Deciphering the Mechanic's Mystery
3-on-the-tree is an idiom commonly used in the United States to refer to a type of manual transmission gear layout in older vehicles. With this idiom, the number "3" represents the number of forward gears available, while "on the tree" refers to the location of the gear shift lever on the steering column. This idiom originates from the physical setup of the gearshift mechanism, where the lever is mounted on the steering column itself, emerging from the dashboard.
