Ford F-150 - 1997-2003 :: Bucking And Jolting Like Bad Misfire / Smell Trans Fluid Being Heated Up
Apr 19, 2015
I just purchased a 2000 f150 4x4 with a 5.4 automatic... it ran great for a few days and even ran fine on the 100+mile trip home from the previous owners house. All the sudden it shut down on the highway today. I could barely get it started again and when it did start, it ran like hell, bucking and jolting, almost like a really bad misfire. I could also smell trans fluid being heated up, so I let it sit awhile and then it fired right up. It drove for about a half mile and began to act up again. I threw it in second gear to limp it home which it died several times on. Each time I'd let it sit for like 15 minutes with the negative battery cable off. It fires right up after that but the problem quickly returns. Also the overdrive button doesn't work, and the trans control switch fuse (spot 29) blows repeatedly. Also the power door locks do not work.

I have a 1997 Ford F-150 XLT 4x4 with the 4.6W and a 4R70W trans. For the past year is has been leaking trans fluid and has slowly got worse and worse. At first the truck would only leak at high speeds (when driving on the interstate for extended periods of time) and now It has gotten to the point where I am adding close to a quart of fluid a week. ( roughly about a quart every 300 miles!). I thought that it was the pan gasket leaking at first, so I flushed the trans fluid (dropped the pan and drained the TC and put on a new filter) put a new gasket on and torqued it all down and added some new Valvoline max life fluid. The first trip in the truck I noticed a puddle of fluid under the truck again.
The pan looked like it could have been a little warped, so I ordered a new pan and a new FoMoCo gasket (the one the came with the new filter was the cheap felt type). I thought I for sure had fixed the truck this time, but I drove it and once again it was still leaking. I checked all that I could before replacing the pan and gasket. I checked the trans cooler lines and fittings (no leaks) I pulled the inspection plug and it was dry (so I ruled out the front pump or TC leaking). The whole underside of the truck is covered with fluid so it is hard to pin point the leak, but most of the fluid drips down on the transmission cross member.

I've got a 1997 f150, 4.6. It sat for year and a half, trans went out and it wasn't my primary vehicle so wasn't to worried about fixing it. Until now, well got a new trans put in it, fired it up. And had a misfire, #3 and #8. Changed plugs and wires, same thing. Getting spark at the plug. So I changed both injectors, still nothing! I'm kind of stumped now.

The trans fluid appears to need to be changed. I do not know if it has been changed in the past as this 2001 F150 with a V6 truck is new to me and has 88K miles. I am wanting to drain the torque converter as well as drop the pan and change the filter. I am willing to take the risk of having to rebuild the transmission if the flush junks it up.
Three Questions:
1. Is there any issue with mixing the synthetic with ATF fluid as there would still be ATF in the cooler and other places unless I take it someplace and have it mechanically flushed?
2. Is there a way to determine if my 4R70W trans has a drain plug in the torque converter with out getting under there, looking thru the inspection port while some one is clicking the starter?
3. Is there any reason not to put a drain plug in the pan while it is uninstalled?

I pull a 23 ft travel trailer with my 99 f150 4.6l and so I decided I needed a trans cooler just to be safe towing in the dead of summer. I got a few quotes for right under 300. I couldn't justify the labor cost considering the cooler was under 100. So I made up my mind and decided to do it myself. I watched a bunch of videos for other makes and models but couldn't find nothing on my particular model year truck. I finished it today and I realized that my transmission fluid fluid is very dark. I have never serviced the transmission ever not even a drain and refill. I am going on my trip in about 7 days, and was wondering if I should even mess with anything to do with the transmission fluid. I put about a half quart of new fluid to top it off after the install of the transcooler but now I am worried that my transmission may not be in the best shape. Truck shifts fine as far as I concerned and acceleration is ok, so I am hesitant to do anything to it.

1999 F-150 4.6 4R70W transmission 148,000 miles. My transmission was slipping so I changed fluid and filter. I believe the transmission fluid was changed one other time (I did not find the yellow plug in the pan). Transmission fluid smelled burnt. Added new fluid and Lucas treatment. Turned truck on and the battery light came on. Brief test drive and no change in transmission until almost home and then it would not go into gear. Lights were dim power windows wouldn't work. Reverse works. I assume it is time for a new transmission and the electrical issue is related to the transmission. I use the truck a lot and am leaning towards getting it fixed. I can't swap out transmission myself and would have to take it to a garage.

My 2003 F150, 5.4L has been having some rough idle/misfires issues both at idle and under load.
I have fixed one big vacuum leak, replaced the PCV valve, new sparkplugs, seafoam and heet in the gas, replaced fuel filter, tested the fuel injector resistance. Coolant levels have not changed. The truck burns about a quart of oil every 1000 miles or so. The white exhaust is heavier than condensation, but it comes and goes. The rough idling comes and goes as well, and it usually happens under load and the CEL flashes.
The codes I get are random cylinders, po303, po308, po171, po174 were the most recent but there have been other cylinders as well. I clear the codes after each attempt to fix it and they come back different.
I notice that there is a small exhaust leak that drips water just behind the engine, and when I shut down the truck a lot of water will pour out of an area just behind the cab on the passenger side as well as out of the bottom of the muffler (small hole, looks drilled).
Usually the rough idle occurs after filling up the tank, but from different stations so I do not think it would be watery gas. I use Heet every fill up as well. Also, there is a sulfur smell after the rough idling occurs (catalytic converter?).

Well I went about 20mi to pickup a door for my inlaws. Get about a mile from home and my tow haul light is flashing. Truck starts shifting strange then I smell it trans fluid. If course I get stopped by a red light shut it down. Started and had to rev to get it to move now four houses away from home coast into the drive shut it off and trans fluid is covering the entire bottom of my truck. Even the rear tires inside are covered. I had the wife crank it and I blew a trans line near the ext. trans oil filter. What are the chances that I did not toast my trans? No prior shifting or slipping problems before this mishap.

My wife's 03 Passat w/ 1.8t is bucking and lurching throwing a P0301 (Cyl 1 misfire) code. We have about 58k on the engine and had the dealer do the 40k service 2 years ago.
So far I replaced cyl 1 spark plug, swapped and then replace coil pack with new. My choices for parts were limited on a Friday night and these are el cheapo Autozone parts. Still missing and throwing DTC, I don't really have access to Vag-Com anymore (just OBD reader at parts store) and I don't have a Bentley's either (I know there's some eye rolling going on now).
How to troubleshoot the cause so I can make a decision to take to mechanic or do a few more parts swaps between now and Monday. I've got tools and a multi-meter. I used to have Vag-Com but it isn't supported on my new laptop (Vista), I tried the USB extension cord on my desktop but it is hit and miss.

1997 F-150, 4X4, 151K miles, 4.6L. For years I've had an issue with heated air coming only thru the defroster, never the floor (a/c works normal). I've searched the forum and read many posts regarding the blend door. I pulled the switch and tested the vacuum hoses by taking a can of compressed air and blowing into the lines. All seem to be working with the exception of one, the black hose. I tried to follow it but short of removing the entire dash, I lost it. I read that there is a canister and small module in the engine compartment. Is there a way to test these to see if they're the problem? Where to look ? I only see one, on the firewall, passenger side, between the fender and the center of the compartment. Where's the other?

My 1999 f150 is having issues of bucking while going down the road and it only happen on a hot day. It's like someone is turning the key off then back on.It's only for a split second. I'm having trouble determining if this truck has the fpdm or not. and if this may be the issue. Fuel Pump Driver Module ?

I have an 02 F150 super cab Fx4 with a 5.4 engine. Earlier this week my wife pulled up to a stop light and the truck began to buck and jerk while moving. She pulled over and we had it towed back to the house. I pulled into the garage and something felt off, my first thought was rear diff clutches(the truck has 92k). I backed it straight out of the garage the next morning and it was popping and binding while backing up, it would move a little then act like it was up against a curb, then hit the gas, it would pop and move a little more. I popped the rear cover off the diff and the fluid was clean, and I did not see any metal shavings in it. Next I removed the rear brake disc to check if the parking brake shoes grenaded, they are fine.
Right now I have the rear end on jackstands, I put the tranny in neutral and turned the driveshaft by hand in front of the diff. It will turn in one direction and then not go back the other way. Not to sound ignorant, but is that normal operation of the traction lock diff? Next thing, while turning the driveshaft by hand, there is a clicking noise coming from the transfer case area. I slid underneath and could hear it coming from the case. Is this noise normal? I have no other truck around here to compare too. I have used the search function here at the forum, I am just not finding my particular issue. The truck was not in 4wd when this happened either.

I have 2002 4.2L F150 w/ Manual Transmission. The problem I have started about a week ago. I noticed it started to idle very rough and at times felt like it would almost stall if i didn't keep giving it some gas. Then a few days later it started to jerk/and buck intermittently while accelerating. I changed out the plugs and wires. My coil pack was replaced a year ago but was still under warranty so i installed a new one just in case. I cleaned and inspected the EGR valve and replaced the TPS. The rough idling seems to have cleared up but the jerking/and bucking still remains.
When the engine is cold the truck runs fine, and then as the engine starts to warm up it will jerk and buck while accelerating at any speed. Once the engine has reached its optimal temperature the jerking/bucking goes away and it runs smooth as silk. I can drive it for for a few hours with no issues whatsoever. As soon as the engine cools, the cycle starts all over again. I figured maybe the intake gaskets were on their last legs and when they heat up they seal tighter causing the engine to smooth out.
So I replaced the upper and lower plenum gaskets today and cleaned everything up. It still did not fix the problem.

I just got my 2003 excursion v-10 gas and its bad but when I'm towing my camper it weighs 8500 lbs empty and I'm trying to back it up on the beach the tranny ( when I'm in reverse ) starts spitting trans fluid out the vent on top ! went on fire twice ! the trans temp gauge never gets hot tho and other than that it works perfect, I was told this was a big problem?

I have a 98 with the 4.2.The troubles started with popping a little through the exhaust ,bogging down and bucking,rough idle and had the two codes together that deal with having bad intake gaskets don't remember the codes offhand.
I also noticed every plug in the truck was wet and black however it didn't appear oil wet.I have changed the fuel filter,spark plugs,lower intake gaskets,plenum gasket ,injector o rings,checked injector ohms all were 16.5,new EGR gaskets,all bolts are torqued to specs
Now I have a no run condition, it will crank but not run. I heard a pop in the engine one time. I cranked till the battery went dead.I also noticed as I was calling it a day last night the radiator reservoir was empty. I don't know if somehow I got a hydro lock even though I put new intake gaskets in it or i have some other issue like timing or something. I don't know where to look next....

Re packed / cleaned my hubs. Did a 600 mile trip and front driveshaft is locked again. Am trying for first time soaking them. They are in tranni fluid right now. I can't afford warn hubs. Is there any other tricks? Or will I have to soak them every few months?

I've got a 7.3 tranny that has had ELC Coolant and water mixed in with tranny fluid because of a bad radiator. I drained the fluid from the tranny a week ago and when I pulled off the pan today there is still junk in there. I'm planning on putting in a new filter, gasket and Mercon V but how do I clean the old stuff out of there? Picture.....

Truck has been taken care of, new Motorcraft plugs done 15,000 ago, never had any issues with truck until recently. Started bucking and kicking, threw CEL light, pulled codes. P0018, P0022, P0300, 305, 307 and 308. All of the misfires seem to be happening only on my left bank. I threw in a new camshaft position sensor just for the hell of it. This issue goes away and comes back intermittently. I drove it for a day and it did fine. Had power and then started it later to go home and it was misfiring, got to a stop light, cycled key and everything went back to normal. 2007 Ford F150 Lariat 5.4l Triton....116,000k....

I have a 1998 f 150 v8 4.6 ltr xlt. A mechanic told me that if my tranny gets hot the OVERDRIVE LIGHT will start to blink. It sounds strange to me, should I have a guage installed? I will be towing a trailer this summer.
