Dealership is trying to screw you over it sounds like try another place if you can. They probably cleared any stored codes on it, and are trying to run the warranty out.

what they think is overdrive is the car downshifting was what i was trying to say. you are, actually, 100% incorrect. OD isn’t an upshift at all. it’s no shift. it’s basically just slipping the tranny.

Overdrive is any gear under a 1:1 ratio. Of which most remotely modern cars have at least one gear like this some even two.
ex. A gear ratio of 0.999~:1 or lower would be considered an overdrive gear.
