When you put the transmission in S, then use either paddle shifter, you are in fully manual shifting mode. The only thing it will do on it's own, is downshift when you slow down or come to a stop. If you are doing 20mph in 3rd gear, in S, after using the paddles at least once, it will not downshift to 2 or 1 when you floor it. If yours does not behave like this, I don't know what to say, haha.
