Allison Boost Modifier Valve

This valve is the converter flow valve. This valve controls fluid to the converter clutch and cuts back pressure from 250 psi ( or so ) to 145 psi when the converter clutch applies. This valve will bring that pressure to a more acceptable 170-190 psi, and much more depending on application. We need this extra pressure because all you guys that are running big programs and nox are pushing the pressure limits for clutch holding power.
