ATI aluminum TH400 SuperCases feature SFI certification and a bellhousing. Developed to eliminate all weak points found in the original TH400 case, the rugged SuperCases and bellhousings are SFI-approved for competition. 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 TH400 components.

Features:

Heavy-duty 356-T6 cast aluminum case meeting SFI 4.1 specs with no internal or external shield needed
Made in the USA and machined in-house at ATI using only two fixturing set-ups to provide optimum accuracy
Accepts OEM pans, extension housings and 99% of all stock internal components
 
CNC machined minimum depth valve body passages yield extremely fast transbrake releases and quicker shift times
Accepts all current ATI Super Bells for many engines and other bells on the market
Features additional center support lugs to provide additional 2nd gear strength, with a modified pressure plate supplied
 
Provisions for three extra bolts added to help secure the center support and intermediate pressure plate
Increased thickness extension housing/output shaft bearing area provides extra support for 4x4 units
Roller bearing for output shaft (bushing available by request)
Cooler lines are 1/4" NPT to accept PG quick-connect lines and other popular cooler hoses and fittings
