OE end plugs are designed to prevent critical pressure loss by capping the bore, while also functioning as a spring or valve stop. Repetitive spring motion, valve impact and fluid pressure variations cause wear between the end plug and bore mating surface, allowing vital pressure to escape the circuit. Ford Gen. 1 and 2 6F35 valve bodies have end plugs at the various clutch regulator valve bores which are susceptible to this wear. When actuator/solenoid feed pressure is allowed to leak due to plug deterioration, various shift concerns and burnt clutches will result in the affected circuit. Wear at the TCC regulator and clutch bypass valve end plugs allows valuable oil loss that leads to drivability concerns. Eliminate leaks and restore hydraulic integrity by installing Sonnax O-ringed end plug kit 147740-03K. Minimal end-plug-to-bore clearance with added O-ring for positive seal; Drop-in Zip Valve™ parts install quickly and easily
