What is4 speed automatic with overdrive?
A 4-speed automatic with overdrive in the true sense has 5 forward gears, 3 being a lower output speed than the engine RPMs putting out higher torque, 1 being a 1:1 ratio where the wheels are spinning as fast as the engine, and 1 that has a high ratio, spinning the wheels faster than the engine putting out low torque …

Which is better 4 speed or 5 speed transmission?
More than just helping with accelerating, having more speeds helps with fuel economy. At any given speed, a transmission with more gears is better able to let the engine stay at a more efficient speed. So all things being equal, a five speed will be better at putting power out and more efficient while doing it.
Should overdrive be on at all times?
You should drive with overdrive on almost all the time. It provides many outstanding benefits such as lower fuel consumption, extending engine life, producing less noise, and much more.
