Sonnax 104740-23K, 6L45 / 6L50 / 6L80 / 6L90 O-Ringed End Plug Kit

The primary design function of the OE end plugs is to prevent critical pressure loss by capping the bore; they also perform a secondary function as a spring stop or valve stop. 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, and 6L90 valve bodies, the 6L90 O-Ringed Plug Kit at the various clutch regulator valves seal actuator/solenoid feed pressure that is critical to controlling the valve as gears change and clutches apply. Fluid pressure leakage due to plug wear causes shift complaints and burned clutches in specific circuits, affecting line pressure control and gear selection. Sonnax O-ringed end plug kit 104740-23K corrects these issues.

• Minimal end plug-to-bore clearance with added O-ring for positive seal
• Drop-in Zip Valve^™ parts install quickly and easily
