is the system of
gears and/or the hydraulic
system (called variously "hydrodynamic", "fluid" or "automatic"
transmission) that transmits mechanical power from a prime mover—such as an
engine or electric motor—to some form of useful output device, normally
rotary in form, and generally at a reduced rate of
angular momentum
but at a higher motive torque. This is primarily accomplished through
the utilization of
torque converter,
clutch and planetary gear sets.
