Late 50's very early 60's mopar automatics had a rear pump and could be push started, not since about 1963 for mopar. TimI'm not sure what vehicle it was Thunderhead, but it was an automatic I know for sure and it was in the late 70s when it happened. Turn the key on, but the transmission in to gear and started pushing it.....got it up to a pretty good speed, may 35, 40 or so and it started. That's all I know, couldn't tell you what kind of car or transmission, but it started and off he went. Wish I could be more help.
