Restore Peak Transmission Performance in Your GMC Savana

If your 2006-2014 GMC Savana 1500 is suffering from erratic shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for managing shift points, torque converter lockup, and line pressure. When it fails, it can cause a wide range of drivability issues that can sideline your vehicle. This OEM-quality T42 TCM, part number 24241806, is the definitive solution, arriving pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.

From the Diagnostic Bay

We recently had a 2011 Savana 2500 work van come into the shop that was perpetually stuck in 3rd gear—a classic limp mode symptom. The owner had already spent money replacing two shift solenoids based on the trouble codes, but the problem didn’t go away. A quick check with our diagnostic tools showed the command signal from the TCM to the solenoids was inconsistent. The internal TCM processor was failing under load. We installed one of our VIN-programmed T42 modules, cleared the codes, and the van was shifting perfectly within 20 minutes. It’s a textbook example where chasing codes can be misleading; the root cause was the controller itself.

Is Your Savana Exhibiting These Transmission Problems?

A faulty TCM can manifest in several ways. Look for these common indicators that it’s time for a replacement:

  • ✔ Harsh, erratic, or delayed gear changes that make driving unpredictable and uncomfortable.
  • ✔ The vehicle is stuck in a single gear (often 2nd or 3rd), a protective state known as “limp mode.”
  • ✔ The Check Engine Light or a dedicated Transmission Warning Light is illuminated on your dashboard.
  • ✔ Stored Diagnostic Trouble Codes (DTCs) such as P0700 (Transmission Control System Malfunction), P0750, or other solenoid-related faults.
  • ✔ A noticeable hesitation or clunk when shifting from Park into Drive or Reverse.
  • ✔ A significant decrease in fuel economy due to the transmission operating inefficiently.
  • ✔ Complete loss of communication with the transmission, leading to a no-shift condition.

The Right Fix: Your 2006-2014 Savana 1500 Transmission Module

Don’t settle for a generic, unprogrammed module that requires an expensive trip to the dealership. This T42 TCM is the smart, efficient solution. The most critical feature is our VIN programming service. We load the latest GM-certified software directly onto the module using your vehicle’s unique VIN. This ensures that all shift parameters and communication protocols are perfectly matched to your Savana 1500’s specific configuration. The result is restored factory performance, smoother shifting, and improved fuel efficiency right out of the box.

This module is built to meet or exceed original equipment standards, ensuring long-lasting reliability for your work van or personal vehicle. It directly replaces a wide range of original part numbers, including 24252114, 24234503, and 24241806, making it a versatile and dependable choice for a variety of GM trucks, vans, and SUVs equipped with 4-speed automatic transmissions like the 4L60E, 4L65E, and 4L70E.

Simple Installation to Get You Back on the Road

Installation is straightforward for anyone with basic automotive experience. On the GMC Savana, the TCM is typically located in the engine compartment on the right-hand side. The process generally takes less than 30 minutes.

  1. Disconnect the Battery: Always disconnect the negative battery terminal before working on vehicle electronics to prevent damage and help reset the system.
  2. Locate and Remove the Old TCM: Unplug the electrical connectors and unbolt the old module from its mounting bracket.
  3. Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses.
  4. Reconnect Battery & Clear Codes: Reconnect the battery. While the new module is plug-and-play, it’s best practice to use a standard OBD2 scan tool to clear any lingering fault codes from the vehicle’s memory.

Best of all, there is no core charge. You don’t have to worry about the cost or hassle of sending your old, faulty part back.

Frequently Asked Questions

What does “VIN Programmed” actually mean?

VIN programming means we load your vehicle’s specific factory software and calibrations onto the module before we ship it. This ensures it communicates perfectly with your engine computer and other systems, eliminating the need for additional programming at a dealership. It’s a true plug-and-play solution.

Is this a difficult part to install myself?

For most DIYers with basic tools, this is a relatively simple installation. The module is easily accessible in the engine bay on most vehicles, including the Savana van. The process involves disconnecting the battery, unplugging a few connectors, and removing a few bolts. No complex procedures are required.

Will this module fix a P0700 trouble code?

A P0700 code is a general fault code indicating that the TCM has detected a problem within the transmission system. While a failing TCM is a very common cause of this code, it’s essential to confirm the diagnosis. This module is designed to resolve the internal electronic failures that frequently trigger a P0700 and related solenoid codes.

Do I need to send my old module back?

No. We do not require you to return your old part. This product comes with no core charge, saving you time and money.

How can I be sure this part fits my vehicle?

This module fits a wide range of 2006-2014 GM vehicles. The best way to confirm fitment is to match your vehicle’s year, make, and model to the provided compatibility list. You can also match the service number on your existing module to the numbers listed, such as 24241806, 24252114, or 24234503.
