The automatic transmission is a complicated piece of engineering for the ordinary person to understand.
My best advice would be to take it to a specialist for any servicing or maintenance.

The key difference between a manual and an automatic transmission is that the manual transmission locks and unlocks different sets of gears to the output shaft to achieve the various gear ratios, while in an automatic transmission, the same set of gears produces all of the different gear ratios.
The planetary gearset is the device that makes this possible in an automatic transmission.
