My '01 7.3 is having some transmission problems, My O/D light is flashing. Trying to go after stopping at a light is a difficult, it drives very sluggish, like its not in overdrive. Scanned it and got three codes P0732, P0720, P0503. I replaced the ABS/VSS on the differential and the problem still exist.
View 1 RepliesI have a 2003 Ford f250 5.4l brought it to the shop today and they said the pcm isn't communicating with the trans. The truck hesitates and stalls out at a stop. idle is OK a little studder. OD light blinks also. I put new ho2s in, new oss from ford, new plugs and coils (motorcraft).

So the truck drove fine yesterday had zero issues... I used my auto start as I do every morning in this cold weather, get into the truck and shift from park to drive and its like it does nothing. I can free rev in N,D,1,2. Reverse works great.
I tried switching from 4wd to 2wd, no change. Reverse works just fine. No noises, codes or anything, just doesn't want to engage...
I am assuming I have a 4R100. Could something electrical cause this? I am thinking its mechanical, but hoping someone has ran into this before.
Literally no way I would have known the trans was going bad... It's always worked fine. Tranny fluid is full, I tried unplugging the battery waiting and plugging back in, no dice.
I have a 2001 F250 Super Duty with a 5.4L engine, regular cab. The truck has 149000 miles on it. I bought it about a month ago and had the transmission rebuilt, the spark plugs and coils replaced. Apparently the shady dealer I bought the truck from had power washed the engine and there was water in 3 of the spark plug wells on the drivers side. When I got the truck back from the transmission shop and backed it out of the parking lot, the OD off light started flashing and the SEL light came on. The code showed to be a P0720 to which the mechanic at the transmission shop replaced the speed sensor on the top of the tranny.
He said if it comes on again then the speed sensor on the rear differential could be the problem and that he would have to charge me to replace that sensor since it isn't covered under the warranty for the transmission.. I replaced the sensor myself on the rear differential yesterday and thought the problem was fixed. I drove the truck around for 30 minutes with no problems, until I put the truck in reverse, then the OD off light started flashing and the SEL light comes on giving the same P0720 code.
just bought a 01 f350 v10, 40,000 miles, plowing beast, anyways when taking off truck seems sluggish, give it more gas as its fine. At idle there appears to be a skip. There are no check engine lights on, could it be the coil pack or even maybe fuel problem? Have done plenty to this beast to get it close to perfect and this motor issue is it.
View 14 Replies2001 F250. I have had issues on other trucks where you get a funny-acting speedometer with a code that comes up as VSS (sensor on top of the rear differential)....And it shifted exact same way.
My new truck speedometer is totally fine and the ABS is on with codes:
C1158 Left front speed sensor coherency malfunction
C1155 Left front speed sensor input circuit malfunction
Shifts about the same way on the trucks with bad VSS.
Question is will a bad front speed sensor affect the way the trans shifts? Doesn't happen all the time. If you go slow it shifts smooth. If you pull off fast a barely noticeable jerk from 1-2 and 2-3....
Today I ran into a person I use to work with and was informed he had bought almost the same truck as mine. He also informed me that his has spent most of the winter in the shop. Reason being he claimed the transmission had a sensor that malfunctioned when it's cold out. This sensor lets the truck turn over but it blocks the truck from starting. Now it has got to 10 below zero only once this winter so far, my truck is kept outside, no problem yet.
View 3 RepliesI have a 2000 ford f350 7.3l with a auto transmission(4r100) and I have had problems with it . It started a while back when the transmission is cold like in the morning when I put it in drive it acts like when you don't push the cluch in on a standard when coming to a stop kind like it's bucking and this only happens when it's cold when it's nice and warmed it's fine so I changed the whole transmission and put a billet torque converter and I'm still having the same problem can it be a sensor or something electrical ?
View 14 RepliesI have a 2002 F250 SD V10 4x4, that just started to randomly misfire [does not matter if the vehicle is in motion or in park]. I scanned the OBDII and found pending code P0720 (Output Speed Sensor). The CEL, O/D light, nor the ABS light illuminate. The speedometer functions normally.
This occurred Saturday after we got 12-18" of snow. I cleaned out the driveway, took a short drive (~ miles) & parked the truck (no symptoms). Later we went to 2 stores and then on the way home, the misfire started. The next day the misfire continues.
I have been searching & come up with the same posts that say the issue is not the OSS. It's usually a bad COP or bad wiring @ the OSS. The symptoms are not the same as when I had a COP go bad (only misfired under load between 1500 & 2500 rpm).
Personal issues: My truck does not fit in my garage, it's dark (and usually below 30 F) before I can get to look at it in the evening. Also, we are supposed to get another foot of snow tomorrow night.
I have a 2000 F350 7.3 4x4. It began giving intermittent tow/haul flashing light, when going up or down hill but would clear and drive next time truck was cycled off/on. No ABS lights and code reader generated P0720 for the output speed sensor, now I can get it to generate just driving slowly fwd and rev a few times. All of this has been in the last few days.
Truck will stall if I take it up a slight incline with the fault. I replaced the sensor on the top front of the 4r100 transmission and also replaced the sensor on the rear differential after giving up on looking for an output sensor on the transmission. I know the 2WD transmissions have an output sensor but is there one on the 4WD version? I have read several past threads discussing the P0720. I am hoping to confirm what sensor I need to be looking at and where it is located in this application.
For the last few weeks I have noticed my transmission overheating a bit, nothing bad, but I have just been running around town local so no drives over about 15-20 mins.
Well, Friday night I went out to see a friends band play about 40 mins away, My trans temp climbed steadily the whole way out there, peaking at 226 by the time I got out there. I kinda took my time getting home hopping bars to give the trans a break to cool off.
Did some diagnosis today, first thing I did was unhook the line going to the rear of the transmission and did the bucket flow test. I fired it up and fluid came pouring out of the line which goes into the rear of the trans, nothing really came out of the rear of the trans, it was all out of the line.
So that tells me that its getting flow through the coolers. I didn't measure the amount like some do, but I can tell you it looked like a strong steady flow.
I made sure the fluid levels are proper as well which they are, it was maybe a 1 quart low which shouldn't effect anything. I also inspected the coolers and everything appears to be clean with no airflow restrictions. Took it out for a brief drive again and it climbed up to 147, maybe 5 miles out 5 miles back. Ambient temp is 62 today.
I am getting multiple codes on my Edge Evo which I have had set to stock settings since I bought the truck. Codes I get that concern me relevant to the trans are P0741 and P0743. Both seem to relate to the torque converter.
I feel like my RPMs are a bit to high at highways speeds so I am wondering if I have a TC that is slipping a bit while driving. I did notice a bit of a metallic pearl in the fluid that came out. Aside from that I feel like the trans is shifting ok, though sometimes I have to let off the gas to get it to shift into 4th.
Just got the transmission rebuilt in my truck and other then shifting hard sometimes it has been doing great, Hooked it up to the goose neck this evening and everything was fine then went to back it up and pull it forward and after a short distance the od light was flashing and when i ran a check on it it was p0720? The transmission has less then 1000 miles on it?!?!? 1999 Ford F-250 7.3 Automatic....
View 5 RepliesA few weeks ago I noticed what seemed like a "slip" in my automatic transmission. Only happened a couple of times and I thought maybe it was just me imagining it or I didn't have the shift selector lever firmly in "D"rive. Then I went on a 4,000 mile trip pulling about 3,500 lbs. on mostly flat roads but it did include some 7% grades in the hilly parts... the truck performed flawlessly.
This is probably not related but ... after I got home, the truck sat for a few days and then I noticed a coolant puddle under the truck. Traced it down to what appeared to be a slow drip from a bad squeeze clamp on the large, lower rad hose connection. Replaced the squeeze clamp with 2 worm drive clamps and no leaking issue since.
Then last night, the tranny seemed to "slip". My short run across town started out OK. However, when I arrived at my destination, the diesel motor would rev to around 2500 rpm but the truck barely moved forward. It eventually did shift into second but also with high revs. It was the same feeling as if it were a manual tranny and you were giving it lots of throttle but only letting out the clutch a little bit (i.e. riding the clutch). This happened a couple of times last night. Also at a stoplight with the brakes on firmly, the truck was gently and rhythmically "rocking forward" as if the tranny was not fully disengaged.
When I worked through the gears shifting manually, the problem seemed to disappear and the truck responded going through the gears normally. Upon restart about an hour later, tranny shifted fine both in the city and at highways speeds on the way home.
B-I-L commented "sounds like your clutch is slipping". Not exactly sure what he meant as I had to leave. I'm hoping this will be a simple fix/adjustment and not the dreaded mechanical diode failure leading to a replacement tranny. Truck only has about 75,000 miles on it.
I'm suppose to head out on my annual vacation next week carrying a 3,500 lbs. truck camper and pulling a 3,000 lbs. cargo trailer with our gear. Obviously if the truck is sick, this trip can't happen. I know some of you would dive right in and start taking the tranny apart to repair it ... What is wrong with my transmission and what I should be doing next?
My '05 5.4 SD CCLB is running badly. 95k mikes. Plugs done 6 months ago. Acceleration is very sluggish. Sometimes uphill from a stop is almost impossible.
No CEL codes other than an intermittent coolant temp gauge that spikes but resets as soon as I shut down and restart.
When it is bogging the exhaust note changes - almost like there is a blockage. It is almost a booming sound. I would like to test to see if the cat is clogged. I have a vacuum gauge but need to find a vacuum source after the throttle body to do so. If I pull out the O2 sensors ( to allow the exhaust pressure to exit ) would the truck run badly because the O2 sensors were not functioning?
If it turns out that the converter is bad. Can I just eliminate the cats? I do not need emissions testing here in PA because the truck is so heavy. But I don't know if eliminating the cats will cause other problems.
2016 F250SD XLT CC 4X4...13K miles... Now with it being blazing hot in Florida I have been running windows up and a/c on. Beginning to notice the truck is not accelerating the same with the a/c on as it does with the a/c off. It seems like it sluggish till it gets to a certain RPMs then you feel it kick in and somewhat take off. Is this normal?
View 7 Replies2002 f350 7.3 ... problems started all of a sudden one day. I have an edge evolution tuner in my stroke. I have it set to make all of my shifts firm. One day it started shifting really sluggish between 1st and 2nd gears only. It don't do it all the time, but it does it more often then it doesn't. I have also noticed when i come to a complete stop and then start out again it seems that it doesn't downshift all the way back to first and when i hit the gas it seems to kinda be stuck between gears and it barely moves until i get the rpms up before it will ease its way into 2nd and the converter locks up.
It shifts a through all the other gears just fine nice and firm like it should, its just the shift between 1st and 2nd. Im wondering if maybe it might be the speed sensors or maybe the tranny filter is getting clogged up? The fluid in it is still nice and red and up to the level it should be. I just bought the truck in october and the fluid was nice and red when i bought it, but who knows if they changed the filter. I have had NO tranny problems with it up until a few days ago when this little problem started.
I have a 2001 F250 Super Duty 5.4 Triton motor with a Transmission Leak. I have drained the Transmission, replaced the Transmission pan gasket and filter. The auto parts store also had me purchase the Torque Converter bearings/seal along with enough transmission fluid and a bottle of Lukas Transmission fix. Do I really need to replace the bearings/seal if I have everything else already ?
View 2 RepliesBought this truck a few months back. Nothing but problems. I always thought it has felt a little underpowered and hesitant. I chalked it up to being a 5.4l in a f250. Well now im thinking it has been a symptom all along.
Lately, the truck has been stalling at stops. Randomly, but not often. The truck idles at 750rpm when I start it, but after driving and then coming to a stop while in overdrive it idles at 400rpm. This seems too low to me.
It hesitates occasionally when giving it throttle. Just today it got really bad and was almost unresponsive. I would hit the throttle and it would just idle while randomly kind of shooting up in RPS and shuddering. It finally produced some error codes, it looks like, but I am afraid to drive it all the way to the autozone.
I am thinking TPS. Is the TPS attached to the pedal or is the TPS attached to throttle body under the hood? I've read some conflicting stuff about this. The good news is that if it is the TPS then it should act like a whole new truck after I replace it.
My 2003 6.0 truck lost most of its power. It has the SCT programmer. It used to run great it would roll coal really well then it slowly started to run worse. Now it runs really sluggish especially when its cold. IT takes forever to warm up. On the freeway when ur going a constant speed it bucks and jerks a lot. It won't roll coal anymore and just runs like crap. A mechanic said I had 3 bad injectors. But I don't believe it.
View 2 RepliesI have a 2009 6.4L F250 with 153k miles on it. Yesterday I drove from downtown Dallas north to McKinney (about 40 miles) and truck was running fine. Left approx. 3 hours later for dinner and the check engine light came on and truck ran very sluggish with hardly any power. Had it checked at auto zone today and got the P040D Exhaust Gas Recirculation temperature A circuit high DTC. I can get the part but not sure if I can replace it myself.
View 2 RepliesMy buddy's 2001 7.3L F350 has had 3 transmissions. Rebuilt and used. Once the new trans is in he goes like 15 miles and then is starts shifting hard and grinding gears. What this could be?
