Ford Super Duty (1999-2016) :: 4r100 - O/D Light Blinking - No Or Low Power
Jan 15, 2012
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)?

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.

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.

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 a 2003 F250 5.4 auto trans and I live in Minnesota where it has been -15 and my truck won't go. It has only half power it acts like its cutting out and it won't even hardly move in Drive if I put it in 1st or 2nd it will go or reverse but the engine is only half power the OD button is flashing the check engine light came on and I pulled the codes and there is 7 of them. I think its electrical issue but don't know where to start! Here are the codes, P0443, P0750, P0755, P0743, P0135, AND (P1747) which my book doesn't go that high?

My truck lives with a trailer behind it and I always turn overdrive off when under 50 mph and turn it off to slow the truck and trailer down when coming off the interstate. About a month ago when I turned od off to take a exit truck did not decel. Just shifts to 3rd and engine goes to idle even at highway speeds. Truck still tows fine. No trans codes no flashing od light. Trans was rebuilt at 163,000 miles have 183,000 now. I'm stumped to what it could be.

I have a friend who just burned up his transmission. He needs to get on the road as quickly and cheaply as possible (he uses this truck for work).
We found a local 2wd 4r100 out of a 2000 but it is for a 2wd rig. His pickup is an 2001 F250 7.3. 4x4.
What is involved in setting up the 2wd transmission for the transfer case. We can salvage parts from his old transmission if need be.

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?

My buddy has a 2002 F350 CC Longbed with a 7.3. Last night the overdrive light started blinking. He said he drove it today and it takes about a mile or so for the light to come on but then it is a steady blinking. Truck has about 254K miles on it. He said other than the blinking light everything seems normal. How to figure out what this issue may be?
I got AE hooked up on his rig.
When I pull (ALL) codes this is what I get:
When I pull (Current) codes I get this:
I tried to clear the code and the light stopped blinking, but he said it started blinking again on the way home.

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 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.

Bought truck drove it 240 miles on interstate 80 mph no problems---2001 F350 4x4 auto. Next morning backed out drive and trans fluid trail 6 inches wide. Didn't leak in forward gears (at that time) added fluid and drive to town shifted fine.
Next day gonna drive 150 miles to check out leak. (Son was driving it) said it wouldn't go over 40 mph. Revving high. Hauled truck here on trailer and pulled tranny. Rear housing cracked just before 4x4 adapter. (This trans was rebuilt 10k miles ago) ..
Got used 4R100 from friend who replaced only because he built one for his truck. It was shifting fine etc when pulled 6 months ago. Used cracked trans TC and installed. Test drive no 4th or OD. Pulled trans put TC that came with trans in. Still no OD. Put on scanner while driving. Trans is being commanded to shift to OD but not up shifting. 45mph at 2400rpm.
Pulled plug to solenoid pack inside trans ( this should make trans default to OD / limp mode) still no OD and won't go over 45.
Pulled OD button checked wires inside steering column. All looks great. Not even a heavy rub mark.
Should I replace the coil pack in trans? Where do I go from here? Again this trans was known to be good when pulled 6 months ago.

Recently I have had an issue with my auto which was just rebuilt. About 500 kays after i picked it up it shifts dangerously hard and immediately into all gears at around 20-40 mph, converter also locks immediately. The speed sensor in the box was replaced with the rebuild but I'm having it replaced again this thursday just in case.
Just for the record I cooked it on the beach a while back, the speed sensor was replaced with the rebuild as it was doing the above, the od light also flashes when this occurs, before and after the rebuild.
Prior to cooking it never had an issue.
What could be causing it? I'm starting to worry it cant be fixed, have done a google and tried a couple of things mentioned. Code says wiring issue associated with speed sensor in box.

The other day I was driving i was driving down the road when suddenly my truck wouldn't shift out of first gear, then the truck died and the motor wont turn over either. Acts like it is locked up. Its an 01 with v10 and 4r100.

I have a 2006 f250 5.4 4wd with 5r110w trans. Check engine light was blinking and then one day the tranny just stopped working in all gears. Engine code p0751 came up, shift solenoid "A". Changed it, code went away and still no gears. Checked pump pressure, good in all gears, all I can think of now is TCM....

I just recently got handed a 2005 ford f250 6.0 PSD from my older brother, new to the whole diesel game, well all of a sudden as i was driving down the road about 65 mph, trucks RPMS shoot to about 4K and tow haul light starts blinking as i start pulling over (still in drive of course) i realize i can't move anymore the trucks rpm just rev. In all gears it does not move i moved 1-3 D and R and nothing truck just revs. i had my father get under the truck as i shift from gear to gear and the linkage is moving back and forth on the transmission as i put it in reverse the reverse lights still pop on, I'm new to the diesel game...
