Ford 6.7L Power Stroke Diesel :: When Engage Low Range In The Diesel / Transmission Starts In 2nd Gear
Well, last night I took my F-350 up a wheeling trail. I'd been up quite a few times in my old Rover, so I knew I could go a ways in without damage. Just uphill, muddy, and ruts / rock steps.
One thing I notice is that when you engage low range in the diesel, the transmission starts in 2nd gear. My previous gas Super Duties always started in 1st. I'm assuming this is to protect the transfer case from torque overload. Also, the throttle response seems to change when low is engaged (the pedal becomes less responsive, which is nice).
I've had the gas Super Duties off road before, and all of mine have had the locking rear diff. The diesel lugged along perfectly. My biggest fear was crunching the DPF / SCR / DOC canister on a rock step. In that respect, I'd rather wheel a gas. The manual shift function makes a lot of sense in low range - you can force a start in 1st, 2nd, or 3rd. And prevent meaningless up / down shifts since the grade can change quickly.
These trucks' biggest hindrance is their size. However, if you have the trail room, they are actually excellent off road. Many people look at a Super Duty and see a vehicle good only for pulling or hauling. Not so, these trucks are as good as a Jeep off road, again with trail room being the only concern. The locking rear diff was never really needed, but I engaged and disengaged a few times to keep the mechanism free. I really love this feature.
One thing that happens frequently for me in north-east wheeling is water crossings. Could be a simple brook but mostly it is mud holes encountered on tight trails. In some cases these are only a foot or so deep; in other cases they are 4 feet deep. Ford states to "try" to keep the water below the level of the hubs, which amounts to about 15". Aside from possible front axle contamination, my biggest concern would be the electronics on the diesel which are mounted to the frame or floor pan (transmission module, NOx module, etc.) The gas Super Duties don't have these concerns. In the old days, as long as a diesel had air, the engine would run under water. This engine requires electronic control of many things, including the injectors...so it won't. There are also some axle / transmission breathers which run about floor pan high to be concerned about, but these can be easily extended.
Maybe it's due to the twisty frame which GM loves to insult Ford about, but these trucks have excellent wheel articulation. I'd be surprised if a coil sprung power wagon flexed more, at least in the rear. I'm impressed.
Finally, the traction control. I experimented a bit on a slippery rock step. This was the only step which required the rear locker - sort of. The front wheels climbed the step, but the back flexed to the point of one rear wheel basically almost off the ground and severely unloaded. With 4x4 Low engaged, and traction control "off" as much as Ford will allow, the truck could not pull itself up. Turning traction control on allowed the truck to very nearly pull itself up. A little more throttle / finesse probably would have gotten the truck over, but lots of ETC operation glazes the brakes and spews brake dust everywhere. Being able to start in a higher gear manually really adjusts the torque control. Locking the rear end and the loaded wheel bit right in and she went up and over.
When doing some off-road driving, the "off-road" screen for those of you with the LCD message center is kind of fun and informative to watch. It's nice to see how far your wheels are turned left or right when spinning in ruts or what crazy angle your truck is on. Howie Long could probably document the exact up / down / left / right slope angle a Super Duty needs to be on in order for the tailgate not to open. I never had an reason to open the tailgate while in these crazy angles, of course.
Overall, very impressed. It's not as good as my old Range Rover, but I would say more talented off road than ALL other Ford vehicles except the Raptor.
Ford 6.0L Power Stroke Diesel :: Theft Light Blinking - Overhead Light On?

Idiot light was on for battery charging issues. Sanded all ground connections. Soldered battery cable connections. Scan gauge showed sporadic inadequate charging. Installed new alternator. Scan gauge showed sporadic inadequate charging. Installed new interstate batteries. Brought old alternator to be rebuilt, rebuilder said it was strong as could be, needed no work, high output alternator. Reinstalled old high output alternator. Scan gauge now shows charge output of 13.9 V to 14.1 V
Idiot light still on, flickers like a loose connection, sometimes lights constantly.Occasionally speedometer fluctuates wildly, when fluctuating like this at idle, the truck will stall, so far it restarts...so far. When it has stalled the speedometer still fluctuates wildly for a few seconds truck will restart and seem fines but this will play out again next day or so. Occasionally ABS light comes on, occasionally water in fuel light comes on and they go away after abit, some times after a restart, not always though
Thought it might be cam positon sensor however not certain with the instrument lights also acting as they do. Have had one cam position sensor open circuit code once, about to trip out west to Monatana & Colorado and back home to Ma in a couple of weeks, hoping not to be stranded somewhere in between those places!
Ford 6.0L Power Stroke Diesel :: 2005 - Transmission Temp Gauge Dropped / Tow Haul Began Flashing
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.

My 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
Ford 6.0L Power Stroke Diesel :: Truck Died And Coasted To A Stop - Theft Light Blinking / No Start
I was driving home tonight and stopped at stop sign. I took off and truck died and coasted to a stop. I tried to start but all it does is theft light blinks really fast and will not turn motor over. I tried to reset pat by following procedure I found on internet. Still no start. I then unhooked battery cables and left off for 15 minutes then hooked up but still no start and blinking theft light. I also tried spare key and still no start. What else can I do. I had it towed to place that just bulletproof my truck. Truck has been running great. I did not want to leave it on the side off road in the middle of country all night.

2004 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.
Ford 6.0L Power Stroke Diesel :: 2004 F350 - Check Gauge Light Came On And Tow Haul Light Started Flashing
Friday I pulled my steel gn 3 horse trailer about an hour each way. with the horses it weighs right at 7000 pounds. no issues. Saturday morning I drove to town, no issues. Saturday evening, I got in it to run down the road and about 2 miles from the house, the check engine light came on and the tow haul light started flashing and the temp gauge is dead. drives and shifts normal, tow haul button still functions. Truck is stock except for an EGR delete. No tuner, FICM was rebuilt. I had it on a battery minder before I left and was thinking about pulling the batteries and letting it sit for a while to see if it clears. Scan Gauge II shows no codes.
Sunday: So I let it sit all night, batteries connected and it was completely normal this morning. will see what happens when I drive it to work tomorrow
Later Sunday evening: So I just took it out for a test drive, went a couple miles down the road, shifting normal for a cold start. Temp gauge is working, just as I am almost back home. 5 miles at the most, temp is coming up to normal, gauge goes dead and check gauge light comes on and tow haul starts flashing. I think it might be the sensor.
This morning: I got about 6 or 7 miles from home, trans just got up to temp, pulling up a hill, it shifted out of overdrive, tft gauge went dead, check gauge light came on and the tow haul light started flashing. still shifts like it always has and the tow haul button still functions.
I am thinking it is just the temp sensor. Truck has 159k on it.

View 4 RepliesFord 6.7L Power Stroke Diesel :: Check Engine Light And Funky Boost Gauge
Noticed the other day when I went to leave a job site my Check Engine Light came on but the truck started fine and seemed to run normal. while cruising down the highway I noticed that my factory boost gauge was showing 35psi and fluctuating between that and around 10. looking at my H&S it was showing normal boost readings for the current driving condition, when I came to a stop the H&S would show 0psi but the factory one would fluctuate between 0 and 35-40psi..
I can tell the turbo is not spooling at all during this time. if I take off from a stop with the gauge showing 35 the engine sounds louder than normal at first take off compared to when the gauge is reading normal. I haven't gotten a change to get it in my shop yet to look it over but does the dash gauge read from a different sensor that what my H&S is reading? Truck is an '11 F250, deleted both EGR and DPF with H&S tuner. I checked codes and all I have is P06A7. Where to start?
Ford 6.0L Power Stroke Diesel :: 2004 - Check Gauge Light On While Going Downhill Towing?
My 04 F 350 started with a check gauge light while going down hill towing an 18 ft car hauler full of mulch. Did it for 5 seconds, then when we got to our land and I was getting ready to back up it did it again. and this time my oil pressure gauge was at zero. I shut her down. checked the oil. its full. Drive home everything is good. Today I'm getting fuel pressure gauge going nuts. 80 to 100 PSI. at idle no oil pressure and the check gauge light. but the engine is still running. Oil was changed 4K ago. fuel filters same. Where to start looking?

I have a 2003 Excursion 6.0. I didn't post this in the 6.0 section because it may not be just a 6.0 issue. (See what I get) On cold starts, anything under 150 degree water temp reading on the SGII. I get a CHECK GAGE light on accompanied by the check engine light. No codes read on the SGII pending or stored. Just some of the time I get a water in fuel light too. This tends to go out fairly soon after driving. (Even after I just drain the fuel pump it still happens.) other issues that accompany the lights are as follows.
The trans temp does not give a reading to the dash. The oil temp does not give a reading the dash. Both show proper temp on the SGII. When in reverse the back up alarm beeps as if something is behind me. And the auto door locks will not activate after 10 mph. The tach also will not show a reading in the dash. SGII shows the numbers. Now the kicker, this ALL gets resolved the instant the water temp hits 150 degrees. The only lingering issue is the that the tach will surge or drop every now and then. The tow/haul light does not come on when this is going on. I've checked the battery terminals all are clean. Both batteries are brand new.
Ford 6.0L Power Stroke Diesel :: Check Gauges Light On And Trans Temp Gauge Pegged On Hot
Driving my 2003 today seen the "check gages" light on and the trans temp gage pegged on hot. CRAP, tranny time! look at the edge evo and it reads trans temp as -60F ???. Plugged in the torque pro and it reads 8,240F. At that point I figure its PROBABLY not that hot. Let it sit for a while and back to normal. Watch trans temp on torque pro as I drive it and everything is fine till it gets to about 150, then it jumps to 60F, then 30F, the 8240F. The cooler lines and trans pan are both feel normal. Picked up a new temp sender on my way home.

Any input on replacing the entire transmission valve body or just individual shift solenoids? My truck has begun experiencing a harsh shift from 1st to 2nd under light acceleration accompanied by occasional shift flare from 2nd to 3rd and 5th to 6th. I have located parts to do either job. It looks straight forward from just disconnecting the harness. I also understand there are different bands associated with the solenoids. Is there a requirement to have new transmission programming to accompany swapping these components?
