Noise when switching- C70 Automatic

Hello Together 🙂 I noticed today with my C70 T5 automatic (2007, 95,000km) that he makes a “scratching” sound when he first(!) switches into the second gear after the engine start, then nothing can be noticed anymore, he switches as always, no matter in which gear. Even if I start again from the stand and he switches into the second gear everything is good. If I repeat the whole thing every time and turn off the engine before, it is again to hear this noise when first switching into the second gear, then it is gone again… I hope you can give me some advice!
