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.
View 1 RepliesI 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.
I have a '99 F150 w/ the 5.4 and 4R70W, with 226K miles. I am experiencing what I believe is a TC shudder after the tranny shifts into OD between approximately 40-50mph. This sounds like a pretty common problem with this particular tranny, but some of what I've read describes the shudder as feeling akin to driving over rumblestrips, but what I'm experiencing is a very sharp, bucking. Is this how the TC shudder feels, or am I actually dealing with a misfire. Btw, I did completely change the tranny fluid with Mercon V, and added a friction modifier, but no change. I also read that the TC unlocks when the brake lights come on, so I tried lightly hitting the brakes when the bucking was occuring, but it continued.
View 14 RepliesOver the last few days my f150 has developed a really annoying squeal that's intermittent. I can never really predict when Ill hear it. Usually I first hear it when I am accelerating to a speed greater than 30 or 40 mph. And it will continue if i keep my foot on the gas or if i slowly hit the brakes. Usually the only way it will stop is if I slow down to under roughly 30 or if i hit the brakes. pretty hard.
But sometimes Ill hear it at various speeds just for a second or two, usually when I am turning or when I am decelerating by taking my foot off the gas and not braking. again its hard to predict. It sounds really similar to a car with squeaky brakes. and just like squeaky brakes, you can hear the noise slow down as the f150 slows down. but again it doesnt only happen when i hit the brakes. I dont know what it is.
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.
View 14 RepliesSo my transmission drove perfectly fine I just wanted to put an upgraded torque converter in especially after driving a customers' truck with a low stall converter. I know their not like for racing or anything but it's a work Truck with some mods to the motor nothing crazy. So I went ahead and bought a low stall triple disk converter and I drove around the block fine and went to go on the freeway and got into fourth but lost it as I hit 75 (was not flooring by any means and had it in the stock tune) now it will not go past second gear. Once it did this the o/d off light started to flash and I decided to do a stall test.went to 1800 in a Second. Suppose to stall around 1200-1300.

1999 7.3/4r100 4wd with the rattling torque converter.
I bought this truck 10-11 years ago to use as a tow rig for my landscaping company. It has been a great problem free truck, I have done brakes a few times, a water pump, ball joints but no issues with motor/drivetrain.
I don't know the history of the trans before I purchased. Ford didn't have history of it being replaced and even now it still has all the labeling on the case. I would have thought it would have been washed off in a rebuild. Again I don't know. When I bought the truck it shifted nice and crisp, having owned trucks before it made me think it had been rebuilt but this was my first and only 4r100. Other trucks are ZF6 manuals.
Anyway 10 years and 100,000 miles later it still shifts very crisp and fluid, has been changed a couple times, is nice and cherry red. I added a 6.0 cooler, temp gauge and filter. Never see the temp rise and haven't seen much in the filter.
About 25,000 miles ago the TC started to rattle, a known 99 problem. I figured surely the trans would go and I would do a rebuilt from Ford. It keeps going though so being a work truck I have kept running it.
A couple weeks ago the starter just spun and wouldn't engage. I pulled the inspection cover and noticed some missing teeth on flex plate. Got it to start my turning crank bolt a bit to good teeth and the starter caught. Now we are carrying a breaker bar and socket. It has happened a few more times so I need to replace flex plate.
Question is, since I need to pull trans to replace flexplate, should I replace TC (I would like to get rid of the noise)? Some people have said I will be replacing trans in a couple months if I mess with it. They say just spend $3000 on a rebuilt now with a converter. Not trying to be cheap but hate to just dump this trans that is still working great and has served me well.
I have replaced many transmission and done clutches in many trucks so I am familiar with the steps of removal and installation, just stuck on what I should do.
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.
View 7 RepliesSwitch out a 5.4 in a F-250 4X4 4 my neighbor now I have a noise like fan blades hitting coming from the torque converter it goes and comes and hits good in reverse...
View 9 RepliesI have a 1997 f150 with the 4.6l triton that just started to make a squealing noise. I have replaced a couple of pulleys that were bad but that did not get rid of the problem. It only makes the noise when I give it some gas and it is coming from around the fan clutch area.
View 5 RepliesI've had this truck almost 2 yrs now. It is not a 4 x 4. The trouble I am having is on the driver side. What happened first was while I was driving it i heard a loud squealing noise then a loud pop. After that the truck seemed fine I checked under it and everything looked ok. After that I drove it to a couple stores did fine but i heard the loud pop again. Once I left the store I was driving on the highway and it jerked to the left and i heard a grinding/rattling noise. I put my flashers on slowed down and every once in a while it would still pull to the right but the grinding noise remained constant. I parked it waited for a tow and i turned the truck around and drove it up the ramp there was another pop sound but I didn't hear the grinding. It seems to happen on and off. And it doesn't matter if I am turning or going straight.
View 2 RepliesI have a 2000 b5 wagon with a 2.8 5spd with 200k on it .... Its slammed on coils and i get this squealing in reverse i dont know what it is i just rebuilt the front end ie control arms... also have a nasty vibration from 1000rpms to 3000 rpms could that be engine mounts/snub mount?
View 7 RepliesI have just finished changing head gasket. I started up the engine works fine. But I hear a little clik sound form the converter. I put it in gear, but it can't move either forward or backward. It ran 2-3 liters of oil out of the converter when I took the engine out. I have filled new oil in the gearbox but not in the converter, dosnt it came form the gearbox into the converter?Is there air in the converter or what's wrong?
it is a F150 4x4 4.6 1997 automatic.
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.
View 2 RepliesI 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.
Had it before, code p1401. Changed out dpfe and it worked for 6 months. Now spark knock again. Now though I have no codes though. No vacuum leaks that I can find. New egr from before I had the problem. I applied vacuum to the green hose and it stumbled so the ports should be ok. Snytime I go above 3000 rpm i get the pinging. I replaced the dpfe again and no difference.
View 3 RepliesI have a ford f150 supercab XLT with the 4.6L triton. It starts and idles absolutely fine but when i push the gas to fast(when in park) it bogs down. I just changed the fuel filter aslo...No change.
If I floor it it Bogs then goes up to about 3000rpm (about halfway) and has trouble moving over that RPM or halfway. like theres a restriction of some sort.
If I gradually push the gas, it will go up in rpms and i can get it to about 2000 rpms then I can tack the rpm gauge out if I wanted. but never do.
Also when driving, it seems as if its lacking power..and just to add it does all this stuff while in gear also..
When running It smells of an exhaust leak. but I cant find one. And I cant smell it in the cab.
So there it is. If I think of anything else, or do anything. I will keep posting.
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.
View 1 RepliesMy 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.
