Restore the Signature Smoothness to Your Cadillac DTS
As a technician with over two decades of experience, I know that owning a Cadillac DTS is about appreciating a smooth, powerful, and luxurious ride. When your transmission starts acting up—with harsh shifts, delayed gear engagement, or warning lights on the dash—it doesn’t just disrupt your drive; it compromises the very essence of your vehicle. A faulty Transmission Control Module (TCM) is often the culprit, causing communication breakdowns that lead to poor performance and potential transmission damage. This is a common issue I’ve diagnosed hundreds of times on GM front-wheel-drive platforms.
This isn’t just a replacement part; it’s a direct solution. We offer a high-quality T42 2006-2011 DTS Transmission Module, meticulously programmed to your vehicle’s specific VIN. This crucial step ensures the module communicates flawlessly with your engine computer and other vehicle systems right out of the box. You can bypass the expensive dealership visit for programming and get your Cadillac back to shifting with the quiet precision you expect. It’s the reliable fix for restoring performance and peace of mind.
From the Diagnostic Bay: The Case of the Hesitant DTS
A client brought in his 2009 Cadillac DTS, complaining of intermittent, jarring shifts, especially after driving for 20-30 minutes. He also mentioned a loss of power and that the car once felt stuck in a single gear. My scan tool pulled a generic P0700 (Transmission Control System Malfunction). In my experience, these heat-related, intermittent symptoms on the DTS almost always point back to the TCM. The internal electronics become sensitive to temperature changes over time, causing erratic signals to the solenoids. We installed one of our VIN-programmed modules, and the problem was solved on the first test drive. The client was thrilled to have his smooth, responsive Cadillac back without a costly diagnostic chase.
Is Your DTS Showing These Telltale Signs?
A failing TCM will give you clear warnings. If you’re experiencing any of the following, it’s time to consider a replacement:
- ✔ Unpredictable or harsh shifting between gears.
- ✔ The vehicle feels like it’s stuck in “limp mode” (usually 2nd or 3rd gear).
- ✔ Check Engine Light or “Service Transmission” warning is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750-P0758 (solenoid circuit faults), or other transmission-related codes.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Noticeable decrease in fuel economy.

- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the vehicle’s adaptive memory.
- Locate the Module: On the Cadillac DTS, the TCM is typically found in the right-hand (passenger side) front engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Press the release tabs firmly. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed module into place. Reconnect the electrical harnesses, ensuring they click securely into position.

Frequently Asked Questions
What does “VIN programmed” mean for my Cadillac?
It means we load your vehicle’s unique Vehicle Identification Number (VIN) and the latest GM software onto the module before shipping. This ensures it communicates perfectly with your car’s specific systems, eliminating the need for an expensive programming appointment at a dealership.
Will this fix a “Service Transmission” message on my DTS?
Yes, if the message is caused by a failing transmission control module, this part is the direct solution. It’s designed to resolve the electronic faults that trigger that specific warning and related trouble codes.
Where is this module located on a 2006-2011 Cadillac DTS?
The TCM on the Cadillac DTS is conveniently located in the engine bay, specifically in the front right-hand (passenger side) area. This makes it much easier to access than modules located inside the transmission.
Do I need any special tools for this installation?
No special tools are required. Basic hand tools, such as a socket set to remove the mounting bolts and a tool to disconnect the battery, are all you need. A code scanner is recommended to clear old codes but is not required for the module to function.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, saving you time and shipping costs.
