Expert Insight: Why VIN Programming is Non-Negotiable
In modern vehicles like your Buick Allure, the TCM is the brain of the transmission, constantly communicating with the Engine Control Module (ECM) and other vehicle systems. A generic, non-programmed module simply cannot perform this job correctly. Our VIN-specific programming loads the exact software and calibrations your car was built with, ensuring all components work in perfect harmony. This critical step is the difference between a temporary fix and a lasting, reliable repair that restores factory performance and efficiency.

Where is the TCM located on my 2006-2009 Buick Allure?
On the Buick Allure for these model years, the Transmission Control Module is typically found inside or attached to the lower air cleaner housing in the engine compartment. Always disconnect the vehicle’s battery before beginning the replacement.
Will this fix a P0700 trouble code?
A P0700 code is a general fault code indicating the TCM has detected a problem. While this module often resolves the root cause of a P0700, it’s wise to have the specific transmission codes read to confirm the diagnosis. This part is designed to fix faults originating within the TCM itself.
