A transmission direct clutch drum removing and installing tool for use on a General Motors Corporation Turbo-Hydromatic 400 automatic transmission. The tool comprises a round plate platform base (20) and a spacer channel (26) attached to its periphery, each having an opening in the center. A plurality of legs (30), each having a retainer (34) on its lower end, are pivotally connected to the bottom of the base (20). A T-shaped operating handle slideably penetrates the opening in the base (20) and channel (26), and contains a leg directing expansion guide disc (40) on the end opposite the handle grip. Between the base (20) and disc (40) is a free floating locking disc (46) that assures the alignment of the legs (30) without binding or internal bowing. To operate the tool, the handle extended allowing the legs (30) to be grouped together and placed within the sides of the clutch drum. When the handle section (36) is pushed downwardly, the legs (30) are forced outwardly grabbing the sides of the clutch drum. Thus, allowing the operator to remove or install the clutch drum.
