Is Your Silverado’s Transmission Acting Unpredictably?
If you’re dealing with harsh shifting, delayed gear engagement, or a transmission warning light on your 2007 Chevrolet Silverado 2500, a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your 4-speed automatic transmission (like the 4L60E, 4L65E, or 4L80E), responsible for every gear change and torque converter operation. When it fails, it can cause a wide range of frustrating and potentially damaging issues, from poor fuel economy to being stuck in ‘limp mode’.
This genuine GM T42 Transmission Control Module, part number 24240449, is the definitive solution. We take the guesswork and high dealership costs out of the equation by pre-programming the module to your truck’s specific Vehicle Identification Number (VIN). This ensures it works perfectly right out of the box, restoring the smooth, reliable performance you expect from your truck.
From the Diagnostic Bay
We had a 2007 Sierra come in with classic symptoms—banging into gear and a P0752 code for Shift Solenoid A Stuck On. The owner had already replaced the solenoid twice with no luck. After a quick diagnostic, we confirmed the solenoid circuit was fine. The real issue was the driver circuit inside the original TCM. We installed one of our VIN-programmed T42 modules, cleared the codes, and the truck was shifting perfectly within 20 minutes. It’s a common scenario where the module itself is the root cause, not the components it controls.
Why Choose Our Pre-Programmed 2007 Silverado 2500 TCM?
Getting your truck back to peak condition shouldn’t involve a complicated, expensive trip to the dealer. Our process is designed for the professional technician and the skilled DIYer. By programming the module with the latest GM software updates before it ships, we eliminate the need for specialized scan tools or costly programming services. This is a true plug-and-play component that directly addresses common transmission Diagnostic Trouble Codes (DTCs) and performance problems associated with a faulty 2007 Silverado 2500 TCM.
Symptoms of a Failing T42 TCM
- ✔ Harsh, erratic, or delayed shifting that makes driving uncomfortable.
- ✔ The vehicle gets stuck in a single gear (often 2nd or 3rd), known as limp mode.
- ✔ Check Engine Light or Transmission Warning Light is illuminated on the dash.
- ✔ Your scan tool shows transmission-specific codes like P0700, P0750, P0751, or other solenoid-related faults.
- ✔ A noticeable drop in fuel efficiency due to improper gear selection.
- ✔ Complete loss of communication with the transmission module, leading to a no-start or no-shift condition.
Simple Installation, Lasting Results
Installation is straightforward. On the 2007 Silverado 2500, the TCM is typically located in the engine compartment, next to the battery. The process generally takes less than 30 minutes.
- Disconnect the Battery: Always disconnect the negative battery terminal before working on vehicle electronics.
- Locate and Replace: Unplug the wiring harnesses from the old module, unbolt it, and install the new one in its place.
- Reconnect and Clear: Reconnect the harnesses and the battery. Use a standard OBD2 scan tool to clear any stored DTCs.
- Test Drive: Take your truck for a drive to confirm that shifting has returned to normal.

Frequently Asked Questions
Is this TCM really plug-and-play?
Yes. We program the module to your vehicle’s VIN before shipping. This means it has the correct software and calibration for your specific truck, allowing you to install it without any additional programming from a dealership.
Where is the TCM located on my 2007 Silverado 2500?
For the 2007 Silverado 2500 (new body style), the Transmission Control Module is typically found in the engine bay, mounted next to the battery.
Will this fix transmission error codes like P0700?
A P0700 code is a general fault request from the TCM to the Engine Control Module (ECM) to turn on the check engine light. This module will fix the underlying issue that caused the P0700, such as solenoid circuit faults (e.g., P0750-P0758), as long as the fault is within the module itself and not the wiring or solenoids.
What is the difference between a TCM and an ECM?
The Engine Control Module (ECM) manages engine functions like fuel injection and ignition timing. The Transmission Control Module (TCM) specifically manages the automatic transmission’s functions, such as when to shift gears and when to lock the torque converter. They work together but are separate computers.
Do I need to send my old part back?
No, there is no core charge for this part. You can keep or dispose of your old module, making the replacement process hassle-free.
