Restore Peak Transmission Performance in Your GM Vehicle
Are you experiencing frustrating and unpredictable shifting issues with your vehicle? A faulty Transmission Control Module (TCM) is often the culprit behind problems like harsh gear changes, getting stuck in limp mode, or the dreaded check engine light. This genuine GM T42 TCM, service part number 24234503, is the definitive solution for a wide range of 2006-2014 General Motors vehicles, including the Chevrolet Silverado, GMC Sierra, Pontiac G6, and many more. As the electronic brain of your automatic transmission, this module is essential for smooth, efficient, and reliable operation.
From the Diagnostic Bay
We had a 2008 Chevy Tahoe come into the shop stuck in third gear—a classic limp mode symptom. The customer was worried about a complete transmission failure. After a quick scan, we pulled code P0700 (Transmission Control System Malfunction). Instead of jumping to a costly transmission rebuild, we identified the T42 TCM as the point of failure. We installed one of our VIN-programmed modules, cleared the codes, and had the Tahoe shifting perfectly on the test drive. The customer saved thousands and was back on the road in under an hour. This is a common story, and this module is often the simple, effective fix.
Is Your Transmission Control Module Failing?
A failing TCM can manifest in various ways, often mimicking more severe mechanical transmission problems. Before considering a major overhaul, check if your vehicle is exhibiting any of these common symptoms. Replacing the module is a cost-effective first step in diagnostics and repair.
- ✔ Harsh, erratic, or delayed gear shifting.
- ✔ Vehicle is stuck in one gear (limp mode), typically 2nd or 3rd.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes are present.
- ✔ Inability to upshift or downshift properly.
- ✔ A noticeable decrease in fuel economy.
- ✔ The transmission seems to be slipping between gears.
- ✔ Intermittent electrical problems or a complete loss of communication with the transmission.
The Critical Advantage of VIN Programming
What sets our modules apart is the essential VIN programming service, performed before the part ever leaves our facility. We flash the module with your vehicle’s specific Vehicle Identification Number (VIN) and the latest GM software updates. This ensures that the TCM communicates flawlessly with your vehicle’s other computers, like the Engine Control Module (ECM) and Body Control Module (BCM). The result is a true plug-and-play installation that restores original performance and shift strategies without requiring an expensive trip to the dealership for further calibration. This process is key to resolving software-related DTCs and ensuring your transmission operates exactly as the manufacturer intended.

Expert Pro Tip
Before you begin the installation, always disconnect the negative terminal of your vehicle’s battery. This not only prevents accidental electrical shorts but also helps clear any adaptive learning data from the old module, giving your new TCM a fresh start. After installation and reconnecting the battery, use a scan tool to clear any stored DTCs for a clean slate.

Frequently Asked Questions
What is VIN programming and why do I need it?
VIN programming is the process of loading your vehicle’s specific identification number and corresponding factory software onto the transmission control module. This is crucial for ensuring the TCM can communicate correctly with your vehicle’s engine and other systems. Our pre-programming service makes this a plug-and-play part, saving you a trip to the dealership.
Will I need a mechanic to install this part?
Many customers with moderate mechanical skill can install this part themselves in under 30 minutes. The TCM is typically located in an accessible part of the engine bay. However, if you are not comfortable working on your vehicle, we always recommend professional installation.
Is this module compatible with my 2007 Chevy Silverado?
Yes, this T42 TCM is compatible with a vast range of GM vehicles from 2006-2014, including the Silverado, Tahoe, Impala, GMC Sierra, and many more. Please refer to the detailed fitment list on this page to confirm compatibility with your specific year, make, and model.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module, which simplifies the purchasing and installation process for you.
Will this fix a P0700 trouble code?
A P0700 code is a general code indicating the TCM has detected a fault. While this module often resolves the root cause of a P0700 code (especially when paired with other specific transmission codes), you should always perform a full diagnostic. A failing TCM is a very common cause for this code.
