Get Your Truck Back on the Job, Fast.
Is your GMC Sierra or Chevrolet Silverado suffering from harsh shifting, getting stuck in gear, or an illuminated check engine light? A failing Transmission Control Module (TCM) can sideline your truck, costing you time and money. This direct-fit 2015-2016 Sierra 2500 TCM 24276411 is the definitive solution to restore your transmission’s performance and reliability. We take the guesswork out of the repair by pre-programming the module to your truck’s specific Vehicle Identification Number (VIN) before it ships. This means no expensive trips to the dealership for programming—it’s ready for installation right out of the box.
Common Symptoms & Your Solution
A faulty TCM can manifest in several ways, often triggering diagnostic trouble codes (DTCs) like P0700 (Transmission Control System Malfunction) or U0101 (Lost Communication with TCM). If you’re experiencing any of the following, this module is the component you need:
- Erratic or delayed shifting
- Harsh engagement into drive or reverse
- Vehicle entering “limp mode” with reduced power
- False neutral or getting stuck in one gear
- “Service Transmission” warning on your dashboard
By replacing your old module with this professionally programmed unit, you’re not just fixing a part; you’re restoring the precise, factory-intended operation of your Allison or 8-speed transmission.

Expert Insight: The Critical Role of VIN Programming
From over 20 years of hands-on diagnostics, I can tell you that improper programming is the #1 reason for a failed TCM replacement. Generic, non-programmed modules simply can’t communicate correctly with your vehicle’s other computers, like the Engine Control Module (ECM) and Body Control Module (BCM). This leads to immediate shifting problems and error codes. By programming this 2015-2016 Sierra 2500 TCM 24276411 to your exact VIN, we ensure all vehicle-specific parameters—like tire size, axle ratio, and option packages—are correctly loaded. This isn’t just a convenience; it’s the only way to guarantee a successful and lasting repair.
Frequently Asked Questions
Is this part truly plug-and-play?
Yes. Because we program the module to your specific VIN before shipping, it is ready for installation upon arrival. In most cases, no further programming or relearn procedures are required. Simply install the module and your vehicle is ready to go.
How do I provide my VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). You can typically find this on your driver’s side door jamb sticker, your vehicle’s registration, or on the dashboard viewable through the windshield.
Will this fix my truck’s limp mode issue?
If the limp mode is being caused by a faulty TCM, then yes, this part is designed to resolve that issue. A diagnostic scan to confirm TCM-related trouble codes is always the best first step.
What happens if I forget to send my VIN?
We cannot ship your order until we receive your VIN, as the programming is a critical step in the process. We will reach out to you, but providing the VIN at the time of purchase will ensure the fastest possible processing and shipping.
Does this fit vehicles other than the Sierra 2500?
Absolutely. This module fits a wide range of 2015-2017 GM vehicles, including the Silverado 1500/2500/3500, Escalade, Yukon, Camaro, and CTS. Please check the detailed fitment list on this page to confirm compatibility with your specific model and options.
