Hyundai and Kia vehicles with an A4CF1, A4CF2 transmission may exhibit a multitude of drivability complaints that can be caused by severe wear at the pressure reducing valve, allowing critical solenoid feed pressure to exhaust. The Sonnax pressure reducing valve kit 84741-10K restores the proper hydraulic clearance between the valve and bore, and prevents future wear.
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.
