Required tool kit F-84741-TL13 is no longer in production. Check with your distributor for availability.
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.
Sonnax valve body layouts provide a detailed overview of individual units making it quick and easy to determine what’s available for the specific valve body you’re working on. See all Sonnax valve body layouts.
