Restore Your Transmission’s Performance and Reliability
Are you experiencing frustrating and unpredictable transmission problems? Issues like harsh shifting, getting stuck in gear, or a check engine light that just won’t go away can make driving a stressful experience. Your vehicle’s Transmission Control Module (TCM) is the brain behind every shift, and when it fails, it can sideline your truck or car. This replacement TCM is the definitive, hassle-free solution to get you back on the road with confidence. We take the guesswork out of the repair by pre-programming this module specifically for your vehicle using your VIN, ensuring a perfect, plug-and-drive installation.

Expert Insight from a 20-Year Technician:
I’ve seen countless GMT360 platform vehicles like the Envoy and Trailblazer come into the shop with these exact symptoms. The original TCMs are prone to failure from heat cycles and vibration over time. Many people try a used module from a junkyard, only to find it doesn’t work because it’s not programmed for their specific vehicle’s options (RPO codes). That’s why a VIN-programmed module is the only way to do this job right. It ensures the TCM communicates perfectly with the Engine Control Module and all other systems, just as it did from the factory. This isn’t just a replacement; it’s the correct, professional-grade repair that saves you time and future headaches. Getting a pre-flashed 2005 Envoy XL TCM is the smartest move for a successful, long-lasting fix.
