I never saw anyone who had trouble with push button automatics. I heard rumors, but never actually knew anyone who had problems. This is from the day they were new, to where you could buy the car for $50 if it ran good, and the floor was still good enough that the seat didn't rock, to the collector cars they now are. I had 57 and 58 Mercurys, 58 Edsil, 56-64 Chrysler products with them, NEVER HAD PROBLEMS. With the Mercury and Edsils, that was about the only parts that were trouble free. Chrysler didn't stop using them because of problems, they stopped because the US Government mandated a standard automatic transmission selector starting 1955. GM had to redesign their transmissions to put the R between P and N, instead of all the way to the bottom where it had been from day one.JOhn
