SuperCase® Transmission Case

The SuperCase is an SFI certified transmission case for Powerglide and Turbo 400 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 or Turbo 400 components.

Performance Automatic SFI Ford Bell Housings

These SFI-approved bellhousings eliminate the need for a flexplate shield and bolt directly to the C-4 transmission which uses the small 156 tooth flywheel and the short 5.6” 10-1/2 bolt circle converter. A spacer ring is available for use with the 164 tooth flywheel and taller 5.9” 11-7/16 bolt circle C-4 converter. Adapter rings are also available to bolt the bells to the pump of a T-400, T-350, or Powerglide transmission with a unique method that assures perfect concentricity of the bell to the pump. Ford Bells are available for the Small Block, 429-460 Big Block and 427 FE engines.
