Is Your Silverado’s Transmission Acting Up?
If your 2007-2013 Chevrolet Silverado is exhibiting symptoms like harsh shifting, delayed gear engagement, or getting stuck in limp mode, the root cause is often a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every shift with precision. When it malfunctions, it can lead to poor performance, decreased fuel economy, and potentially catastrophic transmission damage if left unaddressed. This genuine GM T42 Transmission Control Module, part number 24239224, is the definitive solution to restore your truck’s factory performance and reliability.
From the Diagnostic Bay
We had a 2011 Silverado 1500 come into the shop with the check engine light on and the transmission stuck in 3rd gear. The owner had already replaced two shift solenoids based on some generic trouble codes, but the problem persisted. After a quick scan, we saw the classic P0700 code, which is a general transmission fault request. Digging deeper, we found intermittent communication loss with the TCM. Instead of chasing ghosts, we identified the faulty module. By installing a VIN-programmed 2007-2013 Silverado TCM like this one, we had the truck shifting perfectly in under an hour, saving the customer from further unnecessary parts and labor.
Why a VIN-Programmed 2007-2013 Silverado TCM is Essential
Modern vehicles rely on complex communication between modules. A generic, non-programmed TCM simply won’t work correctly. Our modules are pre-programmed to your truck’s specific Vehicle Identification Number (VIN) before they ship. This crucial step ensures that the module has the latest GM software and is perfectly calibrated for your vehicle’s specific engine, transmission, and tire size. This means no expensive trips to the dealership for programming—it’s a true plug-and-play installation that gets you back on the road faster.

Installation and Compatibility
Replacing the TCM is a straightforward process for a DIY mechanic or a professional technician. On most 2007-2013 Silverado and Sierra models, the TCM is conveniently located in the engine bay, typically next to the battery. Simply disconnect the vehicle’s battery, unplug the electrical connectors from the old module, unbolt it, and install the new one in its place. Reconnect everything, and you’re ready to go. We recommend clearing any stored DTCs with a scan tool after installation for a clean slate. This module is a direct replacement for a wide range of service numbers, including 24252114, 24234503, and 24239224, and fits an extensive list of GM vehicles from 2006-2014 equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E.
Frequently Asked Questions
What does ‘VIN-Programmed’ mean for this TCM?
It means we load your vehicle’s specific VIN into the module before shipping it. This ensures the TCM has the correct software and calibrations for your truck’s exact configuration, allowing it to work perfectly right out of the box without any additional programming.
Do I need to take my truck to a dealer after installing this part?
No. Because the module is pre-programmed to your VIN, you can skip the expensive dealership visit for programming. It is a true plug-and-play solution.
Where is the TCM located on my 2007-2013 Silverado?
On most Silverado and Sierra trucks from this era, the Transmission Control Module is located in the engine compartment, mounted right next to the battery. Always confirm the location on your specific vehicle before beginning work.
Will this module fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a faulty TCM itself can cause this code, it can also be triggered by other transmission issues. However, if you are experiencing other symptoms like erratic shifting or limp mode, a failing TCM is a very common cause.
Is there a core charge for my old part?
No, there is no core charge required for this module. You can keep your old part without the hassle of returning it.
