Restore Peak Transmission Performance to Your Buick Rendezvous
Is your 2006-2007 Buick Rendezvous suffering from erratic shifting, getting stuck in gear, or showing transmission-related warning lights? These are classic signs of a failing Transmission Control Module (TCM). The TCM is the electronic brain of your automatic transmission, responsible for orchestrating smooth gear changes, managing torque converter lockup, and ensuring overall driveline efficiency. When it fails, the driving experience can become unpredictable and frustrating. This replacement GM T42 TCM, service number 24235732, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We recently had a 2007 Rendezvous come into the shop with the check engine light on and a complaint of harsh, banging shifts, especially from first to second gear. The owner had already replaced two shift solenoids based on a generic code reader’s output, but the problem persisted. Our professional scan tool revealed a P0700 (Transmission Control System Malfunction) code, but more importantly, we saw intermittent communication loss with the TCM itself. Instead of throwing more parts at it, we identified the root cause: a failing TCM. After installing one of our VIN-programmed modules, the communication was stable, all codes were cleared, and the vehicle shifted as smoothly as it did the day it left the factory. This case highlights how correctly diagnosing the TCM can save you time, money, and unnecessary repairs.
Diagnosing a Faulty 2006-2007 Rendezvous TCM
A failing TCM can manifest in various ways, often mimicking other transmission problems. If you’re experiencing any of the issues below, your transmission control module is the likely culprit. This module is engineered to directly address these common failure points and restore proper function without the need for a trip to the dealership for programming.
Common Symptoms of TCM Failure
- ✔ Harsh or erratic gear shifting that feels like the transmission is banging into gear.
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Vehicle entering “limp mode,” often stuck in 2nd or 3rd gear to prevent further damage.
- ✔ Illumination of the Check Engine Light or other transmission warning indicators on your dash.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-specific codes.
- ✔ A noticeable decrease in fuel economy due to inefficient shifting patterns.
- ✔ Complete failure to shift up or down, or intermittent loss of gear control.

Frequently Asked Questions
What does this TCM do for my 2006-2007 Rendezvous?
The Transmission Control Module (TCM) acts as the computer for your automatic transmission. It processes data from various sensors to control shift points, line pressure, and torque converter lockup, ensuring your Rendezvous drives smoothly and efficiently.
Is this part truly plug-and-play?
Yes. We pre-program the module to your vehicle’s specific VIN before shipping. This means it’s ready for installation right out of the box, with no additional dealership programming or calibration required.
Where is the TCM located on a 2006-2007 Buick Rendezvous?
On this specific model, the TCM is conveniently located inside the air cleaner box in the engine compartment. This makes it relatively easy to access and replace with basic hand tools.
Will this 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 of a P0700, it’s essential to ensure there aren’t other underlying issues. However, if you’re experiencing shifting problems along with the code, a faulty TCM is the most probable cause.
Do I need to send my old module back?
No, there is no core charge for this part. You can keep your old module, eliminating the hassle and expense of return shipping.
