    stock ecm flash to manual trans

    Hi guys
    i'm new here thinking on using HPT on my 05 5.9 Cummins, i am swapping it into a super duty and needs to be a manual trans flash. the truck i stripped is an auto just curious is it is possible by reading and then writing over top or changing the auto file or a recovery file that is for a manual

    Don?t believe so with HP Tuners. MM3 yes.

    You can manipulate parameters to make things work properly with a manual transmission with HP Tuners but not change the entire operating system from auto to manual.
