2011-2016 Allison transmissions utilize variable line pressure that adjusts to
different engine load to improve fuel economy. The problem with this is that it drops
line pressure after a shift, causing clutch slippage and failure in higher powered
trucks. The BD pressure controller module boosts line pressure up to 275psi when
the engine is over 15psi boost and runs stock pressure under normal conditions to
prevent harsh shifting.
The kit is fully plug-and-play. It plugs into factory connectors and requires no special
At wide open throttle, the stock strategy raises line pressure only for shifts, dropping
line pressure to different levels for each gear. First – 200psi, Second 220psi, Third
160psi, Fourth – 130psi, Fifth – 175psi, Sixth – 180psi. The BD pressure box keeps
line pressure at 250+psi when you are at full throttle to protect your transmission.
