Chrysler Corp. stopped producing the pushbutton automatics is 1964

The "1965" XM410E1 8x8 transport truck that I ran prototype evaluation tests on for the army, at Yuma Proving Grounds from 1965 - 1968 had the notorious "push button automatic" transmission. My memoirs show that we broke more than 40 sets of buttons in the process of demonstrating that the Chrysler proposal was "less than optimum" for adoption by the Army.

Although I did manage to break an axle off mine, my testing was less severe than the Marine Corps crew at San Diego, who sank theirs in ~60 feet of water in San Diego harbor, while swimming it around. The crew at Ft. Knox reportedly lost more than a couple of weeks when theirs was mired in the mud and eventually required an M88 to get it out.

Not exactly a happy experiment for Chrysler, although it was a real fun sportster for cruising around the desert.
