Drive it, it needs to relearn everything, recalibrate the computer memory. I don’t remember what the term is for this.
Just take it for a regular 15+ minute drive around town at various speeds and gears, and then take it out on the highway at 60-70 mph and drop it in to 6th gear for 5 minutes or so and then coast (clutch in or neutral and no brakes) to an almost full stop off of an exit ramp. You should be good.
