Ford F-150 (2009-2014) :: Transmission Exhibit Extremely Hard And Abrupt Shift Every Now And Then
Sep 7, 2013
Starting to develop an issue where the trans will exhibit an extremely hard and abrupt shift every now and then - most only during the first couple hundred yards of driving and I think its the 1-2 shift. Only will happen once and only rarely but its becoming more frequent. I have an '11 5.0L supercab auto 4x4, but my father has a similar truck but with the ecoboost which does the same thing on a MUCH more frequent basis. He has been in numerous times with no resolution so I am loathe to expend the energy on "dealing" with them.

2011 F-150 Scab 5.0L 25k miles. Why my transmission is waiting several seconds after being placed into drive or reverse before it actually slips into gear when first started in the morning and why it has a hard shift between 1st and 2nd than again between 2nd and 3rd and maybe why when it shifts into 2nd and 3rd gear it slips back out than back in?

I have a 2014 screw 4x4 v8 that has been in the shop 5 times now for something that the dealership can't duplicate, and that is intermittent enough for me that I can't determine what the conditions need to be in order to duplicate it myself.
My transmission will shift hard under two different situations:
1) when rolling through a stop, or a momentary stop at a stop sign, the transmission holds up between 3 and 1, and when I bring the rpms up, the transmission shifts down into 1, making a hard clunk;
2) at highway speeds, more so when using cruise, if I accelerate and the truck shifts down from 6 to 4, there will be a hard shift as well. In fact, when I'm on a long stretch of flat, open road using cruise at 70-75, I can feel a slight bump through the steering wheel and floorboard, as if the cruise is trying to engage the throttle a bit more, but only for a split second. But that will happen quite a few times within a couple miles until I come up on a grade and the throttle has to engage for a bit longer to keep speed. Sometimes, the hard shift will do occur going to 5 as well, but 90% of the time it will be a 6-4 shift. If the truck decides to shift from 6-3, there's no issue and it shifts and accelerates like it should.
Again, this is so intermittent, but when it happens, it happens several times. I've had the service tech ride in the truck with me, all the while not being able to duplicate the issue. I understand that these are learning transmissions, so the only thing I can think of is when I try to duplicate it by accelerating over and over, that the transmission adjusts the shift pattern or fluid pressure to compensate.

The transmission is shifting extremely hard when it downshifts to make a pass.
Any other time it shifts fine, this is the only scenario it happens in.
It is pretty violent, shifting with a bang.
It is a 2010 corolla, auto, with 70k miles, I have never changed the fluid, and I don't think it has anything to do with it.
The tech said it might be the battery, as it was going bad. I put a new battery in, and it didn't seem to do it for two weeks or so, but is now back doing it again.

I recently bought a 2010 f150 5.4 extended cab 4x4, i noticed when in traffic and the truck goes into 2nd gear just rolling slow when i come back to a stop it bangs going back into 1st?

Any solutions for the tranny/rear end hard shift from 1st to 2nd at low speeds on a 2011 f150xlt / off RD package with the 3.73 rear end/ elec lock. Had FORD do an update earlier and seems to be worse !!!!!. I will get a bang out of rear end when going over a speed bump and tranny shifts to 2nd. I am bringing back for warranty service and would like a some information to be educated before going.

I have a 2011 Super Crew, 5.0, 4x2. I've been told this hard shift at low RPM and speed like idling through a parking lot is normal? We bought the truck used a few months ago and I've been told this is normal.

My 2009 Santa-Fe AWD Limited is sick! Starting from a stop, the vehicle has abrupt shifts with the transmission slipping (RPM revving). Seems worse when cold. Checked the fluids, and found ATF fluid in the engine oil and engine oil in the ATF fluid. Quick internet check suggest a leaky vacuum modulator valve. (There is no way the fluids went in the wrong holes, the vehicle only has 69k kilometers on it, so it still has original ATF fluid, and I recently changed the engine oil myself.) So, do you think this is the correct diagnosis? How hard is it to change the modulator, and where is it located?

I had a clutch, slave cylinder, and master cylinder replaced about 20,000 miles ago. Everything seemed to be working fine until I drove across the Rockies. The transmission was extremely difficult to shift, and the vehicle would actually roll forward when cranking the engine at fuel stops (temps were minus twenties). Once I got out of the mountains on both ends of the trip (where it was warmer), the clutch worked normally. The local Ford dealer found lots of air in the hydraulic clutch system, bled it, and it worked fine for several months.
The clutch is doing the same thing currently, but not all the time. Some days it's fine, other days it's difficult to shift although double clutching seems to work. It gets particularly hard to shift after a long drive (e.g., interstate driving for a couple of hours). I took it back in this morning to see if the dealer could figure out what is going on, they're saying it's likely a bad slave cylinder. I've heard the 1995 Explorer clutches are a bear to properly bleed, and can't work but think there may still be some air in the system.

Long time listener first time poster. My wife has a 2009 Vw jetta 2.5 with a manual transmission that is very hard to shift. It has 80,000 on it and has had the clutch replaced once. She told me that she never had any problems shifting until she let it sit for two weeks while she went to cape cod. I have driven it myself and can confirm that there is an issue. Sometimes it just will not go into gear. No grinding noise at all and very very stiff when moving the stick shift laterally from first to fifth. Not actually shifting from 1-5 just moving the stick across the range it feels like cement. I have already changed the transmission fluid and used the Vw oem oil. I also removed the shift boot and lubed all the moving parts with a high quality grease. Tomorrow I am going to bleed the clutch slave and have a good look at the shift linkage. Is their something I am missing?

I have a 2009, 4x4, 5.4L with 78k miles. The transmission works overall but it seems to shift late and creates a mushy feeling. If you put your foot down, it will downshift and take off so it's not a power issue. As I've read on this forum, mine also searches for the right gear often and overall seems to shift too much. Seems like a computer reflash would fix it as I think it's just the shift timing. Computer reflashed? Is this possible or available from the dealer?

I have a 2010 Chevy 1500 extended cab. For a few years it was a daily driver. It has 54000 miles. For the last 1.5 years I have been driving a company vehicle so my truck sits a lot and usually only gets driven once a week when I'm off running errands and such. Recently if I drive it just around town a few miles here and there, everything is fine. But if I drive it to a farther location say 20-30 minutes away the truck will start to shift extremely hard into second gear from first to second. The first time it happened I though I got rear ended by another car only to look around and no one was behind me. I wouldnt think the trans. would be going out at 54000 miles.

My Toyota corolla 2011 started to shift a bit hard from first gear to second gear and sometimes it feels a bit like choking since November of last year after I started to commute about 38 miles to work. It happens when I am taking off and going straight and it doesn't happen when I am turning left or right. I have taken it to the dealer once, they reset the transmission computer, but it still felt the same and the way the other gears shift felt a bit differently.
I have seen a similar complaint about the same issue of gear shift from first to second in the NHTSA website and another forum with the same issue with a 2009 corolla with a seemingly loose motor mount.

So, coming home tonight, I had a new error pop up that I haven't seen before - TIRE PRESSURE SENSOR FAULT - combined with an extremely irritating flashing TPMS light.
I had new tires put on last week... have right at 102K on the truck now. It's an 09 XLT Screw 6.5' bed 4x2.
What will be the possible cause? Is it at all likely that the sensor was damaged during the tire install? I don't want to give the tire shop a hard time if it wasn't their fault, but the timing seems a bit of a coincidence.

This is on my 7.3PSD. I've observed that the 1-2 gear shift drops about 1,000 RPMs and takes a good half second or longer to do so when given a lot of accelerator pedal input. And then the 2-3 shift is a very quick and harsh shift.
If I am accelerating gently the 2-3 shift is as unnoticeable as the 1-2 shift is quick. Is the slow 1-2 shift causing the trans to protect itself and affecting the 2-3 shift? And if so, what do I do to resolve all of this? I changed the trans fluid a week ago and there is no change.

I have a 2006 Chevy 2500HD with about 180000 miles. All of a sudden the transmission is shifting extremely hard at times. It doesn't shift this way all the time. What could be causing this problem? It doesn't have to be under hard acceleration either when it does shift hard. It sometimes is during hard accelerating and sometimes it is under very little acceleration, but as I said it doesn't do it every time. When it does shift hard, it seems to do it in all gears.

Could my brake issue be related to my transmission problem? Neither are constant. Brake problem= sometimes the brake pedal feels hard, like there's no power brakes (I drove a car once. ..looong time ago. .. that had no power brakes or steering) but it will kick in after a short distance. Transmission prob= seemingly unrelated, is a problem shifting from 1st to 2nd gear. This has happened maybe a 1/2 dozen times, the first time and mostly when in heavy commute traffic and when going between 1st and 2nd gear because of the slow commute speed, but also at other times when not in lengthy slow commutes. When it doesn't shift, the odometer doesn't work (shows only dashes) and an engine light comes on (the sprocket/gear looking one). Usually the transmission will eventually shift and the light goes off.
I read that the brake problem might be a vacuum hose problem? Something about a booster? Is this dangerous? or is it like having a car w/ no power brakes? Going to have my transmission looked at this week. Read on another site about dropping valve seats on this year car. If there's a major transmission problem, I'm wondering if it's worth fixing? I changed, timing belt, water pump, front and rears brakes, tires. 143,000 miles.

I have a '99 F250 SuperDuty Diesel with an Automatic Transmission. There is a button on the end of the gear shift which allows you to turn off overdrive -- in other words the transmission won't shift into overdrive once you press the button.
Here's my problem. I start off driving normally. I've not done nothing to the overdrive button and the truck shifts normally into overdrive. 10-15 minutes down the road, the overdrive light (which indicates the state of the overdrive button) is FLASHING. Pressing the button doesn't stop the flashing. Once this flashing starts, the only thing I notice is a much more abrupt shift from 1 -> 2 gear.

I asked a question about the E40D a while back about a hard 1-2 shift. However, I needed to replace the shift lever to get my OD light operational again. I fixed it and the issue seemed to stop for a while, so I just forgot about it. It's back again, last time it did it, it was hard enough to make the whole truck almost buck. It was a real good bang. So, could this be the 1-2 accumulator piston or the bore it resides in?
The next question I had is how long should an E40D take to shift from second to third? I've noticed on a steep onramp with some throttle, mine can have around 2.5-3 seconds of rev before it finally shifts (unloaded). I could of sworn I watched the tach climb a hundred revs or so during this once (real steep onramp), however maybe I was just dreaming, as I've never replicated it. Just wanted some opinion on this, wondering if I need to start putting some funds aside.
The truck has about 139K and the transmission looks to be original. It was used to haul a camper and a boat most of it's life, or at least that's what I was told.

I have a e99 7.3. had the transmission rebuilt a couple weeks ago by a local shop. have been getting some hard shifts between 2nd/3rd when lightly accelerating. Took it back already but they couldn't find anything. I am planning on taking it back again but what it is so it gets fixed right. What is causing this or what it might be? Should I be worried about having this shop try and fix this?

I just recently bought a 95 F150 with a 351. The truck has high mileage, about 190k, and I am not sure how long the transmission has left. It rides smooth down the road, but when I put the truck into reverse it hesitates for a moment then makes a loud clunking sound(as if a door is being slammed) and then jerks into gear. The reverse works great at the moment though. Should I be worried, is there anything I can do to fix this?
