Restore the Signature Performance of Your Cadillac
The sophisticated performance of your Cadillac XLR or STS is defined by its seamless power delivery and responsive shifting. When erratic gear changes, hesitation, or dashboard warning lights appear, it compromises the entire driving experience and can be a source of constant worry. This isn’t just an inconvenience; it’s a sign that your vehicle’s core logic is failing. We offer a precise and reliable solution: a professionally programmed Transmission Control Module (TCM) engineered to restore your vehicle’s original character and performance.
Common Symptoms & Your Definitive Solution
A failing TCM can manifest in several frustrating ways. If you’re experiencing any of the following, a faulty module is the likely culprit:
- Harsh, delayed, or erratic shifting
- Vehicle getting stuck in one gear (Limp Mode)
- Illuminated Check Engine Light or other transmission-related warnings
- Diagnostic Trouble Codes (DTCs) such as P0700, P0751, P0756, or U0101
- Poor fuel economy and reduced engine performance
This is the definitive fix. We take a genuine OEM-spec TCM (compatible with part numbers 24222734, 24229789, and 24240283) and flash it with the very latest General Motors software updates, specifically calibrated to your car’s unique Vehicle Identification Number (VIN). This process ensures that your new 2004-2005 Cadillac XLR TCM communicates flawlessly with the engine and other vehicle systems, correcting the root cause of your transmission problems.

An Expert’s Note on Modern Vehicle Electronics
In vehicles like the Cadillac XLR and STS, the TCM is more than just a simple controller; it’s a critical node in a complex communication network. A generic, non-programmed module simply cannot function correctly. It will fail to communicate with the Engine Control Module (ECM), Body Control Module (BCM), and other systems, leading to persistent errors or even a no-start condition. Our VIN-programming service isn’t just a convenience—it’s an essential step to ensure the repair is done right the first time, preserving the intricate engineering of your luxury vehicle.
Frequently Asked Questions
How do I provide my vehicle’s VIN?
After you complete your purchase, you can add your 17-digit VIN to the order notes section at checkout. If you miss it, we will contact you via email to request it before we can program and ship your 2004-2005 Cadillac XLR TCM.
Is this part truly plug-and-play?
Yes. Because we pre-program the module to your specific VIN, it is designed to be a plug-and-play installation. Once installed, your vehicle will recognize it as the correct component, saving you a costly trip to the dealership for additional programming.
Will this fix my specific transmission problem?
This TCM is the direct solution for failures within the module itself. If your vehicle is displaying symptoms like erratic shifting, communication error codes (U-codes), or specific TCM-related P-codes, this part is very likely the solution. However, we always recommend having a professional mechanic confirm the diagnosis to rule out mechanical issues within the transmission.

What kind of warranty is included?
