BD Diesel’s Allison Pressure Controller for 2011–2016 Chevy Duramax pickups boosts transmission line pressure up to 275 PSI under boost to reduce clutch slippage and extend transmission life during towing or high-load use. The unit activates only above 15 PSI boost to avoid added heat or odd shifting and installs quickly, plugging into factory connectors with no transmission relearn required for a plug-and-play upgrade.
