This heavy duty kit corrects the common problems with these transmissions; Increases torque capacity,Corrects/Prevents/Reduces: Goes to neutral under load, 3-4 slip; burned C3 clutches; sticks in one gear, smart clutch control valves for increased durability, SHORT-CRISP-SMOOTH-upshifts and kickdowns. Transgo® Allison 04-up Boost 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 are pushing the pressure limits
for clutch holding power. Sun Coast pressure regular shim to increase main line pressure and custom tool to help install.
