Restore Crisp, Decisive Shifting to Your GM Vehicle
Is your 2016 Camaro, Sierra, or Silverado suffering from erratic shifting, a check engine light, or getting stuck in gear? These are classic symptoms of a failing Transmission Control Module (TCM). As the electronic brain of your automatic transmission, a faulty TCM can cripple your vehicle’s performance and leave you stranded. In my 20+ years of experience, I’ve seen how a malfunctioning TCM can cause a cascade of frustrating issues, often misdiagnosed as internal transmission failure. This replacement TCM, part number 24272004, is the definitive solution to get your vehicle operating smoothly and reliably again.
The biggest hurdle in replacing a modern module is the expensive and time-consuming programming required at a dealership. We eliminate that step entirely. By providing your Vehicle Identification Number (VIN) at checkout, you receive a module that is professionally flashed with the latest GM-certified software specific to your vehicle. This isn’t just a replacement; it’s a fully prepared component, ready for installation right out of the box. This process ensures perfect communication between the new 2016 Camaro TCM and your vehicle’s other systems, restoring factory-spec shift points and performance.
A Technician’s Notebook: The Silverado That Wouldn’t Shift
A customer brought in a 2015 Silverado 1500 with the 8-speed transmission. The complaint was harsh 1-2 shifts and occasionally getting stuck in what felt like 3rd gear (limp mode). The dash was lit up with a check engine light and a “Service Transmission” message. A quick scan pulled code U0101 – Lost Communication with TCM. While this can sometimes be a wiring issue, I’ve seen enough of these to be suspicious of the module itself. After verifying power and ground at the TCM connector were solid, we knew the module was the culprit. Instead of towing it to a dealer for a new module and programming, we ordered a VIN-programmed unit like this one. The part arrived, we installed it in under an hour, and the truck was shifting perfectly on the test drive. The customer saved hundreds in dealer fees and got their truck back a day earlier. It’s a prime example of how a pre-programmed module is the smartest repair.
Common Signs of a Failing GM TCM
- ✔ Check Engine Light is on with transmission-related Diagnostic Trouble Codes (DTCs) such as P0700, P0751, or U0101.
- ✔ Harsh, delayed, or erratic shifting between gears.
- ✔ Vehicle gets stuck in one gear (often called “limp mode”).
- ✔ The transmission seems to slip or fails to engage properly from a stop.
- ✔ Inaccurate gear indicator on the dashboard.
- ✔ A noticeable decrease in fuel economy due to inefficient shifting.
A Straightforward Guide to Installation
- ✔ Safety First: Disconnect the negative terminal from your vehicle’s battery and wait a few minutes to ensure all systems are powered down.
- ✔ Locate the TCM: On the 2016 Camaro, the TCM is located on the driver’s side (LH) frame rail, under the hood. On trucks and SUVs like the Sierra or Escalade, it’s typically mounted to the LH core support or radiator fan shroud.
- ✔ Disconnect Wiring: Carefully release the locking tabs on the electrical connectors and pull them straight out from the module. Do not force them. Inspect connectors for any corrosion or damage.
- ✔ Remove the Old Module: Unbolt the old TCM from its mounting bracket. There are typically two or three bolts holding it in place.
- ✔ Install the New Module: Mount your new, pre-programmed TCM onto the bracket and secure it with the original bolts.
- ✔ Reconnect and Secure: Firmly plug the electrical connectors back into the new module until they click into place. Reconnect the negative battery terminal.
- ✔ Final Check: Start the vehicle and check for any warning lights. Take a short test drive to confirm that shifting is smooth and responsive. No further programming is required.

Frequently Asked Questions
Do I need to do any programming after I install this TCM?
No. This module arrives fully programmed to your vehicle’s VIN with the latest GM software. It is a true plug-and-play solution. Just install it and you’re ready to go.
What information do you need from me?
After you complete your purchase, you will need to provide us with your 17-digit Vehicle Identification Number (VIN). This is essential for us to program the module correctly for your specific vehicle.
Is this compatible with part number 24276411?
Yes, this module is a direct replacement and is fully compatible with vehicles that originally came with part number 24276411.
Will this fix a U0101 communication code?
In many cases, yes. A U0101 code indicates a loss of communication with the TCM. If the wiring and power/ground sources to the module are confirmed to be good, a failed internal circuit in the TCM is the most common cause, and replacing it will resolve the code.
How difficult is the installation?
For someone with basic mechanical skills and tools, this is a straightforward job that can typically be completed in under an hour. The module is usually in an accessible location under the hood.
