The tranny is on a 1997 f250 psd 222K miles it has acceleration shudder and o.d shudder. Tranny is getting to 250 degrees Fahrenheit and stays right about there but does not cool when it is park and idling.
View 2 RepliesI have a new to me 98 F250LD with the 4.6/4R70W. I have maintained this truck fro my FIL as best as I could get him to spend (neglected). Filter and fluid replace with Mercon VI last year due to 2-3 shift slip.
He gave me the truck after it would not climb a hill, just hit stall speed and would not move up a steep hill, as I understand it. I put Seafoam trans tune in hoping it would free up sticky solenoids or valves in the VB.
I finally got it registered in my name and drove it to work and back today. After about 25 miles highway driving it shudders pretty bad trying to climb a hill at low speed.
It seems to me that at this low speed, torque converter lockup should not even be a possibility. I do not have COP, but rather a single coil pack. I replaced the wires and plugs for Dad a few years ago, but some shady shop later told him that I didn't replace the left rear (to make an upsale I suppose). Not sure what they may have done in there.
I have scanned with my ELM 327 and Droid using Torque Pro, and the only Fault is EGR flow.
When I first bought my 2001 f150 a few mos ago there were no problems but I did notice once in a while it would give one little shudder when id accelerate. now all the sudden it shudders after around 20 mph all the way up to whatever the speed limit is. Then it smooths right out until I have to accelerate again. if I punch the gas and kick it down it will clear up but then it feels more like a surging going on.
I had the cruise set at 70 the other day and I had to slow down to merge to around 50 and when I hit resume it really started shaking bad and the service engine soon light flashed on and off for a few minutes then went off and hasn't came back on again. I took it to advance auto and no codes showed up. they said its probably the torque converter but after reading multiple forums I am not so sure now.
I have a 2010 Camry 2.5 liter with 150k miles. I have begun to notice a shudder around 30-45 mph during normal acceleration. It does not happen during a hard acceleration. As I watch the rpm's when the car shifts the shudder happens after the rpm's drop when the car is engaging in the next gear. After some research I'm led to believe I have a failing torque converter. If it is the torque converter can just the converter itself be replaced or does the whole transmission need to be replaced.
View 11 RepliesAbout 6 months ago I bought a '08 GS 350 CPO. Love the car but after a month or two of ownership, on light acceleration 3rd and 4th gears will shudder. The whole car will buck and shake, but if I give it more gas it will smooth out. Doesn't seem to be the engine, I suspect more the transmission. Of course I took it in and they "could not reproduce the problem"... Is this just a normal characteristic of the car?
View 14 RepliesSo I was given a 1999 f150 4.6. The transmission was supposedly either new or rebuilt. (I'm going with rebuilt) Driving it for the first time today, I noticed it had very little poor acceleration. When I would get on the gas (to the floor) the rpms would shoot up (3-3.5) but the truck didn't accelerate accordingly. It feels like the power it's getting to the wheels. Driving at highway speed trying to maintain a speed at over 70 the truck wanted to stay at 2500 rpms but if I let off the gas just a touch it would shift up (into overdrive I think) and level out at just below 2000 rpms, but if I accelerated even just barely, it would down shift and go back to 2500. I've also noticed the truck runs 5 mph faster than it reads with stock sized tires. I've check the tans fluid and it is bright red in color and at the appropriate level. I crawled under the truck and noticed the trasfer case mount was wet with fluid (not dripping) and the rear output shaft of the transfer case was also wet. Could this be a transfer case problem?
View 13 RepliesMy 1997 250hd has the 5.8 we have rep[laced the cap,rotor,iac,tps,plugs and wires about to do the fuel filter and drop one of the tanks and change out the pump,also has a new fuel regulator. What could be making it choke out under acceleration...
View 3 RepliesI and a friend both have 1997 ford F250 Diesel pickups and both at about 140,000 miles have had problems with the transmission going out of overdrive and changing gears at higher than usual rpms. The overdrive light blinks and if the pickup has a day or two it will reset the computer and function normally. Any fix easier than a new transmission???
View 5 RepliesI have a shudder that happens when turning right at a grade of about 10% while accelerating, and only on that condition. While making a routine drive somewhere, there's a turn with that one condition. Every time it shudders. It doesn't bother me because it happens so rarely...
View 6 RepliesMy 1997 F250 Heavy duty shifts very hard and sometimes feel like it slips out of gear (i press the gas pedal to the floor and speedometer rises very slow and truck doesn't move like it should.
View 14 Replies I finally upgraded from my 1998 F150 5.4 to a 2008 F150 Lariat supercrew 4x4 5.4 3v with 83k miles. I've had the truck about a week and have already noticed an issue. During light to moderate acceleration, I notice a slight hiccup in the 30-40 mph range. This "hiccup" is best described as a quarter second dead spot in the throttle. At times, I have noticed an additional hiccup between 20-30 mph that does the same thing. Occasionally, I will also feel a slight vibration on take off. It's important to note that if I accelerate at a quicker pace or really get on it, I can't feel the issue. I have also had a tough time replicating the issue when I deactivated overdrive. Not to say it wouldn't do it, but I really couldn't tell if it was doing it. Also, I've noticed that when I really get on it, It takes maybe a second to catch before accelerating. (From what I've read, that's common for 5.4s though, just thought I'd note it)
I have had spark plug and coil pack issues out of my 1998 model, but they felt different than what this truck is doing. Is it possible that this is the same issue but is manifesting itself differently? I briefly spoke with my mechanic and he seems to think it sounds like a torque converter issue. He checked for codes and none were showing or pending in the computer. Transmission shifts good. Fluid is a pinkish orange color, and there are no metal shavings on the oil dipstick. I started to notice the truck would sometimes shift a little hard into 4th. I took the truck by my mechanic and he rode with me. I was able to replicate the original issue. He told me it felt like something in the transmission. He said that my fluid smelled a little burned to him, but it was still a pinkish orange color. He said he would service the transmission and adjust the bands. The truck has 83k miles so I'm not too worried about a major transmission problem. He said he was fairly certain the servicing would correct the issue. I'm also going to have him put a new set of coils and plugs on as well. Am I missing anything?
Just rejoined this Ford gang after years absence. Used to own "The Muny Pit", a '79 F-150 4WD monster with a '69 429... constantly breaking something. Anyway, where to look on my '08 F-150 XLT 4WD with a 5.4, 83,000 miles. Searched the search bar for my title and found a post on an '00 Expedition describing similar issue than mine... for about 6 months now when I accelerate either from stop or a crawl; forward or reverse; more so when turning, but does do it wheels straight.
Upon initial acceleration I have this horrendous rumble / shudder in the truck, like the grinding metal bearing sound/feeling felt when the pinion bearing went out on my '79 (only felt it seconds before the 9" rear pumpkin exploded). Once rolling it stops. I have checked all wheel bearings.. I have check all the suspension joints... everything looks fine, no obvious issues. The only suspension mod I've done is a 1.5" leveling kit when brand new. On the Expedition two replys suggested changing the transmission/transfer case fluids claiming it cured their vehicles.
Was driving to Airport yesterday and out of nowhere got the flashing check engine and shudder/limp mode while trying to merge/accelerate onto the onramp (had to gun it to go around someone who decided to stop on the onramp for no reason). Let off the gas and the blinking went away. Upon leaving the airport I was accelerating again at highway speed to pass and got the blinking light and then a solid CEL. Found my way to a Autozone and got the code read. P0301 Cylinder#1 Misfire. Was suggested to change COP and plug.
Changed COP on the spot and had to drive it home to my tools to install plug. Thought maybe that since the CEL was still on solid after changing that the code needed to be cleared for the PCM to function normally again. Still have shudder when accelerating hard, so thought it might have been injectors so got cleaning service done at Goodyear. Still have the issue. Disconnected battery and performed IDLE relearn just now and it still is shuddering upon hard acceleration. Stumbled across TSB 12-6-4 which speaks to my symptoms.......I do not have the plate which in turn would imply I do not have the PCM update it references.
I have not noticed a misfire nor had an acceleration issue before so this was a surprise to come out of nowhere. I'm going to be calling my dealership in the morning.
I picked up a 2004 F150 a few weeks ago. It has the limited slip 3.73 rear end. During acceleration on turning, I'm feeling quite a bit of chatter out of the rear end. I've read the TSB on it, and I'm wondering how much it'll cost to get the clutchpacks replaced in the rear differential.
View 14 RepliesI now have an '01 Mountaineer with AWD and the 5.0. I have a strange vibration that only seems to happen when I accelerate as I get on the highway. I get up to speed and just as I let off on the throttle I get a vibration/shudder from the rear. Almost as if I ran over the rumble strip on the side of the highway. It's a short grrrr, then it goes away.
View 2 RepliesI bought my f 350 new from the dealer and have had many of the problems associated with this truck. Now I have a severe shudder while under acceleration when i either let off the gas or increase speed the shudder goes away. My dealer thinks it is injectors but I have little faith. Shudder seems to be rpm consistent and seems to be in the front end. oh yea it idles great and runs great except at that specific range.
View 4 RepliesI have had my ecoboost for a couple months now. Overall I am very happy with it but I have noticed a shudder recently when accelerating and when coming to a complete stop at times. I only feel it when accelerating from a stop or when stopping completely. Kind of feels like something slips. I think I recall reading about this before on the 2011 and 2012s somewhere. What is causing this and is there a fix or is it just the way these trucks are?? I can deal with it but it is kind of annoying when driving in traffic.
View 1 RepliesI just bought a 2006 F150 with the 5.4 triton motor. Under acceleration at around 40-45, the vehicle starts to skip and shudder.
Based on what I read online and the fact that I pulled a code for a #1 cyl misfire, I assumed that i just need to change the plugs, and I am trying to scheduule that now.
I just read another post about the TC not locking up due to needing the filter and fluid changed and a way to fix that would be to take OD off and see if it still does it.
When I drive with the od off, it does not do it but i am now confused since i got the one code for a misfire.
I have a 1997 F250 that I am fixing up. The issue is this... The dash lights now flicker off when I place the transmission in Drive position. I can slightly move the slack in the gear selector and the lights come back on. When the transmission is in Park, the dash lights work correctly. Not sure why there is some type of switch to control the dash lights buried within the steering column?
View 2 RepliesI just bought my 2015 F350 long bed Platinum a month ago, and the first trip with my 12,000 lb. 5th wheel had a vibration when starting out, but only from a stoplight with some acceleration or an incline, not at level slow startup.
View 6 RepliesI am having a minor problem with my 05 F150 Lariat. Under light acceleration going up a slight grade the truck sometimes shudders (vibrates?). If I let off the gas or accelerate slightly it stops. At first I thought it was a feedback loop with the electronic throttle so I had the dealer reflash the computer but that didn't fix it. I've noticed that it happens right about the time the torque converter locks (looking at the tach) and I'm sure it has something to do with torque converter locking up and then disengaging continuously. Funny thing, it seems to happen frequently on the same hill at the same speed. What was done to fix it?
