Restore Smooth Shifting to Your Buick Rendezvous
If you’re dealing with the frustration of a 2006-2007 Buick Rendezvous that shifts harshly, gets stuck in gear, or has an illuminated check engine light, you’re not alone. The Transmission Control Module (TCM), the electronic brain of your automatic transmission, is a common point of failure. This VIN-programmed T42 TCM, compatible with part number YNXS, is the reliable, straightforward solution to get your vehicle driving like new again, eliminating the need for an expensive trip to the dealership.
Case Study: A Tricky Diagnosis
I remember a 2007 Rendezvous that came into my shop a few years back. The owner was frustrated; he’d been told he might need a full transmission rebuild. The vehicle would intermittently refuse to shift out of 2nd gear (classic limp mode) and had a generic P0700 transmission fault code. After checking the fluid and wiring, my diagnostic process led me to the TCM. Heat and vibration, especially with its location under the air cleaner box, had taken a toll on the internal circuits. We swapped in a VIN-programmed module just like this one, and in less than an hour, the Rendezvous was shifting perfectly. It’s a prime example of how the right part can save a customer thousands in unnecessary repairs.
Is Your Rendezvous Showing These Transmission Warning Signs?
A failing TCM can cause a range of symptoms that are often misdiagnosed. If you’re experiencing any of the following, this module is likely the solution you need.
- âś” Harsh, jerky, or delayed gear shifts.
- âś” The vehicle is stuck in “limp mode” and won’t shift past 2nd or 3rd gear.
- âś” Check Engine Light or Transmission Warning Light is on.
- âś” Diagnostic Trouble Codes (DTCs) are present, such as P0700, P0750, or other solenoid-related faults.
- âś” Inconsistent or complete loss of communication with the TCM.
- âś” Poor fuel economy and a feeling of sluggish performance.

Do I need to have this module programmed by a dealer?
Do I need to have this module programmed by a dealer?
No. This module arrives pre-programmed to your vehicle’s VIN. It is a true plug-and-play solution, saving you the time and expense of a dealership visit.
What is a core charge?
A core charge is a deposit you pay until you return your old part. We do not require a core charge for this TCM, so you can keep your old part without any hassle.
Will this fix a P0700 transmission code?
In many cases, yes. The P0700 code is a general fault code indicating the TCM has detected a problem. If the TCM itself is the source of the fault, replacing it will resolve the code and the underlying issue.
How difficult is the installation for a 2006 Rendezvous?
It’s one of the easier TCM replacements. Located under the air cleaner box, it’s accessible with basic tools and typically takes less than 30 minutes for someone with moderate mechanical skill.
What if I install this and still have problems?
While this TCM resolves the most common transmission electronic issues, problems can also stem from mechanical parts like solenoids or wiring. This module is backed by our one-year warranty, and our expert support team is here to help you diagnose any further issues.
