In an automotive context, "tranny pacs" (more formally known as ) are the critical internal components of an automatic transmission responsible for shifting gears . These packs consist of a series of alternating friction and steel discs stacked within a drum. When the transmission’s "brain," or valve body, directs hydraulic fluid to a specific drum, a piston squeezes the pack together. This pressure locks the discs, engaging the corresponding planetary gear set to change the vehicle's speed or direction.
