TRANSMISSION IDENTIFICATION

The transmission identification code will differ depending the type of transmission - Manual or Powerglide.

  • The Muncie and Powerglide will have a production code consisting of a prefix letter designating the assembly plant, a production date (month/day number) and a shift code for day or night shift if the transmission assembly plant was using two shifts.
