    T43 OS swap

    Hello,

    Can I swap any year T43 OS into any T43? I have a 2015 5.3 and a 2010 6L80, Can they work together?

    Thanks

    If this is not possible, can i uput a 2015 TCM in the 2010 6l80?

    generally anything later then 2010 will be compatible. the pre 09 ecu/tcm used a different canbus "protocol".

    I have a 2006 C6 with T43 OS 24237276. I checked tis2web and there is newer calibration available than I currently have in my car. I have tune file from other car with newer calibration. Can I just do write entire to TCM to get newer calibration?
