Turbine hub FD-HT-40HSK adapts the Ford C5, C6, AOD and E4OD turbine to the 4R100 multiplate clutch assembly.

The Sonnax hub features an upgraded design that improves oil flow for piston release for 4R100 units. On the OE converter piston, release oil flows between the needle bearing and front cover. A large amount of bearing clearance is required for the oil to flow outward and release the piston. The Sonnax turbine hub is designed for improved piston release flow, allowing the oil to exit on the outside through angled holes like those on the 5R110W turbine hub. The needle bearing clearance can now be reduced to improve bearing life.
