I am waiting on my Silver Graphite and never had an auto trans. with overdrive. What does it actually due when you shift into overdrive? I'm sure it is only used out on the open highway. Does it help with mileage?
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.
