Because the auto and engine transform speed, the distinction between the pressures modifications, resulting in various sets of valves to open up and shut.
An early patent for the automatic transmission was granted to Canadian inventor Alfred Horner Munro of Regina in 1923.[20] Becoming a steam engineer, Munro designed his gadget to work with compressed air rather then hydraulic fluid, and so it lacked electric power and never ever identified commercial application.[21]
