Restore Your Pontiac G6’s Shifting Performance
Are you experiencing frustrating and unpredictable shifting in your 2006-2010 Pontiac G6? Issues like harsh gear engagement, delayed shifting, or the dreaded “limp mode” are common indicators of a failing Transmission Control Module (TCM).

This VIN-programmed T42 TCM, part number 24240449, is the definitive solution to restore your vehicle’s original performance and reliability.
Expert Pro Tip
Before installing your new TCM, always disconnect the vehicle’s battery for at least 15 minutes. This helps reset the vehicle’s onboard computers and ensures a clean slate for the new module. After installation, use a quality OBD2 scan tool to clear any stored Diagnostic Trouble Codes (DTCs) from the system for optimal performance from the start.
