The display will show a wrench icon and check engine light. The transmission will suddenly downshift and lose power. The RPMs will either rise or remain the same but unable to accelerate. The wheels will intermittently lock up. This occurs at high speeds on the highway and on back roads at slower speeds. Stopping the tuck, shutting it off and turning it back on will "reset" and it will run ok but the timing between incidents is intermittent. There is a recall for this issue however the dealership (Greico Ford in Raynham) refuses to make the repairs, instead telling me this is no longer covered by recall: Transmission molded leadframe extended coverage [XXX] Today was the latest event, however this has been ongoing since December 2024.

Incident

May 15, 2024

There is an active recall for my specific year/make/model - yet I'm being told it doesn't apply to my vehicle - but my vehicle is absolutely having the exact issue described in the recall. How do I get this resolved? The issue is that my vehicle will unexpectedly downshift, (I believe into first gear, based on the RPM's that I get stuck at) almost always while I am driving at freeway speeds. When this happens, an orange wrench appears in my dashboard warning indicator for a brief moment, then I lose all gauges - my digital displays literally just turn to blank dashes as I lose power and the ability to accelerate. My gauges all drop to as if the vehicle isn't even on, my speedometer displays "--" and my RPM's remain at approximately 1500 regardless of whether I try to accelerate or decelerate. If I decelerate, because I'm in the improper gear for the speed I'm traveling - I will not be able to accelerate. The only way for me to resolve the issue is to try and find somewhere to safely pull over, put the vehicle in park, turn the engine off, wait a few moments and then restart the engine. This happens without warning and at random. Sometimes multiple times in a day, sometimes not at all for a couple of weeks. I don't understand how my vehicle is exempt from the recall. This has been ongoing for several months now. Thank you for your consideration

My truck is doing exactly what the recall on all the others. Check engine light on for input shaft speed sensor. Speed odometer quit working then engine light came on for speed sensor. Now when you drive on highway it will be fine then all of a sudden throw a wrench light and truck goes into limp mode and barely moves. You stop turn it off it resets but still isn’t right it doesn’t seem to shift at proper times seems to be shifting to often.
