Expert Insight from the Garage: We constantly see these GMT900-platform trucks and SUVs come in with 4WD problems. Often, the owner has already replaced the selector switch, thinking it’s the culprit. In reality, the original TCCM is the weak link, prone to internal electronic faults.

The updated software we install directly addresses the root causes of failure, giving you a dependable 4WD system you can count on for years to come.
Frequently Asked Questions
How does the VIN programming work?
After you complete your purchase, you will need to provide us with your vehicle’s 17-digit VIN. Our technicians use this number to flash the module with the exact software and calibrations specified by GM for your truck’s specific options and configuration. This ensures perfect communication between the TCCM and your vehicle’s other computer systems.
Is this a true plug-and-play installation?
Yes. Because the module arrives pre-programmed, the physical installation is all that’s required. You simply disconnect the battery, locate and swap the old module with the new one, and reconnect the battery. No special tools or dealer software are needed. Some vehicles may require a ‘re-learn’ procedure which can be done without tools, but many will work immediately.
Will this fix my ‘Service 4WD’ light?
In the vast majority of cases where the TCCM is the diagnosed point of failure, this module will resolve the issue and turn off the warning light. We always recommend confirming the diagnosis or checking for related trouble codes before ordering to ensure you are addressing the correct problem.
What if my original part number is different from 24240487?
No problem. This module is a direct replacement for all the part numbers listed in the description, including 24261367, 12588096, 24239190, and more. As long as your vehicle is on the compatibility list, this part will work perfectly.
Where is the TCCM located on my truck?
On most compatible models like the Silverado, Sierra, and Yukon, the Transfer Case Control Module is located on the driver’s side of the dashboard, up and to the left of the brake pedal, mounted to the dash support frame. It is typically a black box with two or three electrical connectors.
