Expert Insight: The Dealership Alternative
“We had a customer with a 2011 Sierra 2500 who was quoted over $700 by the dealership to diagnose and replace his TCCM. The quote included hours of diagnostic time and a hefty fee for programming the new module. He was hesitant, so he called us. We identified the part, confirmed the symptoms, and shipped him this exact pre-programmed module. He installed it himself in under 30 minutes in his driveway. The truck shifted perfectly, the light went out, and he saved hundreds of dollars. This isn’t just a part; it’s a smarter, more efficient repair process.”

Frequently Asked Questions
What is a TCCM and what does it do?
The Transfer Case Control Module (TCCM) is a small computer that acts as the ‘brain’ for your vehicle’s four-wheel-drive system. It receives input from the 4WD switch on your dash and sends commands to the transfer case motor to shift between 2WD, 4HI, and 4LO.
How do I provide my VIN for programming?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we receive your VIN, as the programming is essential for it to function correctly in your vehicle.
Is any additional programming needed after installation?
No. Because we pre-program the module to your specific VIN, it is a true plug-and-play installation. No further programming or dealership visits are required. In some cases, you may need to clear old fault codes with a standard OBD2 scanner after installation.
How can I be sure this fits my truck/SUV?
Please review the detailed fitment list in this description. This module is compatible with a wide range of 2007-2014 GM trucks and SUVs. Matching one of the compatible part numbers (e.g., 24239190, 24261367) also ensures a correct fit. Providing your VIN for programming is the final step to guarantee it works perfectly with your vehicle’s specific options.
Where is the TCCM located on my vehicle?
On most GM trucks and SUVs from this era, the TCCM is located on the driver’s side of the dashboard, up and to the left of the steering column. It’s typically a black box with several electrical connectors and can be accessed by removing the lower dash panel.
