Restore Smooth, Reliable Shifting to Your Buick Rendezvous
If your 2006-2007 Buick Rendezvous is suffering from harsh shifting, getting stuck in gear, or throwing transmission codes, a failing Transmission Control Module (TCM) is the most likely culprit. As the electronic brain of your automatic transmission, the TCM dictates every gear change. When it fails, drivability suffers. This OEM-quality T42 TCM, part number 24241806, is the definitive solution. It arrives pre-programmed to your vehicle’s specific VIN, eliminating the need for expensive dealership visits and ensuring a true plug-and-play repair.
From the Diagnostic Bay
I remember a customer bringing in a 2007 Rendezvous with a classic complaint: “It slams into gear and sometimes won’t shift past second.” The check engine light was on, and a quick scan revealed a P0700 (Transmission Control System Malfunction) code. After confirming power and ground at the TCM connector, the diagnosis was clear. These T42 modules, especially after years of heat cycles under the hood, are prone to internal circuit failure. We installed one of our VIN-programmed units, cleared the codes, and the vehicle shifted like it just left the factory. This part directly addresses that common point of failure, saving you diagnostic headaches and repair costs.
Is Your Buick Showing These Telltale Signs?
A faulty module can cause a range of frustrating issues. If you’re experiencing any of the following, our 2006-2007 Rendezvous TCM is the solution you need.
- ✔ Harsh, erratic, or delayed gear shifts.
- ✔ Vehicle stuck in “limp mode” (usually 2nd or 3rd gear).
- ✔ Check Engine Light or Transmission Warning Light is illuminated.
- ✔ Diagnostic Trouble Codes (DTCs) like P0700, P0750, or other solenoid-related faults.
- ✔ A sudden drop in fuel economy.
- ✔ Complete loss of communication with the TCM, preventing shifting.
DIY-Friendly Installation in Under 30 Minutes
Replacing the TCM on your Rendezvous is a straightforward job that most DIYers can handle with basic tools. The module is conveniently located for easy access.
- Safety First: Disconnect the negative terminal from your vehicle’s battery to prevent any electrical shorts.
- Locate the Module: On the 2006-2007 Rendezvous, you’ll find the TCM located inside or attached to the air cleaner box in the engine compartment.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old module. Then, unbolt the module from its mounting bracket.
- Install the New Module: Mount the new, pre-programmed TCM in place, re-secure the bolts, and firmly plug in the electrical connectors until they click.
- Final Steps: Reconnect the battery terminal. While the module is plug-and-play, it’s always a good practice to use a scan tool to clear any stored fault codes from the vehicle’s memory.
