Restore Peak Transmission Performance in Your GM Truck or SUV
Is your 2007-2013 Chevrolet Silverado 1500, Tahoe, or another GM vehicle suffering from erratic shifting, getting stuck in gear, or displaying transmission-related trouble codes? 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 gear change, managing torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can cripple your vehicle’s performance and leave you stranded. This genuine OEM-quality T42 TCM, part number 24240400, is the definitive solution, pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
From the Diagnostic Bay
We recently had a 2011 GMC Sierra in the shop with a classic complaint: harsh 1-2 shifts and occasional failure to shift out of 3rd gear. The owner had already spent a small fortune replacing shift solenoids based on a generic code reader’s output, but the problem persisted. After a quick scan with our professional equipment, we identified communication errors pointing directly to the TCM. The internal logic circuits had failed. We installed one of our VIN-programmed T42 modules, cleared the adaptive learning tables, and the truck was shifting like new in under an hour. It’s a powerful reminder that chasing individual solenoid codes can be a costly distraction when the central controller is the real culprit.
Diagnosing a Faulty 2007-2013 Silverado 1500 TCM
A failing TCM doesn’t always lead to a complete transmission breakdown immediately. It often starts with subtle, intermittent issues that worsen over time. Recognizing these symptoms early can save you from more extensive and costly transmission damage. This module is the correct fix for a wide range of issues affecting not just the Silverado, but also the GMC Sierra, Chevrolet Tahoe, Suburban, and many other vehicles equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E.
Common Symptoms of TCM Failure
- ✔ Erratic and Harsh Shifting: Your vehicle may slam into gear, hesitate between shifts, or shift at incorrect RPMs.
- ✔ Stuck in Limp Mode: The transmission may refuse to shift, often getting stuck in 2nd or 3rd gear to prevent further damage.
- ✔ Warning Lights: The Check Engine Light or a dedicated transmission warning light will illuminate on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): You’ll often see codes like P0700 (Transmission Control System Malfunction) or specific solenoid circuit codes (e.g., P0751, P0756).
- ✔ Delayed Engagement: A noticeable delay when shifting from Park into Drive or Reverse.
- ✔ Poor Fuel Economy: Inefficient shifting and torque converter lockup problems can cause a significant drop in MPG.
The Plug-and-Play Advantage: VIN Programming Included
One of the biggest hurdles in replacing modern vehicle electronics is the need for expensive dealership programming. We eliminate that step entirely. Before this module ships, we program it with your vehicle’s unique 17-digit VIN and load the latest GM software calibrations. This ensures that the TCM communicates flawlessly with your vehicle’s Engine Control Module (ECM) and other systems right out of the box. There’s no need for a trip to the dealer or a special scan tool for setup. Simply install the part, connect your battery, and drive away.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we flash the module with the specific software and calibration file that matches your vehicle’s exact factory build, using your Vehicle Identification Number (VIN). This ensures the TCM works perfectly with your truck’s engine, tire size, and gear ratios, eliminating compatibility issues.
Do I need to take my truck to a dealer after installing this part?
No. Because the unit is pre-programmed to your VIN, no further dealership programming or setup is required. It is a true plug-and-play solution.
Where is the TCM located on my 2011 Silverado 1500?
On most 2007-2013 Silverado and Sierra 1500 models, the T42 TCM is located in the engine bay, typically mounted next to the battery on a dedicated bracket.
Will this module fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem and has requested the Check Engine Light to be turned on. While this module will fix the issue if the TCM itself is the source of the problem, you should always diagnose any other codes that are present alongside the P0700 to ensure there isn’t a separate sensor or wiring issue.
Is there a core charge for this part?
No, we do not require a core charge. You can keep your old part without needing to send it back, simplifying the repair process for you.
