Is your Sierra, Silverado, or Camaro suffering from erratic shifting, a lit-up check engine light, or a dreaded “Service Transmission” message? These are classic signs of a failing Transmission Control Module (TCM), a critical component that can bring your powerful truck or performance car to a grinding halt. Don’t let a faulty module dictate your vehicle’s reliability and leave you stranded. This is the definitive, hassle-free solution to restore your transmission’s performance and get you back on the road with confidence.
Common Symptoms & Your Solution
A failing TCM can manifest in various frustrating ways. You might be experiencing harsh or delayed gear changes, the transmission getting stuck in one gear (limp mode), or even a complete no-start condition. Often, you’ll see diagnostic trouble codes (DTCs) like U0101 (Lost Communication With TCM) stored in the system. This pre-flashed module is the answer. We provide a fully programmed 24289415 TCM, updated with the latest software from GM and specifically calibrated to your vehicle’s unique Vehicle Identification Number (VIN).

An Expert’s Note: We recently helped a contractor whose 2021 Silverado 3500 dually was stuck in limp mode. He was losing money every day his truck was down and the dealership quoted him a four-day wait just for diagnostics. He ordered our programmed 24289415 TCM, we programmed it to his VIN and shipped it overnight. He installed it himself in under an hour the next morning and was back on the job site by noon. For professionals who rely on their trucks, minimizing downtime isn’t just a convenience—it’s essential for business.
Frequently Asked Questions
How do I provide my VIN for programming?
After you complete your purchase, you will receive instructions on how to send us your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is essential for the module to function in your vehicle.
Is any additional programming required after installation?
No. This module is completely plug-and-play. Because we use your VIN to flash it with the correct factory software, it will communicate with your vehicle’s other systems immediately upon installation. No trip to the dealer is necessary.
Will this fix a U0101 communication code?
Yes, a faulty TCM is the most common cause of a U0101 (Lost Communication With TCM) code. Replacing the failed module with this pre-programmed unit is the correct and most effective repair for that issue.
Where is the TCM located on my truck?
On most compatible Sierra and Silverado models, the TCM is located on the driver’s side (LH) core support, near the front of the engine bay. On the Camaro, it is typically found on the driver’s side (LH) frame rail, under the hood.
Is this a genuine GM part?
This is a high-quality replacement part that is programmed using official GM software and calibration files. It is designed to meet or exceed original equipment specifications for performance and reliability. By purchasing our programmed 24289415 TCM, you are getting a reliable, fully updated component.
