Abstract: A work holder is provided for modifying an automatic transmission such that clutch pistons within the automatic transmission receive a unidirectional valve therethrough rather than the associated clutch drum as is typically the case. The work holder includes a base with a horizontal upper surface having a central disk which is sized to fit and retain one clutch piston to the base when the central disk is in one orientation and another clutch piston when the central disk is in another orientation. With the clutch piston securely attached to the work holder, a drill bit guide mounted on the work holder directs a stepped drill bit so that it may bore a hole through the clutch piston for passage of hydraulic fluid therethrough. Two drill bit guides are provided, one for each clutch piston, which each direct one of two of the drill bits to the appropriate location. Once the holes are drilled in each clutch piston a check ball and seat combination are located within each hole thus made.
