Frequently Asked Questions
Do I need to take this module to a dealer for programming?
Absolutely not. The main benefit of this part is that we program it to your vehicle’s specific VIN before we ship it to you. This makes it a true plug-and-play solution, saving you time and money.
How do I provide my VIN number?
After you complete your purchase, you will need to send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information for programming.
Is this part difficult to install?
For most of the listed GM trucks and SUVs, the TCCM is located on the driver’s side, up under the dashboard. It’s typically held in by a few bolts or clips and has a few electrical connectors. For someone with basic mechanical skills, it’s a very manageable job that can often be completed in under an hour.
How can I be sure my old TCCM is the problem?
Common symptoms include the ‘Service 4WD’ light, the selector switch lights being inoperative or flashing, and an inability to shift the transfer case between modes. A professional scan for TCCM-specific trouble codes (like C0327) is the best way to confirm the diagnosis.
Which part numbers does this module replace?
This module is a direct replacement for a wide range of original GM part numbers, including 24261367, 12588096, 24239190, 24240487, 24241143, 24241970, 24242480, 24243084, 24243085, 24249095, and 24252878.
