I have an automatic transmission car with a SFI 29.1 flex plate, a
SFI 4.1 steel transmission shield, and an SFI 30.1 bell housing. The bell
housing is made for racing, but is a 1" thick aluminum unit with a SFI 30.1
sticker. It appears from reading rule 3.0 is that automatic
transmission cars do not require the 1/4" steel bell housing.
Bottom line, do auto trans cars with a flexplate and no clutch still require the 1/4" steel bell housing?
