Expert Insight: Why VIN Programming is Crucial
Many sellers offer generic or non-programmed modules, but this is a critical mistake. Your vehicle’s transmission behavior is fine-tuned at the factory based on its engine, axle ratio, and tire size. A Programmed T42 Transmission Control Module with your exact VIN ensures all these parameters are correct. Installing a generic unit can lead to continued shifting problems, incorrect speedometer readings, and even long-term transmission damage. Our process guarantees that the module you receive is a perfect software match for your vehicle, just as the manufacturer intended.
