Includes Valve, Sleeve and Spring. In Ford 5R55W and 5R55S units, line pressure from the manual valve is routed through the forward engagement valve in all forward gears prior to applying the forward clutch. Excessive wear at the valve bore or end plug can prevent solenoid feed oil pressure from correctly positioning the engagement valve or allow forward clutch feed pressure to exhaust. This reduced pressure can result in slipping or loss of forward gears, burnt forward clutches or delayed forward engagement. Sonnax forward engagement valve kit 56947J-26K will restore proper hydraulic function and prevent future wear. Sleeve manufactured from highly wear-resistant aluminum incorporates the end plug to prevent instability and wear, and provides more sleeve/valve contact for better hydraulic sealing. Valve is hardcoat anodized to reduce wear and incorporates annular grooves to hydraulically center itself in the bore.
