I had the same issue, logged about 2200 miles and shift was very harsh I recently got a new set of tunes with softer shifting and it seems fine so far.
I don't know what happened but I didn't get a cel since the re flash. I don't know if it has anything to do with it but I recently ordered a catch can.
I am modded but I just re flashed to stock and the code didn't come back on hopefully it stays that way, if it does I will have to schedule an appointment with the dealer and see what happens. Thanks
I did a similar setup but the engine bay does get really hot and I found that the intake was sucking in hot air so I want back to the drawing board and constructed a full enclosure that seperates the incoming air from the hot air.
I have this same problem since my vehicle was 4 months old, I'm now at 4,700 miles and can't afford to leave the radio on without the vehicle running. 2016 Ford Edge Sport
I thought the same thing but somehow it feels like it holds the gears longer but then again I only drive it around the block a few times. Oh well I'll update as I drive more
