If you are going 30 mph, and you put the petal to the floor, it should kick into third gear, but if you put it to the floor and then into KICKDOWN, it should shift into second gear and stay there until about 60 mph.

A better way of doing it might be to drive at 50 mph, and then mash the petal all the way down (past kick-down), then it should rev into 2nd gear, and you should really take off.
