If you look in the owner's manual of a car with an automatic transmission, you might find that the manufacturer says changing your automatic transmission fluid is not necessary.

The differential helps distribute power from the transmission to the driven axle, and it also allows the wheels to operate independently from one another.

A car's engine generates power, which is then passed through the transmission and sent to the wheels.

Many drivers prefer automatic transmissions that take care of shifting for them, but while they can make driving easier, they can also be problematic.

Most vehicles are manufactured with manual transmissions as a standard feature, with automatic options offered as an upgrade.
