An Expert’s Note on Programming
As a technician, I’ve seen countless vehicle owners try to save a few dollars with a used TCCM from a salvage yard, only to create more problems. These modules are not one-size-fits-all. They are tied to the specific options (RPO codes) of the vehicle they came from. Installing an incorrectly programmed module can lead to persistent error codes, erratic 4WD behavior, or a complete failure to communicate. Our VIN-programming service ensures this Programmed Transfer Case Control Module 24242480 is an exact electronic match for your truck, guaranteeing a successful repair the first time.

How do I provide my VIN number?
After you complete your purchase, you can add your VIN to the ‘notes’ section of your order. If you forget, we will contact you via email to request it before we ship your part. We cannot ship the module without programming it first.
Will this fix my “Service 4WD” light for sure?
A faulty TCCM is the most common cause for this warning light and the associated symptoms on these GM vehicles.

On most compatible GM trucks and SUVs, the TCCM is located on the driver’s side, up under the dashboard to the left of the steering column. It’s typically held in place by a few small bolts or clips, making it accessible for a DIY replacement.
What if my original part number is not on the compatibility list?
The provided list covers the most common compatible part numbers. However, if your number is different, please contact us with your vehicle’s VIN. We can verify if this module is the correct, updated replacement for your specific application.
