Is Your 2006-2007 Buick Rendezvous Shifting Erratically?
If your Buick Rendezvous is experiencing harsh shifting, getting stuck in gear, or showing a check engine light with transmission-related codes, a failing Transmission Control Module (TCM) is the most likely culprit. 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 frustrating and potentially damaging driving conditions. This genuine-quality GM T42 TCM, service part number 24241806, is the definitive solution to restore your vehicle’s transmission performance to factory standards.
From the Diagnostic Bay
We had a 2007 Buick Rendezvous come into the shop that was permanently stuck in 3rd gear—a classic case of ‘limp mode.’ The owner was worried about a complete transmission rebuild. After a quick scan, we pulled code P0700, a general transmission fault. Digging deeper, we found codes related to solenoid communication errors. Instead of a costly mechanical repair, we identified the original T42 TCM as the source of the electrical failure. We installed one of our VIN-programmed modules, and the vehicle was shifting perfectly within 30 minutes. The customer saved thousands and was back on the road the same day. This isn’t just a part; it’s a direct fix for a very common problem.
Symptoms of a Failing Rendezvous Transmission Control Module
A faulty TCM can manifest in several ways. If you’re noticing any of the following issues with your Rendezvous, it’s time to consider a replacement:
- ✔ Harsh Shifting & Delayed Engagement: The vehicle slams into gear, hesitates when shifting, or feels like it’s slipping between gears.
- ✔ Stuck in Limp Mode: Your transmission will not shift out of a single gear (usually 2nd or 3rd) to prevent further damage.
- ✔ Warning Lights: The Check Engine Light or a specific transmission warning light is illuminated on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs): You may see codes like P0700, P0750, or other solenoid-specific faults when using a scan tool.
- ✔ Poor Fuel Economy: Inefficient shifting caused by a bad module can lead to a noticeable drop in your vehicle’s MPG.
- ✔ Complete Loss of Shifting: In severe cases, the transmission may fail to shift up or down at all.
