Expert Insight: The Power of Proper Programming
From our 20 years of experience, we know that the single biggest point of failure for a TCM replacement is improper or non-existent programming. A generic, unprogrammed module simply can’t communicate correctly with your vehicle’s specific powertrain and security systems. That’s why we take the extra step to program each Buick Rendezvous Transmission Control Module 24256960 to your exact VIN before it ships. This ensures that once you install it—a job that typically takes less than 30 minutes—it works perfectly right out of the box, saving you from frustrating error codes and costly dealership visits.
