The Gearbox That Thinks For Itself — How an Automatic Transmission Works | Mech Cosmos

In this video we explain exactly how an automatic transmission works — from the torque converter that multiplies torque to the planetary gear sets that provide 10 different ratios in a package smaller than a shoebox. Every system. Every principle. Every number that matters.

At Mech Cosmos we break down the world's most fascinating machines and engineering systems — one topic at a time.
