Restore Your Cadillac’s Signature Smoothness
Is your Cadillac DTS no longer delivering that smooth, luxurious ride you expect? Harsh shifting, hesitation between gears, or a sudden check engine light can be incredibly frustrating, turning a refined driving experience into a source of stress. These are classic signs of a failing Transmission Control Module (TCM). This pre-programmed T42 TCM is the definitive solution, engineered to restore your vehicle’s precise shifting and get you back on the road with confidence.

Expert Insight: The Critical Role of VIN Programming
In a sophisticated vehicle like a Cadillac DTS, the TCM doesn’t just change gears—it’s part of a complex network of modules that constantly communicate.

Our VIN-specific programming loads the exact software and calibration files GM intended for your vehicle’s unique configuration. This ensures the new 2006-2011 Cadillac DTS transmission control module integrates perfectly, not just making the transmission work, but making it work right.

Frequently Asked Questions
What does a VIN-programmed TCM actually do?
VIN programming loads your vehicle’s specific software and calibration data onto the module before it ships. This ensures it communicates perfectly with your car’s engine computer and other systems, just like the original part from the factory, eliminating the need for a costly trip to the dealership for setup.
Is this a difficult part to install?
For someone with moderate mechanical experience, the installation is straightforward. The TCM is typically located in the engine compartment and can be replaced in under an hour. We recommend disconnecting the battery before starting and using a scan tool to clear any stored codes after installation.
Will this fix my transmission warning light?
Yes, if the warning light and associated codes (like P0700) are being caused by a faulty TCM, this part is designed to be the direct solution. Once installed, the communication errors that triggered the light should be resolved.
How do I know for sure that my TCM is failing?
Common signs include erratic shifting, getting stuck in one gear (limp mode), and specific transmission-related diagnostic trouble codes. While other issues can cause similar symptoms, these are the most definitive indicators of a failing TCM.
Do I need to send my old part back?
No core charge is required for this module. You can keep your old part, avoiding the hassle and expense of a core return process.
What other vehicles is this T42 module compatible with?
This T42 TCM is compatible with a wide range of 2006-2014 GM vehicles, including models like the Chevrolet Tahoe, Silverado, Impala; GMC Yukon and Sierra; Buick LaCrosse and Lucerne; and many others equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E.
