We’ve got a 2022 Fiat Ducati auto. I tend to use automatic most of the time and only occasionally the sequential mode (I think that is the term Fiat use). But I’m never sure how or when you should engage sequential mode if driving in auto or vice versa. Do you just freely shift the gear stick to the left (or right) or only change from one to the other when the vehicle is stationary? I tend to find it easier to use sequential mode if going down a steep descent as it’s easier to control the speed.
