+1 my 2012 is the same way. I love having the sport oriented suspension and steering while still utilizing 7th and 8th gears. And when I want sport transmission I throw the shifter to the left. I can't imagine they removed this for 2013

You might want to look some more if you are trying to get sport mode to only change the suspension and not the transmission.
