Ford Super Duty (1999-2016) :: F250 - Overdrive Light Blinking / Abrupt Shift From 1st To 2nd Gear
Feb 16, 2000
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.

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 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 2006 F250 with the 6.0 PowerStroke and automatic transmission. I just purchased this truck at an auction about a month ago.
Today I notice the transmission is not shifting into overdrive. No warning lights. If I press the tow/haul button in no change but the tow/haul light does come on. If I press it again (to turn it off) the tow/haul light goes out but still the transmission will not shift into overdrive.
This leaves me at about 2000 RPM at 68 MPH. I just had a Ford dealer perform Transmission service last week. (20,000 miles after the last recorded service.)
I am already not happy with the service I received at the dealer so I am really hesitant to take it back to them if it is something not related to the transmission service they performed.

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 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?

Friend parked his well working truck and when starting it up after sitting a few days it won't shift into any gear. Lever moves as normal but the truck won't move. A soft clicking sound is the only difference to be noticed when shifting the lever. where to start? Temps are below freezing here if that matters.

I may be going to look at a 2001 F250, 4x4 with a V10 engine tomorrow. I think it is a shop truck for a business. The owner said that the mechanics told him that the trans won't shift out of low gear. It is an automatic. Maybe something as simple as a modulator valve (do they still use them)?

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.

I have a 99 f250 with some procomp (325s) that are 12.5 wide with a 6in lift my superchip tuner can change the trannys shift points but I am pretty sure a new gear ratio is needed. I dont do a whole lot of off roading with it its mainly my driving around and highway rig whats a good gear ratio that would work for me

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?

I was driving down the freeway the other day and when I hit a rough patch of road, nothing major, the truck sputtered and the 4x4 Low light blinked a few times on the console. I was driving in 2wd at the time. I kept driving and every bump I hit the truck sputtered as though trying to shift and the light blinked. On smooth road it didn't happen.
Today I drove to work at 6:30AM (40 miles), no issue. At noon I drove home and the issue started again. Every bump I hit the light came on and the truck seemed to want to try and shift into 4x4 low.
I got home, parked the truck for a few hours, then went out again, no issue. But about 20 minutes later it started again. I pulled over shifted to 4x4 high, drove it, was fine, went into 4x4 low seemed fine, went back to 2wd drove it some more issue came back. I've read tons of online threads regarding 4x4 lights etc, none like this and none on F250 Super Duty (2008).

Kevin here, and I'm a newbie. I recently purchased my first 4x4, a 99 F250 with ESOF. Last night I had put it in 4high for a rough road turn-around and then flipped the switch back to 2H, the 4x4 light didn't go off. Then when I got to the house (about 1/2 mile), it rolled when put in park and now it won't go into any gear.

I recently purchased an 02 F250 v10 4x4 with 150k from a local auto auction. The transmission, for lack of a better term, will "grunt" when going into third and in and out of overdrive. It doesn't seem to slip at all and the fluid looks slightly discolored, but it does not smell burnt. No Torque Converter whine either. A friend of mine who has owned 10+ SDs for his business said I may need to replace the TCM. Not too sure about that, because other than the strange noise, the truck seems to shift normally.

I just went from 3.73 to 4.30 gears on my 2007 f250 6.0. It has the standard Sterling 10.5 rear and Dana 60 front. My mechanic friend who did the swap said the ABS light came on during his test drive but the truck drove fine. I was of the understanding that the truck would not need to be recalibrated for proper speedometer and transmission function, but what about the ABS?

The switch for turning overdrive off that's located on the auto trans shifter stopped working. I've taken off the column cover to see if the wires have been severed from the tilt wheel, but nothing wrong there. I also checked the fuses, and all is well. Is it possible that the switch is bad at the end of the shifter, or somewhere farther down the column?
