Ford Super Duty (1999-2016) :: 2000 F250 - ABS Light Is On / Blinking Overdrive Light Comes On At Around 25 MPH
Apr 14, 2014
The problems that I am having at the moment are that the abs light is on from the speedometer, odometer, also the blinking overdrive light that comes on at around 25 mph. After some research I had purchased a ford factory sensor for the rear dif. I then replaced the old sensor with the factory one. Started the truck and not a single thing had changed, both the meters were not working as well as the od light was still flashing.

I have a '99 F250 SuperDuty Diesel with an Automatic Transmission. There is a button on the end of the gear shift which allows you to turn off overdrive -- in other words the transmission won't shift into overdrive once you press the button.
Here's my problem. I start off driving normally. I've not done nothing to the overdrive button and the truck shifts normally into overdrive. 10-15 minutes down the road, the overdrive light (which indicates the state of the overdrive button) is FLASHING. Pressing the button doesn't stop the flashing. Once this flashing starts, the only thing I notice is a much more abrupt shift from 1 -> 2 gear.

I recentlyHad to replace the right front wheel bearing and after the install the speedometer and turn signals don't work, the ABS light is on and the overdrive light on the shifter is flashing. I've replaced the VSS on the rear diff, pulled and cleaned Speed sensors on front hub?

I have been having some inconsistency with my transmission in my 2005 F350. I bought it used 2 months ago and have had the low/tow overdrive light blinking. a month ago I removed the pan and changed the filter in the transmission. I had a friend run the diagnostic test and found transmission solenoid code as well as both cat. converters as well as my Number 8 cylinder misfiring... I pulled the transmission pan and filter to find what appears to be 7 solenoids? Where to start?

I have a 2000 f250 with the 7.3 and 181,000 miles on it, recently got stuck in the snow (in 2wd because i forgot to lock the hubs) and the rear wheels did alot of spinning. Now i randomly have the OD light start to blink, sometimes its a half a blink, sometimes it'll stay on for a few seconds, itll do it randomly while crusing down the road at a constant speed, also noticed my rpms fluctuate a tad at idle.

Tonight i noticed overdrive flashing. No changes in shifting, truck shifted fine. I shut it off when i got home, started back up, light was not blinking, not sure if its like the check engine light and stays on or not. Where light blinks but shifts fine?

Overdrive light started flashing this week on my 2000 F450 7.3 mason dump. It only does it when it shifts into 4th gear once it hits that gear at about 35mph the overdrive light flashes until you restart the truck and it resets. Does the same thing all the time but DOESN'T flash if i'm driving around town on back roads and never get to that gear. Could this be something minor besides the transmission starting to go? It drives and shifts fine even when the light is flashing. I wait to get the error code read?

had a problem with their OD light blinking and shift problems. This past week my od light started blinking and when I shifted into drive, it was stuck in overdrive. When I shift into 1st it would go to 2nd and stay there. So basically I had 2nd and overdrive. I started replacing sensors like the VSS, and checking the wiring warness. Took it to a transmission garage and they told me it was toast. Then I decided to bite the bullet and buy a new tranny. After replacing the tranny it did the same thing with the same codes showing. Then I got smart and checked the fuses. Of course it was as simple as a blown fuse causing all the trouble. In my truck it was fuse 23 under the dash. A 20 amp fuse that was listed as engine control. Im not saying that in every case if the OD light starts blinking it's as simple as a fuse but in my case it was, so lesson learned. Always check the fuses first.

I have a 2001 F250, 5.4, 4X4. My ignition key stuck in the start position and when I pulled it back to the run position, everything seemed ok. As I started down the road, my speedometer stopped working and my overdrive light was flashing. Also my turn signals had stopped working and my A/C clutch didn't engage. Figured I burnt a fuse. I looked in both the under dash and power distribution box and all seemed well. I checked the fuse for the turn signals/flasher and it was fine. The flashers worked. Thought I might have fried something so I replaced the ignition lock and switch. Also my service engine light came on throwing a code for the vehicle speed sensor.
Looking for solutions on this forum and the internet, I learned that the turn signal switch could have gone bad and the VSS sensor is on the top of the rear dif and an easy fix. Well replaced the sensor but nothing changed. So I went back to the fuse box. Examined every fuse, big and small and I found a 10a with a small space. This was #24 under the dash. From the manual, "#24, 10A, A/C clutch, Blend Door Actuator, Trailer Tow Battery Charge Relay Coil, Four Wheel Anti-Lock Brake System (4WABS), Turn Signal." Replaced it and everything went back to normal. Turn signals work, A/C clutch works, no flashing overdrive light and speedometer works. All from a 10A fuse. If you have any of these symptoms examine all the fuses carefully. There's a 20A fuse for turn/hazard lamps and this other one buried that's only 10A.

Driving to work the other day my transmission shifted down and the transmission light started blinking. It felt like it geared down like it was in 4x4 I was doing about 55 at about 2600 RPMs. This has happened twice now and lasted around 2 minutes then stopped and ran great.

So here's the deal: My 2000 F250 has began to have the overdrive light blink when I am traveling at low speeds <40mph and it is accompanied by strange shifting (lower gear for a longer period of time). As soon as I get up to highway speeds the blinking stops and goes back to normal operation. But as soon as I go back to low speeds it happens again. When I put the truck in to park when it has the light blinking it revs it self to about 1200rpms then goes back to normal idle. This truck has 228k miles and is on the original transmission.

Truck : 2000 F250 XLT A/T 6.8L v10 4x4
Issue : O/D off light is flashing on the shift lever. In a drive gear (R, OD, D2, D1) there is very low power when giving it gas, more so from a stop. In P and N, I can rev the motor with no obvious issues. In O/D, I can't even get forward momentum going from a stop when on a slight incline. When on flat ground and in O/D, flooring the gas only gets me going a few MPH and RPMs don't go above 1500ish. When selecting 1st or 2nd, the truck still struggles a bit from a stop but does get up and going.
What happened leading up to the issue : I was on the freeway driving about 80MPH without cruise control se,t and with O/D on as usual, when the blinking O/D off light caught my attention. Not knowing at the time that this was a transmission problem light, I started pushing and holding on the O/D on/off button to try and get it to stop. Probably about a minute later, I realized I was losing speed even when giving more throttle so pulled over to the shoulder. I shut the truck off and restarted it, noted the Service Engine Soon light was now on, then I put it in O/D and gave it gas but only got going a couple MPH which it sounds like the engine was choking/struggling. I then tried D1 and D2 and, while still struggling a bit from stop, was able to accelerate up to 35+ MPH.

Troubleshooting : Transmission fluid check looks good (full and red)
Checked fuse 23 of the Central Junction Box
Held a ground wire to bottom of Transmission pan and to the frame while I started the truck, O/D light still flashing
Wiring looks good coming to the plug on the driver side of the transmission
More info:
- No "Service Engine Soon" or blinking O/D off light prior to all this happening.
- I don't believe I'm getting 1st gear. I don't recall if I got my speed up to 30+ MPH while in D1, but while in D2 I never noticed a shift from stop to ~35MPH. At 35MPH, my RPMs were around 2500 I believe.
- While cruising at 35MPH in D2, shifting to O/D results in lost power. I had to stay in D2 all the way home.
To do (I believe):
1. Check shift solenoids (looking for DIY info)
2. Check shift solenoid pack (looking for DIY info)
3. Check TCC solenoid (looking for for DIY info)
It sounds like there are a couple shift solenoids to check as well as a solenoid pack (how best to check these out, I'm still looking for)?

ive got a 2000 v-10 excursion with 111k. Never had a problem like this before but last week I was driving home an noticed the theft light blinking while I was driving. Got home shut it off. next morning went to start it and nothing! when the doors open it makes a clicking noise under the dash. if I jump it the truck will start right up. If the batt is disconnected them re-connected it will start once until turned off and then nothing until its disconnected again. I ve got an elk hunt in 2 weeks and need to figure it out!

My Ford 250 Super Duty, it is a 2008 model. I can't get it to start and the anti-theft light keeps blinking. At least i think it is an anti-theft light, a blinking red lock on the instrument panel. I bought this truck from an auction so I don't have a manual, neither do I have a key set with the push button stuff on it. Just 2 electronic keys. Someone suggested unhooking the battery overnight, and someone else suggested pressing the valet button. I found a button under the dash, I have no idea if it is the right one.

My truck is acting up. Last night when I was parallel parking I noticed the RPM was jumping, I then noticed the OverDrive switch was blinking. I turned off and turned it back on and the issue went away. This morning on my way to work, it did exactly the same and it automatically corrected itself. The overDrive ON/OFF light keeps blinking.
My truck : 7.3 Diesel, Auto trans, 86 K Miles, Super Chip.

1. About march 1, my check engine light came on- took it to oreileys for a scan and said Speed Sensor A (cannot remember code), I was not overly concerned to fix it very very busy.
*Drove about 800 miles no further issues except the annoying CE light*
2. ABS comes on a few days ago
3. Today the truck, 4 miles from home decides it wont let RPM's get above 2500, and 40mph. It slightly hard shifted once.
Truck has 97000 miles and is a 1999 V10 has NEVER had any tranny shifting issues or engine issues....
4. Check tranny fluid when we get home it does not smell burnt and is red- its not even that warm...
I have read a couple places that a VSS can cause this? But I never noticed my speedometer acting up EXCEPT for the day the CE light came on- which there was a lot of ice and tires were spinning and speedometer said 0.

I have an '01 F350 super duty dually, 7.3L, auto trans. Over the past weeks my overdrive light on the gearshift would flash intermittently, maybe once every couple weeks. I chalked it up to a prior theft attempt where the steering column was damaged, and had turn signal/hazards issues after that.
Over the past few days my reverse gear has taken longer to engage, and is hard getting into the higher gears at speed. As of yesterday, reverse is out and won't shift out of second. Fluid level is good and clear. Could this be a PCM issue, or some sensor or relay?

I have a 2010 f250 XL v10 6 speed 4wd. I was looking into adding factory fog lights to it. I have the factory plug by the headlight. I've read that some XL trucks just need the fog lights, wiring harness for the lights and the headlight switch with the fog light option.
So today my buddy (has an 09 f250 xlt with factory fog lights) and I decided to try his headlight switch in my truck to see if it would send power to the plug by the headlight. Plugged it in, turned the fog lights on and had no power. Actually the little fog light light on the switch didn't light up that I noticed either. So we compared wiring harnesses going to the headlight switch. Both trucks have 9 wires. #21 fuse in the kick panel is intact and good.
What else my truck would need in order to use the factory fog light parts? I know I could run new wiring and use an aftermarket switch but I'd rather it be factory.

I currently am driving a 2001 F-350 V10 SuperDuty, and recently the battery light was blinking. I replaced the alternator in it, but it didn't work. I thought it was bad so I went and got another and it still didn't work. Turned out that the alternator wasn't big enough. I then went BACK and got a larger alternator, and it still won't work. Now the battery light is solid, and I'm getting absolutely no charge out of the alternator. I checked all the fuses and nothing is wrong. It seems like all the things you think could be wrong are running perfectly fine! What could be wrong. The truck will start, and idle, but will run off the battery only.

The battery light blinks in my truck. It's not a controlled blink, but it flickers like a loose bulb. It started a week or so ago. It would blip every once in a while. Gradually it would start to flicker more often. At first I thought it was belt-related but it isn't related to the transmission shifting at all. So if you're thinking that it's belt-related, you're going to have to explain why it doesn't blink either right before or right after a transmission shift (i.e. a rapid change in engine speed).
Earlier in the week, the light was flickering so hard that it was virtually on. I drove home last night and didn't see it once, although that's the first time I haven't seen it happen at all in a week. The battery gauge itself doesn't move a bit while this is happening. I have a cigarette lighter voltmeter and it shows a pretty steady 14.1 volts regardless of whether the light is flickering or not.
I had the batteries tested in my truck by a real battery shop about 4 months ago and they are fine. The battery connections all seem tight and clean, and the belt, tensioner and all that seems fine. So..What can cause a battery light to come on that isn't voltage related?
