Ford Transmission :: 2006 Expedition Converter Stall Speed?
May 14, 2015
Specifically for a 2006 Expedition 4R75E . What the stall speed of the converter for this truck is supposed to be? The reason I ask is that the converter seems rather loose. At any point during acceleration the converter will allow the engine to rev up to 2500 RPM, depending on how hard I press the gas.
During normal (for me) acceleration the engine will come up to 2000-2200 rpm and just hover there through all 3 gear changes, then when the vehicle is up to speed and I let off the gas, the converter will lock and the rpms will settle down to something less than 2000 (assuming I'm not going over 75mph) if I press it a little harder, the rpms will come up to about 2500 and just hover there through all the gears, then lock when I let off. the only time a gear change will result in a lower rpm is if the engine is spinning over 2700(ish) rpm.
I'm not sure there is a problem, I'm just curious what the stall speed is supposed to be. if it is supposed to be a 2400 rpm converter, then the behavior makes sense, but if it is supposed to stall closer to 2000, then I'm thinking it might not be working as designed. I've tried to find this on my own, but I don't know where to look.

My 2006 expedition surges very slightly while cruising under very low throttle. Usually most noticeable at 60-65 mph with no headwind.
Took it in and had my mechanic check it out. He confirmed the slight surge and said it felt like the torque converter was locking and unlocking. No codes or pending codes were found related to the power train.
Abs light is on for a bad rear wheel speed sensor. Code for right rear. Checking the sensor showed 3 ohms for right, 5 ohms left ( left is less than a year old on a new wheel bearing.)
Initial thought was the bad sensor is giving bad input confusing the pcm/tcm. But the condition remains with the sensor unplugged.
Driving down the road watching the tach, it does appear that the converter is not staying locked. Condition goes away with more throttle. Motor runs smoothly otherwise with no indications of misfire. Plugs have 50k miles on them, as does the transmission fluid. Fluid is red and smells fine. Never gotten hotter than 210 by the gauge in the pressure port.
Why would it lock/unlock at very low throttle, but lock tight with more throttle? Tps flaking out? Throttle body motor getting twitchy? Can I pull my popup to the hills this weekend?

I have a 2002 7.3 with the 4r100 173k miles. If your nice to it she drives fine, but if you get on it the torque converter will slip/stall kinda revs up like 300 rpm then slams really hard between 1st and 2nd. Other gears work fine. I've only had it not happen like 10 times since I've owned the truck ..... I don't really beat on it except for towing which I'm starting to do a lot of. Wondering if putting a new stock torque converter in it is worth it.? Not gona blow the bank on a TC unless I'm putting a brand new trans in the truck. Which I don't think it needs in the near future.

Having a problem with my 2000 Expedition AWD/4WD. When I'm braking to a stop, there's a metallic clicking coming from my LR wheel. Doesn't matter if brakes are applied or it's rolling free. Starts at about 8 mph and stops at around 2-3. Had a broken parking brake cable, but clicking is still there after replacement. What's next? Wheel speed sensor, perhaps?

My 2010 Expedition Limited AC seems to be stuck in the highest fan speed setting. Changing the setting on the panel control do nothing to change the speed. But you can adjust the temp and it will respond. It is a dual control unit. When I try to turn the system to off completely it will go to what I believe is the vents and stay on full blast. If I turn the truck off and on again the whole system remains off until I turn it on again. The only way to turn it completely off is to turn it to off mode and turn the truck off.

Vehicle 97 Expy, 5.4 XLT 2x4, air leveling and tow pkg.
Situation: installed TransGo SK E40D spring kit to cure 1st to 2nd hard shift. It did the trick and shifts great up to a point.
Issue: Now after replacing the springs, any and I mean any added load (mild incline, lane change) while in OD it will downshift, won't shift up unless going down hill and I'm sucking gas. 1st-3rd is great, but it will not stay in OD to save its life.
I believe the cure is to reinstall the old OD springs, but I don't know which set that is in the accumulator body? I also could be wrong and it may be something else.
Update: found the instructions, need to know if the 4th Accumulator piston is OD?

I just found out there is no dip stick/fill tube for my 07 Expedition 6spd 6R. How to refill after service without using a flush machine. I also can't find any spec sheet on how much to refill or how to tell when it's full.

My wife drives a 99 ford expedition, 5.4, auto, 4x4, Sunday I am driving it and it wont upshift from 1st to 2nd unless I let off the gas or let it run up to 4000rpm. I have cel and blinking OD off light. I pulled the code and got a p0755 shift solenoid b. That is really the only symptom, the other shifts seem fine.
1st question, which transmission do I have? I believe it to be the 4r100, the pan has a "notch" in it. Looks like this... Fel-Pro TOS18714 - Automatic Transmission Gasket | O'Reilly Auto Parts
2nd question, if it is the 4r100 is there just a solenoid "pack" and not individual solenoids to replace? I found these...PowerTorque- TE140 - Solenoid | O'Reilly Auto Parts
PowerTorque - TE141 - Solenoid | O'Reilly Auto Parts
3rd question, what is the difference between the pwm and non pwm?

I have a 2007 F150 It will stall out when I go over a speed bump. It has happened several times and getting worse. No codes stored. It will also skip between 40 and 50 mph.

Reverse works great....engine revs and barely pulls in drive. Not sure yet if it actually changes gears. I am planning on replacing tranny. I have a few questions :
1: Could it be something more simple like a selonoid or ???
2: What all trannys will fit? this is the 2wd 5.4 liter xlt ...

I have a 2006 Ford Expedition that runs perfectly with one exception, It will shut off all of a sudden. I can be driving down the highway or in town and all of a sudden it will just stop running. This has happened twice in the past six months. So far I have been able to get to the side of the road safely.the vehicle will immediately start and run perfectly as if nothing has happened. No error codes.

I have problem with my Ford F-250 7,3 diesel SD from 99' XLT transmission 4r100 . I have changed torque converter and now something leaks between transmission and this converter. What can it be? Is there gasket which must be changed ? I didn't notice anything wrong with it.

Engine' smooth and parameters good . However will drive in low and 2 nd gear approximate 25 mph. When select drive will not shift into high without slipping an rapid rpm increase. Currently 135k service record's and general appearance were well maintained....

So here I am driving away for the fuel station and then the tranny tries to shift and I hear and feel a loud clunk followed by no power. I have had no previous issues with the tranny but I believe it has not had any previous work done. The truck is an 02 7.3L with 200500 miles. I am guessing the torque converter is the culprit it still had very little forward motion when I tried to move the truck didn't matter what gear I was in. I intend to have the tranny beefed up but don't intend to go crazy. I do tow an 11,000 lbs TT on a fairly regular basis and have a PHP 6 position switch which can be set for as much as 120 hp from stock but don't do any hot rodding. I am mostly just looking to beef it up and provide as much strength towing.

So I have installed a 331 stroker with an AOD trans in an early Bronco.
The question is... What is the correct procedure for getting the lock up converter to function? How does it need to be wired?

I have an 06 Ford Expedition 2WD with 97,000 miles. Whenever I am backing up with the wheels turned hard to the right (such as backing out of a parking space) there is a loud pop on the driver's side after about 1/2 to 1 full wheel revolution (I am guessing about that part but that seems about right - the point is it's not real far). When I drive forward with the wheel turned the same way there is a similar sound, though less distinct. I have not heard it with the wheels turned left, and the sound only happens when the wheels are turning and it is one distinct pop (no grinding or clicking or anything, just one pop) on the drivers side. I have read guesses that cover pretty much every component on the front end.

My 94 e4od does a few things. It doesn't seem to engage positively all the time. It doesn't grab well in manual 1st, but does in D. I had the FIPL reset at the dealership and he said he never saw a FIPL needing to be set so far one way. Also it has overheated a few times. Either the TC doesn't lock up correctly or its just not all the way in gear (if thats possible) I changed the fluid but it did it again recently.
Also the speedometer is jumping around like a nut case, the abs light is on...sometimes, when I have the headlights on and put my right turn signal on it feels like the TC locks up. Oh, yeah the lights are all jacked up in the back. The left turn signal light also has a small amount of voltage when I put the headlamps on (my test light lights up dimly) I thought it might be the multi function switch so I removed that and cleaned the connections. Nothing changed but I dont think that was it. I have troubleshoot this all day and I don't have too much of a clue to whats going on.

I have a f150 2002 with a 5.4 and 4r100 (yes im sure), and a week ago my torque converter started getting stock (locked) when i came to a stop making the engine stall (it took a couple of minutes before my engine got warmed up). I checked the codes and got 0740 and 0743 which relate to the tcc solenoid malfunctioning. To make sure the tc wasn't physically stuck y cut the purple wire that signals the solenoid to lock the converter, the truck ran fine and as expected the tcc never locked.
So I thought I narrowed it down to the solenoid pack, which I bought (300 bucks ouch) and changed it yesterday. Today again the same thing started happening and the truck is throwing me the same codes, so I am a bit frustrated. I don't wanna go ahead and buy a torque converter without knowing the real cause, what could it be? I didn't see any melted wires down there but could my long tubes be shorting that wire out randomly in an unseen place? or could my tc be bad?

I just replaced my starter and on my first ride after replacing it the X started to stumble a bit, and then would stall out at almost every stop light. It threw a CE light and I pulled the code P0720. I searched here and it seems most guys say this is a C.O.P. issue. If it is a bad C.O.P. would it stall like that?
I did have the battery disconnected but I made sure the terminals were clean and tight. Is this a coincidence or did I do something while changing the starter?
