Restore Peak Transmission Performance to Your GM Vehicle
Is your 2006-2014 GMC Savana 2500 experiencing delayed shifts, harsh gear engagement, or is it stuck in limp mode? These are classic signs of a failing Transmission Control Module (TCM). As the central computer for your automatic transmission, a faulty TCM can cause a cascade of problems, from poor fuel economy to a complete inability to shift. This genuine quality T42 TCM, part number 24235732, is the definitive solution, arriving expertly programmed to your vehicle’s specific VIN for a true plug-and-play repair.
From the Diagnostic Bay
We recently serviced a 2010 Chevrolet Express van with a persistent check engine light and erratic shifting. The owner was told he needed a full transmission rebuild. However, our diagnostics pointed to an internal failure within the TCM, which was sending faulty signals to the solenoids. Instead of a multi-thousand dollar repair, we installed this exact VIN-programmed T42 module. The van was back on the road in under an hour, shifting smoothly with no codes, saving the owner significant time and money.

Frequently Asked Questions
What does ‘VIN Programmed’ mean for my vehicle?
VIN programming means we load the module with the specific software and calibrations for your vehicle’s exact make, model, year, and options. This ensures it works seamlessly with your engine and other systems, eliminating compatibility issues and the need for further programming.
Will this TCM fix a P0700 diagnostic trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem and requested the check engine light. While this module often resolves the root cause of the P0700, you should always diagnose any other related codes (like solenoid codes) to ensure a complete repair.
Is any special equipment needed for installation?
Basic hand tools are all that’s required to physically replace the module. After installation, we highly recommend using a standard OBD2 scan tool to clear any stored trouble codes from the vehicle’s memory to complete the process.
Where is the TCM located on my Savana 2500?
On the 2006-2014 Savana and Express vans, the Transmission Control Module is typically located in the engine compartment on the right-hand (passenger) side. Always confirm the location on your specific vehicle before beginning the replacement.
What is the warranty on this part?
This module is backed by a one-year warranty, giving you peace of mind and confidence in the quality and reliability of your repair.
