Upon arriving at the temple, the group soon found the dead body of a clone trooper who had accompanied Unduli as well as the Jedi's lightsaber. Intent on finding Unduli, Skywalker, Kenobi, Cody, Gearshift and the other trooper entered the caverns through the temple's entrance, using lightsabers and headlamps to light the way. While approaching farther under the temple, Unduli contacted Kenobi and hailed him not to follow her. Kenobi, however, insisted on searching further for the Jedi Master. Soon after Gearshift and the group encountered undead Geonosian zombies and were unable to kill them. Soon several troopers were killed and Kenobi ordered a retreat. After taking down the tunnel's support, Kenobi tried to contact Mundi via comlink for reinforcements. Because the group was too deep underground to get a signal, Kenobi sent Gearshift and a fellow clone back to the surface to contact Mundi. Gearshift and his comrade were soon surrounded by undead Geonosians and quickly killed.
Gearshift obeyed the orders given to him by General Kenobi. He was glad to get back to surface when ordered so, because he found the Progate Temple's tunnels creepy. In combat he used a DC-15S blaster and wore orangePhase I clone trooper armor.
