Variations in speed does not matter, it will be the same until I reach 85 km/h. Then the engine speed will be greater than 1700 rpm and the lock-up clutch is continuously engaged.

The workshop said there was no new software for the car, and therefore assumed it had the latest versions. They also said the transmission was flushed (11 liters of oil was used)
are you sure it is not actually dropping down a gear and then changing up a gear again ?
