Our process of pre-programming this VIN Programmed T42 Transmission Control Module ensures it speaks the exact digital language of your car. It integrates flawlessly with the Engine Control Module (ECM) and Body Control Module (BCM), resolving software-based DTCs and ensuring all shift points and torque converter lockup schedules are perfectly calibrated for your specific application.
Don’t let a faulty TCM dictate your vehicle’s reliability. This high-quality, pre-programmed module is the most effective and efficient way to solve complex transmission electronic issues. Whether you’re fixing the family Tahoe, the workhorse Silverado, or the daily driver Malibu, this VIN Programmed T42 Transmission Control Module is the right part for the job.
