Allison Cut Back Valve 2001-2004 [MAA1LUBST]

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. This valve is very important in high horsepower applications to hold the most extreme conditions.
