Ford 7.3L Power Stroke (1999-2003) :: OD Light Starts Flashing After Coming To A Complete Stop
Jul 14, 2011
I have a 2000 F-350 dually. I am having an intermittent problem with the the OD light. The symptoms are after coming to a complete stop the OD light starts flashing and when trying to move forward it feels as if the brakes are dragging and sometimes stalls out the engine. The codes read with a Superchip 1705 are p1670,p0720, and P0503. When I shift into park, the engine rpms jump from idle to about 1500-1600. I have replaced both the differential VSS and the transmission OSS but still have the same problem.

I recently had a flat tire - Schwabs fixed it. Then told me my rear brakes were bad so I replaced them. I noticed when coming to a stop the last 20-30 feet you can really feel the front end vibrate - almost like it is in 4wd but it is not. I checked the hubs and they are on auto and lifted the truck to spin the wheels and made sure everything was dis-engaged. My front rotors were bad so I replaced them and the pads thinking it was the root cause. I also greased the front wheel bearings using the little tool from riffraff diesel where you take out the speed sensor and insert grease.

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 am trying to make sense of a P0741 code accompanied by a flashing OD light.
The truck is a 2002 (12/01) build date) F250, 7.3,4x4, Auto, with 245,000 miles on it. The truck seems to shift fine but around 40/45 it feels like the TC does not lock, followed by the flashing OD light.
The transmission was serviced 500 miles ago but the OD light flash was intermittent until last week, now its been constant. I want to take care of it before I do any damage.

I recently started noticing that when I am coming to a stop(usually a quick stop), the trucks rpms drop to low. hard to tell how low but looks like around 450-500 rpms. I can feel the truck struggle just for a second then the rpms bounce back to 650-700. i was sitting in my truck while in park and was revving up to about 1200 and then let off the pedal and it died. My positive battery terminals are getting pretty bad and am going to replace them soon(waiting on parts). Could this be the cause?

I have a persistent issue with the OD off light flashing on my 2001 7.3L auto 4x4. Scanning it with AE I get the P1832 code. The truck runs and drives just fine. It shifts nice, goes into overdrive, locks up, etc. If it weren't for that blinking light I'd think it was all perfect. I've checked all the connections, replaced the range switch / neutral safety switch, replaced the VSS on the rear axle, checked all light bulbs and fuses. I've checked MOST of the relays in the truck.
I pulled the tranny drain plug and poured out a bit of fluid into a clean pan, it looks and smells good. AE also tells me that it's not communicating with the ABS system (although there's no persistent ABS warning light on the dash), the Airbag, the Overhead Trip Computer, the Parking Aid (which I don't have...), or the Enhanced Powertrain. The temperature on my overhead display is reading -40F which is clearly wrong.
I've looked for a comprehensive wiring diagram for the truck, but can't find one. I'm trying to figure out if there's a connector or module that these various functions go thru that might be the problem. Am I missing a ground somewhere? The frame was just powdercoated......am I not getting a good ground connection? In complete disclosure, I have torn this truck apart and re-assembled it out of several different trucks as outlined in this thread.

I have a 02 f250 4x4 7.3l.... I drove it all weekend and no problems. It sat till yesterday I got in it to go to church. It started up and had a little miss was around 60 f. Then the od light started flashing. Not in any code just constant flash. I was parked down in my drive way. It idled fine but acted like it wouldn't take fuel. So looked around and found the hose on the map sensor was broke.
So today I fixed the hose. Checked the oil level and battery connections. Still running weird and flashing od light. I got under the hood and wiggled plugs I unplugged the ice. It revved up then back down and started running smoothly. Got in it and it backed out of the drive way. It ran and drove fine. What I need to know is why??? The ice is a new one from Ford.

I test drove my truck yesterday for the first time with the newly rebuilt transmission. I was gentle with the right foot and all seemed well. Once out on the main road it shifted by itself into overdrive for the first time and immediately the O/D light started flashing. I drove it home and shut her off. I test drove it 2 more times leaving overdrive off, no issues. With a snap-on scanner hooked up I let it go into overdrive and O/D light started flashing again, not immediately maybe 5 seconds after shifting into O/D.
Codes are:
p1316 IDM codes detected
P0717 Turbine speed sensor circuit fault
P0715 Turbine speed sensor circuit fault
P0500 VSS fault
10 minutes ago was my last test, O/D flashes only after it has shifted into overdrive. I checked the transmission wire harness and all connections are tight, trans oil level is good & trans temp never went above 150. Could this be a faulty VSS?

Ok, I have a early 99 F550 that had a tired engine when I bought it about four years ago, but I kept using it just dealt with the low power and blow by. But last winter I decided the truck deserved a complete overhaul. New cab, new transmission, overhaul the engine, and everything else that goes with. I tore the engine down to find out it was already a ford reman. Had the heads completely gone through, new pistons, new exhaust manifolds, new turbo, brand new injectors, new 4inch exhaust, new valve cover gaskets uvch harnesses and repair ends for harness side, and a new IDM.
Now with everything back together, the truck starts an idles fine but has absolutely no power driving it takes like a half a mile to get to 45mph. No check engine lights no smoke. I took it to ford they said only stored codes were for ebpv which I deleted out of turbo housing they recommended changing injectors. So i did no difference. They also said my hpop was about 1600 at idle. And said that's enough pressure. I did resistance readings on all wires between idm an valve covers.

I have an early 1999 Ford F350 4x4 7.3. I purchased it used about a year ago. The trans was replaced with an ATS 4R100 and a billet torque converter. I have the paperwork for it to confirm it along with the mileage when it was installed. It currently has about 35k on the new trans.
Several months ago the trans heated up to about 200 degrees on my trans temp gauge that was already installed when I purchased it. Not a huge deal and after pulled over and high idling it off I went and no problems.
About a month ago I was towing my fifth wheel when I noticed the temp rising on a level grade. I also noticed the OD light flashing. I made it home and when I went to drive it the next day light was not flashing and it shifted and drove like normal without the trailer.
I towed the trailer again and same thing, OD light flashing and started heating up. I changed all the fluid and flushed it based on the trans flush procedure I got in this forum and replaced with an OEM trans filter. Towed the next day and everything was good. Temp was good and no OD light flashing but I lost 4th gear. All other gears shifted fine, no slipping, just won't go into 4th.
On my way back home the OD light started flashing again and instantly the heat started rising on the trans again. I was finally able to get it into 4th if I let off a little, but as soon as the OD light started flashing I lost it again.
I have a friend of a friend who works for Ford who offered to come over to hook his scanner up. When he hooked it up there was no stored codes from the OD light which we both thought was odd. Took it for a test drive and the OD light started flashing so we could get some readings. He said it showed an error shifting from 1 to 2 and another error when shifting from 3 to 4. I unfortunately forgot to ask him for the specific codes. He tried to read the torque converter info but said my truck was to old and the PID was not supported to read that info.
He said it appeared it was mechanical but without some type of break out box where he can physically shift the gears he couldn't say for sure if it was mechanical or electrical. He did not seem to interested in doing that test for me as he rebuilds trans on the side and said he could rebuild it for me.
It seems my overheating takes place when the OD light starts flashing. It still drives fine and shifts smooth with no issues with or without the OD light flashing. 4th gear usually doesn't work but on a rare occasion it will go into 4th fine which makes me believe it may be electrical.
I am new to diesels but have learned a lot about my 7.3 lately. I recently installed injectors, up pipes, hutch mod, and several other little things so I can get things done myself but am just a DIY'er who can follow good directions. I know very little to nothing about transmissions though.
While working on another issue I did notice there is a large wiring harness that connects up on the driver side of the trans. I unplugged it and was checking the wires and after removing the dirt and crud on it you could see the outside wire sheathing had deteriorated exposing the copper. I bought some liquid electrical tape and sealed everything up. I did look for a replacement wire harness at the time and the one I ordered was very similar but the plug was different so that is why I used the liquid tape at the time. I did not seem to have a problem at the time after fixing it but wanted to mention it here in case that may be an issue.
I also thought swapping out the solenoid pack may fix it. I did not want to drop the trans and send it for a rebuild if I did not need to. I know there are some other sensors associated with the trans like the TSS I think but don't know if they are even related to my issue.
I tried getting the codes from the guy but he does not have them and I can't get him back out. I have an OBDlink device connected to Torque on my phone but I couldn't get it to read trans codes. Could be user error.

Saturday morning my grandpa drove my F350 into town pulling our 4-horse trailer (With living quarters). I wasn't with him, but I was told the following: he started smelling something hot and noticed the O/D light start flashing. Now, this man is not the most intelligent man on the planet and uses the O/D to "slow down the engine" when he starts and stops - i.e. uses it as trailer breaks. I have asked repeatedly for him to quit, but as best as I can tell, he continues to do so.
After the burning smell, a driver pulled up next to him and pointed down - he looked to see smoke and the truck puking fluid everywhere. He said he thought the truck lost power because he couldn't get it to move. Ended up getting it towed. The tow truck driver checked my fluid level and said I had an extremely small amount of transmission fluid left in the truck...which made sense as the fluid was all on the ground underneath, lol. Fluid was NOT red and looked really gross and there was DEFINITE burnt smell to it.
My question is this - what in the world could have caused the truck to do this (I read that is could be from overheating?), and what should be my next course of action? It is home and in my backyard right now (Classy!). It starts and runs fine, but since there is little to no fluid left, you have to hammer down on it to get it to go anywhere. It does move, however.

Well, I've been getting a flashing OD light, so doing some research, led me to replace the shift solenoid. I did just that and have yet again the same P0741 code... The truck seems to shift normal but will randomly throw the code and then will not go into Overdrive as well as shift very hard into all gear. Where to look next?

2000 powerstroke 4r100 transmission. It has 155k just had it rebuilt and the shop is having a night as am I. It was shifting hard and the o/d off light would start flashing after you drove it a while. Its still doing the same thing and the shop checked the whole wiring harness and replaced the accumulator twice believing they got a bad re-manufactured one. The only code I can pull is a 605 pcm read only memory error. Could the cause be a bad pcm? The shop doesn't seem to have a clue at this point and I'm out 2500. IV taken it back twice now and Iv driven it a total of 35 miles since the rebuild...

We have a 2002 7.3 f350 2wd this darn thing is now tripping me out. At first when ou start the truck its all good but when it warms up the idle is funky when you go to stop at a lite its like im power breaking and rough idle once stopped the idle is about between 800 and 900rpms at a stop really high idle but plenty of power on take off...

I have a 2001 Ford Excursion Limited 7.3l with 199,980 miles on it.
It has a TS-6. My first problem is that when I come to a stop or slow down to a crawl then press the accelerator the engine stalls and dies. I have looked and looked at threads and can not find this example anywhere. There is no pressing the pedal and it remains at idle. It dies, shuts off, quiets. I have thought icp, tps, ivs
Second problem is that a/c is blowing hot. Other than being out of Freon, what could be other things to check. It does sometime go to default, but has done so in awhile. It does not blow cold in rear and hot in front. They both blow hot. I have replaced the pvh sensor.

I bought this truck with a stock automatic transmission and 260k miles back in October expecting the transmission to be the first thing to go. Recently I had a transmission code, OD OFF light flashing, for the bad speed sensor which i got replaced. Then the OD OFF light started flashing after some hard driving when I would put into neutral or park so I took it back to the mechanic, Hanahan Truck and Auto in Sc. They looked into it and there wasn't any different code in the system but they noticed when you lay into it driving it slips some between 2nd and 3rd gears so that could cause the computer to put in a code.
They said usually a rebuild runs from $2k-2.5k and they also recommended a Jasper reman for roughly $2.8k which comes with a 100k mile 3yr warranty. So I figure replacing the transmission is probably the way to go. Any recommendations for a replacement. I've heard ATS and Sun Coast are decent options that I could build one. I'm looking to stay close to $3k. My truck is a 2000 F250 lariat 4x4 with 268k miles. I'm installing an S&B intake, 4" MBRP exhaust, and DP-Tuner's F6 chip when I get the transmission work done.

2004 F-250 6.0 Turbo Diesel W/ Torque Shift Transmission. Im having a problem with my Check Gauge light coming on and Tow Haul light flashing on my 04 F-250. I got a Transmission Fluid Temperature Sensor from my local Ford Dealership. They also said i needed to replace the Transmission harness for this application because of an open circuit.
My questions are, Is Mercon SP the only ATF that can be used on the Torque shift transmission and do i really need to replace the harness or just the sensor? I have read up a little on this and so far everything say's drain the fluid, drop the trans pan, swap out the sensor, replace the trans pan (torque setting is 11flbs I believe, correct me if I am wrong, replace with Mercon SP ATF and your good to go.

2002 F250 7.3 4WD Lariat 129K miles ... Brake lights come on when truck is off/no key ...
Ford replaced VSM in Nov. 2012 for this problem
Ford found rubbing wire upon pedal depression and re-routed wiring in April 2015, again for this same problem.
What gives. I'm hesitant to take it back to the Ford house... any theories??
Also, when ignition is in "on" position, transmission and coolant gauge register "cold". Upon starting, coolant stays at "cold" but tranny gauge immediately goes in to "normal" range. Shouldn't it also say it's still "cold"?
