I believe that you're correct. See attached spec sheet from 1971 Pontiac sales brochure. This chart was taken from the GTO page, but I checked all of the other vehicles including Full-size, Grand Prix, Firebird and LeMans and they all showed that the only trans available for the 325 HP 455 was the Turbo Hydra-matic.
