Is your 2006 or 2007 Buick Rendezvous suffering from harsh shifts, 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 every shift with precision. When it fails, it can lead to poor performance, decreased fuel economy, and even leave you stranded in ‘limp mode’. Restore the smooth, reliable operation of your vehicle with this direct-fit, VIN-programmed T42 Transmission Control Module, service number 24252114.
Expert Pro Tip: Before installing your new TCM, disconnect the vehicle’s battery for at least 15 minutes. This helps reset the vehicle’s main computer and clears any stored adaptive learning values from the old, faulty module, ensuring the new TCM can establish fresh communication and optimal performance from the start.
