Ford F-150 (2009-2014) :: After Shifting Lose RPM?
Sep 8, 2016
I have a 2014 F150 ecoboost with a 3 inch lift and 33 inch tires. It seems that in every gear minus 6th that when I shift it shifts to normal RPMs then the truck sort of bogs down, losing 300 or so RPM, then keeps going like nothing ever happened. There are 58,XXX miles on the vehicle. I have taken it to Ford multiple times, now they are saying I probably need an aftermarket tuner to take care of the issue because of the bigger tires.

For the last few months my truck shifts rough between 2e and 3e gear. However it only does this first thing in the morning, when I leave the house I speed up until the end of the street, then when I let go of the gas it'll rev up a bit and shift from 2e to 3e while making a big clunking noise which I can definitely feel ...
It does it sometimes very rough and sometimes just a little bit. I used to not worry about it but i'm starting to wonder if something is wrong with my trans. Could it have something to do with the slip yoke?

Used to own a F250 so I am new to the F150. I am currently in a 2014 F150 fx4 with about 10k miles on it. I noticed when the truck is shifting into 3rd (normal acceleration)the rpms once in third remain around 1800 then drop to 1400ish after about 2 seconds or so while still in third (almost like its shifting again). What it is?

I just picked up my 2011 FX4 Ecoboost with the 4.10 axle ratio. While in drive, the transmission will not shift into 6th gear until around 65mph. The rpms in 5th gear at this point are around 2300(ish). If driven with Tow/Haul mode on it will shift into 6th at 45mph and lock the converter. If traveling at a speed in drive (no T/H) where you would think it would be in 6th, lets say 50mph on flat ground, and you force the trans into 6th, either by using manual mode or T/H, and then return the transmission to normal drive mode it WILL hold 6th just fine with the converter locked and will even accelerate holding 6th.
If you accelerate more rapidly and the transmission downshifts, it will not return to 6th until forcing it to do so by one of the two ways above. I realize that the truck has adaptive learning strategies, but this doesn't seem right. It also has only 300 miles. Initially I had even thought that this might be some sort of break-in programming, but not anymore.

I recently purchased a '13 FX4, i love the truck, the Ecoboost power is incrediable. Recently while passing someone it made a horrible grinding sound, the dealer advised that it was known turbo issue that should have been corrected before we took delivery of the truck. When we took it in the dealer called and said they have Ford corporate involed because when the truck reaches WFO the four wheel drive tries to engage. Said it might be soem sort of vacuum issue.
Specs : 2013 Ecoboost Screw FX4 short bed. No mods, 6500 miles.

I have 2012 F150 5.0. Was going to do some errands yesterday. Got 3 miles from my house and all of a sudden the transmission would shift from say 5th gear down to 2nd. Then it would shift up to 6th then back down to 3rd. It was shifting all over the place. I did shift it to manual it seemed to stop it a little. But then it would shift by itself again .I went directly to the nearest Ford dealer. I did not shut it off, so if there was a code there they would see it... No codes. The Ford dealer will look at it. Any thoughts?

I have a 2013 F-150 Lariat 5.0 L, 6 speed auto transmission crew cab truck with 44,000 miles on it. Recently I have experienced problems with the transmission not shifting properly. Three times when I have started out of my driveway, it has shifted into 2nd gear while I am going only 2-3 mph up my driveway which is about a 10-12 degree incline. It stays in 2nd gear even if I stop. When I pull out onto the highway, it shifted normally into the remaining gears. Then, the other night as I was returning home, while traveling up the road, it shifted into 5th gear and stayed there even when it needed to downshift. A wrench i-con appeared on my screen, my odometer showed dash lines instead of mileage and my seatbelt i-con appeared. When I got home, I shut the truck off and restarted it and everything was normal again. I have driven the truck a couple more times with no issues. The transmission shifts normally. Could a sensor be going bad ?

My son has a 2013 Fx4 crew cab 4X4 ecoboost with 8500 miles. He says in the morning for the first couple of miles while accelerating gradually the trucks shudders when shifting gears. After a few miles it goes away. Dealer says they can't do anything endless he can duplicate the condition. He went out of town for a few days and left me the truck so I'll drive it in the morning and see what it does.

I recently noticed my brand new truck with 5k miles has been making a humming /vibrating noise when shifting and when RpMs are above 2k. What this could be? It's a 2014 F150 stx 3.7 ....

2014. Noticed the feel and sometimes clunk when shifting to 4 high? My house sits up a hill and this time of year, routinely have to use 4X4 to get up. There is a little more noise and vibration than im use to. Usually shift coming down a semi flat dirt/ice road at low speeds, typically about 10mph. Going in for first oil change soon and was gonna ask them to check it out for peace of mind.

A couple months back I purchased a 2010 F150 XL with the 4.6 2V engine. It has about 112,500 miles on it as of today. The problem I am seeing is in the trans. Normally around town there is no issue other than it seems to shift from 1st to 2nd kinda quickly. That is of course you get on it harder, and then no issue at all. The real issue comes after driving for more than 30 to 40 mins. My wife and I took a little day trip that required about 45 mins of highway driving. The truck performed perfectly. Cruising at 75 to 80 there was no issue at all. When we reached our destination it was more stop and go type driving.
It was then I noticed that when pulling away from a light the trans was not shifting from 1st to 2nd smoothly, but rather with a jerk, or bump. Not horrible, but definitely noticeable. Again if I really put my foot in it it did not do it. All other shifts seem fine just 1st to 2nd. The trans temp gauge was steady in the normal range, and this was on a pretty hot day, in the 80s. Since I bought the truck used I cannot say with any certainty what servicing it has had, but judging from the condition it is in I would guess it was well taken care of.

So today I had a scenario where I had to pull out from a blind corner onto busy street. By the time I pulled out I realized an SUV was coming down the street fairly quickly. My immediate instinct knowing I have 360hp on tap was to put the hammer down.
I basically planted my right foot to the floor and held it there. The truck was already rolling out of the lot and turning into the street at approximately 5-7 mph. This resulted in the truck shifting hard from rolling in 2nd gear, down to 1st. I never drive this way so what I'm asking next is if this is normal or not. As I held my foot to the floor through 2nd & 3rd gears the truck seemed to blip the throttle at 4k then up-shifted from 1st to 2nd gear.
I have a stock Ford Raptor exhaust on my truck with the resonator deleted and when the truck blipped the throttle just prior to the up shift, the exhaust "popped" like a race car with an open exhaust downshifting from speed into an apex. Yes it sounded cool, but it was obviously cutting fuel or throttle for some reason.
So here is the weird part, out of curiosity I tried a few different scenarios just to see if something was wrong with my truck. *Note if I just mash the gas from a dead stop there is no fuel cut going from 1st - 2nd gears at WOT. The fuel cut only happens when I'm leaving out and getting on the gas from a turn.
If I turn off the traction control or advance trac and stability program then there is no fuel cut or 4k rpm, the truck just runs out to the 5600 or so redline seamlessly. Im just wondering if the traction control or torque management is really that sensitive or aggressive? I mean it was 70 degrees out and the road dry, plus I was already at a speed 45-50?? mph where a loss of traction would not be an issue so what gives?

When flooring with 1st or 2nd gear engine suddenly lose power, smoke like hell (white smoke) and engine start to shake badly? It disappears after few minutes when engine turned off. When cold it will go in "that" stage almost on every flooring. When warm it possible will start to shake a little and disappear after a minute without turning off engine.
After CCV breather valve(was broken) , turbo and nozzle replacement this problem still exist.
What could cause that problem?
*Golf mk4 AHF 81kw with new turbo, new bigger nozzles and chip.

Was doing nitrous passes the other day and all of a sudden the car started to lose power. I let off the gas and the rpm's got lower and lower, until I cut the car off. Let the car sit for a bit and tried to restart. Car will turn over but will not start. Threw two odes p0300 random misfire, and p0101 mass or volume air flow circuit range/performance problem. I also smelled slight burning for just a second. I am thinking it has to be MAF or a burned up plug. Has to be air, spark or fuel related. Any of the nitrous guys out there ever run into anything like this? Want to eliminate the small things first. Hoping there isn't a larger issue.

Just purchased a 2010 Toyota Corolla S, 41k, automatic. When I'm going down a flat road, at about 30-35 miles per hour, with a constant pressure on the gas pedal, the engine seems to momentarily lose RPM, just for a moment, almost feels like the A/C compressor is kicking in but not quite, another description is it feels like clogged injectors. All other speeds seem to be ok, kicking the throttle to the floor results in smooth acceleration, I'm actually impressed with the amount of power the engine has. Is this normal? Ive purchased some lucas fuel treatment and have added it to the tank. Throttle response seems ok, I've read about throttle controllers however I'm not sure that would fix the problem, if there is one. Hoping it's a characteristic of the vehicle.

I own a 2009 Nissan Sentra with a CVT transmission. It has about 65,000 miles. During the warmer months, my wife and I have both experienced times while driving (usually for more than 2 hours) when the engine would lose power while going up a hill. After doing some reading we learned that this was common in Sentra and Rogue models with CVT transmissions. Apparently the transmission fluid heats up, boils, and foams. The foam triggers a sensor that cuts power to the engine. Once the fluid's temperature decreases the car performs as it should.
We have visited the dealership and even have a case number with Nissan consumer affairs. After many appointments and phone calls, the only action taken was decreasing the level of transmission fluid. This action was approved by Nissan. This has worked a little but the issue still occasionally persists. For the record, neither my wife nor I are expecting this to drive like a race car. We'd just like it work correctly. I know Nissan has extended the warranty on this and many CVT transmissions.

Started a while back and comes and goes. Only commonality I have found is the truck needs to be warmed up for it to happen and usually after a few hours of driving. The downshift from 5th or 6th into fourth, at times, produces anywhere from a light to violent clunk, feels like a typical tranny slip. It will do it while in cruise and it will do it if I don't have the cruise on. Can't figure out if it is going to be a tune issue or hardware.
It does it only downshifting into 4th from 5th or 6th, no other downshifting is a problem and usually the 6th to 4th produces the worst results. At highway speeds that is usually a shift from around 2Krpm to just over 3K rpm (6th to 4th) if it is from 5th it is about 2500 to 3K. Start from a stop and go WOT and there are no issues.
Having it in Tow/Haul or not makes no difference as far as I can tell. IT can do it on one hill and the next time be just fine or do it 2-3 hills in a row. After this last trip it will do it at 9K feet or at 60 feet elevation, didn't make a difference there either.
Another issue that may be hurting the computer is the truck originally came with the 235 tires, it now has 285's and the rear is only 3.31. I plan on going with 265's and maybe still a gear change to 3.73's in the future. I usually only notice this on long trips, first was a 1500mile hauling an ATV, second was last week during a 2500 mile empty. Although I have had it do it a few times locally. I figure those bigger tires can't be good especially with that high of a rear for the management system.

Ok, so in M mode shifts can be a little rough from 2nd to 3rd unless I give it enough gas. It's no big deal and my car has always been like that (owned it since 9/2013). But as of yesterday, shifts have completely changed from 1st to 2nd. It is clunky, extremely quick and lurches forward every time in M mode. It has NEVER done this before and it kinda sucks.
I've read all of the threads regarding tranny fluid, belt squeak, etc. and haven't specifically found anything like this. I haven't done anything to the car except the ELF recall and an oil change about a month ago.

What's the best way to be faster when you shifting using pedal shift or stick shift on automatic transmission? Release the gas pedal before shifting and then hit the gas pedal again (just like driving manual), or keep flooring the gas pedal while shifting?
