Restore Your Vehicle’s Flawless Shifting
Are you experiencing frustrating and unpredictable transmission behavior in your Cadillac or Pontiac? An illuminated check engine light, harsh shifting, or the vehicle getting stuck in gear are more than just annoyances—they are signs that the electronic brain of your transmission has failed. This pre-programmed 24239785 Transmission Control Module is the definitive solution, designed to restore the smooth, responsive, and reliable performance you expect from your vehicle, getting you back on the road with confidence.

Our expert-programmed 24239785 Transmission Control Module directly addresses these issues. We flash the unit with the latest official GM software, specifically matched to your vehicle’s unique Vehicle Identification Number (VIN).

Expert Insight: The Critical Role of VIN Programming
For modern vehicles like the Cadillac STS, CTS, SRX, or the Pontiac Solstice and Sky, the TCM is not a one-size-fits-all part. These vehicles have numerous factory options—from engine size to all-wheel-drive systems—that dictate the precise shifting strategy. Programming this 24239785 Transmission Control Module with your VIN isn’t just a convenience; it’s a necessity. It tells the module exactly how to operate for your specific build, ensuring optimal shift points, torque converter lockup, and electronic pressure control for a seamless and durable repair.
Frequently Asked Questions
Why do I need to provide my VIN?
Your Vehicle Identification Number (VIN) allows us to load the exact software and calibration file that your vehicle requires from the GM factory. This ensures the module communicates perfectly with your car’s specific engine, options, and other computers for a true plug-and-play installation.
Is this part difficult to install?
The physical installation is a direct replacement, typically straightforward for a qualified mechanic. The module is located on the LH front frame rail on Sky/Solstice models, the RH front engine compartment on the SRX, and on the RH side of the dash for STS/CTS transfer case applications. The primary benefit is that once installed, no further programming is needed.
Will this fix my specific shifting problem?
This module is the most common solution for a wide range of electronic transmission faults, including harsh shifting, error codes, and communication issues. While it resolves the vast majority of these problems, we always recommend a proper diagnosis by a professional technician to confirm the TCM is the root cause.
What happens after I place my order?
After you complete your purchase, you will need to send us your 17-digit VIN. Our technicians will then program the module with the latest GM software matched to your vehicle. Once programming is complete, we will carefully package and ship the unit to you.
Does this part require any additional programming after installation?
No. The unit arrives completely programmed and ready for installation. Once it is installed in the vehicle, it is ready to go. There is no need for a trip to the dealer or the use of a specialized scan tool for programming.
How does the one-year replacement warranty work?
