Restore Peak Performance to Your GM Truck or SUV
Is your 2007-2013 Chevrolet Silverado or other GM vehicle suffering from erratic shifting, getting stuck in gear, or displaying transmission-related error 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 smooth gear changes, managing torque converter lockup, and ensuring overall drivetrain efficiency. When it fails, it can lead to a frustrating and potentially unsafe driving experience. This genuine quality T42 TCM, service part number 24252114, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2011 Sierra 1500 come into the shop with the classic complaint: “It feels like it’s getting hit from behind when it shifts.” The customer also mentioned the check engine light was on. A quick scan pulled a P0700 (Transmission Control System Malfunction) and a P0752 (Shift Solenoid ‘A’ Stuck On). While the solenoid code pointed to a specific component, experience told us to check the controller first. After verifying the solenoid’s resistance was within spec, we knew the issue was the T42 TCM providing faulty commands. We installed one of our VIN-programmed modules, cleared the codes, and the truck shifted like it just rolled off the assembly line. The customer was thrilled to have his smooth-shifting truck back without a costly trip to the dealership.
Diagnosing a Faulty Transmission Control Module
A failing TCM can manifest in various ways, often mimicking internal transmission problems. Before condemning your transmission, it’s crucial to recognize the electronic symptoms. A faulty module can send incorrect signals to the solenoids, leading to poor performance that can, over time, cause mechanical damage. Replacing the module promptly is key to preventing more expensive repairs down the road.
Common Symptoms of TCM Failure
- ✔ Harsh & Erratic Shifting: Experiencing sudden, jerky shifts, or a noticeable delay when the transmission engages from park to drive or reverse.
- ✔ Stuck in Limp Mode: The vehicle refuses to shift out of a single gear (often 2nd or 3rd) to protect the transmission from further damage.
- ✔ Warning Lights: Illumination of the Check Engine Light or a specific transmission warning light on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): Common codes include P0700, P0750-P0758 (solenoid circuit faults), and other transmission-specific errors.
- ✔ Poor Fuel Economy: Inefficient shifting and failure of the torque converter to lock up correctly can lead to a significant drop in MPG.
- ✔ No Communication: In severe cases, a scan tool may be unable to communicate with the TCM, indicating a complete module failure.

Frequently Asked Questions
What does a Transmission Control Module (TCM) do?
The TCM is a computer that controls your automatic transmission. It reads data from various sensors on the engine and transmission to determine the perfect moment to shift gears, control hydraulic pressure, and engage the torque converter clutch. This ensures smooth, efficient, and reliable operation.
What does ‘VIN Programmed’ mean for me?
It means the module arrives at your door completely ready to install. We load it with your vehicle’s specific software using your VIN. This eliminates the need for a trip to the dealer for expensive programming, making it a true plug-and-play repair that you can do yourself.
Is this part difficult to install?
For most DIY mechanics, the installation is straightforward. The TCM is typically located in the engine bay (e.g., next to the battery, on the strut tower). The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. The entire job usually takes less than 30 minutes.
Will this fix my specific transmission problem?
This module is a direct solution for issues caused by a faulty TCM, such as electronic shifting errors, communication faults, and specific solenoid circuit codes. If your vehicle’s symptoms match those listed, there is a very high probability this part will resolve the problem. We always recommend proper diagnosis to confirm the TCM is the root cause.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe issues. Poor shifting can cause premature wear on clutches and other internal transmission components, potentially leading to a complete transmission failure that requires a much more expensive mechanical rebuild.
