What you refer to as George overdrive is known in the trucking industry as Georgia overdrive. It is going downhill with your truck out of gear. This is gone down grades to allow the truck to accelerate beyond the normal top speed of the engine in to gear without damaging the engine.
You use an overdrive when the engine is not straining ,i.e., the road is not going up but rather going down, or your car is not loaded with heavy weights like passengers or goods, and you want to save gasoline.
This can be caused by anything from a bad sensor to transmission going bad. A transmission mechanic can check for engine codes and other tests to verify if it is a simple fix or major repair.
check your tire balance or you might need an alignment
It is not, but the engine works harder. You generally want to keep the RPM's as low as possible while driving. If you are going to be driving for a long time at the same speed, then it's better to enable overdrive no matter how fast you are going. Not only will your engine last longer, but you get better fuel mileage!
Going up hills doesn't allow engine to "lug" and overheat Going down hills supplies engine braking for safety and will prevent brakes from fading and overheating
Every vehicle has warning lights to inform the driver of things going on. The check engine light comes on because there is something going wrong with the engine.
If the check engine light is blinking that means that an engine cylinder misfire has been detected
The overdrive should be switched off when you want to avoid unneccessary shifting. If you are driving on a hilly road, the vehicle will shift out of overdrive going uphill to maintain speed while pulling the vehicles weight up the hill, and shift into overdrive going down the hill to save fuel when additional engine power is not needed. When towing with an automatic transmission, the vehicle may tend to repeatedly shift in and out of overdrive due to the added weight. In scenerios such as these, you should turn off the overdrive to avoid the unneccesary shifting which puts more wear and tear on the transmission.
