All the 1962 to 1965 TorqueFlites are operated using cables. (1966 went to levers.)

I think this is the top-level view: "1962-1964 pushbutton 727 TorqueFlites are the same. The 1965 727 TorqueFlite can be used with pushbutton with a minor valve body/cable modification. The main difference you have to check is the bell housing bolt pattern...." 

You question seems "can I put the transmission in gear with the parking pawl engaged?" and the answer is no with the sliding park levers on 62-64s. I don't recall how the 1965 column shift lever accomplished that safety feature. Hopefully someone here knows.
