Ask them if they checked the adaptation values for the trans. That's the way to tell if it's worn and in need of rebuild or replacement. If the adaptation vlaues are good, then you have another problem, probably the ETC and valve body which are notorious for causing the harsh downshift problem. You would be right to check the fuel trim adaptation values as well, as it's true that a going-south Air Mass Meter will also cause shifting problems.
