Ford 6.7L Power Stroke Diesel :: 2015 F250 - Engine Begins To Rev Up And Speed Increases But Trans Stuck In 2nd Gear
Sep 5, 2017
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.

I have a 1999 F250 4-wheel drive with a 6-speed tranny. The tranny is several old but has only around 100k on a rebuild. Three times recently it has stuck in 6th gear (overdrive) and I had to get really rough with the stick to get to come out. Afterwards the stick felt "thick" for a while and eventually everything seems to go back to normal. Not for sure but it may have started after pulling a heavy load, around 16k, which is not unusual for the truck. Other than the times it stuck and shortly after, the tranny seems perfect.

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

I just bought a new 2014 f250.
He says since he has purchased the truck the TPS sensor would occasionally go off saying there is issues with the tires. Tires are fine yet the light chimes on after being reset shortly. Been at the dealer for a week and they haven't really touched it I was wondering if there is any know issues.
Also my dad had the truck in 4x4 and when he puts the truck in park it made it a loud clunking noise. Ford is said there heavy duty line was full so they didn't look at that ethier. He needs the truck for the weekend so he is picking it up tomorrow, he will return it when he can but does this sound familiar as well?

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?

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.

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?

The DEF low caution is on and counting down the miles to go but the DEF tank is full. The caution goes away for a start or two then comes back. She's a 2015 F250 with the 6.7L. I love this truck but its starting to really bug me. I don't know if its related but she's been in the shop four times for warranty repairs to the wiring harness in the past couple months. Apparently there were loose connections in a couple of cannon plugs that the've now bypassed which were causing loss of communication between computers...

I've got a stock '15 F250 6.7 w/ the Diesel Site FF67 fuel/water separator and a 50gal Titan Tank. I installed the filter + tank at the same time around 2 months ago; A few weeks ago, I started noticing an odd buzzing/whirring/gurgling noise (both while the truck was running, and while the fuel pump spins up right after turning the key on). I made a quick video of it this morning:
Ford F250 6.7 w/ Diesel site filter DFCM buzzing/whining - YouTube
I thought maybe it was a filter related problem (I got some little black plastic bits in the filter after installing the Titan Tank, despite my best efforts to clean it out thoroughly before installing) - so earlier this week, I replaced both stock fuel filters, and both filters in the DS filter. Didn't seem to affect the noise from the DFCM at all.
I guess my question is - does it sound like this is sucking in air? I've never found any leaking fuel (even after a 3000mi drive from TX to VA and back), and the truck has never complained about low fuel pressure as I've read that some others have run into. But I don't remember the DFCM/low pressure pump being this loud before I installed the new parts.
I spoke to the folks at DieselSite a day or two ago (those guys are great), and they mentioned that sometimes the Ford quick-release fittings work themselves a little loose from the fuel hose during the filter install, and that putting a hose-clamp around the hose+quick release fitting may solve this; I ordered from clamps from McMaster Carr that arrived today, so I may give that a try tomorrow just to see if it changes anything.

I bought my 2015 F250 last November, and this spring my check engine light comes on with the message exhaust system fluid fault with the anoyying speed limitation. Bring the truck back to the dealer and they just say add def fluid, so I just have them do it. 2 weeks later the message comes back, bring it back to the dealer and they tell me it "needs reprograming" they do the work, light goes off. two weeks later light comes on again. Dealer puts in new exhaust sensors and reprograms the truck.
This fix lasts a few months in the mean time the truck shutters really bad under regeneration mode. Talk to dealer they claim its normal. Finally this week the light comes back on again. Bring the truck to the dealer and Ford keeps telling them that it only needs reprograming but that doesn't fix the problem. The dealer wants to replace the computer but ford isn't letting them do it (the truck is still under warranty) . I am starting to get pretty mad when I went out and bout a 65k truck not to have these problems.

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 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.

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 have a 2004 F250 I just had a Ford transmission out in it. when the truck is cold it runs great. buy when it gets warm it gets stuck in a gear, even if I drop it into a lower gear. Also, if I cut it off when this happens and i cut it off it will not turn over as if it's not in gear, in park or neutral, but if I let it sit for about 20 minutes it will turn over and run as it should until it warms up again.

Our temps have hit into the -18 to -25 Celsius... I have noticed that on 3 different occasions now that the truck feels like its locked in 4wd when I reverse out of my drive way.My Truck is an F250 Crewcab with 4800 miles
This all started with the cold weather. At first I thought my 2 yr old was turning switches on while he was up front one time, but it happended again the following morning taking my 5yr old to school...
I back up up about 20 feet and then make a fairly sharp 90 degree turn and then all the way down the driveway to the street...its really noticeably on the 90 degree turn..once I turn to go forward it still seems jerky...same as having 4wd engaged on dry surface while turning..
After a little bit of driving it seems to go away...also keep in my mind that the 4wd switch has never been touched at anytime at all...we have a lightly snow packed driveway but my traction is still fine to where 2 wd is all that's needed
Could it be something in the rear diff "catching and releasing" for lack of a better term ?
Locker issues, clutchpacks...?
As I am typing I also remembered making a right hand turn on dry pavement and it felt like the rear end slipped a bit and then caught again, much the same way it would fell as if you hat one tire on a small patch of ice and slipped as ya took off and then caught as it hit the dry pavement...
