Abstract
A method and apparatus for assembling a part, such as a spool valve into a bore of a body, such as a transmission valve body. A gripper tool attached to a robotic arm supports the spool valve with a light vacuum pressure and maneuvers the spool valve, aligning it with the valve bore. The gripper vacuum is perturbated to allow the valve to be properly aligned with the bore.
