Ford 6.7L Power Stroke Diesel :: Automatic Transmission Hard Shift Second Gear
Well I've been towing for almost 150,000 miles with a 2012 6.7 Lariat 4 wheel drive. Things have been going pretty well with the truck. I noticed some sluggish and indecisive type shifts early on but now I'm worried. I depend on this truck for pulling a horse trailer all over the country and Canada. Just recently I've been getting a hard shift or a thump or a clunk when shifting up or down in to second gear. I'm at about 152,000 miles and did a hot flush with LV ATF at about 148,000 miles. Should I worry or keep running?
I have a 97' PSD I'm thinking of giving a nice paint job and a flat bed but am reluctant to do so due to financial concerns and the fact that some folks may not want to see me pull up in an old truck no matter how nice it looks. My tranny temps have been stating under 200F and I really keep an eye on the temps when running up and down the hills while towing. The trailer is a 35' Gooseneck with a max GVRW or 14,000 pounds. Should I wait for the tranny to grenade and then drop in a built tranny and if so who's building these tranny's stronger than stock? Long time no see but this site has always been my go to for all my Ford truck questions, upgrades, etc.
Ford 6.0L Power Stroke Diesel :: 2006 F250 - Transmission Shifts Hard To A Lower Gear
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.

Ford 6.7L Power Stroke Diesel :: When Engage Low Range In The Diesel / Transmission Starts In 2nd Gear
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.
Ford 6.7L Power Stroke Diesel :: 2012 F250 Diesel - Transmission Noise When Shifts Into 5th Gear?
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 2012 ford f350 SRW 4x4 with the 6.7L. Problem I have just started to have. When going downhill in tow haul the truck at first will hold you back then all of a sudden it starts to up shift at 20 mph it reaches 6th gear pretty quick. I talked to the dealer and they suggested I was pushing the shift buttons, but I am not. They told me to drive it till next week and then they will see if there are any codes in it.

I tow a car hauler that is about 8000 lbs. On my last trip occasionally when the truck would downshift into 5th under a load, it would bang in there pretty hard. Not a smooth transition, not every time just some times. Just wondering it that was normal or the start of a potential issue.

I'm having problems with my 6r140 in my 2011, the truck is an early build around 8/2010 I believe.
After cold soak when shifting into reverse after allowing engine to warm a bit the transmission almost always slams hard into reverse.
After that shifting from 1-3 is awful, the transmission will try to go into 3rd but downshift to 1st then fail to go back into 3rd multiple times. This situation is extremely dangerous when trying to pull into traffic.
Oh and once the transmission gets into 3rd it will skip 4th and go right into 5th. There is only 94k miles on this transmission/truck.
I just bought this truck about a month ago, does this sound like an issue with the solenoids in the valve body?
I'm very mechanically inclined and can swap them if need be but now we're talking few hundred in solenoids and then getting the trucks pcm flashed right?
Also fluid has been changed and I used mercon lv.
Ford 6.0L Power Stroke Diesel :: Random Smoke While Stopped With Transmission Still In Gear
Lately my truck has been smoking at random, it's not very often & only seems to happen while stopped with transmission still in gear (traffic light, etc). And at this time, I believe its a faulty fuel injector (still originals) although not confirmed.

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?

Took my 2011 F250 in to the dealer where I purchased it concerning intermittent misses on gear changes. The dealer had no history or knowledge of problems with shift flares. I was told they would check it out. Bottom line, their checking it out yielded no results, no action, and no "engagement", pun intended, to resolve a serious concern. How did others resolve the issue when it came up?
View 14 RepliesFord 6.0L Power Stroke Diesel :: Transmission Engages Hard On Reverse / Vibration And Some Knocking Sounds On Takeoff
05 F-350 6L .. Automatic Transmission
When I got the truck I noticed it would slam hard into reverse. Ever since it is taking longer to engage reverse gear and now I have to rev it to 1000 rpms for it to engage with a hard SLAM.
I also noticed that if I do a fast take off, there is a knocking sound coming from drive shaft/differential area (like knock knock knock knock knock then goes away). Then a slight vibration ending at around 30 kph (~20 MPH). There is also some oil leaking from the transmission. I added some mercon sp yesterday - it was a bit low.
My guess for the knocking and vibration is the center support bearings and U-joints. Transmission??? One thing I know I am going to be banging away at that shaft but the transmission problem really scares me.
Chrysler - 300 :: 2005 - Transmission Feel Slammed Into Next Gear Without Any Clutch / Car Shudder
My wife and I purchased our 2005 Chrysler 300 Limited in May 2004.Our 300 has over 117,00 miles as of May 2011. It has been a rather dependable automobile.I have enjoyed it almost as much as my HD. We have performed maintenance as close to the schedule as possible.
I failed to drive the car as often as our second car is an used 2002 S430 which had been my primary auto until about two months. My niece and nephew reported to my wife that the car was not "doing something right". No one could really explain, so I had drove the vehicle myself to determine the issue. The transmission had the feel that it was being "slammed" into the next gear without any clutch. Once the car was warmed up, it appeared that when it shifted at 38-40 mph or 48-50 mph, the car shudders. It almost resembles the feeling you get when you run a car across those strips in the road.
I took the car to the dealership where I have had it serviced locally. They replaced a module which had Technical Service Bulletin from Chrysler for noted similar problems. The first module replaced did not resolve the problem. I took it back and they tried again with the end result being same as before I took the 300 into the shop, transmission appeared to shudder when shifting at the midrange gears.
The dealership as another option recommended that the transmission be replaced. I was not confident with their assessment as I had the distinct feeling they were not clear on the real issue.
I took the car to another service shop which I had more confidence in their work. I asked that they check the car for the problem with the transmission as I wanted their assessment. At this point, I had pretty much decided that I would get rid of the car, but did not want to give anybody else the troubled vehicle nor did I want to have to rush to decide on an automobile to purchase.
The second shop recommended the transmission be replaced, as well several other items be checked as there appeared to be oil leaks. The CAM plugs had been replaced as part of the service the dealer performed though the engine area had not been cleaned of the previous oil. That news was alarming, as the price estimate for a replacement engine was around 6500-7000 smackeroos, way outside of my comfort for repair on the car.
I was able to locate a used transmission with only 86k on it through a very gratuitous turn of fate. I digress, however, as the source for the used transmission was available only to licensed shops.
Two shops had referenced a transmission repair shop as one of the best in our small county. I left the car with the transmission shop for their testing, and it came back with their recommendation that the problem existed in either the coil or spark or an area related there.
I again took the car to the second shop and asked that they check the engine thoroughly for any issues with the spark plugs, wires or similarly related issues. The shop reported that the motor compression was at 190 across all six cylinder and the spark plugs and wires were new and there were no issues with the coils.
I am most happy that the engine is in excellent condition. I have planned to take the car back to the tranny shop as I reported the findings to him of the other shop. I am concerned about the transmission, though I am driving it about 60 miles round trip to work about 2-3 days each week. It still convulses at the mid-range shifting but otherwise runs pretty good after that. The car body is in very good shape as is the interior.
Ford Ranger / B-Series :: Transmission Going To Upshift Then Immediately Downshift To The Gear It Just Left
1996' Ranger with 183,000 miles. 2.3 cyl., Automatic, XLT
When I am driving and get to the 35 to 60 mph range, my trucks transmission wants to upshift, then immediately downshift to the gear it just left. It goes back and forth like this till I get where I am going, or after about 10 miles it will stop doing it. I checked the transmission fluid, and it is full and still pink.
I took it to Advanced Auto, and it blew a code of ECL Bank 1 I believe. I looked around the 'net and I think it came out to be the front O2 sensor may be bad/going bad.
Last week while it was warm enough I was driving with the rear window open, and noticed the faint smell of Rotten Eggs (this has been the only time though). Today I drove about 50 miles and basically used a quarter of a tank of gas. I am wondering if the catalytic convertor may also be going bad?
Lexus RC F 2015+ :: In Manual Mode Hard To Upshift When In 2nd Gear?
Driving in normal mode and the transmission in auto. Once the car gets up to temp, (usually at a stop), move the gear selector to manual mode. If you punch it, I have not issues shifting from 1st to 2nd gear, but sometimes, the up shift paddle will need to be hit multiple times in 2nd before the car will shift to 3rd.
It seems to only happen the first time I go from auto mode to manual mode during a drive cycle. It happens on my car and another car I test drove.

On occasion my 2001 Monte Carlo SS will sometimes upshift all the way to 4th gear when leaving a stop sign. Then it will lug & vibrate obviously from being in high gear at a low speed. I can pull over & shut car off for a minute then start it again & it will shift just fine like normal. Then randomly out of the blue it will do it again without any sort of pattern. I replaced the main computer but that didnt work.
