Overdrive in the city probably will not even activate at slow city speeds so I would say his statement to not use overdrive in the city is not a valid statement. Overdrive is like having a 5th gear added to your already 4 speed transmission. It won't even shift into Overdrive until you reach a speed of 50 to 60 MPH. Do you drive 50 or 60 in the city? So just leave it ON. Now for Highway driving I would use it except for mountain driving, then turn it off. In mountains your Transmission could "HUNT" , shifting back and forth, in and out of OD and in and out of HI, thus building unwanted heat in the tranny while you are climbing. Now going down hill you turn OD OFF and downshift the tranny to use the engine compression to hold you back, thus saving your brakes.
this is my understanding of how OD is to be used.
