Restore Peak Performance to Your Buick Rendezvous
Is your 2006-2007 Buick Rendezvous suffering from harsh shifting, delayed gear engagement, or an illuminated 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 smooth gear changes, managing torque converter lockup, and ensuring overall driveline efficiency. When it fails, it can leave your vehicle stuck in limp mode, diminish fuel economy, and make driving unpredictable and unsafe.
This genuine quality GM T42 TCM, service part number 24235753, is the definitive solution to restore your vehicle’s factory performance. We eliminate the guesswork and costly dealership visits by pre-programming each module to your vehicle’s specific Vehicle Identification Number (VIN). This ensures a seamless, plug-and-play installation right out of the box, with the latest software updates from General Motors already applied. Your Rendezvous will operate with the precision and reliability you expect.
From the Diagnostic Bay
We had a 2007 Rendezvous come into the shop with classic transmission failure symptoms—slipping between gears and a P0700 code. The owner had already spent a small fortune replacing shift solenoids based on a generic code reading, but the problem persisted. After a quick diagnostic, we identified the root cause: the TCM itself was sending faulty signals. Instead of a costly transmission rebuild, the fix was this pre-programmed Rendezvous Transmission Module. Within 30 minutes of installation, the vehicle was shifting perfectly, and the customer was back on the road, saving thousands in unnecessary repairs.
Diagnosing a Faulty 2006-2007 Rendezvous Transmission Module
A failing TCM can manifest in various ways, often mimicking mechanical transmission problems. Before condemning your transmission, check for these common electronic symptoms.
