Currently my truck is under a safety recall to update the new software on PCM for intermittent down shifts at any speed. Also there is a molded leadframe warranty extension. I'm thankful I haven't experienced the downshift to 1st. But have noticed it down shifts on highway from 6th to 5th to 4th and back up. Also hesitates violently when trying to pass or accelerate. Laird nollerf3ord in lawrence,ks is doing update on PCM monday sept 16th. My VIN is included, but they say they have to do a diagnostic and can only replace leadframe if certain codes are related. I personally think the transmission moulded leadframe should be replaced and than update PCM after. From what I read the sensors are the problem regardless of the software update. If my VIN is on the field service recall and the safety recall. Both should be done free of charge parts and labor. Regardless of the codes. Its fords [xxx] up. And many more accidents will happen if this isn't made a priority. I'm seriously scared to drive on the highway knowing anytime it could downshift into 1st gear. I read reports even after the update still have same problems. It's the leadframe people. I'll see how the software update monday effects the performance of my 5.0. Fingers crossed.

"2011 ford f150 lead frame in transmission recall'. I was driving down the interstate when my speedometer dropped to 0, my mileage indicator was showing all dashes ------- and the transmission was stuck in gear someone between 2nd and 5th and my truck started slowing very quickly on its own. I pulled off to the side of the road and disconnected my battery to see if it would reset the readings. Which was unsuccessful. After calling ford directly I was told my VIN # was not included in the recall that was noted in some other research I had done. I was told in order for it to even be considered it had to be diagnosed at a certified ford service station. I took my truck in today and was told that it is the exact issue that was in the recall but my VIN was not covered under the recall, even though my truck was the same exact year and manufactured in the exact same place where some of vins were recalled. This is a very dangerous issue and I am grateful I was not rear ended on the interstate as a result of the sudden drop in speed. I want to be included in the request to have ford broaden the recall that obviously my truck should be included in. If you need additional information please don't hesitate to reach out.

Our ford f150 has manifested several dangerous factory malfunctions as other vehicles with the same make, model and year. There are at least 4 ford recalls / customer satisfaction program extensions that our truck should be entitled to but isn't. We need help with getting ford to cover the cost of repairing our vehicle under at least one of the following recalls: ' recall number 16v24800 power train automatic transmission ' recall number 11v582000 power train automatic transmission ' recall number 12v190000 power train: auto trans: control module (TCM, PCM) ' recall number 10v659000 structure body (internal short / fire hazard) ' customer satisfaction program warrantee extension 16s19 we are forced to keep our truck off the road until we can afford a few thousand to replace the powertrain control module software, lead frame and possibly transmission. The truck spontaneously shifts into lower gears when driving at about 20-55 miles per hour. This causes the truck to hesitate in the middle of the road when driving. It simultaneously makes a 'honk' sound. There were a few occasions where the truck shifted into park when I hit the breaks or it shifted into reverse when I intended to go into drive. Clearly issues with the transmission and the vacuum pump pose serious safety hazards to our family and other people. We would greatly appreciate help in getting ford to extend some of the manufacture warrantees and recalls to our ford f150 so that we could return to using our family/work truck safely. We thank you in advance for any good advice or help that you may have to offer.
