Restore Your GM Truck’s Peak Shifting Performance
Experiencing harsh shifting, delayed engagement, or an illuminated Check Engine Light in your Sierra, Silverado, or Camaro? A failing Transmission Control Module (TCM) is often the culprit, disrupting communication and causing frustrating, unpredictable performance. This genuine GM TCM, service part number 24296206, is the definitive solution to get your vehicle back to operating with the smooth, decisive shifting you expect. We take the guesswork and dealer hassle out of the equation by pre-programming the module to your vehicle’s specific VIN before it ships, ensuring a seamless installation process.
Common Symptoms & Your Solution
If your vehicle is exhibiting any of the following issues, a faulty TCM is the likely cause. This module is designed to permanently resolve these problems:
- Erratic or harsh shifting between gears
- Vehicle stuck in one gear (limp mode)
- Delayed engagement when shifting into Drive or Reverse
- Check Engine Light with transmission-related Diagnostic Trouble Codes (DTCs) such as P0700, P0751, or U0101

Frequently Asked Questions
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your order until we receive and validate your VIN, as this information is essential for programming the module correctly.
Is any additional programming required after installation?
No. This Programmed 24296206 TCM arrives ready to install. Because it’s flashed to your specific VIN, it will communicate with your vehicle’s other modules correctly. In some cases, a transmission fluid pressure or clutch adaptive learn procedure may be recommended with a capable scan tool to ensure the absolute smoothest shifting, but the core programming is complete.
Where is the TCM located on my truck?
On most compatible Sierra and Silverado models from 2019 onwards, the TCM is located on the driver’s side (LH) core support in the engine bay. On the Camaro, it’s typically found under the hood on the driver’s side (LH) frame rail. Always consult a service manual for your specific vehicle to confirm the location before beginning work.
Will this fix my specific transmission problem?
This module is a direct solution for issues caused by a failed TCM, including many common electronic and communication-related fault codes. While it resolves the most frequent problems, it’s always best to have a proper diagnosis performed to rule out mechanical issues within the transmission itself. This part will not fix problems related to worn clutches, a bad valve body, or torque converter failure.
How can I be sure this part is compatible?
This module is a direct replacement for several service numbers, including 24296206 and 24289415. The best way to ensure compatibility is to match the part number from your old unit and provide us with your VIN. Our programming process cross-references your VIN with the GM database to ensure you receive the correctly configured part for your truck’s specific options.
