Auto Overdrive (AODE) is a type of automatic transmission (the part of a car that helps it switch between different speeds). It is similar to other automatic transmissions, but it is made to be more efficient. What this means is that it helps a car use less fuel and save money on gas. It does this by using the right gear at the right time when the car is driving. So, when you are driving, the AODE will shift between gears depending on how fast you are going and how much power you need. This makes it easier to drive and also helps your car save fuel!
