Product Description
The ATS 601-924-4368 Allison Co-Pilot Transmission Controller is a performance upgrade designed for 2011-2015 6.6L Duramax trucks equipped with the Allison transmission. This advanced electronic controller enhances transmission performance by optimizing line pressure, improving shift timing, and reducing clutch slippage under load.
As power levels increase, the factory transmission tuning can struggle to maintain proper clutch engagement, leading to excessive wear and reduced performance. The ATS Co-Pilot solves this by actively monitoring engine load and dynamically adjusting transmission line pressure in real time to ensure firm, consistent shifts.
This plug-and-play module is ideal for towing, daily driving, and high-performance applications, providing increased transmission longevity and improved drivability without requiring complex tuning.
