Sonnax O-Ringed End Plug Kit 6L45 6L50 6L80 6L90

Sonnax O-Ringed End Plug Kit for 6L45, 6L50, 6L80, 6L90 The OE end plugs in GM 6L45, 6L50, 6L80, and 6L90 valve bodies are designed to prevent critical pressure loss by sealing the bore. Over time, repetitive fluid pressure, spring motion, and valve impact cause wear at the end plug and bore mating surface, leading to hydraulic integrity loss and low pressure in critical circuits. In these transmissions, worn end plugs at the clutch regulator and clutch select valves can cause shift issues and burnt clutches due to leaking actuator/solenoid feed pressure and loss of Reverse and latch pressure. The Sonnax O-ringed end plug kit 104740-23K addresses these issues by restoring proper circuit pressures and reducing hydraulic losses. Key Features: Minimal end plug-to-bore clearance with an added O-ring for a positive seal Drop-in Zip Valve™ parts for quick and easy installation Symptoms Addressed: Shift concerns Burnt clutches Cause:Wear of the end plugs leads to leaks in actuator/solenoi
