Hopefully some 370 auto box owners can fill you in on the details but as someone who has always had manual cars for over 2 decades and am now in an auto I'd say you have to really give it a try.
Personally I am loving it in my M135i and don't miss doing manual changes with a clutch at all. Makes the daily drive to work feel effortless and when I want to go full throttle I can use the paddles if I like for lightning fast gear changes.
