Ford Excursion :: Transmission Making A Whining Noise - Torque Converter Or Pump
Mar 20, 2012
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.

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.

I have a 2004 Explorer 4.0L with 190,000 miles. My wife was driving it and the vehicle stopped moving. Sounds like the torque converter whining and will not drive in any gear or 4wd.

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.

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 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.

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.

So I have a 2012 Elantra Limited. From what I understand the power steering is no hydraulics and is only electric assist. So I have a strange problem. I can remember in previous cars when a power steering pump was going bad it made a whining type noise that changed with engine speed. My Elantra is making the same type of noise. I'm trying to track this down. My car doesn't have any other symptoms aside from the noise. It's hard to really tell but it does appear to be coming from the belt side of the motor (passenger side).

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 have a 2002 SuperCrew 4x4 that makes a squealing sound that starts at 3000 rpm and slowly goes away as it approaches 4000 rpm. It does this when you are in park or in gear. I believe the torque converter is going bad, but just want to make sure before I tear it all down.

I removed my drift shaft to get balanced since I have felt a vibration at 55-60 mph. After removing the driveshaft I noticed there is some play in the output shaft when I grab a hold of the yoke on the transmission. The play is a slightly up and down. If my memory serves me right that should not be. Seal is not leaking but need diagram of this yoke off the output shaft. I know in past on other vehicles there is sometimes a crush washer. Also what is the torque specification for that output shaft nut?

My power steering pump was making a loud whining sound. No problem, changed the pump. Now after the truck is started I will have no power steering or brake assist, give the truck a little gas and you can hear the power steering pump "start". I have tried every way to get the air out, or is that not the problem. I even lifted the front of the truck off the ground with a forklift and with the truck off turned the wheel about six times stop to stop. Fluid level looks good and has since adding after the change.

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.
