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 ge ars change and clutches apply. When this fluid pressure is allowed to leak due to plug wear, various shift complaints and burnt clutches will occur within those specific circuits. Loss of Reverse and latch pressure occurs at worn plugs at the clutch select valves, preventing proper control of circuits as line pressure is routed through these valves to feed various clutches depending upon 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 Show more
