Expert Insight: The Cost of Downtime
We once had a contractor call us, stuck at a muddy job site. His Silverado’s 4WD wouldn’t engage, and his crew was at a standstill. The dealer quoted him a two-day wait just for diagnostics. We programmed a 2007-2013 Sierra 1500 transfer case control module to his VIN and overnighted it. He installed it in his truck’s cab in under 30 minutes the next morning and drove right out of the mud. For him, this wasn’t just about fixing a light on the dash; it was about preventing lost income and keeping his business moving. That’s the real-world value of a reliable, ready-to-install part.
Frequently Asked Questions
Do I need to get this module programmed by a dealer?
Absolutely not. We handle all the programming for you before the part is shipped. Simply provide us with your vehicle’s VIN during checkout, and the module will arrive ready for a plug-and-play installation.
How do I find and provide my VIN?
Your 17-digit Vehicle Identification Number (VIN) can be found on your vehicle’s registration, insurance card, or on the driver’s side dashboard viewable through the windshield. Please provide this number to us after you complete your purchase so we can program your specific module.
What if this doesn’t fix my 4WD problem?
While this TCCM is the most common solution for 4WD electronic issues, other components like the transfer case encoder motor or the dash switch can also fail. We recommend proper diagnostics to confirm the TCCM is the faulty part. However, if you receive a defective module, it is covered by our warranty.
Is this compatible with my 2007 ‘classic’ body style truck?
This module is for the ‘new style’ (NBS) GM trucks starting in 2007, which are identifiable by a smooth door skin. It is not compatible with the 2007 ‘classic’ (OBS) body style. Please verify your vehicle style before ordering.
Will this work for my Yukon Denali?
Yes, this module is compatible with a wide range of GM models, including the Yukon Denali, Sierra Denali, Suburban, and Tahoe within the specified year ranges. Please refer to the detailed fitment list on this page to confirm your exact model and year.
