B58 squeak - faulty tensioner/slipping belt

Sup everyone!

I got my B58 2 weeks ago... First off, what an amazing car. I didn't think they can make it any greater and they did.

So now onto my problem. When I start my car I let it idle for about a minute or two. When I start driving, the first shift from first to second gear there's a squeak that occurs or you can hear the gear going into place like a tight shift on a MT. This only occurs on the first shift. Never happens afterwards. Also when in sports mode, the car shifts a lot rougher than usual as if the gears go in just on time. I have an 8 speed AT.

Has anyone experienced something similar? I've got an appointment at bmw on Thursday.
