Are you referring to the Hydra-Matic plant fire in 1953? (if you are referring to another fire, I'll delete this post - sorry).

If you are referring to the H-M Plant fire: "By the time the 1954 models debuted in late 1953, Hydramatic production had returned to normal levels and all '54 model Cadillacs, Oldsmobiles and Pontiacs with automatic transmissions were once again equipped with Hydramatics."
