Restore Your Cadillac’s Signature Smoothness
Is your Cadillac’s transmission shifting erratically, hesitating between gears, or unexpectedly dropping into limp mode? These are frustrating issues that undermine the luxury and performance you expect. Restore the precise, responsive shifting your vehicle was built for with our VIN-programmed Transmission Control Module (TCM). This isn’t just a replacement part; it’s a comprehensive solution designed to get you back on the road with confidence and eliminate the guesswork of a complex repair.

- Harsh or delayed shifting, especially the common hard 1-2 shift.
- Slipping between gears or failure to engage.
- The vehicle entering a “limp mode,” stuck in a single gear.

Expert Insight: The Critical Role of VIN Programming
Why is VIN-programming so critical? The TCM is the ‘brain’ of your 5L40E transmission. It constantly communicates with the Engine Control Module (ECM), ABS, and dozens of sensors. Without the exact software for your Cadillac’s specific options and build, you’ll face persistent communication errors and performance issues. Our process isn’t just about loading a generic file; it’s about matching the module’s digital DNA to your vehicle, ensuring a seamless integration that dealerships charge hundreds for. This is the key to a lasting, reliable repair.
Frequently Asked Questions
Do I need to take this part to the dealer for programming?
Absolutely not. We handle all the programming before we ship. This 2004-2005 Cadillac CTS TCM 24229790 will arrive at your door flashed with the latest GM updates specific to your vehicle’s VIN, making it ready for installation.
Where do I provide my vehicle’s VIN?
After you complete your purchase, you will need to send us your 17-digit Vehicle Identification Number (VIN). We cannot ship your order until we receive this information, as it is essential for the programming process.
Is this a simple plug-and-play installation?
Yes, for the most part. The module is a direct physical replacement located in the right-hand front of the engine compartment. Once installed, the pre-programming ensures it communicates correctly. However, for optimal performance, some vehicles may benefit from a transmission fluid service and a relearn procedure, which can be performed by a qualified technician.
How can I be sure my TCM is the problem?
The symptoms listed above—like harsh shifting, limp mode, and specific transmission codes—are strong indicators of a failing TCM. However, we always recommend a full diagnosis by a professional mechanic to rule out other potential issues like faulty wiring, solenoids, or mechanical transmission problems.
Will this fit my 2006 Cadillac SRX?
Yes, this module fits the 2006 SRX with either the 3.6L engine or the 4.6L engine that used the original ID 24229791. It is also the correct fit for all 2004-2005 CTS and SRX models.
