Overdrive is an extra gear assembly in the transmission that allows the engine to run at a lower speed (lower RPM) when you are travelling at higher speeds on the highway or freeway. For example, if I am driving my 1995 Explorer at 62 mph in drive, the engine runs at 2800 RPM. If I am driving at 62 MPH in overdrive, the engine runs around 2100 RPM.
Downshifting
Driving on lower RPM's will reward you with higher gas mileage in addition to putting less wear on the engine. So, low RPM will be cheaper in the long run.
Lugging engine? Should be in a lower gear to prevent engine damage
I have a 1994 Isuzu Trooper and it has issues upshifting at lower speeds. How do I check the fluid level in the transmission when there is no dipstick?
Engine Brake: One way to reduce speed by shift down the gear from Higher to Lower (Eg. Driving with 120 km/h with 5th gear, by turning to Engine Brake it reduce to 4th gear that make the speed is reduced) It's very helpful when driving with high speed.
Most cars today used dual cam or more for power efficiency and lower gas emission for longer mileage.
No. It is used to lower engine emissions.

The diagnostic port on a 1995 Isuzu Rodeo drive is located on the lower kick panel on the driver's side. It is just below the left spark plug.
