Actually I just drive it in the highest gear already, which D=OD, your choices are D, 4, 1 and L. What it will do is shift into OD when it senses high enough speed & its steady, your RPM's will come down saving you gas. It does it even at low speeds--I like it--AND it works great, its all computer controlled with of course being effected by the gas pedal, unless you have a lead foot or not (like my wife_):lol: She likes to "punch it lets say", it takes off all right--sounds good to.
