RTS Transmission, SuperMax 400 Transmission Case, TH400, Aluminum, SFI Approved, Each

RTS SuperMax TH400 Transmission Case RTS SuperMax 400 transmission cases are a street/strip version of the TH400 aftermarket SFI transmission case. The bellhousing is not included and must be purchased separately. A direct replacement for the GM case, RTS cases use a permanent mold casting to increase the case wall thickness, making it sufficient to pass SFI 4.1 certifications without the need for any external shields or internal liners. The 2-piece design allows them to be used with all popular engines by simply changing bolt-on bellhousings. Features include: * Speedometer and governor provisions * Longer band anchor pins captured by oversize bosses * Multiple external pressure taps allow for monitoring of circuit pressures * Accepts all style oil pumps, including 8-bolt and vari-pitch designs * Heli-coiled bellhousing and oil pump threads * Pre-machined to fit larger custom planetary gear carriers
