Sonnax Internal O-Ringed End Plug Kit 6R140

Sonnax Internal O-Ringed End Plug Kit for 6R140 Sonnax internal O-ringed end plug kit is designed to eliminate fluid leaks and restore hydraulic integrity in Ford 6R140 transmissions. Over time, OE end plugs wear due to repeated fluid pressure variations, spring motion, and valve impact, leading to critical pressure loss. The clutch latch valve bores and the solenoid feed pressure regulator valve bore in the 6R140 transmission are particularly vulnerable to this wear. When pressure drops due to end plug deterioration, shifting problems arise, and burnt clutches can occur. This Sonnax kit helps prevent these issues by ensuring a secure seal with O-ringed end plugs. Features & Benefits: O-rings provide a secure seal, minimizing leaks in worn OE bores. Prevents hydraulic pressure loss that can cause shift issues and clutch failure. Drop-in Zip Valve™ parts for quick and hassle-free installation. Kit Contents: (6) End Plugs (10) O-Rings (includes 4 extras) Common Symptoms Addressed
