Hoping to get some help this possibly? I have gm sps2 but can’t get this 6L80 reprogram. Just to back track I was writing the controller with hptuners when the usb got bumped and it error’s. So now hptuners won’t recognize tcm to write calibration again? Controller access timed out everytime I try it so figured I’d use sps2 to program it but can’t get that to either. Error unrecognized or something like that. Reprogram replace or none of the programing options in sps2 will work. Is the tcm controller completely bricked or something? I’m going off memory here I didn’t think to get any pics earlier when I was trying it. Sps2 would get to fast relearn step after it would download calibration but fast relearn won’t happen cause no temp is registering from tcm. Also I don’t think fast relearn would be proper next step. Should go to the bulletins and calibration updates first on other modules I’ve done in the past. Any suggestions be great. Thanks

Sorry I bought a new or reman tcm and programmed it good to go now. I should have updated post.
