ATI SuperCase Powerglide transmission cases feature SFI certification and a bellhousing. Cast from 356T6 aluminum, they were developed to eliminate all weak points found in the original Powerglide case, the rugged SuperCase and bellhousing are SFI-approved for competition. They feature a steel safety inner liner that weighs only 29 oz., eliminating the need for any external shields. In addition, the SuperCases have a removable bellhousing that bolts directly to the case instead of using the pump bolt locations. They have been engineered to accept all internal Powerglide components.
