Ford 6.7L Power Stroke Diesel :: 2011 - Transmission Jerks Every Time When Shifts Down
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.
Ford F-150 (2004-2008) :: Transmission Shifts Out By 20 MPH
I have a 2004 f150 non heritage with a 5.4 its an ext cab lariat auto. It has 350,000 but has been well maintained. The truck runs perfect except sometimes I will hop in and start it up and when i take off it shifts through all the gears before 25mph and when i come to a stop it feels like it downshifts all at once and when i stop it will die. Again it only does this occasionally and the rest of the time runs A-1. This leads me to believe its an electronic error but it is not throwing any codes and cannot get it to replicate the symptoms for my mechanic.

So I noticed that my transmission shifts (jerks) a little rougher than the 3 previous Lexi's that I had when shifting into drive or reverse when the car isnt fully warmed up. Is that "normal?" Had 2 ESes and 1 RX and while I do feel a slight lurch, the GS is a bit rough. I usually let the RPM drop to 1k before driving off on warm or cold days.
Separate incident: I recall at one point, I was going reverse, stopped, quickly shifted into drive and gave it some pedal (not full throttle) and felt a noticeable "bang" and violent lurch forward. Could that have hurt the transmission? Is the computer smart enough to prevent damage? I'm thinking this might have been the cause of it.
Mazda - 626 :: 1991 - Transmission Hard Shifts From 1st To 2nd - Jerks When Driven For A Bit
A while ago, I acquired a 1991 Mazda 626 automatic (currently 105,000 miles) that now has what appear to be the beginning of transmission issues. It hard shifts from 1st to 2nd - the shift jerks really hard when the car is cold but once I've driven it for 15-20 minutes the hard shift almost disappears completely and stays that way as long as the car is warm - except for stop and go traffic (Seattle traffic) than the hard shift comes back no matter how long I've been driving. The only other shifting issue I notice is on the hills where it seems to shift more frequently than I might expect it too.
Other than what I've described this car is in perfect condition inside and out, as well as engine-wise. My question is on transmissions and whether I should get a rebuilt one. I've taken it to multiple transmission shops and almost all have told me two things 1) I need a new transmission and 2) that the issue is a hard component problem and I could most likely drive this car for months or years without having to replace the transmission - if I want to put up with the rough shifts. They recommended just driving it until the transmission goes out and then replacing it.
Saturn - Vue :: 2003 - Transmission Jerks And Shifts To A Higher Gear
Only during the summer, my 2003 Vue transmission jerks and shifts to (I believe) to a higher gear. Mechanic replaced the computer "harness" but it did not solve the problem. The car has little power to accelerate from a stop. I usually pull over, turn off the motor, and restart the vehicle.
View 3 RepliesFord F-150 (2004-2008) :: Transmission Bang When It Shifts And RPMs Drop To Lock Up Range
Truck is 04 supercrew with 5.4 and 140,000 miles. I have the typical shutter when cruising 55 - 60 and just ease on the throttle to pass someone. I chalked that up to the torque converter unlocking, if I punch it instead of easing into it, it will not shutter. As of yesterday, it acts like the converter is going to full lock up almost immediately. It will bang when it shifts and rpm's drop to lock up range. A few times it has killed the engine when I shift into D. No codes at all, I removed the programmer and installed the stock tune, no change, unhooked battery, no change, fluid is good, and twice after leaving stop signs it worked perfect until the next stop. I believe that it is an electrical control problem.

View 3 RepliesFord Transmission :: 2004 F350 - Jerks While Approaching To Stop And Go?
Bought my first Diesel few weeks ago and I am trying to figure out if something is normal. Its a 2004 F350 and the truck seems to jerk a little bit when I come to a stop and when I hit on the gas. Feels like a tug every time into gear.
I would like to say its first to second but it cant be because its basically only happens when I press on the gas and start rolling, unless I am going into second immediately thats not it. I know less than dick about this truck?
Ford F-150 (2004-2008) :: Jerks While Reacceleration Around 50 Mph?
Only happens with following sequence:
Accelerate up to 50's mph, let off accelerator, then re-accelerate..especially on an incline. Get a rough jerk motion until I either let off the accelerator or accelerate hard through it. It doesn't seem to occur when the Overdrive is on. No codes are thrown.
Been to two shops, one a general shop to diag the engine and to tranny shop but neither was sure. I guess I'll have to go to the dealer but I was curious what others think of the problem.
Ford F-150 (2004-2008) :: Bucks / Jerks In OD Around 40 MPH When Accelerating
Truck is 08' with 5.4, 3.55 gears, auto trans. 84k miles. Recently purchased from the TSA fleet trucks, so I have no clue what PM procedures were done prior to me getting it.
I noticed the following: when I get the truck into OD and then slowly decelerate (meaning I let it coast and im not braking) to about 40mph then get on the gas (normal acceleration) the truck bucks hard almost like when your spinning wheels on snow or ice and put the truck in 4wd and the front rear locks. or a limited slip rear that catches when one wheel is spinning.
if I accelerate hard the truck pushes thru it and doesn't buck as bad. I have searched this out and there are several threads about it that describe just about exactly what im talking about, the following have been brought up as possible problems:
1) bad spark plug/s and or coil/s
this seems to be the most common answer to the possible problem.
2)broke valve spring
3) bad torque convertor
So at 84k miles im thinking replacing the spark plugs would be fine to do as a PM. So coils.............should I just go ahead and replace them as well? I found them (motorcraft). does that seem right?
As far as spark plugs, I have already read the horror stories on the 04-08's breaking the plug in the head. I have also read that before 10/07 was the trucks that had the issue. my build date is 02/08. am I good to go with normal removal of the plugs? the best method I have read for removing them is spray carb cleaner down the hole and let it soak overnight and then the next day drive the truck get it nice and hot and remove them right after you park it,,,,
Sonata NF (2006-10) :: Transmission Jerks When Downshifting (intermittent)
My daughter has a 2010 Sonata with a 4 cylinder and an automatic transmission. She is pretty frustrated with an intermittent problem. Every once in awhile, especially if the engine is cold, the car jerks while slowing down. She believes it is the transmission when it down shifts. I have driven the car and have not been able to duplicate the problem myself. The dealer recently changed the mapping for the transmission in hopes that would work but it hasn't. The dealer hasn't been able to duplicate the condition either.

It just started doing it the only way I can seem to figure out how to explain it is at about 50 to 60 under slight acceleration or uphill it bucks or jerks like you have a trailer jerking. No check engine light this thing is driving me nuts... 2004 f150 5.4 ...

2004 F150 XLT 4X4, 5.4, 142,000 miles... Plugs had been changed at around 75,000 miles... Shell gas used 99% of the time.
Shudders and jerks going up inclines (big or small). Bad gas is being reported at all the local stations...Started using Sea foam and Lucas fuel line cleaner/ethanol treatment. After three tanks of that, I ran tank down till low fuel came on, kept driving, and no more shudders/jerks and ran great while low fuel light was on.
OK...decided to fill tank with Non ethanol gas this time (not Shell gas), added Sea foam and Lucas fuel line cleaner, and shakes, shudders and jerks all the time now.
Before no check engine lights came on but for once when I romped on the pedal once to blow it out, but it went off once I let off. Today going to work, entering traffic, engine light came on, blinked and stayed on. Truck now shudders and jerks all the time when I give it gas, and can only drive like Paw Paw to keep if from doing that.
Local shop ran test and #7 cylinder is not firing and two lean fuel notices. It will be Tuesday before they can check and if needed, replace coil on #7 cylinder.
I'm thinking of installing a new Fuel Pump Control Modulator as per a thread I read here, but only after they check/replace the coil. AND ALSO...turning the OD off did stop the shutters/jerks.

View 3 RepliesFord 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.

2006 STX 4.6 .... I recently changed my oil a couple of weeks back. I've noticed spots of oil on the driveway. I thought it may be coming from the oil pan drain plug but i checked it and it seems to be coming from where the transmission connects to the engine. Lotta oil on the bell housing. That's where it looks like it's dripping off of. Could it be the rear main seal?
View 1 RepliesSonata NF (2006-10) :: 2008 - Jerks When Slowing To A Stop
When I slow down to stop my 2008 Sonata it jerks. It is an intermittent issue. The car has 95,000 miles and when I called the dealer I was told they would start with changing the transmission fluid and go from there. I read on some other posts of this same type of issue being fixed by installing the latest software for the transmission, but this was related to 2009 & 2010 Sonatas. Is it possible that installing some new software would work on my 2008?
View 1 RepliesSonata NF (2006-10) :: Transmission Harsh Shifts When Cold
I bought a 2010 GLS 4cyl and within the first week started having shifting issues. Initially it was only when it was colder than 30 degrees outside and would only shift harshly between 1st and 2nd. Once I had driven a few miles and warmed the car up, everything was OK. It's still an intermittent issue, but now it will do it when outside morning temps are in the 50's and 60's.
I've read the TSB for 6cyl 09's and saw a post in the Santa Fe forum that sounded identical, so at least I'm not the first to experience this.
I took it back to the dealership knowing it probably would not shift badly when they test drove it because we had run out of cold mornings. I picked the car up after they reset adaptive learning and said there were no updates available for the computer. (And also being told I had bad gas in the car. Another story for another time...)
Until it starts doing it at fairly regular intervals, there isn't any use taking back to the dealership as it's very inconvenient for me to get there.
I checked the link that had TSB's and didn't see anything for the 2010's. Also, is there any place where I could check and see when software updates come out and what issues are addressed?
