2006 Toyota corolla does the over drive light comes on automatical
You might be hitting the switch on the gear shift by accident.
NO. Not automatically. When you have your hand on the shifter, the O/D on/off button is right below the button to push to shift out of "Park" and with your hand on the shifter your thumb will have a natural tendency to be right on the O/D button and can very easily be pushed without you even realizing it. I have a 2006 Corolla so I am very familiar with the car.
