When did P-A go to synchromesh trans? Was it fully synchro or just 2nd & 3rd?
1932. I believe that synchro was 2nd and 3rd.
However, in late 1931-early 1932, PAMCC offered a factory-subsidized transmission replacement for 1929-31 automobiles, including the 1932 synchro. I know of one 1932 trans installed years ago in a 1930 Model B. The full details (as I recall, the text of the offer) are in a Service Bulletin issued within the last 20 years 🙂 but I can’t tell you which one. One could also get the 1930-only Clark 4-speed or the 1931-only freewheeling unit with the button in the knob.
