Expert Insight: The ‘Plug-and-Play’ Difference
As a technician, I’ve seen countless truck owners buy a blank control module online, only to find out it’s a useless box until it’s programmed by a dealer with a special scan tool. That dealer visit can cost anywhere from $150 to $300 and means your truck is out of commission. Our process eliminates that completely. We do the complex programming work for you before it ever ships. When you get this 2007-2014 GM Transfer Case Control Module, you can install it in your own driveway in under an hour with basic tools. You’re not just buying a part; you’re buying a complete, cost-effective solution that gets the job done right.
Frequently Asked Questions
Do I need to do any programming or take this to a dealer?
Absolutely not. This is the main benefit of our service. We program the module to the VIN you provide, so it arrives ready for installation. Simply disconnect the old module and plug this one in. No dealer visit or special tools are required.
Where is the TCCM located on my vehicle?
On most compatible models like the Yukon, Tahoe, Sierra, and Silverado, the Transfer Case Control Module is located on the driver’s side, up under the dashboard to the left of the steering column. It’s typically a black box with a few electrical connectors.
How do I give you my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive the VIN, as the programming is specific to your vehicle.
My old module has a different part number. Will this still work?
Yes. GM uses many different part numbers for the same component over the years. Our module is compatible with all the part numbers listed in the description, including 24261367, 12588096, 24243085, and more. As long as your vehicle is on the fitment list, this programmed module is the correct part for you.
Will this fix other 4WD problems?
This 2007-2014 GM Transfer Case Control Module is the solution for electronic control issues. It will not fix mechanical problems within the transfer case itself (like a stretched chain or bad gears) or a faulty encoder motor. However, the TCCM is one of the most common failure points in the GM 4WD system for this generation of trucks and SUVs.
