Restore Flawless Shifting to Your 2006-2007 Buick Rendezvous
If your 2006-2007 Buick Rendezvous is suffering from harsh shifting, delayed gear engagement, or has a check engine light with transmission-related codes, a failing Transmission Control Module (TCM) is the most likely culprit. This critical component is the brain of your automatic transmission, responsible for managing every shift, controlling torque converter lockup, and ensuring smooth, efficient operation. When it fails, it can make your vehicle unreliable and frustrating to drive. This replacement GM T42 TCM, part number 24234274, is the definitive solution, pre-programmed to your vehicle’s specific VIN for a true plug-and-play installation.
From the Diagnostic Bay
We had a 2007 Rendezvous come into the shop with classic symptoms of a failing transmission—slipping between gears and a P0700 code. The owner was convinced they needed a complete transmission rebuild, a costly and time-consuming job. However, after running diagnostics, we noticed the solenoid command signals were erratic. Instead of jumping to the most expensive conclusion, we swapped in a VIN-programmed TCM first. The vehicle immediately started shifting perfectly. The issue wasn’t a mechanical failure inside the transmission but an electronic failure in the module telling it what to do. This simple part saved the customer thousands of dollars and got their SUV back on the road the same day.
Is Your Rendezvous Exhibiting These TCM Failure Symptoms?
A faulty TCM can manifest in several ways, often mimicking more severe mechanical transmission problems. Before considering a costly transmission replacement, check if you’re experiencing any of the following common signs of a bad 2006-2007 Rendezvous TCM.
- ✔ Harsh, jerky, or erratic gear shifts.
- ✔ The vehicle gets stuck in one gear (often called “limp mode”).
- ✔ Delayed engagement when shifting from Park to Drive or Reverse.
- ✔ Transmission or Check Engine warning lights are illuminated on the dash.
- ✔ Diagnostic trouble codes (DTCs) such as P0700, P0750, or other solenoid-related faults are present.
- ✔ A noticeable decrease in fuel economy.
- ✔ The transmission seems to slip out of gear or fails to upshift or downshift correctly.

Frequently Asked Questions About the 2006-2007 Rendezvous TCM
What does a Transmission Control Module do in my Buick Rendezvous?
The TCM acts as the central computer for your automatic transmission. It collects data from various sensors on the engine and transmission to determine the perfect moment to shift gears, control fluid pressure, and engage the torque converter clutch for maximum efficiency and smoothness.
Why is VIN programming so important for this part?
VIN programming loads your vehicle’s specific software and settings onto the module. Without it, a new TCM won’t be able to communicate correctly with your vehicle’s other computers, leading to continued shifting problems or the vehicle not starting at all. Our pre-programming service eliminates the need for expensive dealership tools and labor.
Can I install this TCM myself?
Absolutely. For a 2006-2007 Rendezvous, the TCM is located in the air cleaner box. The replacement process is simple and typically takes less than 30 minutes with basic tools. Just remember to disconnect the battery before you begin.
Will this part fix my P0700 trouble code?
A P0700 code is a general transmission fault code, indicating that the TCM has detected a problem. In many cases, a faulty TCM is the root cause. Replacing the module with this pre-programmed unit will often resolve the P0700 code and any related solenoid codes.
Is there a core charge for this part?
No, there is no core charge. You are not required to send your old, faulty module back to us, saving you time and money on return shipping.
