Restore Your Buick’s Shifting Performance

If your 2006-2007 Buick Rendezvous is suffering from jerky shifting, getting stuck in gear, or has an illuminated check engine light, a failing Transmission Control Module (TCM) is the most likely culprit. As a technician with over two decades of diagnostic experience, I’ve seen countless GM vehicles sidelined by these exact issues. This T42 TCM, part number 24238856, is the definitive solution to get your vehicle driving smoothly and reliably again. It arrives expertly programmed to your vehicle’s specific VIN, eliminating the need for an expensive and time-consuming trip to the dealership. This is a true plug-and-play fix designed for both professional installers and DIY enthusiasts.

A Technician’s Notebook: The Rendezvous Stuck in Limp Mode

A customer brought in a 2007 Rendezvous that wouldn’t shift out of 3rd gear—a classic case of ‘limp mode.’ The dash was lit up with a Check Engine light, and my scan tool pulled a P0700 (Transmission Control System Malfunction) code. These T42 modules, often located under the air cleaner box, are susceptible to failure from years of engine heat and vibration. Instead of a costly transmission rebuild, the fix was this pre-programmed module. In under 30 minutes, the new TCM was in, the codes were cleared, and the Rendezvous was shifting perfectly. It’s a common, straightforward repair that restores the vehicle’s drivability completely.

Is Your Rendezvous Exhibiting These Telltale Signs?

A faulty TCM can manifest in several ways. If you’re experiencing any of the following, it’s time to consider a replacement. Ignoring these symptoms can lead to more significant transmission damage and reduced vehicle safety.

  • ✔ Harsh, slamming shifts or delayed gear engagement.
  • ✔ Vehicle is stuck in one gear (often 2nd or 3rd) and will not upshift or downshift.
  • ✔ Check Engine Light or Transmission Warning Light is on with codes like P0700, P0751, P0756, etc.
  • ✔ A sudden drop in fuel economy as the transmission operates inefficiently.
  • ✔ Complete loss of communication with the module, preventing the vehicle from starting or shifting out of Park.

DIY-Friendly Installation Guide for Your Rendezvous

Replacing the 2006-2007 Rendezvous TCM is a job most people can handle with basic tools. The key is our VIN programming, which makes it a simple swap. For the Rendezvous, you’ll find the module conveniently located under the air cleaner box.

  1. Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts and to help reset the system.
  2. Locate the Module: On your Rendezvous, remove the air cleaner assembly to gain access to the TCM mounted below it.
  3. Disconnect and Remove: Carefully unplug the electrical connectors. Press the release tabs firmly. Then, unbolt the old module from its mounting bracket.
  4. Install the New TCM: Mount the new module in the same location, securely fastening the bolts. Reconnect the electrical harnesses, ensuring they click into place.
  5. Final Steps: Reinstall the air cleaner assembly and reconnect the battery terminal. Start the vehicle to confirm it shifts correctly. It’s a good practice to use a basic scan tool to clear any stored fault codes after installation.
