Ford Transmission :: 4r100 - Torque Converter Started Getting Locked
Apr 25, 2012
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?

2000 Explorer 4.0 dohc avd. 150k miles. The torque converter lock-up function has started to drop out. It can happen after some miles and will light a warning light in the dash that the manual states as "contact tech" or something like that. Everything gets back to normal with just a "blip" to "off-position for the ignition switch and might stay normal for all between 5 minutes to several hours. Seems to me it is an electrical issue. Dirt, sensors?
Runs and shifts fine other than this. Only thing I have noticed is that the temp gauge reads pretty low but I think this started earlier and I understand that the temp gauge has its own sensor. Where to start looking?

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.

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 was driving my 7.3 down the road and it started acting like the trans was slipping, it revved up and tried kicking down a couple times and when I slowed down and went to speed back up it just had no power coming through the trans to the wheels it just revved. I put it in neutral and it idled up for about 5 seconds. I put it in park n shut it down. I fired it back up after looking everything over and it moved about half mile down the road and no power to the wheels again. The trans is full of fluid, is there a sensor that could of went bad or just the torque converter or the entire thing shot? Only owned my truck 6 months has a trans and motor swap already from previous owner. 180k on current motor n Trans. 382k on my truck. t6 4" turbo back banks exhaust only mods I know of.

My 1996 F150 has developed a strange vibration and nothing i have done seems to work. once it has shifted into drive it will shutter or vibrate under a light load. if i let off throttle or give it more throttle it stops. Seems to be most noticeable from 30-55 mph. I am thinking it is torque converter locking and unlocking but not sure. if it is torque converter does the converter lock and unlock electrically? if so where is the sensor on the bellhousing? I have looked around and cannot find anything as i was going to unplug it to see that was indeed the problem. its a 4rw70 tranny.

I recently bought a 2001 x w 145,000 miles. The transmission was making a whining noise when i bought it but it still shifted smooth and ran great. The truck has been serviced by the local Ford dealer its entire life with dozens of routine maintenance performed. With 145,000 miles should I wait for the converter to go out and just install a new transmission. It only gets drove on the weekends to go to the lake.

Before taking to Ford or random trans shop just yet, looking for diagnosis recommendations (or an item or two to replace DIY). Torque converter bolts are broken or TC itself? Solenoid (but would expect a code)?
Issue: Doing 45MPH at the tail end of the 6hr drive, then engine simply revved and coasted to stop. No lurch, pop, noise felt like a manual transmission popped out of gear and into neutral. When the shift to R/D/L/4x4 hi/lo, can feel transmission engage. Engine revs and 'slips' are the best way to describe (no abnormal noise otherwise)I can feel it applying a very slight load (doesn't move, but can feel it try). No warnings/issues leading up to this in the 6yrs and 100k miles I have owned (has 174k miles now). No leaks/visible issues underneath.
Fluid is not burnt, the level is ok. Replaced (no flush) Mercon SP fluid at 125k when bulletproofing. No codes, including hard codes. Trans temp was 165 before/after, which is normal. All engine temps/values on Scanguage normal. SCT tune since bulletproof (though don't abuses it), set back to stock. Also disconnected pos/neg and touched both sets of cables together for several mins.

I have a 2007 Sonata, performs flawlessly, my wife's 2011 Elantra, not so much. We've had issues with her car from the get-go. The Elantra has 32k miles on it. About 15k miles ago the dealership reprogrammed the transmission. Problem seemed to be fixed, to a degree. Hiccup here and there.
Last night when my wife came home from work she said it was shifting hard. I just shrugged it off. We came in to town, about 5 miles down a busy highway. 55mph, no problems.
Car sat for a couple hours. We got in the car to come home, buttery smooth first few shifts to 35 mph. Car had probably been running about 5 minutes. Pulled out onto highway, shifts 1-2 fine, 2-3 holds about 2500 rpms, won't shift, won't shift, BAM! repeat 3-4, and I believe 4-5. I was so shaken up I didn't count. I pulled off and took the back road and it continued to do it for about 3 miles. It almost feels like the torque converter is locking up. Someone mentioned a transmission temperature sensor, but that is only in Sonata's, no one has seen it in an Elantra.
By the time we got home, the car was shifting normal. This morning I get in it because now my wife won't drive it, and it works fine. Works fine all day.
Go into dealership, they say everything is fine, they called Hyundai, they say nothing wrong, come back when you have a problem.

I have a 2001 Montana with 140,000 miles on it. I bought it used five years ago. The transmission is going out. The shop did a scan and found the torque converter clutch is sticking on. What this is? Should I make the repairs or ditch the van?
Good points: four new tires in December 2013; body is great; and minor maintenance repairs.
Bad points: the air conditioning is broken and the heat is forever terrible.
The van is currently at my regular shop and they do not do transmissions so I do not have an estimate or more information about the problem.

The problem is that it appears the torque converter is locking up so early even right after getting into second gear at speeds between 20km/h and 40km/h. This causes shuddering/rattling coming from under the hood. If I am not mistaken a torque converter should lock up at speeds 80km/h+. I've never seen this behavior on any car before. I'm not sure what kind of damage is being done either by all this shuddering and rattling going on with the transmission. I feel that this should be something that needs to be addressed via some software update. Is there any software update in regards to this issue?

I highjacked another thread yesterday but didn't get many responses so I thought I would start a new one... I've done some searching here but no one had any real answers or had a different reason for the vibration...
We have a stock '05 F150 with 24k mi that is having Vibrations not related to bad tires or a bad trailer. It rattles any cups or change that is in the center console area and the dashboard. It seems to come up through the floor.
Symptoms timeline:
The rear pops when you turn tight in a parking lot. I've been told this is normal because of the ratcheting LSD? Is this true?
The tranny fluid was low and we could not find where it was going. Put several qts in it and finally took it to the dealer where they replaced the bad seal between the transmission and transfer case. So we know they took the driveshaft out and the transfer case. Not sure if they dropped the transmission out.
We have a vibration from about 40mph-55mph under medium-full throttle. A lot worse when towing. Put it in neutral and it goes away. Rev the motor and you don't feel it. Only happens under load. Happens in 3 and 4th gear. Goes away once the torque converter locks up.
Am I going down the right path in saying it's a bad torque converter?

I drive a 1997 Ford Explorer XLT 4X4 with 180,000 miles. A couple months ago my O/D light started flashing. When ever the code flashed i would pull over and I would take the negative cable off to get the codes to clear. While driving it, it would shift normally in till i go to about 40 mph. Then the light would come on and the torque converter would refuse to lock up. I would be in 4th gear at high rpms and when i came to a stop there would be a hard 2-1 shift. I tried solving this by changing the fluid and filter twice. I also replaced the valve body gasket and tcc solenoid. This solved nothing and it continued to do the same thing as before.
I then took it to 2 shops. One told me they go the code for the torque converter and that i would need to replace the whole tranny. The next place told me some internal pump was failing and that a rebuild was recommended. After this I continued to drive it knowing there was no point in trying to save the original tranny. My dads best friend owns a shop about an hour away and said he would replace it with a used one for free. All i had to do is pay for parts. Then one day while driving the transmission blew up and i lost all my gears. Then it was taken to my dads best friends shop. While it was there he replaced it with a used one along with a couple other parts like the starter.
After the used tranny was put in the same problems still kept happening. They tried clearing the code having no luck. I eventually picked it up my self and took it back home to deal with. I can now get the torque converter to lock up but it doesn't want to till I am going over 50mph and at high rpms. The light still comes on when i get to about 40 mphs. I tried clearing the PCM and that fixed nothing. Then i tried replacing the thermostat( It was bad anyways) thinking that the thermostat was not sending the right info to the pcm to make the torque converter lock. Now im completely stuck. What could be causing the problem. I know there are a ton of external sensors that control the torque converter lock up.

My wife's 2004 Ford Taurus has been acting up. It shudders sometimes at stoplights and also while driving sometimes. The auto parts store plugged in the computer and said it was the torque converter not working properly. We took it to "The Answer" in Evansville, Indiana for their advertised free diagnosis. They checked it out and told us basically the same thing. The torque converter was acting up. (Slipping? Catching? I don't remember the exact details...)
They said the remedy would be a big expensive job (install rebuilt transmission? Replace torque converter?). Is there anything we can do to prolong the inevitable such as fluid, filter change...flush...additive? We are resigned to the fact that we will need to buy another vehicle but wonder if we should buy one now since the Taurus may only last another few weeks or can we put off buying another car because the Taurus may last another six to twelve or more months.

Girlfriend got a 98 ex. got a CEL for a torque converter clutch circuit. Changed out the TCC and the light is still on. I don't know what to do next.

Need to diagnose:
- Truck idles a little rough sounds a little like " puff , puff ", when put in reverse - still sounds the same ( looping hesitation )
- When accelerating feels pretty good until about 40-45 then it starts to shake , shudder and loose power. Shakes and shudder pretty violently.
Did a full ATF fluid service - no improvement
Aside from that it does not seem to have any other shifting issues at all. Problem is intermittent. Throughout the day it may run fine, and then at another point in the day it runs like poop when hitting 45+.
Could it be a bad Ignition Coil Pack ? Car has ZERO codes appearing - would either TC or COP set one off ?
Here is a pic of the one COP that I found does have a crack on the top ( passenger side ) - not sure if that could cause the truck to act the way it does.

I have a 97 F-150 Supercab XLT, 4X4, 4.6L W, 4r70W with electronic Overdrive, manual shift transfer case. I need to remove and replace the Torque Converter. My question is: Would it be easier to drop the transmission and transfer case or pull the engine loose and move it forward to get at the torque converter?
It is shifting in and out of overdrive to third, and then back into OD, and back into third erratically and for no apparent reason. It is also slipping intermittently in first from a dead stop and locking all at once, shifts hard then. When I first drive it the OD light does not flash and the OD off switch works, once it warms up good it starts shifting erratically and the OD off switch starts flashing, then the off switch does not work.
I did not get any codes returned on autozones little scanner and am taking it to the ford dealer for a full scan today to see if there might be any other damage or cause for this problem. The problems started when I blew a hose to the trans cooler in the radiator and lost fluid. I didn't notice the blown hose until it started slipping and pulled over, replaced the hose and fluid. Had problems ever since. I have cleaned the MAF sensor and replaced the ABS sensor in the differential so far.

Been doing a lot of reading about shudder/vibration on the 2011+ F150's and it seems to all center around the two piece driveshaft found on the longer wheelbases and more during take-off than other times. I have an '11 5.0L 4x4/auto with the 145 wheelbase and the 1-piece aluminum driveshaft and am experiencing a shudder in 3rd gear primarily, most noticeable during light acceleration with medium load (like gently accelerating up a slight incline).
When this is occurring I can see the tach needle fluctuating just slightly (maybe 50-150rpms, just barely bouncing) but I have no check engine light and the only time I have take-off shudder is under hard acceleration which feels like axle hop (which isn't too rare on soft leaf springs with 360hp engines!).
Anyways, this 3rd gear shudder is very soft and nobody has noticed it that has rode in the truck with me, but it sure feels like the old AODE/4R70W trans would when the fluid was getting old and the TC started to shudder during "soft" lock. 5.0L? Certainly could be a miss, though power is good, mileage is great and no CEL is lit...

With my first tow under my belt from this weekend in my new-to-me truck, I quickly learned that my TC shutters in 5th if I hold fuel down enough to bog the truck before it wants to down shift. The shutters are pretty violent as compared to others I've experienced in Explorers and F150s. When do you know it is time to change it out? Or, is there something else I can or should do before changing it?

I bought an 07 F150 5.4 4x4 with 135k on it about 6 months ago. Shortly after buying the truck I began experiencing a shudder when lightly accelerating up a hill. Also when accelerating hard it would misfire. Thinking that it was plugs or COPs I changed the plugs and coils. That fixed the missfire issue but it still shuddered when accelerating up a hill.
I decided to take it back to the used car dealer where I bought it so they could fix it. On the way there the fly wheel broke. The dealer replaced it and thought that it was the cause of the problem but on the way home I still experienced the shudder. I took it back and they "scoped" it and found that the torque converter was bad. They replaced the TC and now there is no more shudder BUT now I have a new problem.
Now if I am driving at highway speed and let off the gas it feels like it immediately down shifts for a few seconds then shifts back up and coasts along until I give it gas again. There is enough resistance that it feels like a jake brake or that the breaks are being applied. Also if driving along at 30 - 40 mph and just holding the gas in the same spot maintaining 30-40 it feels like it down shifts and up shifts over and over until I either give it more gas or let off all together. Also a few times pulling away from a stop I will get a thump.
I have an appointment with a transmission shop in a few days but today on the way home I put it in second gear while going up a hill so it would not shift and it seemed like it was coughing and sputtering. So now I am wondering if that is what is happening and either feeling like or causing the down shift up shift issue.
If it is a missfire issue why would the new torque converter cause this? It has all new motor craft plugs and all new after market coils.
There are no check engine or other warning lights lit on the dash. I have a cheap ODB scanner and it shows two codes. B1676 which apparently is a Battery Pack Voltage Out Of Range or ABS voltage issue. The voltage is showing at 14.2 volts and there is no noticeable battery issues. The second code is a P1000 Drive cycle test not complete. (this code has been showing for some time the 1676 code is new since the torque converter swap)
One side note: after the TC change every time I start the truck the radio/cd changer cycles though all the CDs. like it it is checking for a disk so it clicks and pops around from a moment. The only time I heard this happen before was after having the battery disconnected. The clock is not reset though like I would expect if it was losing all power.
