06 with 5.4 and AT. It shudders in overdrive during light to no acceleration. I was told it was the converter. I was also told by a technician in a trans shop that the Trans-X additive for hypoid oil in a posi-trac was ok to use even though the back of the tube says "Not safe for automatic transmissions". Do this is accurate or if the guy was just blowing smoke?
View 5 RepliesFor the last week the car has increasingly been shuddering during acceleration. The mechanic thinks its just bad gas, but I'm worried it might be the timing belt. What is the damage of inflicting engine damage if i use up the current tank before trying to find other problems? Should I completely use up the current tank, or can I fill it up now (about a third of the tank is left) thus diluting any possible bad gas?
View 5 RepliesI have a 2006 Ford Escape that's turning into a mystery. Over the last few months the warning lights have been reporting issues with the overdrive. I've taken it to the mechanic who hasn't been able to identify the issue.
He's cleared the issues from the ECU, and the car doesn't complain for about 2 weeks, then it reports a different issue related to the overdrive (eg: OD or transmission).
Possibly related, the car occasionally loses power on acceleration. When taking off from a stop, it'll be really underpowered while getting up to speed. This only happens occasionally.
Is it a part failure, or could it be electrical or related to the sensors?
I have a 2006 F150 5.4L 3V with 105,000 miles on it. Recently, it has developed a misfire that is progressively getting worse. It happens when the truck is in overdrive, with engine RPM between about 1200 to 1800. Cruising at this RPM the truck runs great. If I increase the throttle, I develop a pronounced misfire. Once the truck down shifts out of OD and engine RPM exceeds 2000 RPM the misfire goes away. I have never had the CEL light come on during any of these events. The truck has the original plugs in it AFIK. I have not changed them.
View 6 RepliesI have an 06 Lincoln MK LT with 147K miles. Just recently when it went into overdrive it was like I shifted into neutral. Pushed the overdrive off button and it drove just fine although no 3rd gear (overdrive). what do I need to do here other than paying for new tranny.
View 2 RepliesI have a 2004 Fx4 that I took on a cross country trip this past weekend. Everything was running fine until I stopped for the night and got a hotel. Woke up the next morning and the "O/D Off" light was illuminated on the dash and the overdrive toggle button (on mine, on the center console next to the console mounted shifter) doesn't work to turn overdrive back on. When I got on the highway it wouldn't upshift into overdrive.
Hopefully this is just the switch assembly (?) so I won't have to do any major tranny work . . . However, I found it weird that if the switch failed it didn't fail in overdrive since I was running in overdrive the day before.
Also, any link to a good thread about removing the trim on the center console in those trucks to get to the switch assembly? I assume that's a pretty easy job but I've never dug into the console before.
On my 2006 Ford F150 2WD, v6 automatic, the overdrive dash lamp is blinking, I get a engine light and the code I get is a P0743. That indicates the solenoid or wiring is bad, but everything works just fine. The transmission is running fine, clear fluid - no odor. The overdrive works and the truck shifts like new. When I start, the "OD-OFF" light immediately starts blinking and never changes. I can activate the OD normally and it doesn't effect the blinking light.
Where to start? I suspect that since all is functioning well, the issue is with the signal to the ecm? By the way, I can clear the code so that the engine light goes off, but the "OD-OFF" light remains blinking.
I have a 2004 f150 with an edge programmer. My transmission will only stay in 3rd gear, the overdrive light is flashing, and it is giving these dtc's: p0720, P0722, P0731, P0732, P2106.... What is going on?
View 1 Replies2003 F150, 5.4 FX4, overdrive light flashes. Took to a shop they said overheating issue, but I don't understand if it is a overheating issue why does I flash at 4 in the morning when I leave for work fter sitting all night and why does it stop when I do over 70 on the highway.
View 4 RepliesI have a 2006 F250 with the 6.0 PowerStroke and automatic transmission. I just purchased this truck at an auction about a month ago.
Today I notice the transmission is not shifting into overdrive. No warning lights. If I press the tow/haul button in no change but the tow/haul light does come on. If I press it again (to turn it off) the tow/haul light goes out but still the transmission will not shift into overdrive.
This leaves me at about 2000 RPM at 68 MPH. I just had a Ford dealer perform Transmission service last week. (20,000 miles after the last recorded service.)
I am already not happy with the service I received at the dealer so I am really hesitant to take it back to them if it is something not related to the transmission service they performed.
Long delay bringing new travel trailer home last week. Shift cable not placed properly in retainer during assembly (there is NO way it popped out) and it was resting on exhaust manifold. Evidently towing camper made enough heat to burn through the shielding and truck trans would not move out of drive.
The good news is that I could climb under (getting too old for that stuff!) and put it into gear/park by hand. But of course I didn't know that for the first 4 hours.
I have a 2006 F-150 SuperCrew King Ranch. The 4R75E automatic transmission has some sort of fault. In overdrive...intermittently...it stumbles or shudders for a second or two. By feathering the throttle...it calms down. If the overdrive is cancelled, the shifting from 1 to 3 is fine. The fluids and filter have been changed.
View 6 RepliesMy 2005 STX 4x4 was running fine until yesterday, then on my way home I lost all forward power. The odometer displayed TRANS FAULT and the O/D OFF light was blinking. Limped home.... Today I checked the fluid level and it was a little high, so I ciphoned some out. I read a lot of posts about the same problem which lead me to my local autozone to have them put a code reader on it. Unlike all of the other posts, NO codes came up.
According to the scanner, my truck is fine. I was hoping to get some kind of "P" code to target the problem, but no such luck. I checked all the fuses and they are fine. What should I do now? I don't really want to take it to the dealer, fearing that they will automatically say I need a new tranny without checking everything else first.
2006 ford f150... Mine started out as a misfire problem which I first changed the plugs. I followed the Ford TSB and got all 8 plugs out with no problems. Still misfiring and setting a code for bank 1 catalytic converter inefficiency bank 1. By the way bank 1 is passenger side. After changing bank 2 because the guy at Advance auto said bank 1 was drivers side. Still setting misfire codes and for bank 1 cat. ineff.
So after installing new coil packs and 2 injectors, Still misfiring #3 and #1 and cat. ineff. bank 1. Decided to buy my own code reader, which is a must if you are going to try to work on these new vehicles. Decided to unplug o2 sensor to see where bank 1 really was. Thats when I found out bank 1 was indeed passengers side. Changed o2 sensors. Still misfiring. Decided to buy the true bank 1 cat converter.
Dropped old bank 1 cat and found all of the internal workings all broke up and clogging converter. Truck runs like new. I spent 178.00 for bank 1 converter at pep boys. After spending O approx. 600 in other parts that didnt fix it. I think the spark plugs not being changed until 115000 miles caused the converter to go bad. Buy a code reader and it makes it a whole lot easier to diagnose your problem yourself. and save a whole lot of money throwing new parts at it.
I have a 2006 ford f 150 with a 5.4 Triton 3v engine and every time I floor it and the engine reaches 3000 rpms the truck backfires and looses power. Sometimes it wont pass 3000 rpm it just stays there and backfire and have no power. Sometimes the check engine light flashes...... I took the coils off and looked at them and they all looked pretty clean. Also the truck idles rough and sometimes when it cruising at low rpms, and I give it a little gas the truck will randomly misfire and shake hard. also the engine sounds like a diesel engine........ What might be wrong.
View 6 RepliesI need to change my plugs in my 06 5.4 122,000 miles truck is bucking and not right under acceleration but its my only transportation to work and I am afraid of breaking a plug and then having no clue what to do after that. Need input on making the plugs come out easier ...
View 6 RepliesI just bought this truck a few weeks ago and rarely hit the freeway. But 2x now when getting on the freeway it will shudder/lose power at about 60MPH. It quickly recovers and then seems perfectly fine. Both times it has happened while going to lunch and when the vehicle is not warmed up. It has not happened on the return trip. I did some searching but nothing seems to be very intermittent like my problem is. Hard acceleration is fine and I have no issues there. Its an 05 Supercrew FX4 with 39K on on it and was babied.
View 6 RepliesI have an 04 f150 with the 5.4 and recently, within the past few months, I've noticed some "jerking" especially when accelerating. At first, I thought it was the transmission, but the jerking does not coincide with the shift patterns. It jerks and stutters around 45-50 mph and 1500 rpms especially under light acceleration. Not sure if one is connected to the other, but also have no real power, I'm barely moving under heavy acceleration. ...What could I be looking at? I am thinking it has several options, I just need to know which one to explore first...cheap, meaning fuel pump/filter?? MAF?? Or Engine Coils?
View 6 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.
07 f150 4x4 shudders when starting from a stop going around corners. I was thinking of changing the diff. fluid. Is this a good start?
View 7 Replies2004 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.
