Restore Dependable Shifting to Your Workhorse Van
When your 2006-2014 GMC Savana 1500’s transmission starts acting up, your entire workday can grind to a halt. Unpredictable shifting, warning lights, or a van stuck in limp mode aren’t just frustrating—they cost you time and money. Get your vehicle back to being the reliable partner you depend on with this pre-programmed T42 Transmission Control Module (TCM). It’s designed to be a direct, plug-and-play solution that restores the crisp, smooth shifting you expect, without a mandatory trip to the dealership.
Common Symptoms & Your Solution
A failing TCM can cause a wide range of issues that can be easily mistaken for major mechanical failure. If your Savana is experiencing any of the following, this module is the definitive solution:
- Harsh or Erratic Shifting: Abrupt, jerky gear changes or a delay in engagement when shifting from park to drive or reverse.
- Stuck in Gear / Limp Mode: The transmission refuses to shift, often getting stuck in 2nd or 3rd gear to prevent further damage.
- Warning Lights: An illuminated Check Engine Light or transmission warning light on your dash, often with diagnostic trouble codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- Poor Performance: A noticeable drop in fuel economy, failure to upshift or downshift correctly, and potential transmission overheating.
Installing our Programmed Savana 1500 Transmission Control Module directly addresses the root electronic cause of these problems, restoring communication and precise control over your transmission’s functions.

Expert Insight: The Critical Role of VIN Programming
In modern vehicles like your Savana, the TCM isn’t just a simple switch; it’s a computer that constantly communicates with the Engine Control Module (ECM) and other vehicle systems. A generic, non-programmed module simply won’t work. Our VIN programming service uploads your van’s unique software and the latest GM updates directly to the unit before it ships. This ensures that the TCM understands your specific engine, axle ratio, and tire size, allowing for flawless communication and optimal transmission performance from the moment you install it.
Don’t let a faulty electronic part sideline your vehicle. This Programmed Savana 1500 Transmission Control Module is the most efficient and reliable way to get your van back on the road and working for you. Compatible with service numbers 24242391, 24234503, 24252114, and more, it’s the right part for a lasting repair.
Frequently Asked Questions
Do I need to take my van to a dealer after installation?
No. The primary benefit of this module is that it comes pre-programmed to your vehicle’s VIN. This eliminates the need for any additional programming or setup at a dealership, making it a true plug-and-play installation.
Is this TCM difficult to install?
For someone with basic mechanical skills, installation is straightforward. On most Savana vans, the TCM is located in the engine compartment on the right-hand side. The process typically involves disconnecting the battery, unplugging the electrical connectors, unbolting the old module, and installing the new one. It can often be completed in under 30 minutes.
How do I know for sure if my TCM is failing?
Common signs include erratic shifting, getting stuck in one gear (limp mode), and specific transmission-related diagnostic trouble codes (like P0700). While other issues can cause similar symptoms, if you’re experiencing these electronic-type failures, the TCM is a very likely culprit.
Will this part fix transmission error code P0700?
P0700 is a general fault code indicating that the TCM has detected a problem and has requested the Check Engine Light be turned on. This module often resolves the underlying issue that causes the P0700 code, but it’s essential to scan for other, more specific codes (e.g., solenoid codes) to confirm the diagnosis.
Is a core charge required for this part?
No, there is no core charge for this transmission control module. You can keep your old part without any hassle or need to return it.
