Is Your 2006-2007 Buick Rendezvous Shifting Erratically?
If your Buick Rendezvous is suffering from harsh shifting, delayed gear engagement, or has suddenly entered 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 coordinating every shift, managing torque converter lockup, and monitoring system health. When it fails, it can cause a cascade of frustrating and potentially damaging issues, from poor fuel economy to a complete inability to shift gears. This replacement GM T42 TCM, part number YNXS, is the definitive solution to restore your vehicle’s factory performance and drivability.
From the Diagnostic Bay
We once had a 2007 Rendezvous come in with classic transmission failure symptoms: banging into gear and a P0700 code. The owner had already spent a small fortune replacing shift solenoids with no success. After a quick scan, we confirmed communication with the TCM was intermittent. The internal logic board had failed. We installed one of our VIN-programmed T42 modules, cleared the codes, and the vehicle shifted like it just rolled off the assembly line. It’s a powerful reminder that diagnosing the root cause—often the module itself—saves time, money, and headaches.
The Plug-and-Play Advantage: VIN Programming Included
Don’t get stuck with a generic module that requires an expensive trip to the dealership for programming. Our modules are meticulously programmed to your vehicle’s specific Vehicle Identification Number (VIN) before they ship. This critical step ensures that the TCM has the latest GM software and is perfectly calibrated for your Rendezvous’s unique configuration. The result is a simple, plug-and-play installation that you can perform in your own driveway. By matching the module to your VIN, we eliminate compatibility issues and common diagnostic trouble codes (DTCs) right out of the box.

Frequently Asked Questions
What does ‘VIN Programmed’ actually mean?
It means we load your vehicle’s unique 17-digit Vehicle Identification Number (VIN) and the latest GM-certified software onto the module before shipping. This ensures the TCM works perfectly with your vehicle’s specific engine, transmission, and options, eliminating the need for any additional programming at a dealership.
Do I need any special tools for installation?
No special tools are required. Basic hand tools like a socket set are all that’s needed to access and replace the module. We do recommend disconnecting the battery before starting and using a basic OBD2 scan tool to clear any stored fault codes after the new module is installed.
Where is the TCM located on my 2006-2007 Buick Rendezvous?
On the 2006-2007 Rendezvous, the transmission control module is located under the air cleaner box in the engine compartment. This makes it relatively easy to access for replacement.
Will this module fix a P0700 trouble code?
A P0700 code is a general transmission fault request, meaning the TCM has detected a problem and asked the main engine computer (ECU) to turn on the check engine light. While this module often resolves the underlying issue causing the P0700, it’s crucial to scan for other specific transmission codes (e.g., P07xx) to confirm the TCM is the root cause.
Is there a core charge for my old part?
No, there is no core charge required for this module. You can keep your old part without any hassle or need to return it, simplifying the repair process for you.
