The repetitious and varying actions of fluid pressure, spring motion and valve impact cause wear at the end plug and bore mating surface. Eventually the cumulative loss of hydraulic integrity leads to low pressure in critical circuits. In GM 6L45, 6L50, 6L80, 6L90 valve bodies, the end plugs at the various clutch regulator valves seal actuator/solenoid feed pressure that is critical to controlling the valve as gears change and clutches apply.
