Get Your Workhorse Back on the Job
Is your 2006-2014 GMC Savana 3500 letting you down with unpredictable shifting, getting stuck in gear, or throwing transmission codes? A faulty Transmission Control Module (TCM) can bring your work to a halt, costing you time and money. This is the definitive solution to restore the reliable performance your van needs. Our Programmed 24234503 Transmission Control Module arrives pre-flashed to your vehicle’s specific VIN, eliminating the need for expensive dealership programming and getting you back on the road fast.
Common Symptoms & Your Solution
A failing T42 TCM doesn’t just cause minor annoyances; it compromises the core function of your vehicle. If you’re experiencing any of the following, it’s time for a replacement:
- Harsh, Erratic, or Delayed Shifting: Clunky gear changes or a noticeable lag when the transmission should be shifting.
- Stuck in “Limp Mode”: The vehicle refuses to shift out of a single gear (often 2nd or 3rd) as a protective measure.
- Check Engine & Transmission Lights: Active warning lights on your dash, often accompanied by Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- Poor Performance & Fuel Economy: A struggling transmission can lead to a significant drop in gas mileage and overall sluggishness.
This module is the direct-fit, ready-to-install solution that corrects these issues at their source, restoring the precise electronic control your transmission was designed for.

Expert Insight: The Cost of Downtime
“We had a 2011 Savana 3500 in our fleet that was stuck in limp mode. The driver couldn’t make deliveries, and every hour it was off the road was costing us money. The dealer quoted us a huge bill and a multi-day wait for a new module and programming. We ordered this VIN-programmed TCM instead. It arrived the next day, our mechanic installed it in under 30 minutes, and the van was back in service that afternoon. For a business owner, that’s not just a repair—it’s a lifeline.”
Frequently Asked Questions
What exactly does “VIN Programmed” mean?
It means we flash the module with your vehicle’s unique 17-digit Vehicle Identification Number (VIN) before we ship it. This loads the correct factory software and calibrations for your specific engine, transmission, and options, making it a true plug-and-play part that requires no further setup.
Is this a direct fit for my 2012 GMC Savana 3500?
Yes, this Programmed 24234503 Transmission Control Module is a guaranteed fit for all 2006-2014 GMC Savana 3500 models, as well as a wide range of other GM trucks, vans, and SUVs from that era. It directly replaces service numbers 24242391, 24252114, and others.
Do I need special tools for installation?
No special tools are required. Installation typically involves basic hand tools like a socket set to disconnect the battery and unbolt the module. It’s usually located in an accessible spot in the engine bay, such as on the right-hand side. We recommend disconnecting the battery before starting.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem. While this module often resolves the root cause of a P0700, it’s important to have the vehicle scanned for more specific codes (e.g., P0751, P0756) to confirm the diagnosis. In most cases where the TCM is faulty, this part is the correct fix.
What happens if I don’t replace a failing TCM?
Continuing to drive with a faulty TCM can lead to more severe and expensive damage. It can cause internal transmission components like clutches and solenoids to wear out prematurely, potentially leading to a complete transmission failure that requires a full rebuild or replacement.
Is there a core charge for my old part?
No, there is no core charge required for this part. You can keep your old module without the hassle of returning it, saving you time and money.
