Title says it all. Chirping sounds almost like belt noise but appears to be coming underneath the vehicle (and from further back than the drivers seat). Goes away as soon as I turn off tow haul (which provides engine braking). A quick visual inspection finds nothing amiss. Trucks runs and drives normally with or without tow haul.
View 14 RepliesI replaced my fan clutch... Not a bad job, did it a couple weeks ago. I don't drive the truck much, but took it out today for the second time in the two weeks since I replaced it. The fan stays engaged until the truck hit operating temperature it seems. Is that normal?
View 1 Replies2004 F-250 6.0 Turbo Diesel W/ Torque Shift Transmission. Im having a problem with my Check Gauge light coming on and Tow Haul light flashing on my 04 F-250. I got a Transmission Fluid Temperature Sensor from my local Ford Dealership. They also said i needed to replace the Transmission harness for this application because of an open circuit.
My questions are, Is Mercon SP the only ATF that can be used on the Torque shift transmission and do i really need to replace the harness or just the sensor? I have read up a little on this and so far everything say's drain the fluid, drop the trans pan, swap out the sensor, replace the trans pan (torque setting is 11flbs I believe, correct me if I am wrong, replace with Mercon SP ATF and your good to go.
My engine cooling fan came on when I first started the truck, was reading of 2k on torque app, ECT was appx 100* with the EOT a little cooler after about 5-10 minutes things went to normal around 600 rpm. It did not happen anymore during the drive, I was seeing about 192* ECT and 198-200 EOT. I let her set for 2 days and took her to town and the fan was at normal RPM's, Is there any problems or is that normal?
View 9 RepliesIs there a way to auto engage the Tow/Haul mode when you plug in a trailer that requires brakes? Be nice since I sometimes forget to push the button after we stopped for lunch...
View 14 RepliesSo driving the other day and tow haul starts flashing. I come to a stop sign and goto take off and it barley takes off. It will barley roll if my foot is off the pedal sometimes wont even roll. Also won't shift into 6th. Once it gets rolling though say till about 25 it's fine. Just doesn't wanna take off? I scanned the trans but got no codes. And here are some pressures and stuff but I don't know what I'm looking for with the trans. This was all done in park.
View 14 RepliesHow do you diagnose a bad fan clutch? When driving in tow/haul mode I get a noise like a jet engine. It starts going down grade or upgrade and does not stop after leveling out. I have switched off tow/haul and it is still there. Over on the Diesel Stop site I found a couple of guys who have had the same problem. Concern is everything I have read there are no codes thrown. Have not taken to my local Ford Dealer to see what they say.
Driving a 2011 F-250, August 2010 build date with 76,500 miles. Problem started about 6 weeks ago when pulling an 8000 lb travel trailer in the White Mountains of NH.
Have a Gage fault and tow haul flashing on the dash have no clue what is going on?
View 8 RepliesI have a 2012 ford f350 SRW 4x4 with the 6.7L. Problem I have just started to have. When going downhill in tow haul the truck at first will hold you back then all of a sudden it starts to up shift at 20 mph it reaches 6th gear pretty quick. I talked to the dealer and they suggested I was pushing the shift buttons, but I am not. They told me to drive it till next week and then they will see if there are any codes in it.
View 14 RepliesIn addition to significantly louder noise from the Turbo on start-up, we've started to hear a pretty concerning noise while descending a hill in Tow-Haul. Not sure that the T/H has anything to do with it other than getting the engine in a RPM range that causes the noise. We've taken it in and tech says "That's just normal noise"... What ever that is.

My co-worker has an 06 F250 SC 4x4 and is getting a P0713 code. 2006 Ford F250 6.0L Diesel ... Tow/haul light comes on flashing at random times. Truck is reading a P0713 code which is the TFT Sensor Failure/Replacement
Ford dealership is telling me that I also have to pull the valve body and install the new upgraded wiring harness (3-3.5 hours labor) but a thread on this forum stated I just needed to replace the sensor in the tranny pan and reconnect the wire harness. Do I need to upgrade the wiring harness?
I have an 05 Excursion and I drove and parked it, no problem. Came back out and the trouble began. I looked on this site (always do for the best guidance and info) and replaced the trans position sensor, put tunes back to stock. Since then, I have had intermittent issues with the truck only starting with the code reader plugged in, idle jump to 750 rpm, and the tow/haul light flash and won't shift into OD. It also seems at full stops it is not in the low gear. I am driving it to the "stealership" today to have the computer flashed. Additionally, the blinkers won't flash, they only illuminate. All this started at once. Where all the ground straps/wires are??
View 6 RepliesQuick observation: with the exhaust brake switch off, I notice it appears that the exhaust brake is still working automatically when you are in Tow/Haul mode and apply the brakes coming down a hill.
I notice the engine drone and turbo boost gauge rise...although neither the drone nor the boost are as noticeable as when the switch is turned on.
I know the 2011-2014 had "auto exhaust brake only" but it appears some of that functionality is still built in.
Another question: what is the consequence of turning the exhaust brake on and leaving it on for normal driving? Is mpg affected? Engine output? Engine wear?

I've got a strange squeal sound coming from under the hood only when truck is cold? It sounds like a bearing and after it gets heated up the sound stops. I talked with a guy thats a cummins guy and he said he had a similar issue and he had to replace the bearing in the turbo? Also when truck is warm it will still do it, like for instance, if I run in a store and truck idles for 5-10 mins it will do it only if I romp on it for a short while like 2-3 mins then again goes away. And if I'm idling or in neutral, hot/cold, it does not do it, it seems to be only under a load. Pull a 26 foot boat no problems.
What could be making the strange pumping sound coming from under my hood after I shut off the truck?? It sounds like a small compressor or pump running.
View 4 RepliesToday I drove to dinner in my 2012 6.7 with no problems then on the way home my brother said he noticed my truck was white smoking quite a bit and he said there was a very strong exhaust smell coming from my truck ( he was in his car behind me) I ran a diagnostic test and what came up was code P0401 (I believe that's right). Need to figure out what is going on with my truck before I take it to the mechanics and get charged up. The truck still has DPFs in it just has a DPF back exhaust and has a AFE cold air intake running on a stock tune. However I do have the DPF deletes and EGR delete sitting in my garage just haven't gotten them on the truck yet.
View 2 RepliesIt's on my 2015 f-250....dont know if this is a new thing ..... I know my 2011 f-350 didn't have it..... Really hardly notice its working ....it slightly slows me down when in tow/haul mode while braking......
View 14 RepliesMy friend has a 2006 F-450 and he said the Tow/Haul light blinks and the shifts are real slow. He has stopped towing now and it still drives.
I have read everything from toasted tranny to chaffed wire harness across tranny crossmember to the TFT sensor. My guess is the TFT sensor given his symptoms. If I am right the sensor is just to the rear of where the dipstick comes thru the tranny case. 1/4 turn and pull it out. Kinda like a bulb I guess.
Another question, is it necessary to replace the harness while in there as well? Is the Connection listed below the harness I am asking about? I found these parts on a thread from here:
Sensor (1): 3C3Z-7H141-AA;
Connection (1) 4C3Z-7G276-AA;
Gasket (1): 3C3Z-7C155-DA;
Fluid (10): XT-6-QSP
Okay so I just peaked 100k and (of course) my 6.0 has an issue. I was driving along when suddenly my Transmission Temp gauge dropped to nothing, the tow haul began flashing and my check engine light came on. My transmission hard shifted and wouldn't shift up from 3rd. I let the truck sit for a few days, no leaking was observed and no blown lines. I added 4qts of tranny fluid and went to take it for a spin. The truck did fine for about 20 minutes and the same issue occurred. I parked it and checked the dip stick and it was full. What could the issue be.
View 5 Replies06 6.0 fan clutch stuck in engaged position. So I changed the fan clutch it doesn't stay engaged anymore. comes on during startup and gives the appearance that the batteries are dying. Stays on for about 10 minutes when first driving then goes off. If I run ac it comes on at every light and it doesn't matter what engine coolant temp or oil temp and they are all within 6 degrees of each other. I'm thinking maybe the AC is a issue or bad sensor somewhere. No codes everything seems to be functioning. When I say comes on it's on high speed roaring.
View 14 RepliesI used my 4x4 high for the first time. I switched it on at about 40mph on an icy road and heard a quick grind as it engaged. After it was active I noticed that I the truck sounded different. Not bad necessarily but I could definitely hear that the front drive shaft was engaged as I drove along. Is this normal? In my last Ram, the truck didn't sound any different as it operated in 4x4.
