tramsmission gm powerglide - super case w/chevy bell housing and bearing for tramsmission gm powerglide output

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.
