    Default looking for stock lb7 zf6 file

    I am in the process of making a truck work that the owner converted to a zf6 manual transmission. It is a 2003 lb7, 2500, crew, shortbox, 4wd, LT all options except sunroof. Can someone provide me with a stock file?

    Do you know what OS and segments you need?

    Id like to look at a complete file so I can compare to what we have and build a good driving cal for a manual transmission truck. The lb7 in question has mannerisms similar to my factory zf6 lly when it had factory tuning. No power under 1700 rpm and then a rapid, almost hard to control torque rise between 1700-1900 depending on conditions.

    Why does the file show the transmission as automatic? Were trying to get the pcm not to search for a tcm.
