Ford Transmission :: Over Drive Light Started Flashing And Truck Got Jerky Going Uphill - 4r70w Went Out
Jul 17, 2017
One day I was driving my truck 96 f150 4x4 Eddie Bauer edition and the over drive light started flashing and the truck got jerky going up hills. I got home and hooked my code reader up and (p0708) it said transmission range sensor. I replaced that the next day and drove it around town for about 30 minutes and parked it all seemed to good. But the very next day I started down the road and the transmission was slipping very bad after I turned around after a few hundred feet I barley made it back to my house. I checked my transmission fluid it's full and doesn't smell burnt or anything, I double checked the alignment on the neutral safety switch I just installed and it still in line. So I'm thinking my transmission is going out...

Yesterday I had a flashing O/D light come on for about a minute, a quick scan shows a P1747 code indicating a short in the EPC solenoid circuit. Poked around the harness this morning and found this:
I'm guessing transmission fluid shouldn't be there. Do I have to replace the whole internal transmission harness to solve this? How much of a job is that?

2006 F150 Triton 5.4 Motor... It's been over a months journey with fixing this truck....
How it started: had an oil change, a while back, on long drive after, check engine light started flashing as I accelerated up hill so I pulled over and in a while it was ok, but couldn't get on the gas too much, or it would cause that flashy light thing.
So fast forward to now, after driving it with an intermittent miss for a while, was driving it to work and the miss became a shudder, and she stopped going over 30-40, and runs extremely rough.
Steady but loud idle.
Replaced all plugs with motocraft plugs and new coils all around. No change.
Finally hooked it up to a computer and got random misfires, now it's saying
P0174 bank 2 too lean,
But it's bank ONE that's the only side misfiring.
Here are the freeze frame details:
Frame 1 Mod $00
MIL Status Off
Troub Code P0174
Abslt TPS 24.3%
Eng speed 1665
Baro PRS 71 kpa
Calc Load 100%

I have a 2005 ford expedition with 91000 miles, it has the 5.4 w/ the 4r70w transmission.
For some reason when my truck tries to shift into 4th gear, the RPM's climb to approx. 3000 rpms (meanwhile the truck is not gaining speed) and slowly drops down to about 1000-1500. once the rpms drop down fourth gear eventually engages and I can go about my business as normal as long as I do not let my mph drop too low.
If I turn O/D off, the truck drives perfect, minus not having overdrive.
If I come to a dead stop and put the truck in 2nd gear, with O/D on the truck drives great and it has good engine braking so I am assuming that the band is holding.
I took it to a transmission shop to have some diagnostic checks done, they told me that fourth gear was barely engaging and that they would have to tear apart the transmission to diagnose it further, I told them not to disassemble the transmission.
So I changed out the torque converter (which I assumed was "fourth gear") and changed out all the fluid, the fluid looked a little burnt but there was no debris in the pan but there was some silver material on the tranny pan magnet, and installed a new filter. and the problem still exists.

working on a 2000 F-150 (5.4L & 4R70W). the truck was towed to me with the complaint it would not go forward.
I found 6 transmission trouble codes set. I cleared the codes and was able to drive the truck for about 30 miles. It shifted perfectly and had all 4 forward gears, codes did not come back. I parked the truck to check the fluid level (it was full) waited about 15 mins and went to move the truck, As soon as I turned the key and started the engine the CEL came on and the OD light started flashing, the transmission would engage in forward gears but would just chatter when you tried to accelerate.
I checked the codes and found P0743, P0750, P0755, P1747 and P1760 set. I tried clearing the codes again several times and come back instantly when the key is turned on.
I doubt all the electrical solenoids in the transmission have failed at the same time. I suspect the internal connector and/or harness maybe faulty. what is the best course of diagnosis on this? where so I start?

Had a front seal leak on my 2000 F250 V10 with 122000 miles. Since I've towed for years and the tranny had to be pulled I opted to just rebuild the whole tranny. I had problems from the beginning where it wouldn't shift into third and when I took my foot off the gas it would just go out of gear completely and just rev. After I stopped and started over, it would shift fine for the rest of the day.
Finally the O/D stem light started flashing and the mechanic did something to fix it. Since then it has shifted fine but when it went into overdrive the rpm would bump up and kind of slide into overdrive. Left the truck with the mechanic again for two weeks and it's better, sometimes revs and slides into overdrive not every time though.
My problem, besides the overdrive shifting, is it now takes forever to shift in to 4th gear. I have to take my foot off the gas to make it shift into 4th and overdrive won't kick in until 45 MPH. My gas mileage, while bad enough before all this, has now dropped another 2 mpg to around 7.5 to 8. I was thinking about taking it to a Ford dealer for some kind of analysis.

2002 7.3 4R100 ... The truck started flashing the O/D light pulling a 9K lb trailer on the highway.
The transmission codes read were P0705 (Range Selector) and P0873 (bad 3-4 shift - RPMs did not drop).
On the highway, the TCC seemed to lock up fine in 4th (OD button was set to leave O/D ON). When the truck would downshift (not often) then it would sometimes would rev high when it downshifted. It was like 3rd was slipping or it was downshifting into 2nd instead of 3rd. I think it was doing a 4-2 downshift but not 100% sure.
What confuses me is that if it is doing a 4-2 downshift then it would have to change state of both valve body solenoids. Is it possible that it was doing a 4-3 shift but solenoid was sort of sticking? Trans fluid looks fine.
I have read other posts where people had same problem (titled 3rd gear slipping), but they never seemed to resolve the problem in the thread. How likely is it that the solenoid is the problem? It seems to drive fine in 3rd when the O/D OFF button is pressed and O/D is not allowed.

Its a 2004 f 150 5.4 2 wd auto, I think is a 4r70w, when I first start out in the morning I get a trans malfunction on the dash and the od light flashes, if I shut the truck off and restart it goes away for the rest of the day, when it does this the speedometer doesn't work right, vss?

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.

I have a problem with my transmission slipping. It seems to happen most often when I have shifted from park into drive and am going uphill. I don't really notice a problem with it when I am on flats or even at red lights. It can drift backwards for 10-15 feet before "catching."
I don't feel any problem when I am going faster or in higher gears. 1999 Ford Explorer SOHC 6 Cyl 4.0...

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.

My truck makes a horrific screeching sound when it's loaded or pulling a small trailer (2000lbs) up hill. I discovered last night while I had it in drive, if I hold the brake and give it a little gas (like if you were trying to do a burnout) it will make the screeching noise as well. It won't break the rear wheels loose either, which makes me think it's down on power or the transmission is slipping.
My first thought is the transmission, but some searches on this forum describe U-joints or the carrier bearing as possibilities. The previous owner told me he replaced a U-joint just before I bought it, so I'm not ruling that out at all....

So apparently even though the engine light is coming on and off it's not recording any error codes.I tried with my reader, one from Auto one, and then a better one at a local shop, none of them would show anything. The issue is it feels jerky when the light comes on(or goes off). Imagine cutting your cruise control off while it's accelerating and then immediately cutting it back on and that's similar to what it feels like. What could be the cause? I guess I might drive my wife to work tomorrow so I can go by the dealership in Atwater Ca (I'm a bit worried, the one in Yuma, AZ tried to rip me off for three grand).

2000 Excursion 4x4 v10 auto. Pulling the boat last weekend up the driveway from the lake and the truck started smoking under the hood at the top of the drive. Jump out and saw a fire under the pass floorboard. Go the hose and put it out in 30 sec. Thought i blew a trans line and it sprayed on the cat. Took it to the shop and he said lines are good it's not leaking. He said it is possible that the trans over heated and built up pressure and blew it out past the front seal.? What happened or how to prevent it from happening again?

My truck does not go into reverse but thinks all positions of shifter are drive. I had some slippage and changed the filter and oil great for awhile then blame no reverse just forward I was told my torque converter was out I just don't know....

I was towing my 20' boat and had a 4000 lb camper on back going up a grade in 85-90 degree heat when the tranny started dumping fluid. Got to the top and let it rest for 2-3 hours and refilled and was fine for the rest of the trip. This happened last summer. Truck is only driven about 1000 miles a year. I believe this is the E40D.
This year it will run smooth until after about 20 miles and then begins slipping in Drive and OD. Seems to work fine in 1 and 2. It shifts very hard and runs higher rpms before doing so. Slipping then seems to be sporadic and may not slip for quite awhile but it still shifts very hard.

Working on a 2004 E-250 van. [URL] ....
I went through this transmission completely, its back in the van and I get no 1-2 shift.
when I first put it together, I missed the hole in the flex plate for the torque converter stud and started tightening the bell housing bolts down, I heard loud "POP" and realized what I had done. maybe I damaged the pump?
forward and reverse engagement is firm, both give a nice bump when it goes in gear. This tells me the forward clutch is working, but the intermediate clutch is not applying to make second gear happen.
I have done all the easy stuff I can think of, replaced the shift solenoid and put in a new 1-2 accumulator piston. I guess i need to air check the intermediate clutch piston again and make sure its applying. this a 2004 model trans, so it has the new style pump and intermediate piston.

98 ford expedition 4.6 2wd, 4r70w only reverse works. Here's the low down on what happen.
First off the truck overheated a little then was cooled off and coolant added. about a week later it wouldn't go forward so i told my wife to check the tranny fluid it was low barely on the dipstick, fluid was added and she was on her way. this past weekend the truck sherd all 5 lugnuts on the driver rear wheel. fixed that but went to drive it away and the tranny was slipping a little. added 2 quarts to fill and on the way again. 3 days later went to drive it to my dads shop to find out where the fluid is going, its slips again, added 2 quarts to fill just to drive 6 miles.
It drives fine until i get to my destination we have to stop to open a gate, i put in neutral to roll back to open the gate and no forward gears, only revers. i drive backwards to the shop about 300' and the tranny is empty again. looks like the fluid is going into the radiator which i'm sure caused the overheating a couple weeks back. no water is getting into the tranny. I've changed the filter and fluid and radiator, but still no forward gears only reverse. could there be an easy fix, electrical part maybe or mechanical or do you think its trashed and need replacing.

Just finished putting a fresh 460 backed by a (1977) c6 in my '68 ranger and now I'm having (what I believe is) transmission problems. The truck will idle and rev properly in gear but as soon as I put it in drive or reverse the RPM's drop and it dies. I jacked the back end up and put it in both drive and reverse and the tire's spin, but if I try and apply the brake to stop them the truck will die. My suspicion is that the torque converter is locked up all the time. I have managed to get it in gear and give it gas and it'll drive and shift fine, until I come to a stop. My question, what would cause the converter to do this? It's the same transmission and converter that I pulled out a month ago and I never had any issues before...

Last night I backed up out of a parking space and when I put it in drive it wouldn't move. It seemed like the transmission was locked up. What happened? The truck was running fine. It's a 2002 Ford Ranger 3.0 with auto transmission. Getting it serviced? I'm tempted to go to a dealer. What the problem is? Repair costs? The fluid looks good - no burning smell.

I've been making steady progress tearing down the transmission from my 2002 E-150 but have reached a point that I can't continue. The ATSG AODE manual says to "Rotate the shell assembly to align indent with overdrive anchor pin and then Remove forward sun gear." This is the step right after removing the intermediate stub shaft.
Well, the stub shaft came right out but the shell will not rotate, move, or do anything. It certainly cannot be removed. How to get this out?
Background: The trans is being worked on due to a failure that prevented it from being driven and it actually stalled the engine when shifted into any forward gear. It would idle in park or neutral. It would also still allow the engine to run in reverse but the van would still not move. I was able to push it into the garage in neutral.
