The front stem of the Ford 4F50N, AX4N aluminum forward control valve bangs against the steel retaining clip when stroked. The force of this constant banging often causes the valve to warp and seize in the bore, as well as breaking the OE clip. No valve movement can result in a neutralling-out complaint, no 4th gear or a burned forward clutch. The Sonnax forward control valve kit 96206-07K corrects these problems.

Sturdier front spool on valve provides more than twice the spool-to-bore contact area
Design prevents valve warpage and/or seizure
Annular grooves are added to the spools to properly center the valve and prevent leakage
Drop-in Zip Valve™ parts install quickly and easily
