FEH moving Forward when in Reverse

Re: FEH moving Forward when in Reverse
No codes that I can read with the SG. Don't know what the one-way clutch is.
Bill, thanks for the idea about the flight recorder, I'll ask when I go to the dealer next.
I did call Ford customer support and they seemed interested and assigned me a "case number". Supposedly someone will call me Monday and they will coordinate with my dealer to get this investigated.

So case is closed unless the problem reoccurs and I choose to have a dealer pursue it at my expense.

Re: FEH moving Forward when in Reverse
Just a silly question, but is your shifter super easy to move through the gears? Not totally related, but I had to replace my shifter cable (due to a rock jumping out in front of my vehicle But I had no park as a result of the damage. The shifter cable hangs low on the front of the vehicle and is only protected by a small metal guard under the plastic shroud. Not that you hit anything like I did, but if your shifter cable goes bad, it might cause some of these symptoms.
Perhaps you could have someone move the shifter through the gears (with brake applied) while you check the movement of the end of the shift cable. to see if it moves the eCVT lever.
just a thought

Chris,
I didn't realize that there's a cable involved in the shifting. I was thinking that the shifter was just a big switch with wiring connected to the eCVT, but apparently not.
The shifter is fairly stiff in moving through the gears, but I'll have a look for the cable at the eCVT end as you suggested.
I still think my problem was probably a computer glitch because it cleared up by cycling the ignition key several times. But having a mechanical cable running to the eCVT does make me wonder what the failure mechanism is. How could reverse be mistaken for forward within the eCVT?

Re: FEH moving Forward when in Reverse
Yea, it has both.
Reverse is all electric, though it has a detent in the transmission linkage. When that rock jumped in front of me, it broke my cable off in the D position. I could drive forward,,, AND revers without changing the transmission linkage because R is an switch below the shifter. I think L is a switch position too cause there is no low gears.
Your probably right about it being a computer glitch tho. I was just thinking that if the shifter and cable were not in sync, perhaps it was still in R even when the handle was in P.
Hope it doesn't happen again. May you have many trouble free miles!

Re: FEH moving Forward when in Reverse
Park has a parking pawl (pin) that goes into the gears to prevent the vehicle from rolling.
Everything else to best of my knowledge is electronic.
The gears are always in mesh to the wheels. Yes even when towing.
There is no true neutral, only simulated neutral.
I proved this by putting my front end on jack stands and running the car in neutral.
The wheels were powered very gently without the road resistance to hold them still.
Your problem does not surprise me.
The car did not get the signal to move in reverse.
The hand lever only moves the locking pin in park.
R, N, D, L are all done electronically.
Another proof a few have done is this:
While moving forward at highway speed, move the gear selector to R.
Absolutely nothing happens because of the computer logic.
