Is your 2004-2005 Buick Rendezvous suffering from erratic shifting, getting stuck in gear, or displaying a check engine light?

Frequently Asked Questions
What is a Transmission Control Module (TCM)?
The TCM is the electronic brain of your automatic transmission. It receives data from various sensors on the vehicle and uses that information to control shift points, line pressure, and torque converter lockup for optimal performance and fuel efficiency.
How do I provide my VIN for programming?
After you complete your purchase, simply send us a message with your vehicle’s 17-digit VIN. We cannot ship your part until we receive this information, as the programming is specific to your vehicle.
Is any additional programming or learning procedure required after installation?
No. This module is programmed with the latest software and is ready to function as soon as it’s installed correctly. In most cases, no additional relearn procedures are necessary, making it a true plug-and-play solution.
What are the most common signs of a failing TCM?
The most common symptoms include the check engine light being on, harsh or delayed shifting, the transmission getting stuck in one gear (limp mode), and communication-related error codes stored in the vehicle’s computer.
