    I have a 2021 F350. When pulling a trailer connected to the bumper or 5th wheel hitch I have an issue with the downshift when rolling to a stop. This does not happen every time I stop but when it does, I am pulling a trailer in the tow/haul mode. The downshift happens when the display shows the transmission already in first gear.

    I took it to the Ford Dealer and they reprogrammed/updated the PCM on the transmission and felt it would be working normally now. No faults or codes were noted. I still have the same issue and they are puzzled. and asked me to return it so they can look at it again.

    Anyone else have this problem or one similar?

    Hook up your trailer, drop by and have them hook up the black box/flight recorder and take a drive to duplicate the issue. Only way to solve I know of.
