So I just noticed this issue on a trip to Baltimore last night when trying to get out from in between two tractor trailers. I have never noticed this issue before. It is pretty easily reproducible. The car used to run and drive completely fine. The cam phasers went bad in 2020 and the dealer replaced them and did a bunch of updates. After the cam phaser replacement and flashings, the car drove like crap and would shift or "pulse" into 3rd gear 4 or 5 times. After months of them telling me I needed to have the fluids serviced etc, I finally found the "customer satisfaction" reflash Ford offers and after driving it 3 or 4 days, it seemed to be resolved (or at least similar to when I first bought the car).
Now it has 72,000 miles on it and is totally out of warranty. Here we are again, but this time an actually dangerous issue. If you floor it at 60 or more, the car somehow shifts into neutral while still showing it's in drive and then will continuously redline and rev limit until you take your foot completely off the gas. Then the car downshifts into first gear while you're doing 60, makes a super loud bang, then shifts to 3 or 4 different gears, flashes a warning to read the manual in orange, and sometimes a red warning. No error codes are present after this.
So does anyone (including Ford) actually understand what is happening?
Is it a programming issue? Is it a neutral out tsb? Is it a problem or error with the learned table values?
Can it be cured by just resetting your computer and relearning? Will a reflash from someone like gearheads cure it? Will the tsb cure it? Everyone seems to have a different opinion on what will fix the issue and what won't.
I can spend 1000 on a tune, 2,000 at the dealer to try the tsb, or trade the car in. None of these are guaranteed solutions and I don't like rolling the dice for thousands of dollars.
It's paid off, has a 5 star crash rating, and I was hoping to keep it for 10 years...
