having problems getting the trans to shift right also not getting a VSS signal to the PCM. As far as we can tell from the pinouts everything seems to be wired right but the trans temp is stuck at 32*F, no VSS signal, no reverse switch signal, and the speedo is stuck on 158 mph. All of those things seems to be controlled on the CAN BUS correct? Is their anyway to test those sensors to make sure we are getting a signal out of the trans? The PCM and TCM came out of the same CTSv that the motor and trans came from but the BCM is from a 08 Acadia that also had the 6l80e trans in it.

Wow, very cool project. What did you do for a wiring harness for this? I like your ambition, and would like to add in a newer BCM, so I could add in some newer features. Would love to see some pics of this!
