4L80e fitted. Having trouble locating a matching file that will swap with our OS.
OS 12592433. VZ Commodore 5.7 DBW.
Have tried 12592618 (05 Caddy) which I could use an 05 silverado file for seg swap but we lost functionality in the car (dash etc)
Read file as PCM came in.hpt05 Caddy.4l80e.1barSD.All original data copied over.hpt
