The damper clutch control valve in Hyundai/Kia A4CF1, A4CF2 transmissions controls fluid pressure to the apply and release side of the converter clutch as well as to the cooler and lube circuits based upon the valve position. Solenoid modulator pressure works on the outboard valve spool diameter to stroke the valve into the converter apply position, and PCS signal pressure, combined with spring force at the inboard valve spool, work to stroke the valve into the converter release position. Wear at either of these critical valve-to-bore (casting or sleeve) locations will prevent proper functioning of the converter. The Sonnax oversized damper clutch control valve kit 84741-13K will restore the proper hydraulic clearance necessary to allow these pressures to work appropriately when used in a reamed bore.

• Valve is paired with a modified sleeve, incorporating an O-ring which provides positive sealing of solenoid modulator feed pressure
• Valve has lengthened spools for stability and sealing engagement in bores
• Annular grooves have been added to hydraulically center the valve in the bore, preventing future wear.
