It seems likely that some how the dealer is changing something they should not, possibly by wiping the memory and then not performing the drive cycle since the fsa didn't call for the drive cycle to be performed.
Like me! I've asked Thomas (the Ford dude on here) several times to find out what the official shift point should be after 12B37 and he can't seem to get an answer. Seems like a pretty simple question so WTF? My guess is some service depts. are doing something wrong but Ford engineering doesn't want to effectively call them out on a public forum.
