Is your 2006-2009 Chevrolet Trailblazer shifting erratically, getting stuck in gear, or flashing a check engine light?

Expert Insight: Why Programming Matters
The T42 TCM is the brain of your 4L60E/4L65E transmission. Over time, heat cycles and vibrations can degrade its sensitive internal circuits, leading to the intermittent and frustrating issues you’re facing. A generic, non-programmed module from a local parts store won’t work—it can’t communicate with your vehicle’s other computers. Our VIN-specific programming loads the latest GM software calibrated precisely for your Trailblazer’s engine, tire size, and axle ratio. This ensures flawless communication and optimal performance from the moment you plug it in.
Don’t let a faulty TCM dictate when and how you can drive. Installing this pre-programmed 2006-2009 Trailblazer transmission control module is a straightforward job that most DIY mechanics can complete in under an hour, saving you hundreds in labor costs. Take control of your repair and get your SUV back on the road with confidence.
