Is Your Buick Rendezvous Struggling with Shifting?
As a mechanic with two decades of experience under the hood, I’ve seen countless drivers frustrated by transmission issues. If your 2006-2007 Buick Rendezvous is experiencing harsh shifts, getting stuck in gear, or throwing transmission-related codes, the problem is often the Transmission Control Module (TCM). This small electronic unit is the brain of your automatic transmission, and when it fails, it can make your reliable SUV feel unpredictable and unsafe. You’re not just buying a part; you’re restoring your vehicle’s smooth operation and your peace of mind.
This isn’t just another part off the shelf. We offer a direct-fit solution with this OEM-quality T42 TCM, specifically for your vehicle. The biggest hurdle with electronic modules is the need for expensive dealership programming. We eliminate that step entirely. By providing your vehicle’s VIN at checkout, we program the module with the latest GM software before it even ships. This ensures it communicates perfectly with your Rendezvous’s engine computer and other systems right out of the box. This is the definitive fix for a faulty 2006-2007 Rendezvous TCM, designed to get you back on the road without the dealership hassle.
Case Study: A Tricky Diagnosis
A customer brought in a 2007 Rendezvous with a classic complaint: it would randomly refuse to shift out of 2nd gear, and the check engine light was on. They had already replaced a shift solenoid based on a code, but the problem persisted. After hooking up my pro-level scan tool, I saw the solenoid codes were intermittent, but I also noticed erratic voltage readings from the TCM itself. Heat soak from the engine compartment had caused an internal failure in the module’s circuit board. We installed a VIN-programmed TCM, cleared the codes, and the vehicle drove perfectly. It’s a textbook example of how a failing 2006-2007 Rendezvous TCM can mimic other transmission problems, making a correct diagnosis key.
Is Your Rendezvous Showing These Telltale Signs?
- ✔ Harsh, clunky, or erratic gear changes that disrupt your drive.
- ✔ The vehicle feels stuck in one gear (often called “limp mode”).
- ✔ Check Engine Light is on with Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other transmission solenoid codes.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ A noticeable drop in fuel economy due to inefficient shifting.
- ✔ Complete failure to shift, leaving you stranded.
DIY-Friendly Installation Guide for Your Rendezvous
Replacing the TCM on your Buick Rendezvous is a straightforward job that most DIYers can handle in their driveway in under 30 minutes. The module is conveniently located for easy access.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the onboard systems.
- Locate the Module: On the 2006-2007 Rendezvous, you will find the TCM located under the air cleaner box in the engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old TCM. Then, unbolt the module from its mounting bracket.
- Install the New Module: Bolt the new, pre-programmed TCM into place and securely reconnect the electrical harnesses. Ensure they click into place.
- Final Steps: Reconnect the battery terminal. Start the vehicle and let it idle for a few minutes. While the module is plug-and-play, it’s always a good practice to use a basic scan tool to clear any stored fault codes from the computer’s memory.

Frequently Asked Questions
Does this module really not require a trip to the dealer?
That’s correct. We pre-program the module to your vehicle’s specific VIN before shipping. This makes the installation plug-and-play, saving you the time and expense of a dealership programming fee.
Is there a core charge for my old part?
No, there is no core charge. You can keep your old module or dispose of it without the hassle of returning it to us.
What tools do I need for the installation?
You will only need basic hand tools, such as a socket set and a wrench, to disconnect the battery and unbolt the module. No special diagnostic equipment is required for the installation itself.
What if I still have a check engine light after installation?
The module is programmed to resolve the faults. However, the vehicle’s computer may retain old “historical” codes. These can be easily cleared by disconnecting the battery for 15 minutes or using any standard OBD2 code reader.
How do I provide my VIN for programming?
You will be prompted to enter your vehicle’s 17-digit VIN during the checkout process. Please double-check it for accuracy to ensure perfect programming.
