BD Diesel Allison Pressure Controller - 2011-2016 Chevy Duramax 6.6L

If you're driving a 2011-2016 Chevrolet Silverado 2500 HD or 3500 HD with the 6.6L Duramax engine, you know these trucks can handle a lot. The Allison transmission in these vehicles is strong, but when you start adding power or using them for heavy towing, the stock line pressure can drop after shifts, leading to clutch slippage and potential damage. This BD Diesel Allison Pressure Controller is designed to address that by intelligently boosting line pressure when your engine is under significant load.

Unlike simpler devices that keep line pressure high all the time, this controller is only active when your turbocharger builds over 15psi of boost. This means when you're cruising or not under heavy load, the transmission operates with stock line pressure, avoiding harsh shifts and unnecessary heat buildup. When you do need it, it can raise line pressure up to 275psi, giving your transmission's clutches up to 115% more theoretical holding power. This helps prevent burned clutches and extends the life of your transmission, whether you're towing, on the street, or at the track.

Installation is straightforward, as this kit is fully plug-and-play, connecting directly to factory connectors without needing any special setup or transmission relearn procedures. It's a well-built unit designed to integrate seamlessly and provide a noticeable improvement in transmission durability under demanding conditions.
