Ok , so can someone please explain the pro's of having the overdrive on permanently? all other cars that I have owned in auto, overdrive was something you had to shift into. my understanding of overdrive is that it's good for hwy driving?? so .... if that is correct, then why does the focus come with overdrive automatically on?? ( YES, i know there is a button on the shifter to turn it off, but you need to do it every time :unsure: ) i drive in the city and TRAFFIC 90% of the time.

Does being in overdrive in traffic affect gas mileage / wear and tear??

oh it's an 02 Wagon with the Zetec
