For information purposes, the Chrysler push-button shifters worked very similar to the pushbuttons on the old radios; each button moved a rocker to a preset position, which moved a cable that went to the transmission. The cable was attached to a hydraulic valve inside the tranny which selected the direction of oil flow. The oil pressure activated the proper clutch or servo to put the transmission into the desired gear.
Since AMC used Chrysler automatic transmissions, their system was the same.
I do not know about Edsel, never had to work on one
AMC did not use Chrysler automatic transmissions until the early 1970's. Prior to that, they were Borg-Warner.
