The ATS Co-Pilot Transmission Controller is built to give your 2006-2010 Silverado or Sierra 2500HD or 3500HD a major performance edge. This isn’t just a convenience add-on, it’s a performance game-changer that brings better shift quality, enhanced torque converter lock-up control, and a noticeable boost in overall drivability. By optimizing your Allison 1000’s pressure and lock-up points based on how you actually drive, the Co-Pilot takes the guesswork out and puts you in total control. Whether you're hauling heavy loads uphill or cruising through town, the results are smooth, responsive, and reliable. It helps reduce transmission heat and slippage, both of which are critical for long-term durability. For those looking to maximize performance without going full race mode, this is an ideal upgrade. Control Transmission Behavior With Smarter Data Inputs Technically speaking, the ATS Co-Pilot operates by taking direct signals from key sensors, MAP (boost pressure), VSS (vehicle speed), and TPS (throttle position)—to dynamically manage line pressure and torque converter clutch behavior. This results in more accurate and adaptive transmission responses under all driving conditions. The system is specifically tailored for the 6-speed Allison 1000 paired with the 6.6L Duramax engine, making installation and tuning straightforward. With the Co-Pilot active, the transmission benefits from better holding power, reduced slip, and improved shift timing. These improvements extend the life of clutches and help prevent overheating under load. It's also fully compatible with light towing and everyday driving, making it a practical solution for work and weekend warriors alike. For drivers looking to extend the performance and reliability of their drivetrain, this controller delivers results you can feel.
