Restore Flawless Shifting to Your GM Vehicle
Is your Camaro, Sierra, or Escalade suffering from erratic shifting, delayed engagement, or throwing transmission-related error codes? A failing Transmission Control Module (TCM) is often the culprit behind these frustrating and potentially damaging issues. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating precise gear changes, managing fluid pressure, and ensuring a smooth driving experience. When it falters, you’ll notice it immediately. This unit, part number 24276411, is a direct-fit, reliable solution, pre-programmed with the latest GM software specifically for your vehicle’s VIN.
Signs Your Transmission Control Module is Failing
A faulty TCM can manifest in various ways, from subtle annoyances to critical failures. If you’re experiencing any of the following, it’s time to inspect your module. Ignoring these symptoms can lead to more significant transmission damage down the road.
- ✔ Harsh or erratic gear shifts
- ✔ Getting stuck in a single gear (limp mode)
- ✔ Delayed engagement when shifting from Park to Drive or Reverse
- ✔ Check Engine Light or Transmission Warning Light illumination
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0751, or U0101 (Lost Communication with TCM)
- ✔ Inaccurate gear indicator on the dashboard
Simple Installation Guide for Your 2016 Camaro TCM
Replacing the TCM is a straightforward job for a seasoned DIYer or any professional technician. Our VIN-programming service eliminates the need for expensive dealership tools, making this a plug-and-play repair.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On the 2016 Camaro, the TCM is typically found under the hood, mounted on the driver’s side (LH) frame rail. For trucks like the Sierra or SUVs like the Escalade, it’s often on the LH core support or fan shroud.
- Disconnect and Remove: Carefully unplug the main electrical connectors. Press the release tabs firmly and pull straight out. Then, unbolt the module from its mounting bracket.
- Install the New TCM: Mount the new module in the same location, securing it with the original bolts. Reconnect the electrical harnesses, ensuring they click securely into place.
- Reconnect Power: Reattach the negative battery terminal.
- Final Steps: Start the vehicle and let it idle for a few minutes. In some cases, a transmission adaptive pressure relearn procedure may be beneficial, which can be done with many professional-grade scan tools, but the vehicle will often relearn on its own over the first 50-100 miles of mixed driving.
From the Diagnostic Bay: The Ghost in the Transmission
A 2016 Sierra 1500 with the 8-speed M5U transmission came into the shop with a complaint of violently harsh 1-2 shifts and occasionally getting stuck in 5th gear. The owner had already replaced the valve body with no change. We scanned it and found intermittent communication loss codes with the TCM. Instead of just throwing another part at it, we checked the wiring harness—it was perfect. The issue was internal to the original TCM; heat cycles had caused a hairline fracture on the circuit board. Installing a properly VIN-programmed module like this one solved the problem instantly. The truck shifted like it just rolled off the assembly line. It’s a powerful reminder that correct diagnostics and a quality, correctly programmed part are key.

Frequently Asked Questions
Why do you need my VIN number?
Your Vehicle Identification Number (VIN) allows us to load the exact, factory-correct software for your vehicle’s specific configuration, including engine, transmission type, and any other options. This ensures the 2016 Camaro TCM communicates perfectly with other modules and controls the transmission as intended by the manufacturer.
Is any additional programming required after installation?
No. Our service ensures the module arrives fully programmed and ready for installation. In most cases, you will not need to visit a dealer or use a special scan tool. The vehicle will perform an adaptive learn process on its own during the first several drive cycles.
Will this fix a “No Communication” issue with my old TCM?
Yes, a complete loss of communication (often indicated by a U-code like U0101) is a very common failure mode for these modules. Replacing your faulty unit with this pre-programmed module is the correct and reliable fix for that specific problem.
Is this a new or used part?
This is a high-quality, inspected, and tested used OEM component. Each module is verified to be fully functional before it is programmed and shipped, providing OEM performance and reliability without the new-part price tag.
What is the warranty on this module?
All our electronic modules come with a standard warranty that covers defects in the part itself. Please refer to our website’s warranty section for specific details and duration for this part.
