Restore Your Buick’s Shifting Performance
Is your 2006-2007 Buick Rendezvous suffering from erratic shifting, delayed gear engagement, or a frustrating 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 monitoring overall transmission health. When it fails, it can lead to poor performance, decreased fuel economy, and even leave you stranded in limp mode. This genuine quality GM T42 TCM, service part number 24235340, is the definitive solution to restore your vehicle’s factory performance and reliability.
From the Diagnostic Bay
We had a 2007 Buick Rendezvous come into the shop with a persistent P0700 code and complaints of harsh 1-2 shifts. The owner had already spent a significant amount of money replacing shift solenoids at another garage, but the problem remained. A quick scan showed communication errors with the TCM. Instead of chasing ghosts in the wiring, we swapped in a VIN-programmed T42 module. After a 20-minute installation and clearing the codes, the Rendezvous shifted like it just rolled off the assembly line. It’s a common scenario: mechanics often blame internal components when the electronic controller is the actual point of failure. This part saves time, money, and diagnostic headaches.
Common Symptoms of a Failing Transmission Module
- ✔ Harsh, erratic, or delayed gear shifts that disrupt your drive.
- ✔ The vehicle is stuck in a single gear, often referred to as “limp mode.”
- ✔ An illuminated Check Engine Light or Transmission Warning Light on your dashboard.
- ✔ Diagnostic Trouble Codes (DTCs) such as P0700, P0750, or other solenoid-related faults.
- ✔ A noticeable decrease in fuel efficiency due to improper gear management.
- ✔ Complete failure to shift up or down, or intermittent loss of communication with the module.
