Where is the plug on the transmission to disconnect the TCC solenoid? I am trying to diagnose a lockup issue and need to disable the clutch from engaging for a test run.
View 1 RepliesI recently purchased this truck so I don't have any history on it. It's the V10 motor, automatic, 4 wheel drive, with a crew cab. I took it to Advance Auto to have them read codes and it came back with torque converter solenoid fault and 2 other codes related to that part. I didn't get to see the actual code numbers.
I've talked to 2 transmission shops and they said they could throw a solenoid pack into it, but that it might not even fix it. The truck drives fine, shifts fine, the tranny oil looks and smells fine, so I'm tempted to not worry about it until something else happens.
The truck has 217,000 miles on it...
I have a 1997 Dodge Avenger ES that reads code P0743 Torque Converter Clutch Solenoid. I've replaced the transmission control module, and filter. I've called the Dodge dealership and asked if the new transmission control module needs to be programmed. The service department said "Possibly" I said "Well it's shifting better than before. If there wasn't any firmware on it what would it do?" He said "My guess it that the car wouldn't shift." I asked if the Torque Converter Clutch Solenoid visible once you remove the filter. He said "I'm not sure." Clearly, my car isn't going there. Then asked to be transfer to the Parts department to see if there was a part called Torque converter clutch solenoid. That answer was "No" there isn't a part listed called "Torque Converter Clutch Solenoid". What should I do or try?
View 9 RepliesHow can I fix the P0741 engine code? Vehicle has 100k mileage.
Some of the on and off symptoms: loss of power, doesn't go over 40mph on the bridge, rpm dramatically goes high at low speed, lower mpg.
I did a tune-up: [URL] .... 2Bplugs, engine, coolant, [URL] .... 2Bfluid, steering, ignition coils, short ram intake filter cleaned.
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 picked up a 2015 gs350 f sport in atomic silver / black. I'm excited to pull out of the parking lot and get on the road! Yeah, not so much. As I take a turn onto the road I notice it's very sluggish, like starting off in third gear sluggish. I eventually get up to speed and wander if the floor mat is stuck under the pedal or something, whatever. anything but the car is broken.
I eventually get up to speed. Everything is fine. I don't accelerate hard because the the car only has 12 miles on it. Otherwise it drives like it should. Off the freeway and at a stoplight with an incline. Start to go, same thing. I pull over, turn the ignition off and back on. Car is fine.
So later that night (43 miles on the ODO) CEL and Trac off lights up. Car will not get up over third gear. Make it another 2 miles home and park it. I'm pretty distraught.
Took it to the dealership, don't know what they are but 2 fault codes came up. One for a shift solenoid and another having to do with the torque converter. Under 100 miles on the ODO!
So I'm with a red ES loaner car. Never seen it on a brand new car.
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.
I am having a minor problem with my 05 F150 Lariat. Under light acceleration going up a slight grade the truck sometimes shudders (vibrates?). If I let off the gas or accelerate slightly it stops. At first I thought it was a feedback loop with the electronic throttle so I had the dealer reflash the computer but that didn't fix it. I've noticed that it happens right about the time the torque converter locks (looking at the tach) and I'm sure it has something to do with torque converter locking up and then disengaging continuously. Funny thing, it seems to happen frequently on the same hill at the same speed. What was done to fix it?
View 14 RepliesGirlfriend 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 RepliesGonna change my oil in a hour or so and I was wondering what the torque spec is for the oil drain plug.
View 3 RepliesIn the "Old days" I could pull the one-and-only coil wire and trigger the starter motor to rotate the converter so the plug was at the bottom. How do ya do this with COP engines so the engine does not start?
View 4 RepliesI 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.
My girlfriend's 2001 cavalier has about 160k on it and about a week ago it started shifting harshly accelerating to highway speeds and the CEL came on along with the traction control/abs warning light. I pulled the OBD2 code and it was P0742, Torque Converter Clutch Circuit Stuck On. We took it to the transmission shop down the street the next day and they wanted $600 to diagnose. We called 'shenanigans' and decided she should take it to her regular shop. On the drive over the transmission shifted normally. Both shops noticed that the transmission cooler lines were rusty and seeping, but neither thought it was the cause of the problem. The shifting issue hasn't recurred even after a couple hundred miles during the week. She hasn't had the transmission fluid changed and doesn't know if it had been when she bought it about 80k miles ago. It seems to me that pre-emptively draining the fluid, changing the filter and refilling, especially to check for debris in the fluid, would make sense, especially if it was debris jamming the circuit that caused the error code in the first place.
View 8 RepliesMy 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.
This car has been giving me quite a bit of trouble lately. 04 Ford Taurus SES, about 97,000 miles on it. Just last weekend, it broke down on the highway. Found out the torque converter failed and needed to be replaced. I was suspecting that something was wrong with the transmission for a while now, because it would stutter sometimes when accelerating, and sometimes start shaking in the front when I turned it on. (It still stutters after having the torque converter replaced.)
Well now, a day after shelling out quite a bit of money to the dealer for this torque converter, the check engine light is on. I went to Autozone to check the codes, and they found P0300, P0305 (cylinder misfire) and P0316 ("crank sensor condition"). Is it possible the transmission is failing?? I found a bunch of complaints online about the transmission failing on the 04 Taurus. I'm trying to avoid more expensive repairs, but I don't want the car to break down on me again....
Also, a couple months ago, the check engine light went on a few times, but always went off within a day or two. Never did get it checked out because it didn't stay on long enough.
Have a 2004 hyundai accent and I think I am having problems with the torque converter locking up in a timely fashion. It typically takes 15 to 20 minutes when I am driving on the highway. Is this normal for it to take that long? My gas mileage is terrible (22 mpg last fillup) and I am thinking its related to this.
View 7 RepliesI 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.
View 1 RepliesSo 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 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 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?
