Expert Insight: The Critical Role of VIN Programming
Many TCCM failures today are software-related. Simply swapping in a used module from another truck, even an identical one, is a recipe for frustration. It will likely not work because it’s programmed for a different set of vehicle options (axle ratios, tire sizes, etc.). Our process of programming this module to your specific VIN before shipping is the crucial step that separates a successful repair from a wasted weekend. We aren’t just selling a part; we’re delivering a complete solution that communicates correctly with your truck’s Powertrain Control Module (PCM) and Body Control Module (BCM) from the moment you plug it in.
