" Hydra-Matic didn’t have a Park position until the second-generation Controlled Coupling Hydra-Matic arrived in 1956, but with the engine off, the reverse pawl would effectively lock the transmission output shaft, serving the same purpose."
Not sure why they did it that way, but people who drove manual transmissions were used to leaving them in gear when they parked.
