Restore Flawless Performance to Your Cadillac DTS
Is your 2006-2011 Cadillac DTS suffering from erratic shifting, delayed gear engagement, or a persistent check engine light? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every shift with precision. When it falters, it can lead to a cascade of problems, from poor fuel economy to your vehicle being stuck in ‘limp mode.’ This replacement GM T42 TCM, part number 24235754, is the definitive solution to restore the smooth, luxurious ride you expect from your Cadillac.
From the Diagnostic Bay
We recently had a 2008 Cadillac DTS come into the shop with the check engine light on and a complaint of harsh, unpredictable shifting, especially from 1st to 2nd gear. The owner had already replaced two shift solenoids based on a generic code reader’s output, but the problem persisted. Our professional scan tool pulled a P0700 code (Transmission Control System Malfunction) and several intermittent solenoid circuit codes. Instead of throwing more parts at it, we tested the TCM’s communication and power. We found erratic voltage readings at the module. After installing this VIN-programmed T42 TCM, all codes were cleared, and the car shifted like it just rolled off the showroom floor. The issue wasn’t the solenoids themselves, but the module controlling them—a common scenario this part directly resolves.
The Importance of a Programmed 2006-2011 DTS Transmission Module
Modern vehicles like your Cadillac DTS rely on complex communication between various electronic modules. The TCM must be perfectly synced with your vehicle’s specific Vehicle Identification Number (VIN) to function correctly. Our modules are pre-programmed with the latest GM software updates specific to your VIN. This means you can skip the expensive and time-consuming trip to the dealership for programming. It’s a true plug-and-play solution that ensures immediate compatibility and optimal transmission performance right out of the box. This simple step is crucial for resolving communication-based diagnostic trouble codes (DTCs) and ensuring all transmission parameters are set to factory specifications for your exact vehicle build.
Symptoms of a Failing Cadillac DTS TCM
- ✔ Harsh or erratic gear shifts that feel like the transmission is banging into gear.
- ✔ The vehicle gets stuck in a single gear (often 2nd or 3rd), a condition known as ‘limp mode.’
- ✔ Check Engine Light or Transmission Warning Light is illuminated on your dashboard.
- ✔ Diagnostic trouble codes such as P0700, P0750, or other solenoid-related faults are present.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ A noticeable decrease in fuel efficiency due to improper gear selection.
- ✔ Complete failure to shift gears, leaving you stranded.
Easy Installation for DIY and Professionals
Replacing the TCM on your 2006-2011 Cadillac DTS is a straightforward process. The module is located in the right-hand front of the engine compartment. The entire job can typically be completed in under 30 minutes with basic hand tools. Simply disconnect the vehicle’s battery to prevent electrical issues and reset the onboard systems, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Reconnect the connectors and the battery, and you’re ready to go. While the VIN programming handles the critical setup, it’s always a good practice to use a scan tool to clear any stored fault codes after installation. Best of all, there is no core charge, so you don’t have to worry about the hassle of returning your old part.
This module is a direct replacement for a wide range of GM vehicles using the T42 controller and is interchangeable with part numbers including 24252114, 24234503, 24230461, 24235754, and 24242391.

Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming involves loading your vehicle’s specific software and calibration files onto the transmission control module. This ensures the TCM can communicate correctly with your car’s engine computer and other systems. Without it, the transmission may not shift correctly, or the vehicle may not start at all. Our service does this for you, so the part is ready for installation upon arrival.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, this is a very manageable installation. On the 2006-2011 DTS, the TCM is easily accessible in the engine bay. The process involves disconnecting the battery, unplugging a few connectors, and removing a few bolts. No special tools are required.
Will this fix my specific transmission problem?
This module is the solution for a wide range of electronic transmission issues, including erratic shifting, limp mode, and specific TCM-related fault codes (like P0700). While it solves the most common problems, it’s always best to have your vehicle properly diagnosed to confirm the TCM is the root cause.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module, recycle it, or dispose of it as you see fit, saving you the time and expense of a core return.
Is this compatible with other GM vehicles?
Yes, this T42 TCM is used in a wide variety of 2006-2014 General Motors vehicles, including models from Chevrolet, GMC, Buick, Pontiac, and Saturn. However, the programming is specific to the VIN you provide, ensuring it’s a perfect match for your vehicle’s requirements.
