Why do automatic and manual cars have different types of gears?

171 views

A manual transmission is from what I understand just a set of gears on these two lil lines that connect and disconnect from eachother with the clutch, whereas an automatic transmission has a whole different thing with planetary and sun gears and stuff. My question is, why? Can’t the ECU just take a normal manual transmission gear mechanism and shift it as if a person were doing it; why do automatic cars utilize this whole new gear system?

Automatic transmissions are more efficient in one configuration while a manual configuration is more efficient in another. If you tried to turn a manual into an automatic, you would get a sucky automatic.
