ATI SuperCase TH350 Transmission Cases

The ATI SuperCase TH350 transmission cases are SFI-approved for competition use. The case, bellhousing, and tailhousing are cast from 356T6 cast aluminum. Developed to eliminate all weak points found in the original GM design, this rugged assembly features a steel safety inner liner that weighs only 29 ounces and eliminates the need for any external shields. In addition, the SuperCase features a removable bellhousing that bolts directly to the transmission case instead of the pump bolt locations and has been engineered to accept all internal Turbo 350 components.
