Restore Flawless Shifting and Reclaim Your Drive
Is your Cadillac, Sierra, or Silverado suffering from frustrating and unpredictable transmission behavior? As a technician with over two decades of experience, I’ve seen firsthand how a failing Transmission Control Module (TCM) can turn a great vehicle into a source of daily stress. Hard shifts, delayed engagement, or a transmission that seems to have a mind of its own are classic signs. You don’t have to put up with it or face an expensive bill from the dealership. This is the definitive, reliable solution you’ve been searching for.
This is a genuine GM Transmission Control Module, part number 24272004, that arrives at your door completely programmed and ready for installation. We take your vehicle’s specific VIN and flash the module with the very latest factory software from General Motors. This critical step ensures perfect communication between your engine and transmission, restoring the smooth, precise performance you expect. By choosing this pre-programmed 2016 CTS TCM, you are bypassing the most complicated and costly part of the repair process—no need for special scan tools or a trip to the dealer for programming.
Case Study: A Tricky Diagnosis
A customer brought in his 2016 Silverado 1500 with the 8-speed transmission. The complaint was intermittent, harsh 1-2 shifts and occasional slipping when cold. No check engine light was on, but a scan revealed stored history codes U0101 (Lost Communication With TCM) and P0700 (Transmission Control System Malfunction). We checked the fluid, wiring, and connectors—all perfect. The intermittent nature pointed directly to the TCM’s internal processor failing under certain temperature conditions. We installed one of our pre-programmed modules, performed a quick transmission service, and the truck was shifting better than new. The customer saved hundreds by avoiding dealership programming fees and got a permanent fix.
Is Your Vehicle Showing These Symptoms?
A faulty TCM can manifest in several ways. If you’re experiencing any of the following, this module is the likely solution for your vehicle.
- ✔ Check Engine Light is on with transmission-related codes (e.g., P0700, P0751, U0101).
- ✔ Harsh, slamming, or jarring shifts between gears.
- ✔ The transmission feels like it’s slipping or failing to engage properly.
- ✔ The vehicle gets stuck in one gear (often called “limp mode”).
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ “Service Transmission” or similar warning message on your dashboard.
A Straightforward Guide to Installation
Installing your new 2016 CTS TCM is a manageable job for a confident DIYer or a quick task for any professional mechanic. The exact location varies slightly by model (see fitment list), but the general process is the same.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electrical work.
- Locate the TCM: On most listed vehicles, the TCM is mounted on the driver’s side of the vehicle, often on the frame rail, core support, or near the radiator/fan shroud.
- Disconnect Electrical Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the connectors for any signs of corrosion or damage.
- Remove the Old Module: Unbolt the old TCM from its mounting bracket. There are typically a few small bolts holding it in place.
- Install the New Module: Mount your new, pre-programmed TCM onto the bracket and secure the bolts.
- Reconnect Everything: Firmly plug the wiring harnesses back into the new module until they click. Reconnect your vehicle’s battery.
- Final Steps: While the module is pre-programmed, some vehicles may require a simple transmission fluid level check or a quick drive cycle for the adaptive learning to fully sync. Your vehicle is now ready to drive.

Frequently Asked Questions
Do I need to do any additional programming after installation?
No. We flash the module with the latest GM software using your VIN before it ships. This makes it a true plug-and-play installation, with no need for expensive scan tools or a visit to the dealer.
How do I provide my VIN number?
After you complete your purchase, simply send us a message with your 17-digit Vehicle Identification Number (VIN). We cannot ship the module until we have this information to program it correctly.
Is this a new or used part?
This is a high-quality, tested component that has been inspected and programmed by our expert technicians to ensure it meets or exceeds OEM specifications for performance and reliability.
What is the difference between part numbers 24272004 and 24276411?
These are interchangeable GM part numbers for the same hardware. Our module is compatible with vehicles that originally came with either part number. The key is the VIN-specific software we install.
Will this fix my P0700 check engine light code?
A P0700 code is a general fault code indicating the TCM has detected a problem. In many cases, a failing TCM is the root cause. Replacing the module with this programmed unit is a very common and effective fix for this code and the underlying issues.
