Morphology
The phrase is a straightforward adjective + noun composition: 'automatic' (functioning with little human input) modifies 'transmission' (gearbox), so the meaning 'a gearbox that shifts gears automatically' is directly derivable from the parts. This follows common noun phrase patterns and has clear cross-linguistic parallels (e.g., Spanish 'transmisión automática'), so a B1 learner who knows both constituents will understand it.
Etymology
The noun automatic transmission comes from a simple idea: automatic means it works by itself and transmission is the part that sends power from the engine to the wheels. So it refers to the car system that 'changes gears' for the driver, and the driver does not have to shift manually.
