Restore Flawless Shifting to Your Cadillac
Are you battling with erratic shifting, a check engine light, or a transmission that seems to have a mind of its own? A faulty Transmission Control Module (TCM) is often the culprit, turning your smooth-driving Cadillac CTS into a source of frustration. As the electronic brain of your automatic transmission, the TCM dictates every gear change. When it fails, you experience everything from harsh, jerky shifts to being stuck in one gear, compromising both performance and safety. This replacement 2016 CTS Transmission Module is the definitive solution, arriving pre-programmed and ready for installation.
From the Diagnostic Bay
I remember a 2016 Cadillac CTS that came into my shop with a classic complaint: “It slams into gear, especially after it’s warmed up.” The customer was worried about a catastrophic transmission failure. After hooking up the scanner, I saw a U0101 (Lost Communication with TCM) code and some erratic pressure control solenoid data. Instead of jumping to a full transmission rebuild, we checked the TCM. Sure enough, heat soak was causing internal electronic failure. We swapped in a VIN-programmed module just like this one. The total time from diagnosis to test drive was under two hours. The customer drove away with a car that shifted like new, saving thousands over a dealership repair.
Is Your GM Vehicle Showing These Symptoms?
- ✔ Harsh or delayed gear engagement.
- ✔ The vehicle getting stuck in a single gear (limp mode).
- ✔ An illuminated Check Engine Light or Transmission Warning Light.
- ✔ Common diagnostic trouble codes (DTCs) such as P0700, P0751, or U0101.
- ✔ Unpredictable downshifting or upshifting.
- ✔ Poor fuel economy directly related to inefficient shifting.
The Advantage of a Pre-Programmed 2016 CTS Transmission Module
The biggest hurdle in replacing a modern TCM is the need for specialized programming. Dealerships charge a premium for this service, adding significant cost and downtime to your repair. We eliminate that step entirely. By providing us with your vehicle’s VIN during checkout, you receive a module that is loaded with the latest GM-certified software specific to your car. This makes the replacement process straightforward for a professional mechanic or a confident DIY enthusiast. It’s a direct-fit solution designed to restore the precise, factory-spec performance you expect from your vehicle.
A Straightforward Guide to Installation
- ✔ Safety First: Always disconnect the negative terminal from your vehicle’s battery before beginning any electronic component replacement.
- ✔ Locate the TCM: On the 2016 CTS, the TCM is typically found on the LH (driver’s side) front rail. For other compatible vehicles, it may be on the radiator support or fan shroud. Refer to a service manual for your specific model if you’re unsure.
- ✔ Disconnect Connectors: Carefully unclip the wiring harness connectors from the old module. Inspect the connectors for any signs of corrosion or damage and clean them if necessary.
- ✔ Remove the Old Module: Unbolt the mounting hardware securing the old TCM to the vehicle frame or bracket. Note the orientation of the module.
- ✔ Install the New Module: Mount your new, pre-programmed TCM in the same location and orientation as the original. Secure it with the original hardware.
- ✔ Reconnect and Finalize: Firmly re-attach the wiring harness connectors until they click into place. Reconnect the negative battery terminal. It may be necessary to perform a transmission adaptive pressure relearn procedure with a capable scan tool for optimal performance.

Frequently Asked Questions
How does the VIN programming process work?
It’s simple. After you complete your purchase, you will provide us with your 17-digit Vehicle Identification Number (VIN). Our technicians use this VIN to access the latest GM software for your specific vehicle and flash it directly onto the module before it ships. This ensures perfect compatibility right out of the box.
Is this a plug-and-play part?
Yes, because we program it to your VIN, it is designed to be a plug-and-play solution. It eliminates the need for a trip to the dealership for programming. In some cases, a transmission adaptive pressure relearn procedure may be recommended for the smoothest possible operation, which can be done by most professional scan tools.
Do I need to send my old TCM back (core charge)?
No, there is no core charge for this part. You can keep or responsibly dispose of your old module without needing to send it back to us.
Will this fix my transmission problems?
If your vehicle’s issues, such as harsh shifting or error codes like U0101, have been properly diagnosed as a faulty TCM, then this part is the correct solution. It’s designed to resolve all issues directly caused by a failing transmission control module.
What is the difference between part numbers 24272004 and 24276411?
These are interchangeable GM part numbers for the same hardware. Our module is a direct replacement for either number, and the specific VIN programming we perform ensures it functions correctly for your application, regardless of which of these two part numbers was originally installed.
