We are converting an 11 to a 4l80, just wondering what can be done to tell the PCM it is a man trans (to keep the bus from getting confused looking for a tcm and neutral safety etc)
Do I write a new man trans file and enable the VVT or stick with stock file and modify it somehow??? I am not finding ANY trans reference items in the PCM therefore I believe I will try the man trans cal idea...
thanks
