Ford 7.3L Power Stroke (1999-2003) :: Flashing OD Light - Code P0741
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.
Ford 7.3L Power Stroke (1999-2003) :: OD Light Flashing - Code P0741 After Replaced Shift Solenoid
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?
View 1 RepliesFord 7.3L Power Stroke (1999-2003) :: 2000 F250 - Auto Transmission Code / OD OFF Light Started Flashing
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.
Ford 7.3L Power Stroke (1999-2003) :: 2001 F250 - Airbag Indicator Light On For Code 47
About a year ago, my airbag indicator light threw a code 47. It did this for about two days, then it stopped. Fast forward to this weekend, and it started again. From what I can tell, it is the passenger side seat belt pretensioner. It could be a coincidence, but my daughter pulled the seat recline lever without anyone being in the seat, causing it to fly forward as if James Bond was ejecting someone through the windshield. The next time I started my truck, it was throwing the code. I tried to check to see if the plug was knocked loose during the ejection sequence. I thought the connector was under the passenger seat, but I don't see any wiring (the passenger seat is manual). My next guess was behind the glove box, but I'm not sure what I'm looking for.
My truck is a 2001 F250 4x4 Lariat.
Ford 7.3L Power Stroke (1999-2003) :: 2002 - P0781 Code / OD Button Flashing
So here it is, I have a 2002 F 250 CCSB, 7.3, 180k, 4R100 Auto (Build date 06/02 so no mechanical diode correct?), 4x4, 4 inch exhaust, Riffraff 6637 Blue filter, with edge evolution (run in STOCK ONLY, just using it for gauges) that has recently thrown the P0781 code, and flashing the OD button. The interesting thing is I haven't noticed any hard shifts from 1-2 or any gear change for that matter. Fluid was changed less than 2k miles ago, was nice and red.
I have read of others having to rev up to 2500 RPM and then let off of the throttle to shift. No such issues here. Drives the same as usual. The only issues I can think of would be a sticky shift solenoid, sticky shift valve, or intermediate one way clutch that can cause this problem, but as it is only a code and blinking OD light and no actual shifting problems I am at a loss?

Had to change the UVC harness on my 2001 7.3. Truck fell out. Trailered it home and changed the UVC harness on the passenger side. Truck is running great, but now the OD light is flashing. Can't read transmission codes, but was wondering if something from the bad harness could have caused this? Any thoughts?

Have a 2003 F350 srw 4x4, 107,000 miles on it. Driving it last night tow/haul light started flashing, hooked up AE got a P0730 Incorrect gear ratio. Truck seem to do ok, cut it off went back out a little while later and the tow/haul didn't flash.... Only issues I've had is when shifting from P to R, it takes a second or two longer than it should and shifts hard when it does but it doesn't do it every time.

Ford 7.3L Power Stroke (1999-2003) :: 2002 F250 - OD Light Started Flashing
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.
Ford 7.3L Power Stroke (1999-2003) :: Rebuilt Transmission Flashing O/D Light With Codes
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?
Ford 7.3L Power Stroke (1999-2003) :: 4R100 Trans Won't Go Into 4th / OD Light Flashing And Occasionally Overheats
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.
Ford 7.3L Power Stroke (1999-2003) :: F350 Leaking Fluid / OD Light Start Flashing
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.
Ford 7.3L Power Stroke (1999-2003) :: OD Light Starts Flashing After Coming To A Complete Stop
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.

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...

2001 7.3 Excursion, full mods in sig line.
Recently started getting a P0720 for OSS on 4-6 pound launches, and the X will lurch and then stall out. It drives fine when I drive like a normal person, it also launches fine at 8psi and up (obliterates the tires in the process). Little curious as to where I should start looking beyond the usual culprits on checking the connector for corrosion and verifying the sensor itself is clean/still good.
Stupid thing drives like a peach everywhere else except the 4-6psi LAUNCH ONLY range. Normal driving through that pressure range is absolutely fine. 4-6 is the only problem child area.
