Restore Your 4WD System with Confidence
Is the ‘Service 4WD’ light on your dash causing you stress? Are you unable to switch between 2WD and 4WD, or hearing unusual noises from your transfer case? A faulty Transfer Case Control Module (TCCM) is often the culprit, leaving your capable truck or SUV stuck with two-wheel drive. This isn’t just an inconvenience; it’s a reliability issue. Get back the all-weather, all-terrain capability you depend on with this direct-fit, professionally programmed TCCM.

Expert Insight: Why Pre-Programming is Non-Negotiable
As a veteran technician, I’ve seen countless people try to save a few dollars by installing a used TCCM from a salvage yard. It almost never works. These modules are not one-size-fits-all; they are coded to the original vehicle’s specific options (RPO codes), like axle ratios and transfer case type (e.g., NQH, NQF). Installing an un-programmed or incorrectly programmed module will result in communication errors and a non-functional 4WD system. Our service eliminates this critical point of failure, providing a Programmed GM Transfer Case Control Module that is guaranteed to communicate correctly with your vehicle right out of the box.
Frequently Asked Questions
How does the VIN programming process 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 access the official GM database and flash the module with the exact software and calibrations your specific vehicle requires. This makes the installation seamless.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is very straightforward. The TCCM is typically located under the driver’s side of the dashboard. It involves disconnecting the battery, removing a few trim panels, and swapping the electrical connectors from the old module to the new one. No special tools are required.
My original part number is different. Will this still work?
Yes. This module, 24261367, is the updated replacement for a long list of previous part numbers, including 24252878, 24249095, 12588096, and many others listed in the description. As long as your vehicle is on the compatibility list, this programmed module is the correct part for you.
What happens if I don’t provide my VIN?
Providing your VIN is a required step for this purchase. We cannot ship the module without programming it first, as an un-programmed module will not function in your vehicle. This critical step ensures you receive a fully functional, plug-and-play part.
Do I need to send my old module back?
No core charge or return is required for this part. You can simply keep or dispose of your old module after installing the new one.
