SuperCase® Transmission Case

The SuperCase is an SFI certified transmission case for Powerglide, Turbo 400 and Turbo 350 transmissions. The case, bellhousing, and tailhousing are cast from 356T6 cast aluminum. Developed to eliminate all weak points found in the original GM transmission cases, the rugged ATI SuperCase and bell housing are SFI approved for competition, and feature a steel safety inner liner that weighs only 29 ounces—eliminating the need for any external shields. In addition, the SuperCase features a removable bell housing that bolts directly to the transmission case instead of the pump bolt locations, and has been engineered to accept all internal Powerglide, Turbo 400 or Turbo 350 components.

ATI's Direct Fit Bells feature a machined indicating
lip to ensure proper location on machined OEM cases
Direct Fit SFI Bell Housings
The perfect option for racers who prefer to run an OEM case. These new bellhousings are SFI 30.1 certified and are made from 356-T6 permanent mold cast aluminum. All ATI bellhousings are made in the USA. Our Direct Fit Bellhousings are available for the T350, T400, Powerglide and the Metric T200. The Standard version is designed to bolt on to the face of the pump and the case finish is not as critical. The Direct Fit version is designed to actually indicate on the outside diameter of the pump and precise machining is required. ATI can prep your case for you if ordering a Direct Fit Bell. Consult your Sales Technician for more information.
