Ford F-150 (2004-2008) :: Trans Bangs Between Two Gears If Slightly Accelerate
May 18, 2014
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.

2006 F150 FX4 5.4L, 118k miles... At highway speeds (45-50) and (55-60) as I am slightly accelerating it feels like the transmission or maybe ignition system is skipping a beat. Kind of feels like a small bump. I replaced spark plugs with motocraft about 35K miles ago and recently all transmission fluid via cooler line. Had some concerns about system flush so I just drained and refilled entire system via cooler lines. I have read that it could be my COP's ...

Question regarding the car failing to accelerate properly that only happens just when I start driving it.
Turn on the car and go, it accelerates fine in first gear. When I switch to second gear it starts shuddering at 20mph and won't go any faster no matter how hard I push the pedal. I switchh to 3rd and its fine until I get to 30mph and then the same thing. I pull over, turn off the car, restart and it's all fine.
I drive a 2004 volkswagen polo 1.2L engine with 100,000 miles or 160k kilometres.

I have a 2007 an at about 52mph the truck has a slight but irritating bounce (up an down) an after a while sickening. It maybe felt it was coming from the rear. So I had the rear tires balanced an the guy said my right rear tire had a bend to it. Well assuming that the balancing fixed the problem it did not. So I'm going to put on the spare to see if it still bounces what else should I do?

Recently when I leave my driveway which only has a slight grade to it my truck makes a clunking sound when I hit the gutter and while turning slightly. Also my front drive line from transfer case to front axle has some play in it. I can rotate the front drive line about 3/4" to an 1" while parked in the driveway. Changing u joints. I figured this would be a good starting point. 2005 XLT 4x4 5.4L F150.

I bought a '05 F-150 with a 5.4 with 112k miles on it a few months ago. It had been sold from an auction, looked really clean, and a good price. Not long afterward it started having issues with running rough at idle. That's when I found this forum and began reading. Tried different things but it only got worse and finally had a shop look at it. Cam phasers were not doing well. Not a cheap fix but more involved engine work than I had ever done so I had them do the work.
It ran fine for a few days and then the idle rumble came back slightly and the check engine light (CEL) came on. I read the code and it came back with a number that indicated air flow was an issue. Internet search said to clean the throttle body. Some threads on this site also said do the Mass Air Flow (MAF) sensor while I was at it. Much has changed since I used to work on cars as a kid. Everything has it own cleaner. I cleaned the MAF sensor with MAF cleaner. Cleaned the throttle body with throttle body cleaner (it was beyond filthy) and a toothbrush. Put it all back together (started late and it was dark by now) and took it for a quick run to see how it had improved. Instead of smooth, it started running even rougher, and within 100 yards went into fail safe mode. Now my mood is getting darker. Park it and go inside to watch the Aggies in their bowl game.
Good game but the truck is still running rough and I am losing confidence in my ability to do simpler things on it. I get up the next day and run codes on it. It had three codes all pertaining to air flow or the throttle position. I am thinking I screwed up the throttle setting somehow when cleaning or maybe only put the MAF sensor in upside down (that seemed unlikely since the screws only seemed to line up in one orientation). So I open the hood to check the MAF sensor just in case and find to my embarrassment that, in the dark, I failed to plug the MAF sensor back in. The problem was a loose screw holding the tools. I plug the sensor cable onto the sensor and take it for a ride. It runs great. Life is good. MPG is climbing higher on the onboard display. My confidence is returning even after humbling mistakes. After everything, I still love this truck.
So, now for the tune-up advice. The truck runs well but still rumbles slightly. Based upon everything, I believe it was well cleaned before it sold but maybe not fully serviced. Spark plugs were possibly never done. I intend to do a tune-up on it but do not know what has already been done so I'll assume almost nothing. The air filter looks brand new. The serpentine belt has nicks so that will be on the list. I am thinking of changing the following:
Spark plugs
Spark plug boots
fuel filter
serpentine belt
PCV valve
Oil was changed when the cam phaser work was done. So the advice really boils down to a question:
Is there anything else I should consider changing or doing or cleaning? I have not worked on cars much in the last 30 years but am beginning to enjoy it again.

Ok, I have a 2006 Ford f-150 5.4L engine. it has 88000 miles on it. Here recently it has started acting up on me. It starts shaking violently when I slightly accelerate going up hills at any speed. On level ground it doesn't do it. Going down hill it doesn't do it. When stopped it doesn't idle rough.
It does this shaking when I barely press the gas. When it starts I either let off the gas or I push the gas to the floor and it stops. What is going on? This is the first Ford I have ever known. I don't know anything about these vehicles. I have read it might be the coils and plugs but then people have told me it might be the torque converter.

I noticed a slightly rough ride around 70-80 mph sometimes on interstate a month back but thought it was my scalloped tires that need replacing and ignored it. Last weekend i had to go to MI from GA pulling a small enclosed tandem axle trailer (6x12). I started after work and made it to VA before stopping for the night with no problems not even at 70-80. Fueled up first thing in the morning (BP Fuel) and headed farther into the mountains when the truck started shaking when it should be downshifting (into overdrive I am guessing?)
No check engine light come on so i pulled off the road checked rear end and motor oil everything was fine, topped off tranny which was slightly low but was on dipstick .I let the truck cool for 20 min then got back going again. I continued driving with overdrive off, and not on the truck. Every time it had to downshift under hill climb it would start shaking but i would let out of the gas and it would stop. Once i got out of the mountains it was fine and couldnt tell it was running bad at low rpms, and also drove fine when i got off the interstate for fuel driving in towns.
I drove that whole day through ohio mich and back trough ohio when entering kentucky. It started to downshift and run at high rpms with no problem, and started acting up when i got back into the mountains.When the truck would go to downshift it started to shake uncontrollably again. then is when the check engine light come on and flashed. I babied in until tenn when i stopped at oriellys to hook up to scanner. scanner read misfire on 5 and ignition coil d primary secondary circuit malfunction. I checked the #5 plug (fine) and replaced the #4 coil, and didn't check the #4 plug.
t kept going and it never fixed the problem. stopped and jumped my coils around and check a few more plugs which all were fine but never that #4 (why idk), after being fed up, sat night, no mechanics around and wanting to get home i drove it the rest of the way. it never idled rough until i got almost home in Ga. When i got home the next day i pulled all plugs and all looked brand new still except the #4 which had the whole prong and tip completely burnt off. I replaced it and nothing changed, but my exhaust sounded restricted. Brought to a shop and it is now reading a misfire on 4 (with brand new plug) 5 7 and 8 and also saying it is running lean. They changed fuel filter and plugs but nothing still.

When driving my 2006 F150 it drives real smooth until I hit 50, then it feels like I'm driving on a slightly bumpy road, once I hit 55, smooths out again. Only drives strange at 50 mph. Other speeds smooth as glass.

Yesterday afternoon after warming up (car still in park) the engine shut down was very rough. I heard a quick string of maybe 5 or 8 loud bangs under the hood. Sounds like something got loose and banging inside the engine compartment and ready to fall off at any moment. This morning it was just a bit rough but not nearly as scary. Other than that the car seems to work fine.

Well I have a weird thing going on with the anti lock brakes. Its normally more noticeable when its cold. Coming to a slow stop you can feel the anti lock brakes pulsing slightly or more noticeably if you hit a bump braking at slow speed. The only mods to the truck are 285/70/17 inch tires and a leveling kit. Not sure whats going on with it, but i thought i should check here before getting my wallet lightened by the dealership.

Here is the case. I drive a 150 mile trip once a week, mostly 60-65 mph highway. Well in the last 3 months it started randomly bogging down slightly with the cruise on. I can be going along and its like a strong gust of wind hits the truck from the front. It will make the engine bog then it like releases or frees up and the truck carries on.
I also noted on my edge evo (not programmed just plugged in for the gauges) that it shows the engine load shoot from about 30% cruising to about 80% when it have its issue then on the sort of POP release the load goes back down to the normal range. The entire bog down only lasts about 3-5 seconds and I can power out of it by pressing the gas. It may happen 15 times on the trip may only happen once or twice...very random...
Things I have tried
Replaced plugs and COPS
Replaced FPDM
Cleaned MAF and TB
Replaced Air Filter
Changed Oil
Fuel Filter changed in November

I have a 2006 F-150 5.4L 4x4 Lariat. I was wondering where or how I could find out what gears are in my axles.

It has been a long time since I have owned a Ford truck and recently got a good deal on a 2004 Reg. Cab 4x4 (4.6L). It only has 58K miles and still looks, drives and smells like new. I have just noticed that the Rear end gears whine very loudly at 45 mph. It is quite everywhere else accept a little hum at 60mph. No other issues with the truck and perhaps, this is just normal on these newer fords.

I just bought a 08 Screw with the 5.4 3 valve, 4x4 with the 373 gears, and 25,000 miles on it. I love the truck, but what is the best that you have gotten for mileage on your trucks with the 373 gears? Does it do better at 75 mph or 55? I haven't checked mine yet so I am wondering what to expect...

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.

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.

Today I was driving on the interstate at about 70 mph and my truck seemed like it popped out of gear...no loud noise or anything. I was able to coast off the off ramp and my truck was still running but sounded a little odd when I revved it. No gears work and when i revved it in gear it sounded like something loose in the bell housing area maybe. After I turned it off I was not able to restart it, sounded like the starter was just free spinning. Flywheel maybe?

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.
