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. Sonnax oversized damper clutch control valve kit 84741-13K restores the proper hydraulic clearance necessary to allow these pressures to work appropriately when used in a reconditioned 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 help center valve in bore to reduce future side-load wear
