Restore Your Sierra’s Uncompromising Performance
A truck like the GMC Sierra Denali 3500 isn’t just a vehicle; it’s a critical tool for your business, your family, and your lifestyle. When transmission issues arise, everything stops. Hard shifting, delayed engagement, or a check engine light can sideline your powerful truck, costing you time, money, and confidence. This pre-programmed Transmission Control Module (TCM) is the definitive solution to get your truck back on the road, performing with the power and smoothness you expect from a Denali.
Common Symptoms & Your Solution
If you’re experiencing issues like harsh 1-2 shifts, erratic gear changes, or getting stuck in one gear, a failing TCM is the likely culprit. You may also see a “Service Transmission” message on your dash or have trouble codes such as P0700 or U0101 stored in the system. This module is engineered to resolve those exact problems. We eliminate the guesswork and the expensive trip to the dealership by programming this 2020-2022 Sierra Denali 3500 TCM 24296206 specifically to your truck’s Vehicle Identification Number (VIN) before it ever leaves our facility.

A Veteran Technician’s Insight: In today’s complex trucks, the TCM is more than just a transmission controller; it’s a central node in a network. We see it all the time: a customer buys a module online, installs it, and the truck won’t even start. That’s because it hasn’t been programmed to communicate with the Engine Control Module, the Body Control Module, and even the anti-lock brake system. Our VIN-programming service isn’t a convenience, it’s a necessity. We ensure that when you plug in our 2020-2022 Sierra Denali 3500 TCM 24296206, it speaks the exact digital language of your specific truck, saving you from a world of frustration and a tow to the dealer.
