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/solenoid feed pressure at the regulator valves and Reverse/latch pressure at the clutch select valves.
Solution:
The Sonnax drop-in O-ringed end plug kit restores correct circuit pressures, with O-rings providing additional sealing to reduce hydraulic losses.
