So when should overdrive be on or off?

It means the same thing in auto and manual transmissions, they both have a high gear that is overdriven, or less than 1-1. Normally high gear will provide a 1-1 ratio, when you overdrive it you run say 3/4-1 so the engine rpm is reduced to conserve fuel.

Overdrive is an oversized gear that causes the engine to operate at a low rpm and its so large usually that even cars with alot of torque have trouble accelerating quickly in this gear. Never pull anything in this gear as your motor will be under way to much strain. It causes the motor to have a larger bind on the crank shaft, and it requires more force and a bigger explostion from the cylinders to move it. Ive seen a moron which will remain nameless ;) "they know who they are" j/k blow a head gasket and almost blew up more,... they didnt even realize that when the motor pings from detonation... its bad..
Supposedly... the overdrive gear is so large that the motor will never reach the end of it... but I dunno... and endless circle that is physical, and fits in the transmission ;)
Foremost its a highway gas saver, for when your cruising and dont need to move the gas pedal, and going faster isnt top priority, or pulling,
Its the same in a standard car..
some have 1-4 plus overdrive
some have 1-5 plus overdrive
and alot of other combos..
less power used for coasting in overdrive
more used for acceleration
more used for pulling...
its only for cruising

Overdrive in a manual or automatic transmission is that point where the gear transmission system moves in tandem with the cars engine power. After engaging up to ( eg gear NO. 5 ) the available transmission gears, to enable the car give you maximum speed, the manufacturers enable the transmission system to override the normal gearing ratio to power ratio.

Overdrive refers to a gear that is less than a 1 to 1 ratio.

with an overdrive you got a torque converter clutch and when its engaged you are more like coasting and it saves gas,when you go on the interstate put it in overdrive and set the cruise and you save gas cause it takes the strain off the motor and trans.

After you have reached a high cruising speed, overdrive maintains it without using up a lot of gas.

Overdrive is an extra (high) gear for highway traveling. It saves GAS!

It shifts into a higher gear, therefore getting better gas mileage.
Never use overdrive while towing anything.

Its basically another gear. If you need extra power, then you shouldnt be in overdrive.
