If your 2007-2013 Silverado 1500 is suffering from erratic shifting, getting stuck in gear, or throwing transmission codes, you’ve likely pinpointed the culprit: a failing Transmission Control Module (TCM). As a technician with over two decades of experience, I’ve seen firsthand how a faulty TCM can sideline an otherwise perfectly good truck. The constant, harsh banging into gear or the dreaded ‘limp mode’ isn’t just annoying—it’s a sign that the brain of your transmission is malfunctioning, putting unnecessary stress on expensive mechanical parts.
This isn’t a part you can afford to ignore. The T42 TCM is the central command for your 4L60E, 4L65E, or 4L70E automatic transmission. It precisely controls shift points, torque converter lockup, and line pressure. When it fails, you get the symptoms you’re likely experiencing right now. This replacement part, number 24235753, is the definitive solution. We take the hassle and high cost of dealership visits out of the equation by pre-programming it to your truck’s specific Vehicle Identification Number (VIN). This ensures it works seamlessly with your vehicle’s systems right out of the box—no expensive specialty tools or software subscriptions required.
From the Diagnostic Bay
I remember a 2011 Silverado 1500 that came into my shop. The owner was frustrated; he’d already replaced two shift solenoids based on a P0750-series code, but the harsh 1-2 shift and intermittent ‘Transmission Hot’ message persisted. A quick data stream check showed erratic commands from the TCM. The internal circuitry was failing, sending faulty signals. We installed one of our VIN-programmed T42 modules. In under 30 minutes, the truck was back on the road, shifting like it just left the factory. It’s a classic case where chasing individual codes can be misleading; the root cause is often the module itself.
Is Your Silverado Showing These Telltale TCM Failure Signs?
A failing 2007-2013 Silverado 1500 Transmission Control Module often presents clear symptoms. Check if any of these match your experience:
- ✔️ Harsh, delayed, or unpredictable gear shifts.
- ✔️ Vehicle is stuck in one gear (often 2nd or 3rd), also known as ‘limp mode’.
- ✔️ Check Engine Light or Transmission Warning Light is illuminated.
- ✔️ Diagnostic Trouble Codes (DTCs) are present, such as P0700 (Transmission Control System Malfunction), P0751, P0756, or other solenoid-related faults.
- ✔️ A complete loss of shifting ability or failure to engage a gear from park.
- ✔️ Poor fuel economy and a feeling of sluggish performance.
Quick & Easy TCM Installation Guide
This is a repair you can confidently tackle in your own driveway. For most Silverado 1500 models, the TCM is located in the engine bay, typically next to the battery. The entire process should take less than half an hour.
- Safety First: Disconnect the negative terminal from your truck’s battery to prevent any electrical shorts and help reset the vehicle’s adaptive memory.
- Locate the Module: Find the TCM mounted near the battery or under the air cleaner box. It will have several large electrical connectors attached.
- Disconnect and Remove: Carefully unplug the electrical connectors. They have locking tabs that need to be released. Once disconnected, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place. Reconnect the electrical connectors, ensuring they click securely into position.
- Final Steps: Reconnect the negative battery terminal. While the module is plug-and-play, it’s good practice to use a basic OBD2 scan tool to clear any stored fault codes from the system. Start the vehicle and enjoy smooth shifting!

Why is VIN programming so important for a TCM?
Why is VIN programming so important for a TCM?
VIN programming loads your vehicle’s specific software, including shift strategies, torque limits, and tire size calibrations, onto the module. Without it, the TCM won’t communicate correctly with the Engine Control Module (ECM) and other vehicle systems, leading to persistent shifting problems or a no-start condition. Our pre-programming service saves you a mandatory, and often expensive, trip to the dealership.
Will this part fix a P0700 trouble code?
A P0700 code is a general fault request from the TCM to the ECM to turn on the Check Engine Light. It means the TCM has stored its own specific codes (like for a solenoid or sensor). While a faulty TCM is a very common cause for a P0700, proper diagnosis is key. However, if you’re also experiencing the physical symptoms of failure, replacing the TCM is often the correct repair.
Is there a core charge? Do I have to return my old TCM?
No, there is absolutely no core charge for this part. You can keep your old module or dispose of it responsibly without any hassle or need to send it back to us.
