The contact stated that the vehicle was previously repaired under the federal safety agency Campaign Number: 26V237000 (Power Train); however, the failure occurred after the recall repair. While starting the vehicle, the transmission started out at 5th gear with the engine revving, and while driving at various speeds, the transmission slammed into gear before accelerating.

The vehicle was taken to the dealer, who determined that the lead frame and PCM were normal, but the transmission might need to be replaced. The manufacturer was notified of the failure by phone. The failure mileage was approximately 163,000.

I purchased my truck in XXX. Shortly afterwards as I was driving at approx 45 mph, the rear end just locked up and felt like something had snapped inside the transmission or transfer case. I had an extended warranty which Ford took full advantage of claiming that the rear end had locked up due to a bad 4 wheel drive switch and I knew I was being lied to. They got the extended warranty to pay for they're transmission leadframe recall that they didn't fix. They also added 4 degree pinion angle shims under my leaf springs and claimed that I put them on my truck and I did not, they did. They also lied to me and said they hadn't removed my transmission yet I could see fresh tool marks on every bolt on my transmission. They installed a thermal bypass valve in my transmission, I believe so that they could claim that I had installed aftermarket parts therefore ford isn't liable. Not long after Corning ford rebuilt my rear differential that had been destroyed due to the rear end lock up, I got a check engine light for turbine speed sensor fault. Corning ford denied any recall however bomarito ford in [XXX] confirmed that there was a recall for the lead frame that was issued 1 year after the truck was manufactured. Which is false because I bought the truck from a Chevrolet dealer in [XXX] and we went over all recalls and carfax online together and they printed everything. NO RECALL FOR LEAD FRAME OR TRANSMISSION. Corning ford employees were rude and had horrible attitudes towards me from the first visit. They claim to have fixed my vehicle but the rear axle housing is bent and I removed the rear drive shaft and placed it in 4 wheel drive and the vehicle wouldn't move indicating that the transfer case was damaged and they confirmed it should drive without the rear drive shaft but claimed there was nothing wrong with the truck. I had to spend my own money to replace the lead frame and I took it for the recall finally after it's 10 years old and t INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5

Ford finally sent me a recall notice just this year in May. I have called multiple dealers and Bomaritto ford in [XXX] told me 2 and a half years ago to bring my truck in and they'll replace the Lead frame free of charge however any dealerships I contacted in [XXX] denied any such recall. When I received the recall letter from ford it stated the transmission lead frame would be covered for 10 years or 150,000 miles. The truck was already 10 years old when I finally received a notice from ford. I ended up rebuilding the whole transmission myself and it cost me over $1500.00 in parts, not to mention I was without a vehicle for approx 2 months waiting on all the back ordered parts. The lead frame I installed was not a ford oem part. The service team in [XXX] told me either way, fird has to replace it with oem parts. I took it to crown ford in [XXX] and they refused to replace the Lead frame which had a check engine code as well. They claimed it was a software update was the problem. I believe that they deleted it from the tcm and ecu. Ford has done everything they possibly could to cover this up and they got the extended warranty to pay for the damaged rear differential which they used the old axle housing that was bent from the lock up and I have spent thousands of dollars in parts and alignments and the vehicle will not stay in alignment because of the damaged rear axle housing. The transfer case was never repaired or replaced also. They treated me completely horrible and lied about my vehicle ever having any recall for the transmission. They installed the 5 degree pinion angle shims to compensate for the rear axle shafts being twisted from the rear end locked up. Ford is not allowed to install them because it is a liability issue for them. They claimed that they were already on my vehicle which is a complete lie. I wouldn't even know where to get them since I can't even locate any online or at any auto part stores... INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Our 2016 F-150 experienced a dangerous transmission sensor failure (Ford Service read code P0722). Ford's 26S28 safety update was performed prior to this, but the physical lead frame has now failed. Ford Corporate (Case #CXH-09620415) is refusing to replace the defective safety component under companion program 26N04 because the vehicle threw code P0722 instead of the four codes arbitrarily listed on their bulletin, leaving a known mechanical defect active on the road. In this case we pulled out from a driveway onto a road and the truck stayed stuck in 1st gear or was in limp mode and the check engine (wrench icon) lit. Had this been a busy intersection we could have been hit by another vehicle. With this part failing, which is known to cause other similar problems, the truck can shift erratically or get stuck in one gear or downshift or suddenly go into limp mode from any speed. Any problems associated with the defective lead frame should be fixed not just those that throw certain codes.

I am reporting that the Corporate Ford Company is knowingly requiring a software update that minimizes a safety hazard instead of eliminating a safety hazard (the federal safety agency Recall 26V237). Here are the facts: ---Lebanon Ford service said that they cannot tell me what the software update 26S28 will do to fix the danger of driving my vehicle. The mechanic (Michael) said that the software update is meant to fix the transmission molded lead frame, but that it does not. My research about this software update states that the truck will unexpectedly downshift to 4th gear (instead of downshifting to 1st gear without the update). This downshifting issue poses a danger to people driving on the highway! Consider trucks suddenly downshifting to 4th gear in front of you on the highway (some towing)! Ford Recall: 26N04 is a fix that will eliminate danger, but Ford is NOT fully implementing it! Molded Lead Frame Failure The Issue: The internal wiring harness (the lead frame) holds the speed and temperature sensors. When it fails, it sends bad data to the computer. Symptoms: Erratic shifting, a wrench light on the dash, or a check engine light with speed sensor codes. Unexpected Downshifts (Recall 26V‑237) --THIS IS THE SOFTWARE UPDATE THAT DOES NOT SOLVE THE DANGEROUS RISK. On XXX, Ford did NOT complete the Recall 26N04 (Ford #), only the federal safety agency 26V237 software update, which does not eliminate dangerous driving on the highway. I am attaching the event information that I gave to Lebanon Ford at the time of service. ALTHOUGH THERE WAS NO CRASH AND NO CASUALTIES, I CANNOT, IN GOOD CONSCIENCE, DRIVE MY 2016 FORD F-150 ON THE HIGHWAY BECAUSE FORD IS ONLY LESSENING THE SYMPTOM, WHICH IS STILL A DANGER TO PEOPLE. FORD CAN FIX THE PROBLEM TO ELIMINATE DANGER, BUT THEY CHOOSE NOT TO DO SO.

Ford mailed me a XXX Customer Satisfaction Program 26N04 letter for my 2016 F-150, VIN [XXX]. That letter offered a one-time, no-charge replacement of the transmission molded lead frame if the dealer determined replacement was needed, and it described a malfunction indicator lamp and/or wrench light when that part fails. My truck did exactly that. It stored P0715 and P0717, went into limp mode, and the wrench came on. Titus-Will Ford in Tacoma confirmed the turbine speed sensor is part of the lead frame and replaced it (part AL3Z-7G276-D). They denied 26N04 because those codes are not P0705, P0706, P0707, or P1702 — a code list the customer letter never disclosed. The failed part is the part named in your letter. The symptoms are the symptoms named in your letter. I paid invoice XXX dated XXX. The lead-frame line was $1,630.02.
