You know about the PRNDL, of course:
That de-roundeled Bimmer probably doesn’t have a true PRNDL, but I never actually saw one until the middle 1970s, since we had owned only manual-transmission cars until I reached my teen years, and the first automatic I ever saw was this weird American Motors gadget:
What we had was a 1962 Rambler, and this was the shift mechanism, such as it was, for the three-speed automatic. At the time, I somehow failed to comprehend that “D1” was the normal driving mode, and that “D2” started you off in second. The Park function, apparently an afterthought, was controlled by a lever down below, east of the emergency-brake release.
After an indifferent experience with AMC, the family switched to Volkswagen Type 2s Microbuses with about twice the interior space and maybe one-quarter the horsepower. (It was in the second of those VeeDubs, a ’69 T2a, that I got my first chance behind the wheel. It was, of course, a four-speed manual, and in the absence of a tach, I learned how to maximize power from the little boxer four: shift when you’re afraid not to.)
My first actual PRNDL, then, was in the ’66 Chevrolet, acquired in 1975. A two-speed, yet.
