Expert Insight: Why VIN Programming is Non-Negotiable
Many people are tempted to grab a used TCM from a salvage yard, thinking it’s a cheap fix. What they don’t realize is that a TCM is not a one-size-fits-all part. It’s programmed to its original vehicle’s specific configuration—engine size, gear ratios, tire size, and even trim-level options. Installing an un-matched module will, at best, cause poor performance and, at worst, can prevent the vehicle from starting or even damage the transmission. Our process of programming the module to your VIN ensures that the component communicates flawlessly with your vehicle’s entire network, just as the original did. This is the difference between a temporary patch and a lasting, reliable repair.
Don’t let a faulty module dictate how your vehicle drives. Take control of the repair with this fully prepared Programmed 2005 Grand Prix TCM and get back to driving with confidence and security.

Is any additional programming needed after I install it?
