Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship your part until we receive this information, as the programming is a critical part of the process.
Is this part truly plug-and-play?
Yes. Because we program the module to your specific VIN before shipping, it arrives ready to be installed without any need for further dealer programming. In some rare cases, a ‘relearn’ procedure may be needed, but the core programming is complete.
Will this fix my ‘Service 4WD’ light?
In the vast majority of cases, yes. The ‘Service 4WD’ light is most commonly triggered by an internal failure of the TCCM. As long as the module is the root cause of the problem, this replacement part will resolve the issue and turn off the light.
How can I be sure my TCCM is the problem?
Common signs include the ‘Service 4WD’ light, inability to shift the transfer case, or diagnostic codes pointing to the TCCM (like C0327). While this part fixes the most common cause, it’s always best to have your vehicle properly diagnosed if you are unsure.
Where is the TCCM located on my truck?
On most of the listed GM trucks and SUVs, the Transfer Case Control Module is located on the driver’s side of the dashboard, up and to the left of the steering column. It is typically accessible after removing the lower dash panel.
Does this fit models other than the Sierra 2500?
Absolutely. This 2007-2014 Sierra 2500 Transfer Case Control Module is compatible with a wide array of GM vehicles, including the Silverado 1500/2500/3500, Suburban, Tahoe, and Yukon. Please check the detailed fitment list in the description to confirm compatibility with your specific year and model.
