Technical term = TAPS which is Transmission adaptive pressure
To reset = the battery can be left un-hooked for an hour, or it can be reset with a scan tool.
You probably won't know the difference if it was done or not. Unless it adapted to a really bad transmission previously. It will adapt on its own whether you reset it or not. Resetting it will start it from scratch.
Honestly if the shop is like you say it is, I'd be more concerned with things like, are they using fender covers to prevent scratches, are they keeping things clean, etc.
