Hey P, That C&O stick hydro had its own "detents." It is like a normal automatic transmission that requires someone to pull the lever back to get it into reverse or park. The white ball or even a black ball does not have the weight to drop it accidentally into gear. This was not a home grown modified transmission, but a professionally built and installed, Stick Hydramatic transmission. It was the early competitor to the famous B&M stick hydro transmission. It was set up to go through individual gears or go full automatic. So, the shifting pattern was the same, but the shifts were either manually controlled and run through each gear, or simply drop it into 4 for a full automatic shifting transmission, that an older mom could easily drive. That previous example should be taken lightly...not a golden rule. The funny thing was, once modified, the C&O guys made the transmission shift like no other. It actually made people's heads move with each shift under full power. But, the look was strictly stock from the factory...without the selector window. Jnaki The old posts will tell, my mom was challenged many times by the local hot rodders in their modified cars. They revved up their motor and made the sign of ...lets race. My mom just looked forward and drove home. My comment to her was, just step on the gas to go across the intersection on the green light. Besides, when my mom says she cannot drive a 3 speed stick shift 58 Impala with a super heavy duty clutch, I had to listen to options. She said that she would pay to have the 58 Impala converted to automatic. Well, she did say automatic, so the C&O stick hydro was an automatic. It was just a little different style of automatic transmission. So, the conversion took place. A win/win in our book.
