Ford Ranger / B-Series :: Erratic Shifting And Flashing O/D Light
Aug 29, 2016
I have a 2003 Ford Ranger, recently I had the heater core fail. One thing that happened during the heater core starting to leak is the "THEFT" light came on brighter than normal and no longer flashes when the truck is off. Also when the theft light started acting up the O/D OFF light came on and would not shut off. If I pushed the O/D off button the Theft light will go out and then come back on after the button is released.
After the heater core was replaced the lights stayed on as described above. Every once in a while the O/D off light would stay off but then come on later. No really problem besides the lights and O/D off button not working. Now today the O/D off light started flashing and the truck kept shifting in and out of O/D.
I'm leaning towards a speed sensor issue. I'm going to check and see if there is any codes tonight and will post my results. One other thing that happen with the heater core leaking is the "CHECK ENGINE" light came on because the O2 sensor was shorted out. Have the O2 sensor now and plan on replacing it while I trouble shoot the erratic shifting in and out of O/D.

I am having a problem with my O/D light flashing and my truck shifting hard. Just started out of the blue. After reading a few other topics, I am hoping it is the VSS. Now if only I could find the dang thing. Looking for a diagram, or detailed description on where it's at?

I have a 98 Ranger, 4.0 automatic 4x4...I just replaced the upper and lower intake gaskets and after fumbling with the pug wires to finally get them in the right order, I suddenly find my OD light flashing off and on, and the tranny slamming into second, and once in top gear can feel the OD popping in and out? From my reading here it looks like a pretty common problem, but the solution isn't as clear...
The vehicle set for about 3 months while I healed up from a injury, and and was working just fine when I parked it...due to the blown lower intake gasket. I am thinking I have a vacuum line not connected or wrongly connected...or some kind of over looked item, but I can't spot anything...should I get a code reader and go from there...

My speedometer is erratic, not reading correctly, and the trans is not shifting right. It gets up to 3000 RPM and I have to back off the throttle to make it shift to 2nd. Then after driving a while everything starts working right. Next time I drive the truck it does the same thing.

I had a problem with my truck about a week ago with the O/D light flashing and the ABS light on, I ended up taking the truck into my mechanic and he troubleshot everything and ended up finding out my trucks computer was fried. NOW, I want to know if the fact of me putting 31 inch tires on my truck was the reason for this happening or would it have been something else??? Because I really want to put the tires back on but I am afraid it might "burn" my computer again!

My 2002 Ford Airbag light is flashing 46. I believe this is the Drivers side crash senor. I am repairing the left front fender and left front wheel suspension. I have replaced the two air bags and airbag control module. Where is the left front crash sensor?

2001 Ranger 3.0 liter has developed a transmission casualty. I was driving along at 30 mph and the transmission went into "limp' mode with O/D light flashing and truck will only barely creep along with high engine rpm. When I got the truck home I was able to retrieve a p0720, output shaft speed sensor signal fault. I had hoped that replacing the sensor would solve this casualty.
Of course this was not the case. I have read all the posts I can find for this particular fault and realize that I must electrically trace the continuity of this circuit and also ensure that it's not grounded. I have been unable to find the needed wiring diagrams or pin out information.
Before I have to try and blindly start pawing through the connectors I'm looking for the pinout for the PCM and perhaps the bulk connector above the engine between the PCM and the transmission wiring harness. I am also keen to hear of any diagnostic tips that I may have overlooked.

I have a 99 Ranger, 3.0 xlt 2WD Automatic 5r55e(???) tranny (i know its the 5). I have the o/d off light flashing. It comes on when fluid gets to op temp. When on it shifts hard into 2nd and hard when it downshifts. No slipping. I have had the truck in the tranny shop for 3 weeks, owner said he re built valve body gasket (didnt work) tried 3 diff used tranny's (didn't work) or so he says. He said it needs to be rebuilt.
I have searched up and down for what it could be, there is so much out there, it only confused me more. If i have to rebuild i will, i think the tranny shop was pulling my leg (for more reasons than mentioned). I have a check engine light on nothing to do with tranny...there is a tranny code, he would not tell me but i will have it checked. Been told could be throttle position sensorl, speed sensor cracked case and a million other things. I have some mechanical abilities, (not too much w/ tranny's) but i can change a few simple sensors.

I have posted on here before about this very issue, thinking it was primarily the transmission. In additon to a hard upshift/downshift (it almost feels like getting a little "kick" from behind while in the truck) I was getting a flashing O/d light, etc.
Since then the tranny died. No shifting at all. I was able to find a usable replacement from another truck (the guy sideswipped a pole, and decided he was done with it, as he tweaked the front frame slightly), which was working fine (before the accident).
I swapped the units out (trans and T/C), and the truck has life again! No flashing O/D light, nice power, and good gas mileage (I went from pre-failure 15mpg to 20mpg now).
However, the kick has never gone away.
So, what next? How much "play" should there be in the driveshaft when the vehicle is parked? I can move it a little bit. Should I consider servicing/replacing the U-joints? Or should I now suspect the rear diff to be the culprit, and how can I best determine this?
Also, can you switch out one rear end for another? If you can, is there any any paricular one that is better to use for towing/hauling as opposed to, let's say, off-roading or city driving?
As for the vehicle in question, it's a 1995 Ranger XLT extended cab with a 3.0V6 and auto trans. I believe it's supposed to have a limited-slip diff, but how do I determine this?

My 3.0 with 216k miles has developed a rough idle and it progressively got better with new parts and cleanings. On startup it revs up to 2k then back down to 600. If I let it idle for about 8 or so minutes my Check Engine Light starts flashing. If I drive about for a little bit it stops and is just fine.
While the light is flashing I get codes P1000, P0305, P0306, and P0316. Which are OBDII Monitor Testing Not Complete, Misfire detected in Cyl 5, Misfire detected in Cyl 6 and Engine Misfire Detected on Startup (First 1000 Revolutions) respectively. Any other time the truck runs like a dream. Gets 20 city and 29.5 highway.
I cleaned my Mass Air Flow, replaced my Idle Air Control, SeaFoamed throttle body and vacuum lines, brand new coil pack, new wires, new plugs, new fuel filter, I've only ever run 91 octane, Chevron with Techron goes in at every oil change and B12 every other and I just ran 3 bottles of Lucas fuel injector cleaner.

Its a 1994 with 4.0, automatic, 4x4. Running fine, parked it, a week later I'm getting a bad but sporadic miss that according to the stealership is the 3 cylinders on the right bank dropping in and out. Driving down the road you can feel them drop out and when they come back its a kick in the pants like a turbo kicked in.
Shop says wires are good, plugs are good, and then lost me when they started talking around in circles and not making much sense.
What could make 3 cylinders all on the same side of the engine drop in and out? This wasn't anything that slowly came on. Fine one day, crap the next. The only thing I did prior to was replace the IAC because it was idling high, it was cruddy inside, and it looked like it was original. It was running fine after that till this issue popped up out of nowhere.
Mileage was claimed to be 178k but I'm beginning to suspect it's probably 278k.

On my '91 last week I was driving on the highway about 60-65 when all of a sudden the speedo dial started climbing to 70-75-80-85 and past. The odometer seems to be working ok? Still when I drive it still operates in the same manner. It never bounces around or falls back. The needle is sort of stable such if I maintain a speed the speedo will maintain even though it's incorrect. There is a slight wavering of the needle meaning it's not as stable as it use to be. With the odometer working I was wondering and don't know. Does the cable drive the needle or is it electrically controlled? I'm thinking of grabbing another instrument cluster it that is the problem, I'd like to know more about it and understand how it works so I don't just throw parts at it until it's fixed.

My o/d has started shifting in and out at speeds over 50mph. It looks like it happens for the tiniest changes in engine loading. A windy day plays havoc and mild inclines. Sometimes the o/d light starts blinking until I switch off then operates normally. Extended warm-up driving seems to work. I've been told the rear axle speed sensor may be going bad but I have no confidence in the advice. I am driving an '02 ranger, 3L flex fuel, 2wd and just went over 100k. The atf is at the correct level but the fluid needs changing in my opinion. There are no engine codes.

I have a 2001 Ranger edge edition with extended cab, 3.0L engine, auto tranny (I believe it is a 5R55E) with 95000 miles. I am currently having some rough shift problems going from 2 to 3 and 3 to 4. I had the transmission fluid exchanged and it solved the issue a little bit but it hasn't gone away. It seems to rev up a little then shift real rough. I have read hundreds of threads that talk about the Valve body gasket blowing out on these trucks so I was wondering if this description matches that fix (The OD light does not flash when this happens).
I had to have the PCM replaced right after I bought it to get the emissions to pass (codes wouldn't set) and in the process cleaned all my ABS sensors, replaced my Speed sensor on the rear differential and replaced both rotors.Are there some home diagnostics I can do to narrow down my search for the problem? Also, on a different note, my father has an 03 with the 4.0L SOHC in it and it seems to get a heck of a lot more get up and go. I understand it is a larger better engine but what I am experiencing seems very sluggish for any V6. Could they be related? Might it just be a fuel filter?

My 2.3L Ranger experiences a drawn out 2-3 shift but only does it once in a while. On my drive to work it might do it at 1 of 10 stop/go and the other times it's perfect. It really seams to do it more when it's cold???? I know it's an electronic shift trans so my guess is because it's intermittent it's getting a false signal from somewhere - maybe? All of the other shifts are fine, it just happens 2-3. It has the correct fluid in the trans and is new.

Been awhile since I've been able to post but I've got a serious issue with my 2006 Ranger XLT 4L V6. So last night about 2 miles from home my check engine light started flashing like it was a at a rave and my engine wasn't acting right, also had the STRONG odor of raw gas, no other lights from the dash, no fluids leaking, oil was good n nothing in radiator but coolant. Was able to baby it to my current home but all my tools are in storage so had to wait to get my ODB scanner to see what's up. Scan came back as 'cylinder #3 misfire' & 'O2 sensor reading rich'.
Go cylinder #3 spark plug out and it were fouled bad. Got ride to the store and got a whole new set. Got back n got'em changed and fired ut up, idle still rough and check engine started flashing again and white cloud coming from exhaust pipe and STRONG odor of gas. Check and now have 'multiple missfire', 'cylinder #2 misfire' and 'cylinder #3 misfire'.
Shut it down go and double check ALL spark plug wires are connected and TRY to start, get about a turn n a half then starter spin. Try again and the engine won't even turn over. "Great I've seized the engine!" Was able to put a socket on the crankshaft pully and manually turn the engine over "whew didn't seize the engine", did this a couple of times and tried to start, was rough but eventually it fired up, still idling rough and again check engine light flashing, while it was running I pulled one plug wire at a time from the coilpack to see/feel the lighting and there was spark for the 3 I pulled, didn't affect engine idle.
Run codes and 'cylinder #3 misfire', so now that the engine is was warmed up I pulled out my ohm meter and started checking wire resistance. Cylinders #1, #2 were at .012, #3 was .011 and #5 was .009.
I've figured that the raw gas is due to cylinder #3 not burning and just pushing gas into the exhaust. So to the brass tacks, do I invest in a new set of wires? Or could it be the injector being stuck open and just flooding the cylinder? No when I originally pulled the #3 plug fuel did not spill out. Haven't pulled #3 again due to it being May in Arizona and had to take a break. I'm going on the assumption that the engine wouldn't start after a short run do to "hydraulic lock in cylinder #3", my manually turning the engine over cleared this and allowed the engine to start.

Brother in law has the above truck with shifting problem. On a cold start, pulling out of the driveway, it will get to about 3-4000 rpm and will slam into gear. Sometimes its worse than others, but is consistant. Once it warms up, the problem goes away for the most part.
I've researched a little online and have found a few people mention the 1-2 shift accumulator (servo...?) and was wondering if any of you have ran into this or have replaced one on the A4LD.
And if you have, which servo is the 1-2 shift? I think there are 6 of the little suckers in there. Anyway, all i've done so far is fluid and filter. Old fluid looked/smelled fine.

I have a 2002 3.0 with the 5R44E. I don't like how late it shifts into 5th gear. Is there a way to make it shift into 5th at 45-50 instead of 55? I feel like I have to let off the gas half of the time to make it shift and I don't have a heavy foot. If anything, driving with a light foot seems to make it shift into 5th later.

Here's my issue: My Ranger has been running like a dream until yesterday.
I took off on a parts run for my sons Ranger. I got to a stop sign and as I stopped, it started missing and barely running. I nursed it back home and checked the flashing CEL. It was giving me a misfire on #3.
Since I had been planning on changing the plugs and wires, I dove in and got it done hoping that was the cause of the misfire.
Started it up, same thing. I went to the next obvious item: coil. Replace it, still running like crap. Gave up for the night.
Today, I thought I would dig in using the tips here on the forum. Did the spray down...no errant spark anywhere. Tested fuel pressure: 65psi no drop in pressure on acceleration.
Started pulling wires off the coil one by one. Four of the wires resulted in running worse. 2 had no effect. #3 and #6. The coil was producing plenty of spark on all 6 ports.
At this point I was sure it had to be 2 bad injectors. Since I couldn't get injectors tonight, I moved them around after cleaning them a bit and tried my wire test again. The problem stayed on the back 2 cylinders!?!
I tested for voltage on the back injector plugs and I am getting voltage. I also used a stethoscope to listen to all of the injectors. The back 2 seem to remain silent. I have also unhooked the battery for 20 minutes to reset the PCM. Still missing and running rough....
Here's a list of what I have done:
Autolite Double Platinum APP5144 plugs. .062 gap
Autolite Pro Series wires #97051
BDW E97P Coil
New air filter
What should I do next? I really don't know where to go next.......
