Suddenly bad noise from 60 km/h in the 850 2.0 T5-Italo

Hej all together, I need advice… 20 motorway ride, this morning… permanent, slightly “sleep/striking”? Noise, acoustically located from the direction of the central ventilation grid in the cockpit and coming up from below. Otherwise everything normal, gas acceptance, gear change (normal operation/not sport) inconspicuous, brakes too. Highway ride, this afternoon, still the same noise… 2 kilometers with 180 km/h, further with 130 km/h, then speed up again and at 155 km/h it beats the front i Somehow metallic, I would say and then continue, rhythmically and clearly loud. At the subsequent braking, it rubs on the front axle and it smells, slightly but nevertheless well perceptible, like hot brake discs/covers. The noise, becomes slower and quieter at decreasing speed. At 60 km/h arrived on the stand strip, it is gone. The vehicle can be switched normally, in all modes. On the stage, an extensive visual inspection shows nothing, the steering parts are Mechatronix and his helper Schrauberix say, according to hearing, there is gas on the stage and switched on…: a transmission damage. Can this be and after hearing be determined safely? And what kind of automatic transmission is installed in the T5 2.0 with the TSN 738? Have invested a lot in the moose in the last 3 years and would like to, if “necessary”…, look for a good, used transmission and then have it installed. Greetings, Volkersson
