Is Your 2006-2007 Buick Rendezvous Shifting Erratically?
If your Buick Rendezvous is experiencing harsh shifting, delayed gear engagement, or is stuck in limp mode, a failing Transmission Control Module (TCM) is the most likely culprit. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every shift with precision. When it fails, it can mimic the symptoms of a catastrophic mechanical failure, leading to confusion and potentially expensive misdiagnoses. This replacement T42 TCM, part number 24255280, is the definitive solution to restore your vehicle’s performance and drivability.
From the Diagnostic Bay
We recently had a 2007 Rendezvous towed to our shop. The owner was convinced the transmission was completely gone, as it would slam into gear and refuse to shift beyond second. Another shop had already quoted them over $3,000 for a transmission rebuild. Our first step was to scan for codes, which revealed several communication errors pointing directly to the TCM. Instead of a costly rebuild, we installed a VIN-programmed module just like this one. In under 30 minutes, the vehicle was back on the road, shifting as smoothly as the day it left the factory. Always check the electronics first—it can save you thousands.
Why Choose Our Programmed Rendezvous Transmission Module?
The biggest hurdle in replacing a modern vehicle module is the need for expensive dealership programming. Our Rendezvous Transmission Module eliminates this step entirely. We pre-program each unit to your vehicle’s specific Vehicle Identification Number (VIN) before it ships. This ensures that the module communicates flawlessly with your vehicle’s other systems, like the Engine Control Module (ECM) and Body Control Module (BCM), right out of the box. You get a plug-and-play part that restores original performance without any additional costs or hassle.
Symptoms of a Failing 2006-2007 Rendezvous TCM
- ✔ Erratic and Harsh Shifting: Experiencing sudden, jerky shifts or a noticeable slam when the transmission changes gears.
- ✔ Stuck in Gear / Limp Mode: The vehicle may refuse to shift out of a single gear (often 2nd or 3rd) to prevent further damage.
- ✔ Warning Lights: The Check Engine Light or a specific transmission warning light will illuminate on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): Common codes associated with a failing TCM include P0700 (Transmission Control System Malfunction) and various solenoid-specific codes (e.g., P0750, P0753).
- ✔ Delayed Engagement: A noticeable pause after shifting from Park to Drive or Reverse before the gear engages.
- ✔ Poor Fuel Economy: Inefficient shifting patterns caused by the faulty module can lead to a significant drop in gas mileage.

Frequently Asked Questions
What does a Transmission Control Module do on a Buick Rendezvous?
The TCM acts as the central computer for your automatic transmission. It collects data from various sensors (like vehicle speed and engine RPM) to determine the perfect moment to shift gears, control the torque converter lockup, and manage fluid pressure for smooth and efficient operation.
Is this TCM difficult to install?
No, it’s a relatively simple installation for a DIY mechanic. On the 2006-2007 Rendezvous, it’s located in the air cleaner box. The process involves disconnecting the battery, removing the air box, and swapping the modules. No special tools are required.
Do I need to take my vehicle to a dealer after installing this part?
Absolutely not. This module comes pre-programmed to your vehicle’s VIN. This plug-and-play solution means you can avoid the time and expense of a dealership visit for programming.
How do I know if my TCM is failing and not the transmission itself?
While symptoms can overlap, TCM failure is often electronic in nature. Look for specific transmission-related error codes (like P0700), intermittent problems that seem to resolve after restarting the car, or shifting issues without any unusual mechanical noises like grinding or whining from the transmission itself.
What happens if I don’t provide my VIN when ordering?
Providing your VIN is critical for the pre-programming process. Without it, we cannot program the module to match your vehicle’s specific configuration, and it will not function correctly. Please be sure to enter your VIN during checkout to ensure a successful repair.
Will this module fix specific error codes like P0700?
Yes. If the error codes, such as P0700 or various solenoid circuit codes, are being caused by a faulty internal TCM processor or driver, this replacement module is the correct fix. It is designed to resolve these common electronic faults.
