There are approximately 300-400 unique parts in an automatic transmission, and a transmission is generally the most complicated component of an auto. To design a transmission may take six months to a year, and even then it may take longer to actually get it built and functioning. However, a program with 500 to 600 functional parts would have 200 to 300 lines of actual code, and would probably take a good programmer a day to a week to write, test and debug.
