Is Your 2006-2007 Buick Rendezvous Shifting Erratically?
A faulty Transmission Control Module (TCM) can turn your daily drive into a frustrating and unpredictable experience. If you’re dealing with harsh gear changes, getting stuck in limp mode, or seeing a persistent check engine light, you’re not alone. The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every shift with precision. When it fails, the communication between your engine and transmission breaks down, leading to poor performance, decreased fuel economy, and potential damage to other driveline components. This VIN-programmed T42 TCM is the definitive solution to restore your vehicle’s original shifting performance and reliability.
From the Diagnostic Bay
We recently had a 2007 Rendezvous come in with classic symptoms of a failing transmission—delayed engagement into drive and harsh, slamming shifts between 1st and 2nd gear. The owner had already spent a few hundred dollars at another shop replacing shift solenoids, but the problem persisted. A quick scan showed a P0700 code (Transmission Control System Malfunction). Instead of guessing, we tested the circuits between the TCM and the transmission. The wiring was fine, pointing directly to an internal failure in the original module. After installing one of our pre-programmed TCMs, the vehicle shifted as smoothly as it did the day it left the factory. The customer was thrilled to have a real fix without the guesswork and extra cost of unnecessary parts.
Symptoms of a Failing Rendezvous TCM
- ✔ Harsh, erratic, or delayed gear shifting.
- ✔ Vehicle is stuck in one gear (limp mode), often 2nd or 3rd.
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- ✔ Complete loss of upshifting or downshifting capabilities.
- ✔ A noticeable decrease in fuel efficiency.
- ✔ Intermittent electrical problems related to transmission function.

Frequently Asked Questions
Do I need to program this module?
No. We pre-program the module to your vehicle’s VIN before shipping. It will arrive ready for installation, requiring no further programming or trips to the dealership.
Where is the TCM located on a 2006-2007 Buick Rendezvous?
On the 2006-2007 Rendezvous, the transmission control module is typically located inside or under the air cleaner box in the engine compartment, making it reasonably accessible for replacement.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating that the TCM has detected a problem and has requested the check engine light be turned on. While a faulty TCM is a very common cause, this code can also be triggered by other transmission issues. Replacing a known-bad TCM is the correct fix for the module itself causing the code.
Is this a difficult part to install?
For someone with basic mechanical skills, the installation is straightforward and typically takes less than 30 minutes. The process involves disconnecting the battery, unplugging the electrical connectors, removing the mounting bolts, and swapping the module. Always ensure the battery is disconnected before starting.
