Punto Selecta Pfeifit while driving

Hello all, so I recently bought a Punto selecta with 60 Ps. has automatic gearbox, because I am not allowed to drive a manual gearbox due to my disability…year of construction is 98 and the car has 95000 Km on it… I’ve been driving the car now for about 2 weeks and I noticed that when driving a whistle search is present, it doesn’t bother me so much but I hope that’s nothing bad…gear is really clean, no problems, the car is general se hr cared for.. I hear the whistle search especially at 40-50 km/h afterwards less…Unfortunately I did not notice it during the Porbefahrt… I had before a Renault megane which I sold because of transmission problems…he had not switched clean at all, at punto I notice it even net at the switch… well I hope it is not bad… Could someone tell me something about it? Thank you Greetings
