Just a quick question that is probably really obvious but, if you don't ask, you'll never find out.
I have an 89, 7MGE Auto. On the gear stick is a button marked OverDrive. Now, as far as I can work out this changes the gear ratio but what is it actually for and when would I ever use it.
Also, what is the power button for? Is this traction control?
Thanks in advance and sorry for being stupid
