NOTE: Proper operation of clutch boost/latch valves depends on correct pressure being supplied by shift solenoids. If troubles is found with pressure supply to these solenoids, Sonnax offers oversized AFL/solenoid regulator valve 124740-01.
Ford 6F50/55 and first generation GM 6T70/75 clutch boost/latch valves provide feedback pressure to their respective clutch regulator valves, balancing the regulators to assist with apply and release of the associated clutch. Pressure control solenoid fluid acts on the boost/latch valve to precisely control the amount of oil delivered to the balance end of the clutch regulator valve.
Excess wear in boost/latch valve bores can result in harsh shifts, slipping, burnt clutches, flares, and delayed engagement. Reconditioning the bore and installing Sonnax oversized clutch boost/latch valve 144740-23 restores the hydraulic control necessary for trouble-free shifting.
