The Allison Pressure Controller for 2011-2016 Chevy Duramax pick-ups delivers up to 275psi line pressure inside the transmission, giving 25 percent to 115 percent more theoretical holding power and help prevent burned up clutches - a great way to increase the longevity of the Allison transmission for towing, street and race applications. Unlike simple solenoid foolers or plugs which are active all the time, the Allison Pressure Controller is only operational when turbo boost exceeds 15psi, and, does not create extra heat when inactive or cause clunky/unusual shifts.
