Is Your Silverado’s Transmission Acting Up?
If you’re experiencing erratic shifting, delayed gear engagement, or your 2007-2013 Silverado 1500 is stuck in limp mode, a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for every gear change, torque converter lockup, and line pressure adjustment. When it fails, it can mimic the symptoms of a catastrophic transmission failure, leading to costly misdiagnoses. This genuine quality T42 TCM, service number 24235340, is the definitive solution to restore your truck’s performance and reliability.
From the Diagnostic Bay
We had a 2011 Silverado 1500 towed in last month. The owner was convinced his 4L60E transmission was completely shot. It was slamming into gear and the check engine light was on with a P0700 code. Another shop had quoted him over $3,000 for a transmission rebuild. After a quick scan, we saw several solenoid circuit codes that were all pointing to an internal TCM fault. Instead of a rebuild, we installed one of these VIN-programmed T42 modules. In under an hour, the truck was shifting perfectly, all codes were cleared, and the customer saved thousands. It’s a classic case of the brain failing, not the body.
Symptoms of a Failing GM T42 TCM
A faulty TCM can manifest in various ways, often intermittently at first. If you notice any of the following issues, it’s time to inspect your transmission control module. Ignoring these signs can lead to further damage to your transmission’s mechanical components.
- ✔ Harsh, erratic, or delayed gear shifts.
- ✔ The vehicle gets stuck in one gear (often 2nd or 3rd), known as “limp mode”.
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related codes are present.
- ✔ Failure to upshift or downshift properly.
- ✔ A noticeable decrease in fuel economy.
- ✔ The transmission seems to slip between gears.
- ✔ Complete loss of communication with the module, preventing diagnostics.

Frequently Asked Questions
What is VIN programming and why is it important?
VIN programming involves loading your vehicle’s specific software and calibration files onto the TCM before it is shipped. This ensures the module works perfectly with your truck’s engine, options, and tire size right out of the box, just as the original did. It eliminates the need for expensive dealership tools for installation.
Do I need to take my truck to a dealer after installing this?
No. Because this module is pre-programmed to your VIN, no further programming or dealership visits are required. It is a true plug-and-play installation. We do recommend clearing any old trouble codes with a standard scan tool after installation.
Where is the TCM located on my 2007-2013 Silverado?
On the 2007-2013 Silverado and Sierra pickups, the T42 TCM is typically located in the engine compartment, mounted next to the battery. Always disconnect the battery’s negative terminal before beginning the replacement.
Will this module fix a P0700 trouble code?
A P0700 code is a general transmission fault request from the TCM to the Engine Control Module (ECM) to turn on the check engine light. While this module often resolves the underlying issue causing the P0700, you should scan for more specific P-codes (like solenoid or sensor codes) to confirm the TCM is the root cause.
Is there a core charge for this part?
No, there is no core charge required for this transmission control module. You can keep your old part without any hassle or need to return it.
