Ford Super Duty (1999-2016) :: Clunk When Shifted Into 3rd Gear If Accelerating Hard
Jan 17, 2017
Ok so I'm having a problem that seems to have been getting worse. 1999 7.3, auto, 4 door, long bed, 6" lift. When I got the truck a while back I had a slight problem where if I was accelerating hard I would hear a clunk when it shifted into 3rd gear. I'm not hard on the truck that often so it took me a while to realize that the noise was the driveshaft hitting the floorboard right at the joint at the transfer case output.
The carrier bearing was flopping around a bit so I replaced that first. No better... kept driving the truck since it was only a problem while being really hard on it. But it's gotten worse so now when I tow (usually not more than 7-8k lbs) I have a bad vibration on takeoff at low speed. If I try to take off from a stop very hard with any load the driveshaft jumps into the floorboard. So I just replaced the transmission mount and checked the motor mounts, no better. Only thing I can figure at this point is axle wrap...?

I have a 2006 F250 Lariat super Duty / 6.0 L engine / 143000+ miles / once started and transmission shifted into drive it takes 5 seconds or more for it to engage hard or if I build up the RMS then it jumps into gear hard, after it gets going it feels like I am driving on a washboard until it get warmed up good 10 mile or so. Is it the transmission filter and if so which one, I understand there is a small one on the outside of the transmission if so where? I can't find it.

So my '99 F350 4x4 is making a clunking sound and there is a distinct jolt in the truck while this is occurring.
Symptoms: From a stop while accelerating, there is a distinct jolt and clunk. The best way I can describe the feeling is like something isn't tightened down all the way so there is a split second while inertia is generated and the "looseness" catches up to the acceleration.
When stopping, the clunk and jolt is generated when the truck comes to a complete stop. When the truck rebounds backwards a bit because of the suspension pulls it backwards after stopping, you will hear the clunk again.
I replaced the ball joints a week ago an a wheel hub bearing on the right side. I don't recall this before these repairs, but it may have been making this noise. I was more focused on the grinding from the wheel bearing so I may not have noticed the clunk and jolt then.
Where I should start looking for the problem?

2012 f250 SC xl 6.2 - Is it normal to hear a single clunk sound on occasion when accelerating from a stop sign? Doesn't happen all the time mind you and I don't ever remember hearing it in the past.
Now just today, while backing up my driveway, as soon as I started the reverse motion, I heard the same clunk. Sounds like metal to metal and comes from the rear of the truck.
Only 7000 miles on her and I treat her like a baby...anything I should be concerned with?

I have an issue with my 6.0 that no one can figure out. It has been happening for about 3 years. After accelerating hard, motor will rev out like it just popped out of gear. It is still in drive and the edge cts says 4th gear usually. I have to let off the pedal and coast a bit and everything "sync's" up again and works fine. It can happen from a hard launch from a light or get on the freeway. I recently put an ATS transmission in because I figured solenoids were beginning to fail. Still does it. I am running innovative tunes with sct tuner. It had a Suncoast billet flex plate and ATS 5 star converter. I run Amsoil fluid, it is clean, red, and at the proper level. Truck has almost 80k miles. Also 37" tires and 4.88 gears. It has not done it while towing our 35' toyhauler, but I am easy on the pedal when I tow. I recently checked the transfer case and changed fluid to Amsoil. The old fluid looked good.

Was pulling passat home 50 miles round trip this saturday and downshifted into 3rd. As the gear engaged it let out a loud clunk locking into 3rd gear. was able to find neutral after a day but slammed into gear just idling. Can find neutral on pattern but not actually get there....also drags right rear tire upon disengaging clutch.

Brand new to diesels with an 02 F250, 7.3 auto, 149k, 4R100. I have been hearing a whine (not the turbo...) for the last few days and after searching the web I'm freaked out about transmission issues. The whine is mostly present in gear while accelerating, I can slightly hear it in park/neutral as well. The sound is a little higher pitched than a power steering pump, pitch rises with acceleration but doesn't FALL as fast as the RPM with shifts, it lags for just a second then drops and starts the climb again with the next gear (i feel like this is indicative of something?). Runs fine and drives like what I would think is normal, only leak i see looks to be from valve covers making its way to everything. Transmission fluid looks great on the dipstick.

New truck 11000kms ago thats done medium amount of work but nothing heavy or sustained for long periods of time. I get the feeling of clutches slipping especially when truck is cold but also when normal temps. Doesnt make any weird noises or anything. I can really notice the difference in torque if in manual mode being much better, but still not perfect if i stomp on the gas pedal and go through the gears in manual mode will still slip. Also is really harsh shift if i come to a halt in 3rd manual mode with the brake pedal depressed push minus button the truck makes very loud clunk noise into gear 2 then 1. Took it to ford they couldnt find anything ? Thinking of trying another dealer.

2003 F250. 6 speed. 5.4 2v. 4x4. 165,000 miles
When purchased, there was a vacuum leak and truck ran like crap and PO drove it that way for a while. I fixed the vacuum leak, discovered a miss between 1,500 and 2,000 rpms in every gear while accelerating. No miss at idle.
The truck has:
- no CEL
- new Motorcraft spark plugs that were not dropped, bumped, or over torqued.
- new fuel filter
- new air filter
- new alternator
*The miss usually does NOT happen in the morning on the way to work after sitting 14 hours.
*The miss almost always goes away after the truck gets up to operating temp.
*The miss ALWAYS is present after work on the way home after sitting 9 hours.
Fuel pressure?
Bad COP?
Fuel Injector?
Something totally different?

I recently purchased a 00 F250 psd 4x4. Other than doing all of the fixes it needs to make it ride better I have been questioning the trucks "get up and go" and the EXTREMELY sensitive skinny pedal. Truck seems to pull very hard and puts out some black smoke under hard throttle but nothing like the really tuned trucks I have seen. But the skinny is so sensitive its hard to drive under 40mph in 3rd and once it gets up to 55 or so its real sharp getting on and off the throttle. Trans shifts great, TC locks and unlocks, truck runs awesome IMO but just a bit harsh. Is there a way to find out if it was tuned prior to me buying it other than inspecting for a chip, or is this the way they are and I just have to get used to it more...?

Got an '01 f350 v10, auto. When using steering column shifter tends to be hard to find reverse and drive. Is it something in steering column selector or is it in tranny? The truck has 40,000 miles on it. Have a parts truck also so just trying to figure out where to start first.

I have a 1997 F250 heavy duty 4x4 7.5 efi. I just bought a 2003 weekend worrior weighing 5800lbs dry. When I go up slight hills in 4th gear it seems to work real hard especially on freeways, could my clutch be slipping or am I just at max tow

I started having a issue with getting my 00 f250 power stroke to start. It started out I could move around the gear shifter in park and get it start and today I had several times I had to put it in neutral to get it to crank. I did notice that my shifter on the column seemed to have some play when in gear but then again my 99 F250 V10 also has some free movement when in gear. Is there a neutral safety switch I could replace or any way to adjust the shifter?

So, in my 99 Bounder RV (F53 chassis), V10
I think it has a 4R100 transmission in it (I have not verified this).
I had the oil and filter changed about 10K ago.
Runs and shifts fine .... then I stop and idle with it in gear (say stopped in traffic for a few minutes).
Now the thing shifts super hard! I actually get rubber in all gears.
So I pull over, shut it off. Restart the unit and everything is fine again.
It does this very consistently!
I went to the local transmission shop. They said with 110K in an RV it could be anything and I should think about letting them rebuild it.
Now that is something I would do ... not diagnose a problem and just rebuild it. I thought a "professional" would actually look for the problem first.
I don't want to rebuild the transmission if there is small item that will fix this.

I'm looking at purchasing a 2003 F-350 from a Ford Dealer, Drove the Vehicle last night and the Gear shiftier was very tight and hard to pull down. Is this a real concern? The Sales guys said its better to be stiff rather than sloppy. But they will say anything, right. The vehicle is a deal and so I'm looking to find out why.

I go out of town for work for a week and come back and my 1999 F250 V10 GAS, is acting up. It started when i tried to drive it and it didn't want to shift, it would rev up to 3000+ RPMs and finally shift really hard into gear along with the speed odo not keeping up and bouncing around not wanting to work. I also had my entire gauge cluster lit up with no key and door closed. all the lights were on and it was "dinging" like the door was open and it wasn't. you would hear it when you put your ear up to the door.
So my first thought was to change the VSS (which I did) no luck. So I started wiggling wire loops under the fuse box in the cab and the "dinging" quit.. i took it for a drive and it works like nothing ever happened. Obviously I am guessing there's a short so i brought it to my mechanic and hes saying he couldn't find anything by the fuse box but he thinks its closer or even attached to the gauge cluster itself. could this be true? Why would the gauge cluster loop throw off the shift points?

One of our trucks, 2004 F350 Powerstroke, my company truck, recently the last snow even we had, my tow haul mode would pop on and off almost evertime I shifted from drive to reverse while plowing. I didn't want it on, it just kept poping on and off. Thought maybe the button was stuck, but it moved like normal. My other thought was there is a loose connection in the shifter or column causing it to go on and off.

06 F550 w/5r110w. Truck and trans runs great then trans acts like it was shifted into neutral, rpm's flare up and if you don't get your foot out of it the trans will re engage aggressively. Changed the speed sensor on the rear axle, there are no codes, had a trans shop change the filters and fluids then change out all of the solenoids. They tell me its not a trans problem.

So the other day i opened the door and heard a super loud clunk noise come from the door and when I turned the car on and pulled hte window down it wouldn't go down all the way, only about 75% of the way so I assumed like BMW cars the window motor died but oddly it continued to go up and down just now 100% down.
Then 3 days later when I came to drive the car again the window went down to the 75% mark and now its jammed there with no movement even if I tried to lift the window up myself. Usually a broken motor allows this to happen but since it isn't budging I am wondering if its an electrical issue with the power window button more than the motor?
I say this because when i try to lower the passenger window from the driver side it works than out of no where on the 3rd time it wont move at all than 5 minutes later it will move or if it doesn't move I just go and pull the window down from the passenger side then I come to the driver side and try it and it works again than it'll stop again. So maybe its the power window control buttons on the drivers side that's failing?

2009 F350 4x4 DRW. Just replaced rod ends, drag link, sway bar bushings and end links, ball joints, and shocks. I have a clunk when the axle travels downward on bumps. The only thing I see is that the tie rod assembly will rotate easily by hand and I can make it clunk when I rotate it. It does not rotate in the ends, the ends rotate with it. Thinking this may be flopping around over a bump. Does tie rod rotate easily?
