Just installed gm ls3 engine controller kit 19354332with connect and cruse controller for 4l65 transmission 19302405 trans wont shift out of first gear. I have 1st and reverse with tcm connected good speed signal from vss have speed signal to digital dash as speedo will work. I believe i am missing controller info to ecm to command shift. I cant copy caliration from tcm to add file to engine controller. Does anyone have a tcm file for this combo?
