Gearshift

Transmission was the Meta Ability used by the second user of One For All and later inherited by Izuku Midoriya.

Description
Transmission allows the user to change the speed at which things accelerate through space. The user may choose to enter different "gears" to increase the speed a given object has. These gears are First Gear, the base speed that is activated upon using Transmission; Second Gear, Third Gear, Top Gear, and Overdrive, the final and fastest speed.

Trivia

 * Transmission is one of the oldest known Meta Abilities in the series along with One For All, All For One, Life Force, Spearlike Bones, Fa Jin, and the unnamed luminescence Quirk.
 * The name of one of the "gears" of Transmission might a reference to the British TV Show , due to the Meta Ability and the show both being themed after cars.
