Ford F-150 (2004-2008) :: Trans Shuddering While In OD
Mar 18, 2015
2008 5.4L ...I started a thread before concerning my tranny shuddering while in OD. It did it before and after a tranny rebuild. That's when I learned of the common problem of a bad coil pack not allowing trans to lock out into OD. Yesterday I took the truck to a shop to have it scanned. I was hoping to find out which cylinder is the problem. No fault codes were found. Now the mechanic thinks its the tranny, and the tranny guy(who has had the truck twice) says its a coil pack. I can change it if I can figure out which one it is. Do I have anymore options left to find the bad coil pack, or am I left with changing them all.

My boss drives an '08 F-150 with a 5.4. The other week he had a horrid shuddering issue, misfire, and some known transmission issues so he took it to a shop. Supposedly the heads were pulled, heli-coiled, #7 coil was replaced, new plugs, trans rebuilt...a whole laundry list of stuff was done. He comes to me with complaints of a shudder in OD in low RPM primarily and a flashing check engine light with a #7 misfire code. I popped the hood to find no coil had been replaced (mechanics around here are REAL sketchy) so I told him to change up a new coil and I would throw it on to see if that fixes the issue.
Other than that, smooth idle and decent power with no shuddering except once in a while just coming into OD in low RPM...so around 40~ish and not throttling it hard. If he gets into it and blasts through the gears it has no shudder. I said the miss could be the whole issue, starting with the plugs and known misfire coil (#7) would be a good place to start.
A quick inspection in ~10 degree snow showed me the heads do not look like they were removed. The mechanic steam cleaned the engine, so looking for smudgy prints won't work. I know on older Fords the head gaskets stick out a little past the heads...do they on these too? He is questioning if the engine was even touched, and rightfully so in my opinion. Pulling the plugs would be the next step, but I need heat and tools for that.

E brakes were sticking so I took off wheels, rotors, calipers, and cleaned the E Brake caliper and lubed it. Started driving and E brakes are still sticking? What gives? Could the cable be hung up? Wonder if I should replace the E brake cables.

Over the past few months I've noticed that my truck has a very intermittent shudder under mild acceleration. If I accelerated more during the shudder it seemed to disappear until I let off the peddle a little. When it happens the truck doesn't seem to be lacking power and the engine throws no codes. It happened again today right as I had stopped at a red light. I noticed that it was shuddering at idle too. I shut the truck off at the intersection and the shudder was gone once restarted. What it may be?

I have a 2005 f150 4x4 with a 5.4 it was studdering on the highway under light load, i changed the plugs and coils it worked great for a day now working worse and giving a misfire #7, so i swapped the injectors around still misfire #7.

2006 F150, 4.6 V8 ... My truck was running fine until one morning I was sitting in the truck giving it my customary 30 second morning warm-up and it starting running very rough and quickly threw Check Engine LED.
I hooked up my laptop and got the following error codes: (To assist with future searches, the error codes are P0302, P0303, and P0353)
It seemed to drive fairly well, but low RPM torque causes major shuddering, so I try to keep the revs up to avoid damaging other components. The first step was to replace the spark plugs. They looked to be original and I'm at 140K on the truck, so it's probably time.
I went with Bosch Platinum as the factory plugs were platinum. When replacing the plugs, I moved the coil pack from cylinder 2 to cylinder 3 to determine if the problem would move. After the plug swap, the engine did run noticeably smoother (so the plugs worked overall), but still had the low rpm shudders and the same error codes (after clearing them).
Unfortunately, the error codes still indicate cylinder 2. I guess a misfire could be related to the fuel injector as well, not firing at the right time or not a complete spray, but what else could cause this?

My new to me 04 4.6 shuddered and misfired really bad last week, got couple misfire codes. I changed plugs which were really bad, like burnt out to .080, got a HEI ignition tester and got a healthy spark from all the coil packs. Drove it today and ran much better but still would shudder under acceleration when cold, wasn't as bad when warmed up but still noticeable. I thought if I got a spark with the tester that means the coil is ok? or is that not the last word in coil health. Or should I look somewhere else like injectors ? Haven't got any codes since plug change.

I have a new to me 2005 F150 SuperCab Lariat 4x4 with 155,000 miles on it. About a week ago I replaced the from passenger hub assembly and half shaft (torn boot). When doing that, I noticed that the IWE actuator was not working right (would not compress evenly). When taking that off, there was a bunch of rust that came out of the vacuum line ports. It started moving freely after cleaning all of that out that I could (I will be replacing it soon). I assembled everything back together and all seemed OK mechanically.
I also scanned the truck and saw the code for a bad IWE solenoid so that is being replaced tonight. I also have not checked the drivers side yet.
So...now that I have done all of that, the truck started occasionally bucking/shuddering when I slow down from highway speed to about 30mph and lightly accelerate again. It does not do it every time though. There is no grinding/whining noises either. Could this be caused by the IWE system somehow? Maybe slowing losing vacuum and having one engage and the other disengaged?

I have a 2006 F150 4x4 5.4. For a long time it idled poorly and would take 2 trys to start. Today it started shuddering and the engine light came on. The engine light went off but it still runs rough and smells of gas from the exhaust. It is not very drivable and I can't afford to take it in. I have lots of mechanical experience but not with this electronic junk and need diagnosing the problem. I have a code tester and this is what it said.

I bought a 2004 heritage V6 Transmission was bad my father in law rebuilt it (he is a retired Ford Transmission guy) in drive it will not shift out of low if you take off in 2nd it will shift out of low on a rare occasion the OD light on the shifter will start blinking and it will shift fine?

Feels like my transmission is slipping from 40m/hr to 65m/hr. But only when I am at a constant speed and not when i am accelerating. only happens when I am at approximately 1400rpms and while in overdrive. Does not happen in any other gear just overdrive.

I am finally getting around to changing the trans fluid on my 05 f150 5.4 4wd xlt auto, what is the torque value for the trans pan bolts.

I have a 2004 f150 4x4 with a 5.4. i have been leaking some fluid for a few months now but when i check oil and transmission both fluid levels are fine. I crawled under and it looks like something is leaking near engine and trans meeting and fluid looks reddish making me think its trans. now this week I developed a whining sound when truck moves. Again I rechecked oil and trans fluid levels and are all good. i was going to check transfer case but it is way behind leak and dry.

So my truck is making a kind of a clunk noise in the trans area does it between 30-50mph does it more often when cruise control is on but still does it from time to time when it's off. What it could be?

In the "Old days" I could pull the one-and-only coil wire and trigger the starter motor to rotate the converter so the plug was at the bottom. How do ya do this with COP engines so the engine does not start?

Here's my transmission problem. 2007 f150 crew lariat 4x4 with a 5.4
When my driving conditions force me to cruise at the 28-30 MPH range my transmission often hunts for an upshift, like a slipping gear hunt then it hits in firm. It must be from 2nd to 3rd gear I'm thinking. It doesn't occur at all if i am accelerating through this gear or past this shift point. under normal acceleration through and past this speed or shift point it is as smooth as can be.
I often drive some flat but winding dirt roads out in a forest area near my deer camp and it seems this is where I settle into a speed of 28-30 mph for several miles at a time. This is where it happens, the transmission seems to begin to shift but seems to slip or hunt for that next gear then it hits in fairly firmly.
Truck has 83k on it....

My 06 f150 v6 auto died on the way to work last night. It said trans fault on the dash. The trans has been shifting fine no slipping no hard shifts. The trans has 113k I replaced the motor and it has 57k. Both have been working great until last night. I plugged my scanner up it had a bunch of codes so I cleared them and done a koeo test and got 10 codes.

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.

My 2007 F150 XLT, 5.4L, 4X4: 3 times in the past 4 months while towing a small trailer a message comes on in the dash display "trans fault" and the OD OFF flashes on the dash. What is the fix?

I picked up my 2005 F150 4x4 last winter. It has 135k miles & a slight tranny problem.
When cruising around 45 mph - right between where it wants to be in top gear or not - if I slightly accelerate the trans BANGS between the two gears.
I mean repeatedly bangs - it is not a smooth shift where it can't decide which gear to use - it is a hard BANG where it can't decide which gear to be in.
What gives? I can usually stop it if I turn on the towing button - shutting off high gear.

My 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.
