 6.7L w/8K miles. I have been struggling with this issue for 6 mo. The engine feels like its missing at low RPM. I would equate it to the feeling of a bad coil pack in a gas engine. The boost indicator drops to 0 for a split second then recovers. The dealer says they can't find the issue but went ahead and replaced the turbo. After the turbo replacement It got worse. This is an intermittent problem with no codes.
