Ford Super Duty (1999-2016) :: 5r110 With Code P0766 / Shifting Erratic And Trans Control System Fault
Feb 19, 2014
The truck belongs to a very good customer of mine and is a 05 f350sd 6.0 td with 5r110 torqshift tranny. The vehicle presents with these symptoms and codes....
-there is a delay from p to r and its intermittent, sometimes it will be in a weak reverse where it wont creep unless you give it some gas, sometimes it will hit reverse hard after this. sometimes it bangs reverse
-there is a delay into drive intermittently with the same symptoms as reverse where sometimes it bangs and sometimes it will take a little throttle to get it moving
-once the trans is hot (operating temperature) it has trouble downshifting. my solus tells me sometimes it tries to start off in 3 or 5 then sometimes it will bang back down into first and almost chirp tire with little throttle input
-tow haul light will flash after several miles and then it only has 1-2-3-4 no 5-6. then the starting off symptoms get worse
-throws codes for
p0766 shift sol d performance/stuck
p2701 friction element b apply time range/performance
p2703 friction element d apply time range/performance
p0700 trans control system fault.
So far the ideas i have are as follows
replace solenoid D
direct clutch replacement and seals for corresponding drum
torque converter replacement and pump replacement
harness rub through between pcm and transmission
The truck has had similar issues a year ago. Upon testing line pressure i found it was out of spec and replaced the epc. (electronic pressure control solenoid) and this cleared most of it up . I have had the pan down many times and the fluid has not been burnt and there is little debris in the pan. nothing i would consider beyond normal wear. Tomorrow I will be dropping the pan again to inspect the magnet and fluid as well as the condition of the harness. i will post my findings at that time. I am hoping between now and then some of you will be able to point out a few possibilities to get me on the right track.

Iv got a 2003 6.0 stroke with 212k miles on it. Runs like a top. Done a slew of work from injectors to hpop, 2 alternators, intake, exhaust. NO tuner! Stock. Anyway recently I started the old girl up, warmed up a bit and shifted into reverse and truck did nothing. Went to drive and same thing. Held brake and revved it up and it dropped in gear. Shifts fine after that. No issues other than the occasional NO shift from park problem. Iv dropped pan and replaced all filters recently.

My truck started acting up the other day with a flashing Tow/Haul light and CEL. The codes for the transmission were P0752 and P2700. I swapped out the SSPC-A solenoid unhooked the batteries for an hour and there was no change.
I hooked up a 100lb oil pressure gauge to the 1/8"npt outlet on the side of the tranny. At startup it immediately pegged the gauge....forever, lol. The gauge is toast now. Upon starting is has oil pressure visible in the see through line of the oil pressure gauge. But....if you tap the throttle in park for a second, the line looses pressure (by seeing the oil go back toward the transmission). Without pressure, when you put it in drive, it takes about 5 seconds at idle to build pressure and engage. If you give it the slightest throttle before engagement, it won't engage.
Also, as probably expected, the transmission hunts a bit with rough shifting.

Just got the transmission rebuilt in my truck and other then shifting hard sometimes it has been doing great, Hooked it up to the goose neck this evening and everything was fine then went to back it up and pull it forward and after a short distance the od light was flashing and when i ran a check on it it was p0720? The transmission has less then 1000 miles on it?!?!? 1999 Ford F-250 7.3 Automatic....

Is there some sort of reset to turn off the Check Engine light? I had replaced the TPS sensor, and after a day the engine seems to have stopped the high idle and returned to normal, and now it still has the check engine with the same error code, but the problem seems to be resolved. My previous post: [URL] .....

My 2009 F250 5.4 was throwing code P0442 - minor EVAP control system leak.
The first time it happened, the guy at the parts store checked it out, reset it, and said if it comes back, try replacing the gas cap.
The second time it happened, same thing.
I bought a Stant cap at my local parts shop, and had them reset it again. I don't like the Stant cap since it does not fit the retainer correctly, but it sealed fine.
However, the same code came back.
It took a smoke test to identify a leak from the vent tube on top of the fuel tank. The tube was replaced today.
If the code stays gone for a few hundred miles, I'm going to switch back to the original gas cap. I want to make sure the leak is gone before I change anything.

Started flaring between 3rd and 4th I changed the pressure solenoid and the direct clutch and no change. Flushed the tranny and changed filters and no change the oil is not burnt. When it flares it goes into a safe mode on the dash and will shift perfect through 4th gear no issues. I guess I've always know if it's bad it's bad but I don't understand why it works in a safe mode but slips in regular. Also if it is a bad tranny will a 3c2p-7000 work as a swap in my truck. 2008 6.4 4x4 ....

Last week I hauled my camper (2000 Thor Citation @ about 10,000 lbs) to Moosehead Lake. On the trip to and from I experienced a few problems. Tow/haul was engaged all three times. Trucks got just over 90,000 mi.
1) When shifting, the truck would occasionally stutter, like a gas engine when it misfires. Seemed like it would usually happen when transitioning from a slight down hill to an up hill.
2) Once, after a long up hill pull, as it crested the top, the truck slammed into the next gear, hard.
3)Once, going down hill, the trans wouldn't shift into O.D. until I took the rpm's up to 3000 then let off the throttle. No, I did not touch the brake prior to this.
Figure the tranny's gonna need a rebuild soon. What kind of upgraded parts does the wise and all knowing FTE wizards think I should be looking at? I tow the camper a lot during the summer so I want a trans that will hold up to the abuse. I'm probably stuck with this thing for a few more years.

I have a 2005 Ford 6.0L Diesel with the 5R110 transmission.
About a month ago, i started seeing some strange shifting issues with the transmission. While driving normally, it would suddenly hard shift (slam itself into gear), the entire truck would shake it shifted so hard. It would also cause the Tow/Haul indicator to start blinking. (my understanding is that the Tow/Haul light indicates an error code).
I drained/flushed the transmission, installed the larger pan/with the improved filter. I put Mercon LV back into the transmission (what type of fluid was in there before).
The problem still persists, and got a bit worse. The truck is almost un driveable at this point. Still getting Tow/Haul flashing messages. Can the error code be read by an standard ODB2 reader ?

So I scored a real deal on a set of Michelin on same size 17" OEM wheels that were taken off a brand new 2017 F-250 at about 100 miles. I installed them on my F-350 and had no faults show up. The tires had been marked as to which corner they had come off of so I put them on the same corners of my truck.
After driving about 50 miles I got a "Tire Pressure Monitor Fault" code. I pulled out my owner's manual and followed the relearning procedure exactly but I get the two beeps and the fail retry message from the left front. I have tried three times and get the same result.
Looking for info if the 2017 F-250 sensors are compatible with the 2011 F-350? Have I overlooked something? I habitually manually check my tires anyway, is there a way to disable the TPMS? Is it time for the dreaded trip to the dealer?

I have 2 issues and wonder if they are related. I don't have a CEL but I'm getting a P0442 DTC with my code reader - EVAP system leak detected
Also, my ESOF doesn't work. The hubs will lock manually. Can this be related?
I've already cleared the code and it came back. My ESOF hasn't been working for a while but I just haven't had the time or motivation to look into it until now.
I tried the HVAC Test and there may be a slow leak in the system. I can get the vents to switch from defrost to face vents but it switches halfway back to defrost, both are on at the same time for 20 seconds, then it recovers and goes back to the face vents.
My 4wd relays seem to work as well.

I recently picked up a 2005 f250 SD 5.4 4x4... I was having issues with sporadic shifting and wandering shifts while cruising around 100kph, scanned it and came up with p0721 OSS sensor circuit performance fault.
I checked the harness and all looks fine, now I attempted to remove the OSS at the rear of the tranny, got the 8mm bolt out however could not, for the life of me get the sensor out. I tried not to use pliers to twist the sensor or anything for fear of breaking the sensor off and having bits go into the transmission.

I have a 2007f550 auto trans with a flashing tow/haul light and a code of po791 coming up. Flashing light will clear in k/o position and remain off until placing selector in drive,after two feet or so of travel,an audible clunk and the trans acts like it is in third gear. Reverse is no change and highway will not shift into o.d. The iss "A" is listed as the culprit but ford doesn't list a iss a.

I have been looking for some information on 2004 Camry SE 4 cylinder. Last week it stopped shifting into OD. but it shifts good through first, second and third.... then it at 65MPH. I am tacking 3.5 Hundred RPM. I have a OBDii code of P0766, Solenoid. But which one.
There are three solenoids in the trans. (I have changed the filter and fluids about 3000 miles ago ) so now I believe one of the solenoids is bad. But I cant find out which one.

I have erratic changing of directions of the air control. It'll be on ac it will then change to feet or defrost. then stay on that for a while and flip again. It'll then stay on that one( usually vents). I'm guessing the selector switch or the vacuum egr valve.

My 1999 6.8 has developed a miss at low rpm lugging, so I checked on my code reader and it says the Fuel Volume Regulator Control has open circuit.
Well, I can't find anything on these forums or in my shop manual on a fuel volume regulator. Is my reader just using the wrong name?

I recently bought a 2008 F250 with the 6.4 diesel indirectly from a dealership. The truck itself has 220,000ish kilometers, but the engine (as well as the turbos) are Ford reman that had about 12,000km when I bought it and I have only put about 6500km on it. It is already leaking oil but that is for another thread.
The reverse sensors, steering wheel controls and part of the stock 6cd radio have never worked. The towing system has errors as well. The fuel level sensor often has problems reading the new level after I put in fuel, but that is always fixed by disconnecting the batteries and forcing a hard reset.
I figured the steering wheel/cruise control problem was due to either a broken clock spring and/or the brake pressure switch. I replaced both those as well as the airbag because the horn relay failed closed when I put it back in the wheel. It did not fix the problem. The steering wheel buttons still intermittently illuminate, but the radio controls and cruise control buttons do not function regardless. The truck isn't giving any codes either.
The towing system will activate lights and brakes on a trailer as well as set the gain, but it will not detect that it is actually hooked to a trailer. I cleaned the pins, but I haven't looked any further into it. No codes for this as well.
The reverse sensors/system does not work. It will lock itself in "off". I am guessing this is because one or more of the sensors have failed, but I am skeptical that it would be just that given the trucks other problems.
The radio does work, but the auxiliary input/mode will not work. I ran the diagnostics on the radio and on 'Test 1' I got "SELF FAIL B1342 ECU" and "B2477 CONFIG". I tried to clear the codes, but I can't. I think this means the radio is kill.

Traveling cross country & got a check engine light telling me "injector control pressure low". Replaced ICP sensor and injector pressure control regulator. Removed old one and installed the new one.
While looking for one of the nuts that attach the glow plug relay in the valley I found a small round part looks like maybe a valve seat. About 1/2" round with maybe a 1/4" four flute spline in the center. Has an o-ring on one end.
Is this something that followed the old ICPR out and fell off the end when It cleared the mounting hole? It looks like the ICPR would bear against this little thing.

My scanner reads P0001 Fuel Volume Regulator Control Circuit Open. My truck shuts down without warning, runs great otherwise. I've changed 2 grey CPS units and now have the Black IH one installed. What the Fuel Volume Reg.is? Is it the IPR on the HPOP?F250SD 7.3 225,000 miles.

I'm having an issue on my 2002 F350 7.3. Today I hop in it and drive off I notice my speedometer stopped working. My overdrive light on the shifter started flashing. The trans seems like its not shifting correctly. It will eventually shift into overdrive but not always. Also now when I start off my fuel gauge raises and when I come to a stop it drops all the way to E and causes the ding and fuel light to light up. I figured this was all due to the VSS being bad. So I drove over to Autozone bought another VSS and a cheap tool set and changed it in the parking lot. No dice. I do have a scanner to pull the trans code but its late and I just got home.

I have owned an 03 Excursion that I have had since last November that has started to feel like the steering is badly broken for a few hundred feet some times and then goes back to normal. It will do it some times after taking a corner and then suddenly there is a 1/4 turn play in the front and its wondering in the lane as I correct it back and forth and then it stops and goes back to normal. I've checked it and it all seems good and tight. The truck is stock height and has stock size wheels....
