ATI Turbo 400 SuperCase

High-Performance Transmission Case

This cast aluminum Turbo 400 SuperCase from ATI has been in development for over 2 years! The SuperCase is designed and machined 100% at an ATI plant and cast in the USA. The TH400 SuperCase has improved fluid pathways to assure better performance while on the street or at the track. Each case is CNC Machined on a 4-Axis Horizontal CNC Machine which allows for minimum depth valve body passages which yield extremely fast transbrake releases and quicker shift times. The SuperCase will also accept any of ATI's SFI bellhousings (Chevy, Ford & Mopar), along with the Reid bell (requires slight modifications) and Browell cans.

Each SuperCase is a Heavy Duty 356-T6 sand-cast aluminum case and meets SFI 4.1 & 30.1 specs with no internal shield needed! Accepts OEM transmission pans, extension housings & 99% of all stock internal components. Provisions for three extra bolts were added to help secure the center support and intermediate pressure plate. Increased thickness extension housing/output shaft bearing area provides extra support for 4WD units. There is an included roller bearing for the output shaft. Cooler lines accept PG quick-connect lines and other popular cooler hose fittings.
