slushbox

Definition

Synonym of automatic transmission.

Etymology

From slush + box, in reference to the fluid-coupling action of the torque converter. A popular notion portrays this action as "slushing around" that involves greater power losses than with manual transmissions, although the notion is a comic exaggeration.
