Frequently Asked Questions
What is the main benefit of a VIN-programmed module?
VIN programming ensures the TCM works seamlessly with your specific vehicle’s engine, anti-lock brake system, and other electronics right out of the box. It eliminates the need for a separate, costly programming service at a dealership, making the installation a true plug-and-play process.
