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.
Although this valve does not require a reamer, use of the bore sizing tool 96206-BST (no longer in production) is highly recommended to quickly and easily resize the bore.
