Gearshift was a Republic clone trooper who appeared in Season 2 of Star Wars: The Clone Wars. He took part in the Second Battle of Geonosis as a member of the clone army's 212th Attack Battalion. Like all other clones in the series, he was voiced by Dee Bradley Baker.
In the episode "Legacy of Terror", Gearshift joined Obi-Wan Kenobi and Anakin Skywalker on a mission to rescue Luminara Unduli after she had disappeared into the Progate Temple. Within the catacombs beneath the temple, the team were attacked by a horde of undead Geonosians. Unable to call for reinforcements due to interference on their comms, Gearshift and another clone trooper were ordered to head back to the surface to summon aid. Not long after separating from the Jedi generals, Gearshift and his comrade were attacked by Geonosian zombies and killed. Obi-Wan and Anakin later found Gearshift's body, his neck broken.
