Transmission, Automatic:
Non-OEM transmissions are prohibited. Aftermarket torque converters, valve bodies and internal components are
permitted. Transmission brakes are prohibited. Any non-OEM floor-mounted automatic transmission shifter must be
equipped with a spring-loaded positive reverse lockout device to prevent the shifter from accidentally being put into
reverse gear. A functional neutral safety switch is mandatory. All transmission lines must be metallic or high-pressuretype
hose. All vehicles with engines running 4500 RPM or more and using an automatic transmission must be equipped
with a transmission shield meeting SFI Spec 4. 1 and must be labeled accordingly. A blanket-type shield, appropriately
labeled as meeting SFI Spec 4. 1 and extending from the rear of the block to front of tailhousing with a minimum six inch
overlap where it is fastened, is permitted. All non-blanket-type shields must incorporate two (or one, per manufacturer’s
instructions) ¾ inch by ⅛ inch straps that bolt to the shield on each side and pass under the transmission pan unless the
transmission pan is labeled as meeting SFI Spec 4. 1. All vehicles with engines running 4500 RPM or more and using an
automatic transmission must be equipped with a flex plate meeting SFI Spec 29. 1 and be covered by a flex plate shield
