Get Your Work Van Back on the Road, Fast.
When your Chevrolet Express van’s transmission starts acting up, your entire workday grinds to a halt. Unpredictable shifting, getting stuck in gear, or a glowing check engine light aren’t just annoyances—they’re threats to your schedule and your bottom line. This VIN-programmed T42 Transmission Control Module (TCM) is the definitive solution to get your vehicle operating with the reliability you depend on, eliminating the need for an expensive and time-consuming trip to the dealership.
Common Symptoms & Your Direct Solution
A failing TCM can manifest in several ways, often causing confusion and frustration. If you’re experiencing any of the following, this module is the component you need to restore proper function:
- Harsh, Erratic, or Delayed Shifting: The transmission slams into gear, hesitates, or feels like it’s slipping.
- Stuck in “Limp Mode”: The vehicle is locked in a single gear (usually 2nd or 3rd) with severely limited power.
- Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dash.
- Diagnostic Trouble Codes (DTCs): You’ve pulled codes like P0700 (Transmission Control System Malfunction), P0750, or other solenoid-related faults.
- Poor Performance: A noticeable drop in fuel economy, refusal to upshift or downshift, or a transmission that seems to be overheating.
This pre-programmed module is engineered to resolve these issues directly. By installing our 2006-2014 Express 1500 TCM 24234503, you are replacing the faulty electronic brain of your transmission with a fully updated and vehicle-specific unit, ensuring precise communication and flawless operation from the moment you plug it in.

Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles, the TCM doesn’t just change gears; it’s in constant communication with the Engine Control Module (ECM), ABS, and other vehicle systems. Generic, non-programmed modules can’t properly interpret this data stream, leading to persistent shifting problems, incorrect performance, or even complete communication failure. Our VIN-specific programming loads your vehicle’s exact factory calibration file onto the module. This ensures it knows everything from the engine size and axle ratio to the tire size, allowing it to make perfect decisions for every shift. Installing a correctly programmed 2006-2014 Express 1500 TCM 24234503 is the only way to guarantee a successful and lasting repair.
Frequently Asked Questions
Do I need to take my vehicle to a dealer after installation?
Absolutely not. The primary benefit of this module is that it comes fully programmed to your vehicle’s VIN. This eliminates the need for any additional on-vehicle programming. It is a true plug-and-play solution.
What does a Transmission Control Module (TCM) actually do?
The TCM is the dedicated computer for your automatic transmission. It receives data from various sensors on the engine and transmission to control shift solenoids, manage torque converter lockup, and regulate fluid pressure. A faulty TCM is the cause of most electronic transmission problems.
Is installation difficult? Can I do it myself?
For someone with basic mechanical skills, installation is straightforward and typically takes less than 30 minutes. The TCM is usually located in the engine compartment. Disconnecting the battery before you begin is the most important step. After installation, you can use a basic OBD-II scanner to clear any stored fault codes.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep or dispose of your old module without the hassle of returning it.
How do I provide my VIN for programming?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy, as this is critical for correct programming.
