Restore Flawless Shifting to Your Buick Rendezvous
Is your 2006-2007 Buick Rendezvous suffering from harsh shifting, delayed gear engagement, or a persistent check engine light? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating every gear change and ensuring smooth, efficient operation. When it fails, it can lead to poor performance, decreased fuel economy, and even leave you stranded. This genuine GM T42 Transmission Control Module, service part number 24234503, is the definitive solution to restore your vehicle’s drivability and peace of mind.
From the Diagnostic Bay
We had a 2007 Rendezvous come into the shop that was driving the owner crazy. It had a brutal 1-2 shift that would jerk the whole vehicle, and occasionally it would get stuck in 3rd gear (limp mode). The owner had already spent money replacing a couple of shift solenoids, but the problem persisted. A quick scan showed a P0700 (Transmission Control System Malfunction) code. We knew right away the issue was likely electronic, not mechanical. Instead of more guesswork, we installed one of our VIN-programmed T42 modules. The moment we started the car and went for a test drive, the difference was night and day. Every shift was smooth and perfectly timed. The customer was thrilled to have their reliable SUV back without an expensive trip to the dealership for programming.
Common Symptoms of a Failing Rendezvous Transmission Module

Frequently Asked Questions
What is VIN programming and why is it required?
VIN programming loads your vehicle’s specific software and calibration files onto the Transmission Control Module. This is critical for the TCM to communicate correctly with your Rendezvous’s engine and other systems. Our pre-programming service saves you a trip to the dealership and ensures the part works perfectly right out of the box.
Where is the TCM located on a 2006-2007 Buick Rendezvous?
On the 2006-2007 Buick Rendezvous, the Transmission Control Module is typically located inside or attached to 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 fault code indicating the TCM has detected a problem. While this module often resolves the root cause that triggers a P0700, it’s essential to diagnose any other codes that may be present. In many cases where the TCM itself is faulty, replacing it will clear this code and related transmission faults.
Do I need any special tools for this installation?
Basic hand tools like a socket set and screwdriver are typically all that’s needed to access and replace the module. After installation, it is recommended to use a standard OBD2 scan tool to clear any stored trouble codes from the vehicle’s memory.
Is there a warranty included with this part?
Yes, this Transmission Control Module comes with a one-year warranty, giving you confidence and peace of mind in your repair.
