I have a 97 f150 2wd 4.2. my speedo is working on and off, my overdrive button is flashing and its shifting terrible. I changed the vss in the top of the rear diff but no luck... is there another sensor I should change? or go back and start looking at the wiring to the on in the diff. she has 353k on her and was running great till this.
View 6 RepliesSo I drive a 19 97 F150 v8 5.4 4x4 and while on the freeway I noticed that my overdrive button was blinking on the shift lever. The truck wasn't driving any different than usual, so Im just trying to figure out what this means.
View 1 RepliesI tried the test mode (hold trip reset and turn ignition to run) this revealed that the needle for the speedometer does sweep from zero to max and back, could it still be the cluster? Is there something I am missing? FWIW the odometer lights up but does not work and all other gauges seem to be functioning correctly.
View 10 RepliesI'll start with truck specifics. 2001 Ford Expedition, 5.4, automatic, 141,000. We just got the truck 4 months ago, second owners. Seemed reasonably maintained, other than Ball joints.
This afternoon, my wife and I were cruising along on this warm 90 degree summer day, out running some errands and having a good time ( we both had today off) about 70 miles from home. When we pulled into one of our spots, I noticed a few drips heading in the direction of under the truck. i simply thought the AC, which had been running full blast for an hour, was dripping, not a huge deal. didnt think twice, a few drops, no biggie. We ran a few other errands, then got back on the highway going 70 MPH. I heard a low moan at 70 that would come anbd go, I thought I may have had a tire howling on the road or possibly the start of the shifted belt. Noise was intermittent, but went away after a few minutes of driving. another mile or two down the road, I noticed the rear window seemed oily. Suddenly, things began to click, oil blow on the back window, funny noises, drips, something was leaking.
My eyes darted to the gauges, everything was holding up as i made it to the nearest exit another few miles away. As I hit the exit, i noticed the overdrive on off indicator flashing at me on the shifter stalk. I roll to the stoplight at the end of the ramp, suddenly, the tranny slips. There was no slipping on the highway. the truck did get a grip and get me from the light a few hundred feet ( there was a line of traffic behind me) to a parking lot where I could stop and inspect. as i shut it off and peeked under, fluid was pouring out of the bellhousing of the transmission. i called pops, he brought down the truck and trailer and we winched it on, dragged it home.
So, now the truck in in my garage, on the lift (yes, im spoiled) and I'm surveying the damage. oil leaks seem to be directed only from the bellhousing area, other places only have blow by residue on them. Fluid is a little dark, but not burnt smelling, and within tolerance. I see darker fluid at work when I do transmission flushes all the time.
So, now the questions. First off, I would be guessing that the front pump seal decided to go out, does that sound correct to you gentlemen? I'm going to start digging in on removing the transmission tomorrow, and hopefully get it out by the weekend. Also, from the fluid condition, do you think I got lucky, or do you think I did damage to the transmission?
As for knowledge and resources, I'm a mechanic, I do mostly brake, suspension, exhaust, and maintenance work (oil changes, tranny flushes, other stuff like that) so I do have a decent knowledge base, and while I have swapped transmissions before, I dont have a huge knowledge of tier inner workings. I do have access to a scan tool, and other diagnostic instruments, but as i stated before, not a full working knowledge.
Last year I bought a used '99 F350 w/ ~$135K miles on it. I later noticed that when I pressed on the Overdrive button (automatic transmission) which is on the steering column gear change lever, nothing happened. The overdrive light did not come on and the gear did not change to overdrive.
View 11 RepliesI just bought an older 1995 Ranger XLT 4.0 I was told that the truck is stuck in overdrive. The overdrive light is not working and the button does not respond. It shifts smooth but run away with it's self. It is not shifting a lot going up hill and curves.
I got a diagnostic and it did not show codes. I was told the trani has had an oil change and filter with no metal parts in the oil. Since the overdrive switch is know for a short in the steering column maybe when they looked at it they did not know what they were doing.
I am driving it only once or so a week. But don't want to hurt it. A friend did the first work and had it diagnostic done yesterday.
2002 Escape. The over drive deselect button stopped working on my wife's escape. Is their a fuse other than the box under the hood? Transmission was rebuilt not too long aga and has been running fine till the other day.
View 2 RepliesI have a 2001 F250, 5.4, 4X4. My ignition key stuck in the start position and when I pulled it back to the run position, everything seemed ok. As I started down the road, my speedometer stopped working and my overdrive light was flashing. Also my turn signals had stopped working and my A/C clutch didn't engage. Figured I burnt a fuse. I looked in both the under dash and power distribution box and all seemed well. I checked the fuse for the turn signals/flasher and it was fine. The flashers worked. Thought I might have fried something so I replaced the ignition lock and switch. Also my service engine light came on throwing a code for the vehicle speed sensor.
Looking for solutions on this forum and the internet, I learned that the turn signal switch could have gone bad and the VSS sensor is on the top of the rear dif and an easy fix. Well replaced the sensor but nothing changed. So I went back to the fuse box. Examined every fuse, big and small and I found a 10a with a small space. This was #24 under the dash. From the manual, "#24, 10A, A/C clutch, Blend Door Actuator, Trailer Tow Battery Charge Relay Coil, Four Wheel Anti-Lock Brake System (4WABS), Turn Signal." Replaced it and everything went back to normal. Turn signals work, A/C clutch works, no flashing overdrive light and speedometer works. All from a 10A fuse. If you have any of these symptoms examine all the fuses carefully. There's a 20A fuse for turn/hazard lamps and this other one buried that's only 10A.
The overdrive light is flashing but not all the time. What does this mean?
View 3 RepliesMy 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.
Here is my issue. I have a 2000 e350 7.3 the overdrive light is flashing, the speedometer and the odometer isnt working it also shifts hard, i changed the vss, the vss plug, range sensor, and alternator. still acting up. also all the fuses are good.
View 8 RepliesMy father-in-law has a 01 F 150 4x4 with the 4.6 automatic and his overdrive button will not disengage. Is there a fuse or something on the tranny that he can look at to get it to work?
View 7 Replies2000 5.4 4x4. 104k miles. Extended cab. Heres the issue, when you're at that spot on a slight upgrade and the tranny should down shift out of overdrive it will downshift kinda hard. Sometimes it does this and sometimes it wont. Its driving me nuts. I thought maybe change the fluid and filter and see what happens, but a tranny guy that I don't know from the other guy said dont waste your money its more than likely a broken spring behind a piston. I put a new motor in this truck about 10k ago so I can wrench. It did this before the motor swap too.
View 10 RepliesF150 has the 5.4L w/ the auto. 59K on the ticker. This "spuddering" type problem only happens when in overdrive. Mostly highway and when starting to pull up small hills. The symptom is a slight jerking and "spuddering" feeling. It goes away with more rpm's and some acceleration. I've tried injector cleaners and 91 octane just for grins, nothing works. Is this a possible COP issue?

176k miles & original engine/transmission.
What does this mean?
My overdrive light is blinking off and on. When I accelerate normally, the truck starts stumbling? (don't know a better word) some, sort of like a clogged air filter or fuel filter. I am going to take it to a transmission shop because its a little beyond me, but don't want to get ripped off.

View 1 RepliesSo 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?
My overdrive recently stopped working on my 2003 F250 and I also noticed that the light on the shifter is not lit indicating that OD is off. When I push the button on the end of the shifter the off light doesn't come on like it used to. I have noticed that sometimes after I shut the engine off and re start it will go into overdrive as normal but the button will not light to off or turn OD off when pushed.
I have been reading about chafed wires in the column where it comes out of the shifter but most guys are saying their off light is blinking and their trucks will not come out of overdrive when the button is pushed. My question is, should I check for the chafed wires in the steering column? The transmission shifts great , just not going into OD all of the time and its killing my fuel mileage turning 2900 rpm at 65 mph.
My 2002 f150 blows the overdrive fuse (#29) every time the overdrive tries to engage. Could it be the overdrive switch? Where is that switch? Could it be a speed sensor? Truck has an automatic transmission and a 5.4 engine.
View 14 Replies2003 F150, 5.4 FX4, overdrive light flashes. Took to a shop they said overheating issue, but I don't understand if it is a overheating issue why does I flash at 4 in the morning when I leave for work fter sitting all night and why does it stop when I do over 70 on the highway.
