bottom gear
Slowest transmission setting
Bottom gear is the lowest gear in a vehicle's transmission, providing maximum torque for starting from a standstill or climbing steep hills.
In British usage, it's synonymous with first gear: The lorry ground up the hill in bottom gear.
Figuratively, to be in bottom gear is to operate at minimal speed or capacity.
