Get Your Work Van Back on the Road, Fast
Is your 2006-2014 GMC Savana 3500 experiencing harsh shifting, getting stuck in gear, or throwing transmission codes? A faulty Transmission Control Module (TCM) can bring your workday to a grinding halt, costing you time and money. This VIN-programmed T42 TCM is the direct-fit, professional-grade solution to restore your van’s reliability and get you back on the job without a costly trip to the dealership.
Common Symptoms & Your Solution
When a TCM begins to fail, it can cause a range of serious issues that make your vehicle unreliable or even undrivable. If you’re noticing any of the following problems, this module is the definitive fix:
- Harsh, erratic, or delayed gear shifts
- Vehicle stuck in “limp mode” (usually 2nd or 3rd gear)
- Check Engine Light or Transmission Warning Light is on
- Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related faults
- Failure to upshift or downshift properly
- Poor fuel economy and transmission overheating
Installing our pre-programmed Savana 3500 TCM 24252114 directly addresses these issues by restoring precise communication between your engine and transmission, ensuring your van operates exactly as it should.

Expert Insight: The Critical Role of VIN Programming
For a work vehicle like the Savana 3500, downtime is lost revenue. The single biggest advantage of this module is the VIN-specific programming done before it ships. A generic, unprogrammed TCM would require a tow to a dealership and several hours of labor for flashing. Our process ensures the module has the latest GM software and is perfectly calibrated to your vehicle’s specific options and transmission type (like the 4L80E). This turns a potentially complex, multi-day repair into a straightforward job you can complete in your own garage or shop in under an hour.
Frequently Asked Questions
What does a VIN-programmed TCM actually do?
VIN programming loads your vehicle’s specific software onto the module. This ensures it communicates correctly with the engine computer and other systems, controlling shift points, torque converter clutch engagement, and fluid pressure for optimal performance and fuel efficiency, just as the factory intended.
Is this a difficult part to install?
No, this is a straightforward installation for a DIYer with basic tools or any professional mechanic. The TCM is typically located in the engine compartment on the RH side. The process involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. Because it’s pre-programmed, no further steps are needed.
Will this fix my P0700 error code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause, it’s essential to have the transmission scanned for more specific codes (like solenoid or sensor faults) to confirm the TCM is the issue. This part is designed to fix internal TCM failures that trigger these codes.
Do I need to send my old part back?
No. We do not require a core return for this Savana 3500 TCM 24252114. You can keep or dispose of your old part at your convenience, simplifying the repair process.
What happens if I don’t replace a failing TCM?
Ignoring a failing TCM can lead to more severe and costly damage. Continued erratic shifting can cause excessive wear on clutches, bands, and other internal transmission components, potentially leading to a complete transmission failure that requires a full rebuild or replacement.
