Sonnax O-Ringed End Plug Kit 6R140

Sonnax O-Ringed End Plug Kit for 6R140

Sonnax O-ringed end plug kit is designed to eliminate fluid leaks and restore hydraulic integrity in Ford 6R140 transmissions. OE end plugs serve as bore caps and act as spring or valve stops, but over time, wear from repeated fluid pressure variations, spring motion, and valve impact can cause pressure loss. This loss of critical pressure can lead to shift issues and burnt clutches.

By installing Sonnax's upgraded end plugs with added O-rings, you can minimize clearance gaps, prevent fluid leakage, and ensure consistent transmission performance.

Features & Benefits:

• O-rings provide a positive seal, reducing or eliminating leaks in worn OE bores.
• Prevents hydraulic pressure loss that can lead to shift concerns and clutch failure.
• Drop-in Zip Valve™ parts for fast and easy installation.

• (5) 18mm Regulator End Plugs
• (8) 18mm O-Rings (includes 3 extras)
• (1) 20mm LPC End Plug
• (2) 20mm O-Rings (includes 1 extra)

Common Symptoms Addressed:
