The BD Diesel Allison Pressure Controller for 2011-2016 Chevy Duramax pickups enhances transmission performance by delivering up to 275 psi line pressure at wide-open throttle. This increase in pressure provides 25% to 115% more theoretical holding power, significantly reducing the risk of burned clutches during towing, street driving, or racing applications. Unlike simple solenoid foolers or plugs that are active constantly, the BD Diesel Pressure Controller operates only when turbo boost exceeds 15 psi, ensuring it does not generate unnecessary heat or cause shifting issues when inactive. Its dynamic activation preserves transmission longevity and maintains smooth shifting behavior.
Installation is straightforward, taking less than an hour, and does not require a transmission relearn. The controller includes a wiring harness designed for seamless integration with the vehicle’s existing electrical system. Its intelligent operation ensures that increased line pressure is only applied during high-boost conditions, optimizing both performance and component life. This device is ideal for heavy-duty use, providing increased torque capacity and enhanced durability without compromising drivability.
Designed specifically for 2011-2016 Chevy Silverado 2500 HD models with the Duramax 6.6L engine, this pressure controller is a reliable upgrade for fleet operators, towing professionals, and performance enthusiasts seeking improved transmission control and extended service life of their drivetrain components.
