Restore Peak Transmission Performance in Your GM Truck or SUV
Is your 2007 Chevrolet Silverado 2500 experiencing erratic shifting, delayed gear engagement, or getting stuck in limp mode? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating shift points, managing torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can cause a host of frustrating and potentially damaging issues. This genuine quality T42 TCM, part number 24235732, is the definitive solution to restore your vehicle’s drivability and reliability.
From the Diagnostic Bay
We had a 2007 Sierra 2500 come into the shop with a complaint that stumped a few other mechanics. The owner described intermittent, harsh 1-2 shifts, but only after the truck was fully warmed up. Sometimes it would throw a solenoid code, other times nothing. We checked the fluid, wiring, and solenoids, and everything looked fine. On a hunch, we monitored the TCM data stream during a long test drive. We saw erratic command signals just before the harsh shifts occurred. The internal logic of the original TCM was breaking down under heat. We installed one of our VIN-programmed T42 modules, and the truck has been shifting perfectly ever since. It’s often these subtle electronic failures that cause the biggest headaches.
Common Symptoms of a Failing T42 TCM
- ✔ Harsh, erratic, or delayed gear shifts that disrupt your driving experience.
- ✔ Vehicle suddenly entering ‘limp mode,’ often stuck in 2nd or 3rd gear.
- ✔ The Check Engine Light or Transmission Warning Light is illuminated on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other transmission-related solenoid codes are present.
- ✔ Complete failure to upshift or downshift, leading to poor acceleration and fuel economy.
- ✔ Unexplained loss of communication with the transmission module during scans.

Installation and Compatibility
Installation is straightforward for the DIY mechanic or professional technician. The TCM is typically located in the engine compartment, often next to the battery, on a strut tower, or under the air cleaner box, depending on your specific GM model. The entire process usually takes less than 30 minutes. Simply disconnect the battery, unbolt the old module, disconnect the wiring harnesses, and install the new one. This part is a direct replacement for a wide range of service numbers, including 24252114, 24234503, 24230461, 24235732, and more, making it a versatile fix for many 2006-2014 GM vehicles equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E.
Frequently Asked Questions
What is VIN programming and why is it necessary?
VIN programming involves loading your vehicle’s specific software and calibration files onto the TCM. This is critical because it ensures the module communicates correctly with your engine, ABS, and other systems. Without it, the transmission may not shift correctly, or the vehicle may not start at all. Our pre-programming service makes this a hassle-free, plug-and-play installation.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While a faulty TCM can cause this code, it can also be triggered by other issues like bad solenoids or wiring. However, if you are experiencing other symptoms like erratic shifting along with a P0700, replacing the 2007 Silverado 2500 TCM is a very common and effective solution.
Is this a difficult part to install myself?
For most individuals with basic mechanical skills, this is a very manageable job. The TCM is usually in an accessible location in the engine bay. The primary steps are disconnecting the battery, removing a few bolts, and unplugging the electrical connectors. No special tools are typically required.
Do I need to return my old TCM?
No, there is no core charge for this part. You can keep your old module, which saves you the time and expense of shipping a core back.
