changing out transmissions

Same engine? That probably doesn't matter too much, as the 4.9 / 300 are the same bolt pattern as the small block. Flywheel would matter, but new ones aren't prohibitively expensive. I'm pretty sure the trans will fit, one big problem with that swap is always the clutch. Hopefully the generation 7 pedal set bolts right up to the generation 9 cab, and isn't the sort that is installed before the dashboard went in. The driveshaft is also of some concern, hopefully some combination of what you have, shaft and yokes will work. Otherwise, it is a lot of poking around scrapyards or having one made. I can't say if the ecm would miss the automatic or not, but I suspect it would be ok
