Ford 7.3L Power Stroke (1999-2003) :: 2000 - Overdrive Light Blinking Only At Low Speeds
Oct 24, 2016
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.

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.

Took a 2 hour trip got of the interstate came to a stop light and the OD light starting blinking cut the truck off at the light fired it back up shifted in every gear like normal drove a little ways stopped at a light and OD started blinking again cut truck off back on light. Went away shifted great threw all the gears.

Auto trans. The Overdrive light flashes on the Selector lever. Never stops.I put tape over it because it is annoying. Especially at night. It goes into overdrive no problem.
A Couple of times it did not flash and was stuck in first till I manually shifted. Then the light started flashing again and works normal. What now......RPM Sensor?

OK, truck is 2000 F350. I am heading on a 2000 mile roadtrip to Yellowstone for my wife's 40th birthday in two days. What was our rock of a vehicle is now causing me severe anxiety.
Over the last few days the truck has been difficult to start - almost stops turning over as if the batteries were low. So I ignored it because if I plug it in, it starts fine and if I drive it and it gets hot - it starts fine.
Tonight while driving - I noticed a high idle and then it went to normal - I thought it was weird and a few miles later at a stop sign it struggled at idle, sort of loping but not romping very high and the over drive light started blinking. When I got home when I went from drive to neutral it goes to high idle and then the overdrive light blinks. The first time it blinked it went off when I pressed the OD button - but now it continues to blink.
Would low batteries be the root cause of this? I will continue my search for blinking OD light but I thought I would get this in the queue in case this is bigger than I can handle. I have 48 hours to resolve this issue - leaving Wednesday early morning.

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.

The overdrive light is flashing but not all the time. What does this mean?

My F350, 7.3 L. is flashing the overdrive light. Had a pro do a scan that said no Turbine speed sensor signal.
I would like to know where the TSS is located and then see if it has corrosion other reason not to connect.

I have a 2001 3/4 pickup. Sometimes the over drive light flashes. When it flashes it shifts really hard and sometimes it won't shift into 4th until I mash the overdrive button. Sometimes the light doesn't flash at all and it doesn't have any trouble shifting at all. Is it a solenoid? Or wiring issues?

So my OD light started blinking on the way to work today. The fact that my truck dropped out of cruise control and then started downshifting out of OD on the freeway and back into OD started this ordeal. A quick scan of the dash made it easy to notice the OD light strobe, especially in the dark.
I've read some posts in the past in the event it happened to me since my truck is far from new. I had it in the back of my mind that I would attack the VSS sensor with some contact cleaner then replace if that didn't fix the problem. Doing a search revealed a far greater spectrum of culprits. In addition to the VSS potential I have read about transmission handles, chafed wiring in the steering column, and even the transmission itself. Instead of re-inventing the wheel I'm looking for those that have more knowledge on this issue than I do. Here are my symptoms:
1. Drove 5 miles from my house to the freeway with no issues.
2. Shortly after getting on the freeway I set my cruise control at 65mph.
3. Shortly after that my cruise control 'dropped out' and the truck started to slow down (obviously).
4. When I got back up to speed the cruise would not work which is when the out of OD and right back into OD started. It did that all the way to work (it would go out of OD and back in every couple of minutes or so).
5. Transmission hunted on surface streets too (25mph).
6. Turned the truck off, waited a couple of minutes, then started it back up. OD light is off and truck drives fine.
A couple of things to note. This is the first time anything like this has ever happened with the truck. Also, I have Torque Pro and my instantaneous MPG meter was at 0.0 the entire time this was happening. When I turned the truck off and back on, the MPG was displaying again normally. This is what made me thing something with the VSS connector.
I decided to search the issue and confirm my suspicions then found out that this could be a lot more difficult to pinpoint. Since it cleared up when I cycled the key I am ruling out a transmission issue (for now).
I plan on cleaning the VSS connector (that's the plug on top of the rear axle right?) and then pulling the cover off the steering column to see if I can see any chafed wires. Is there anything else to check out while I'm rooting around? I will add that my transmission handle has always been loose (I think the original owner used to drive with his right hand resting on the handle).

I drove the truck to work. It was fine. I start it up at quitting time and let it idle for a minute. When I pulled out of the parking lot and the od light started blinking. After about 8 miles I stopped at a red light. When the light turn green and I drove off the speedometer is working again. The od light flashed for another mile or 2 then stopped.

Funny shifts and OD light blinking. Have p0741 and p0743 codes. Checked wiring and no visible damage. Checked continuity on the purple-yellow TC wire from connector under hood and at Trans and their is none.?? Also will I hurt the Trans driving this way if the temp stays in check?

I have a 2000 with a six speed and through the first 2 gears while giving it only a little throttle, worse on hills and worse while towing I have a pretty decent vibration. Once you get to 3rd and up its fine. I have read about axle wrap and due to the fact my springs are pretty wore out I think this is a big part of it. Any other things to look at other than new springs? The u joints all look and feel fine so I haven't touched them.

Speedometer not working and O/D light blinks, I have a 450 and a 250, 99 and 2000. On 450 this is an intermiting problem. Stop truck turn ignition off, restart and it all works now. Just started on my 250 and stopping and turning ignition off cures the problems for a few seconds, after i get moving the speedometer doesnt work and then light starts blinking again O/D light. Where do I need to start?

My overdrive light is blinking off and on. When I accelerate normally, the truck starts stumbling? (don't know a better word) some, sort of like a clogged air filter or fuel filter. I am going to take it to a transmission shop because its a little beyond me, but don't want to get ripped off.

165k miles 4x4 6 speed, bone stock unmolested
Slowly progressing problem over 6 months. Occasional miss at highway speeds uphill has progressed to bucking and jerking during even gentle acceleration attempts.
I hadn't got my cam sensor recall done but no change after that procedure completed yesterday. Oil recently changed as well.
I have a torque pro but it never finds any fault codes even though 'service engine' light comes on sporadically. I'm not sure I'm operating it properly but it at least reads rpm when its running.
I'm contemplating the hutch mod but I'd like to have an official diagnosis beforehand if its possible in my case.

I have a 2000 f150, the overdrive light flashes on the swifter, the motor has no power and sputters unless I put it in second gear. It won't shift gears in drive.

I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:
P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input
What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?

So I have a 2000 F-250 7.3 and my over drive won't work. I also had hard shifting from 3rd to 4th and 3 gear wouldn't try to shift until about 2500 RPMs which is high. I replaced solenoid pack and no change. I have rebuilt the tranny and found that OD snap ring had came off I put upgraded spiral ring on. When I went on a test drive I found out nothing had changed except shifted smoother. So I changed valve and accumulated body still no change. Truck is throwing 4 codes:
P0733 Gear 3 incorrect ratio
P0750 Shift Soleniod a fault
P0783 3-4 shift error
P0541 intake air heater a circuit low
Could it be PCM??
