56947J-66K

In Ford 5R55W and 5R55S valve bodies, some end plugs and their bores are often worn due to small movements of the end plug within the bore. This motion is caused by continuous rapid fluctuations of fluid pressure, impact of a valve against the end plug face and spring forces where the end plug face is utilized as a spring seat. Additionally, the bore surface and end plugs can erode over time due to high pressure fluid squeezing between the bore and end plug. Sonnax O-ringed end plug kit 56947J-66K helps restore correct circuit pressures by replacing worn OE end plugs. The O-rings provide additional sealing to help prevent hydraulic losses in eroded bores.

• Restores proper end plug fit in OE bore
• O-Rings help reduce or eliminate leakage in eroded and worn OE bores
