If your 2006-2007 Buick Rendezvous is suffering from unpredictable shifting, getting stuck in gear, or has the check engine light on with transmission codes, you’ve come to the right place. As a technician with over two decades of experience, I’ve seen firsthand how a failing Transmission Control Module (TCM) can mimic a catastrophic transmission failure, leading to stress and unnecessary repair quotes. This T42 TCM, part number 24243901, is the precise, reliable solution to restore your vehicle’s performance and your peace of mind.
The TCM is the electronic brain of your automatic transmission. It processes data from various sensors to command precise gear shifts, manage torque converter clutch lockup for optimal fuel economy, and monitor the overall health of the system. Over time, heat cycles and vibrations can cause internal electronic components to fail, leading to the frustrating symptoms you’re likely experiencing. This isn’t just an inconvenience; it can be a safety issue when your vehicle doesn’t respond as expected in traffic.
Case Study: A Tricky Diagnosis
A customer brought in their ’07 Rendezvous with classic symptoms: harsh 1-2 shifts and occasionally getting stuck in 3rd gear (limp mode), with a generic P0700 code stored. They were worried they needed a full transmission rebuild, a quote they’d received for over $3,000. After checking the fluid and running a full diagnostic, I noticed intermittent communication loss with the TCM. We swapped in a pre-programmed module like this one. The total repair time was under an hour, and the vehicle shifted perfectly. The problem was never mechanical; it was the failing electronics inside the original 2006-2007 Rendezvous TCM. This part saved them thousands.
Is Your Buick Rendezvous Showing These Telltale Signs?
A faulty TCM can manifest in several ways. If you’re noticing any of the following, it’s a strong indicator that your module needs replacement:
- ✔ Harsh, slamming, or delayed gear shifts.
- ✔ The vehicle is stuck in a single gear, often referred to as “limp mode.”
- ✔ Your Check Engine Light or a dedicated transmission warning light is illuminated.
- ✔ Diagnostic trouble codes (DTCs) like P0700, P0750, or other solenoid-related faults are present.
- ✔ A noticeable drop in fuel efficiency due to improper gear selection or torque converter function.
- ✔ Complete loss of communication with the TCM, preventing shifting altogether.
Your 30-Minute Path to a Smooth Ride
One of the biggest advantages of this module is the simple, DIY-friendly installation. Because we pre-program it to your vehicle’s VIN, you can skip the expensive trip to the dealership. For the 2006-2007 Buick Rendezvous, the TCM is conveniently located under the air cleaner box.
- Safety First: Always disconnect the negative terminal from your vehicle’s battery before starting any electronic work.
- Locate the Module: Open the hood and find the air cleaner assembly. You will need to remove it to access the TCM mounted below it.
- Disconnect and Remove: Carefully unplug the electrical connectors from the old TCM. Then, unbolt the module from its mounting bracket.
- Install the New TCM: Mount the new module in place, securely tightening the bolts. Reconnect the electrical harnesses, ensuring they click into place.
- Reassemble and Finalize: Reinstall the air cleaner box. Reconnect the battery terminal. Start the vehicle and take it for a test drive to confirm the shifting issues are resolved. Any stored codes should clear, but using a basic scan tool to erase them is always good practice.

Frequently Asked Questions
Do I need to have this module programmed by a dealer?
No. We pre-program the module to your vehicle’s specific VIN before shipping. This makes it a true plug-and-play solution, saving you time and money.
Is this a difficult part to install myself?
For most DIY enthusiasts with basic tools, this is a very manageable job. On the 2006-2007 Rendezvous, it’s located under the air cleaner box and can typically be swapped in under an hour.
What is a core charge?
A core charge is a deposit you pay until you return your old part. We do not have a core charge on this item, so you can keep your old module without any hassle.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code, meaning the TCM has detected a problem and requested the check engine light. While a faulty TCM can cause a P0700, this module is designed to resolve the underlying electronic issues that often trigger it and other specific transmission codes.
What kind of warranty is included?
This module comes with a one-year replacement warranty, giving you confidence in the quality and durability of your repair.
