OK , Here is the deal . It is a transmission kick down linkage. What it does is enable your 3 speed automatic transmission to down shift from 3rd to 2nd when you are passing someone. Also known as "passing gear "By droping down one gear, you have alot more torque/power available for passing . You should adjust this linkage so it only kicks down when you have the "metal to the pedal and the thing to the floor" as Sally Field once said . If you are already going too fast, you won't kick down at all.
