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?

Nowadays it’s mostly because of space in an automatic transmission u can put up to 10 gears approx (Ford mustang, F-150 among others) which can be put in a “small space” due to not needing the big rods of the manual transmission to move from one gear to another.
