The Allison Pressure
Controller for 2011-2016 Chevy Duramax pick-ups delivers up to 275psi line
pressure inside the transmission, giving 25% to 115% 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. Installs quickly in under an hour.
