Ford Super Duty (1999-2016) :: Shifting Not Right - O/D Flashing
Jan 4, 2015
So I was driving earlier this morning and I noticed my overdrive light blinking, I didn't think much of it since I know the multi-function switch is bad and I haven't had time to change it yet, but a while later I was accelerating and just before it would shift from 2nd to 3rd it went to neutral. I played with the shifter a bit and found that if I shifted the column to 2nd I could drive in second, not a problem being only 3-4 miles from home.
I did a bit of digging and found I had blown the OBD2 fuse and saw a few people mention fuses as a possible shifting problem, Replaced that and still having issues. I have found that if i start out in drive I can shift into 2nd on the column then at the proper rpm put it back up into drive for 3rd and 4th. I just had the transmission re-built 400 miles ago and it is under warranty but I want to make sure it's not a computer or some other sensor before I call and bitch to them. I saw a couple posts referring to the shift solenoid but the problem was different.

Im having an issue with my 2000 f250 7.3 diesel. 4x4. The od light is flashing and the tranny is kind of jerky when it shifts. Also my truck won't go into 4 low. (I have shift on the fly) and every time I put it in park my truck revs up to 2000 rpm for a few seconds. I do have a ts 6 pos. Chip with can tunes on it. And I have already replaced the IPR. It does it even in stock setting.

Just got the transmission rebuilt in my truck and other then shifting hard sometimes it has been doing great, Hooked it up to the goose neck this evening and everything was fine then went to back it up and pull it forward and after a short distance the od light was flashing and when i ran a check on it it was p0720? The transmission has less then 1000 miles on it?!?!? 1999 Ford F-250 7.3 Automatic....

2006 E-350 Dually Ambulance Chassis with the 6.0... Approx 125000 miles.
Recently, the truck started an issue. its an every once in awhile thing but has been doing it more recently. The OD light will start flashing and the vehicle will start to have clunking in the tranny and start shifting rough. ABS kicks in making it hard to stop. Once you turn the truck off and back on, Its fine until it does it again. Im connecting to a scanner tomorrow to see if i get any codes.

I have a 97 F350 5.8 with E40D trans. I bought the truck with it shifting hard thinking maybe a simple filter/fluid change would fix it. It may have worked a little but did not fix the issue. There were 3 or 4 codes that I have already cleared up with new parts. I am still getting a 327 (something with EGR?) and 629 (Converter clutch control circuit failure). These show up in KOEO and KOER self test. The O/D does not flash ( bulb does work).
Parts that have been replaced: VSS, MLPS, new connector going into solenoid pack (tabs were broken), TPS. Removed the trans wiring harness and there is no damage or loose connections. When I replaced the solenoid connector I noticed there was some trans fluid in the connection. I cleaned it the best I could and reinstalled with dielectric grease.
The truck runs fine and shifts in and out of every gear fine its just shifting hard. If I unhooked the battery it will shift perfect for 5-10 minutes but then the hard shifting returns.
The only other thing I can find with my research is maybe the solenoid pack needs replaced. I figured if I take it somewhere they are going to want to rebuild/replace transmission. It seems like it can't be something very major since it will shift fine when reset...

I just traded in my trusty, never had a single issue 2008 Ford F150 with 53k miles for a 2008 Ford F350 with 112k miles. I figured the extra miles were okay, because it is a diesel. I purchased the truck to pull a 31’ 12k lbs when loaded toyhauler, and I have a 14K weight distribution hitch.
Just in case this makes a difference, here is some background information. I have a 2008 Ford F350 XLT 6.4L CrewCab Long Bed. Before purchasing it, I had Ford do a performance and safety inspection. Everything came back clear, so I bought it. The day after purchasing it, I changed all the fluids for peace of mind, ie. rear diff, transfer case, transmission, motor oil & filter, fuel filter, and radiator fluid.
Here is the problem. Occasionally, the 4x4 Low light will start blinking/flashing. Sometimes it will only flash once or twice and go off, other times it will flash for 15-20 seconds and then go off. There is no pattern to when it happens other than it seems to do it mostly when slowing down or breaking. It is very sporadic. I don’t drive very far for work, so I can go an entire week without seeing the light come on, but if I hit the highway for 30-45 minutes, the light will eventually turn on.
When it flashes, occasionally, I get an RPM increase…almost like it’s trying to engage natural or shift into 4x4 low at highway speeds…which causes me concerns. I took it to Ford and after 50 miles of driving it around, they could not get the 4x4 low light to come on. They said they pulled codes but there were none to pull. They reflashed the PCM and charged me $99 to not fix my problem.
I can shift into 4x4 high and 4x4 low (with the window rolled down, I can hear the shifting from 2wd to 4wd high and then to 4wd low and back to 2wd), so I don’t think it is a blown fuse or the control module. I removed and cleaned the wire connectors to the shift motor on the transfer case, and that didn’t fix it. I was thinking about replacing the rear diff abs speed sensor in hopes that will fix it. I think that maybe it’s a wiring issue, which I wouldn’t even know where to start.
I was getting 14 mpg before the reflash and after, I am now getting 8 mpg. Does this seem right? Or is there a learning period after a reflash before my mpg gets back to normal.
Also, the automatic 4x4 drive doesn't work. I don't think its holding a vaccum. I don't think it is related to the 4x4 low light coming on when I am doing normal driving. I can use the lockers to get 4x4 to work correctly. Infact, Ford is the one that told me the auto doesn't work.
Edit: I also noticed that if I flip ON any of the upfitter switches (ie AUX 1, AUX 2, AUX 3, AUX 4) the 4x4 low light will flash constantly until turned off. I currently don't use any of the switches for anything.

I have a 99 7.3 F350 with 5 speed manual with over 300,000 miles. Grinds bad shifting into 3rd, and nothing happens in 4th. I think it is a S5-47-ZF. Is a 6 speed manual comparable to bolt up to bell housing?

On dads 04 f350 the 4wd first wasn't shifting to 4lo. Would do 4hi and 2wd fine. Then motor on t-case went bad. Replaced motor 2wd and 4hi still good still no 4lo. Then just 2wd so we unplugged t-case motor and power probed motor got it to do 2wd, 4hi, and 4lo. So we thinking bad dash switch but power probed it and its working fine. So we r thinking VP4C3F-14B128-A/ chassis computer bad just behind/above glovebox. R there any test we can do to confirm its bad? We called local junk yards to see bout getting one, nobody had one. If this is indeed bad where is cheapest get one? What all years use this certain chassis computer??

The other day I was driving to work and I noticed my truck wasn't accelerating right and the transmission wasn't shifting into high gear. Its almost like the truck went into neutral around 2000 rpm. What the issue could be? I really don't want to replace my transmission if I don't have to.

I know this has been done to death, but on my '08 F250 XL I can't seem to get the truck to enter into the programming mode to program some fobs to it. I've done the cycling business and the best I get is a flashing light on the dash of the truck with a little lock on it, but nothing else. Can you not program the XL? Is there a major step I am missing?

1998 F-250 LD 4x4 463,000 km.
My truck begins to flash the OD light after driving about 10 km. So I borrowed a friend's scan tool and got a P0503, and P1500. So having been pointed to the vehicle speed sensor, I connected TORQUE and watched closely vehicle speed. Driving at a steady 80 kph it will jump rapidly up and down, from about 72-92, while the gauge in the instrument cluster reads a calm and steady 80.
Which sensor and wiring do I need to inspect? Rear diff or on the back of transfer case? Oh, and the ABS light is NOT on.

2000 F250 V10 Auto/Rebuilt Tranny... This weekend, I noticed my truck wasn't shifting at lower RPMs like it has been. I'm not hitting much higher RPMs per shift then normal. Very soon after, I get a "Service Engine Soon" light and my "OD OFF" light on my shifter handle started flashing.

1999 f-250 7.3 diesel. Speedometer doesn't work and neither does the odometer, the ABS light stays on and once you start driving the OD light starts flashing and the truck starts shifting weird. I've changed the rear ABS/VSS sensor on the diff and the OSS on top of the transmission at the tail end. Still no luck.....

I have the dreaded flashing O/D light on my early 99 F350 7.3 4x4 auto. The only one's that seem to be consistently recommended are Snap-On or AutoEnginuity.

I have a 2012 F-250 ccsb lariat and the shift from 3 to 4 seems to be a bit prolonged as if the converter is slipping and wont go ahead and push it into 4 gear. Also it will want to downshift from 3 to 1 and feels like the car behind nailed you. I have read that the early 2011 had some of this problem and the dealer reflashed the tcm and it did not do much good but as mine being a 2012 mine should have been flashed with the lastest tcm flash from the get go?? Egr fell off and am running Kory Willis tunes through ez lynk so the stealership is probably out of the question. I have also read that changing a couple solenoids( dont remember which ones) will fix the problem.

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.

I bought my 2011 F250 FX4 about 2 months ago. A little about the truck: 6.2 liter gas. XL FX4. Manual 4x4. 6 speed auto. Supercab. Long bed. 42,000 miles. (1,000 of them mine.)
Until yesterday, the truck has performed absolutely flawlessly under all conditions. Then, randomly, I had what felt like a "missed shift" as I was leaving my dog's veteranarian yesterday. I pulled out onto the highway and as the truck attempted to shift into second gear, it didn't "catch" second. The gas just revved up and I had to take my foot off the gas pedal and put it back down to get second gear to engage. Most of my driving is stop and go around town and this has only happened once in probably well over a thousand stop and go situations. Should I be worried or was it just a fluke?
Also, FWIW, I did plenty of stop and go driving today without a single problem.

I just got 03 f250 with 6.0 and when shifting has a weird surge/lag thing happening. Reminds me a little of the old 7.3 surge when it was just started on a cold day. Seems to be worse in higher gears.

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.

I recently bought a van that has a hard shift problem. It is a 1995 E350 with a diesel. If I take off from a stop without babying the throttle, the shift from first to second is very hard. Second to third is hard but not as violent. What might be happening?
